The survey in underwater environment has always presented considerable difficulties both operative and technical and this has sometimes made it difficult to use the techniques of survey commonly used for the documentation of Cultural Heritage in dry environment. The work of study concerns the evaluation in terms of capability and accuracy of the Autodesk123DCatch software for the reconstruction of a three-dimensional model of an object in underwater context. The subjects of the study are models generated from sets of photographs and sets of frames extracted from video sequence. The study is based on comparative method, using a reference model, obtained with laser scanner technique.

Nowadays archaeological and architectural surveys are based on the acquisition and processing of point clouds, allowing a high metric precision, essential prerequisite for a good documentation. Digital image processing and laser scanner have changed the archaeological survey campaign, from manual and direct survey to a digital one and, actually, multi-image photogrammetry is a good solution for the underwater archaeology. This technical documentation cannot operate alone, but it has to be supported by a topographical survey to georeference all the finds in the same reference system. In the last years the Ca' Foscari and IUAV University of Venice are conducting a research on integrated survey techniques to support underwater metric documentation. The paper will explain all the phases regarding the survey’s design, images acquisition, topographic measure and the data processing of two Roman shipwrecks in south Sicily. The cargos of the shipwrecks are composed by huge marble blocks, but they are different for morphological characteristic of the sites, for the depth and for their distribution on the seabed. Photogrammetrical and topographical surveys were organized in two distinct methods, especially for the second one, due to the depth that have allowed an experimentation of GPS RTK’s measurements on one shipwreck. Moreover, this kind of three-dimensional documentation is useful for educational and dissemination aspect, for the ease of understanding by wide public.

Abstract. The metric documentation of architectural complexes requires today the use of several integrated survey methodologies. This need is an answer to the morphology of the object such as dimension, geometry, inaccessible areas and urban context. These properties inhibit the use of single surveying techniques and force the integration of Geomatics tools. In addition, the metric documentation of Cultural heritage objects not always requires uniform accuracy and resolution, therefore the integration of different surveying methodologies and techniques become the only effective solution both from a technical and economic point of view. The integration, that is today adopted as normal strategy, allows also the better understanding of the benefits which can arise to speed up the metric documentation of Cultural Heritage objects and the benefits that each of the possible surveying techniques can have thanks to the integration of the different potentialities. This study starting from an integrated survey, performed whit a combined use of Mobile Mapping System (MMS), Unmanned Aerial Vehicles (UAV) and Terrestrial Laser Scanner (TLS) and show the results of the comparisons between the possible achievable accuracies by using a correct integration between the different used technologies and the ones achievable by using the same techniques as independent tools.The case study is the architectural complex of the Ducal Palace in Gubbio (Italy), located upstream of the most important town square facing the cathedral in a very complex but realistic urban context.

The work presented here focuses on the analysis of the potential of spherical images acquired with specific cameras for documentation and three-dimensional reconstruction of Cultural Heritage. Nowadays, thanks to the introduction of cameras able to generate panoramic images automatically, without the requirement of a stitching software to join together different photos, spherical images allow the documentation of spaces in an extremely fast and efficient way. In this particular case, the Nikon Key Mission 360 spherical camera was tested on the Tolentini’s cloister, which used to be part of the convent of the close church and now location of the Iuav University of Venice. The aim of the research is based on testing the acquisition of spherical images with the KM360 and comparing the obtained photogrammetric models with data acquired from a laser scanning survey in order to test the metric accuracy and the level of detail achievable with this particular camera. This work is part of a wider research project that the Photogrammetry Laboratory of the Iuav University of Venice has been dealing with in the last few months; the final aim of this research project will be not only the comparison between 3D models obtained from spherical images and laser scanning survey’s techniques, but also the examination of their reliability and accuracy with respect to the previous methods of generating spherical panoramas. At the end of the research work, we would like to obtain an operational procedure for spherical cameras applied to metric survey and documentation of Cultural Heritage.

In sudden emergency contexts that affect urban centres and built heritage, the latest Geomatics technique solutions must enable the demands of damage documentation, risk assessment, management and data sharing as efficiently as possible, in relation to the danger condition, to the accessibility constraints of areas and to the tight deadlines needs. In recent times, Unmanned Vehicle System (UAV) equipped with cameras are more and more involved in aerial survey and reconnaissance missions, and they are behaving in a very cost-effective way in the direction of 3D documentation and preliminary damage assessment. More and more UAV equipment with low-cost sensors must become, in the future, suitable in every situation of documentation, but above all in damages and uncertainty frameworks. Rapidity in acquisition times and low-cost sensors are challenging marks, and they could be taken into consideration maybe with time spending processing. The paper will analyze and try to classify the information content in 3D aerial and terrestrial models and the importance of metric and non-metric withdrawable information that should be suitable for further uses, as the structural analysis one. The test area is an experience of Team Direct from Politecnico di Torino in centre Italy, where a strong earthquake occurred in August 2016. This study is carried out on a stand-alone damaged building in Pescara del Tronto (AP), with a multi-sensor 3D survey. The aim is to evaluate the contribution of terrestrial and aerial quick documentation by a SLAM based LiDAR and a camera equipped multirotor UAV, for a first reconnaissance inspection and modelling in terms of level of details, metric and non-metric information.

In the cultural heritage field the recording and documentation of small and medium size objects with very detailed Digital Surface Models (DSM) is readily possible by through the use of high resolution and high precision triangulation laser scanners. 3D surface recording of archaeological objects can be easily achieved in museums; however, this type of record can be quite expensive. In many cases photogrammetry can provide a viable alternative for the generation of DSMs. The photogrammetric procedure has some benefits with respect to laser survey. The research described in this paper sets out to verify the reconstruction accuracy of DSMs of some archaeological artifacts obtained by photogrammetric survey. The experimentation has been carried out on some objects preserved in the Petrie Museum of Egyptian Archaeology at University College London (UCL). DSMs produced by two photogrammetric software packages are compared with the digital 3D model obtained by a state of the art triangulation color laser scanner. Intercomparison between the generated DSM has allowed an evaluation of metric accuracy of the photogrammetric approach applied to archaeological documentation and of precision performances of the two software packages.

Recognizing the various advantages offered by 3D new metric survey technologies in the Cultural Heritage documentation phase, this paper presents some tests of 3D model generation, using different methods, and their possible fusion. With the aim to define potentialities and problems deriving from integration or fusion of metric data acquired with different survey techniques, the elected test case is an outstanding Cultural Heritage item, presenting both widespread and specific complexities connected to the conservation of historical buildings. The site is the Staffarda Abbey, the most relevant evidence of medieval architecture in Piedmont. This application faced one of the most topical architectural issues consisting in the opportunity to study and analyze an object as a whole, from twice location of acquisition sensors, both the terrestrial and the aerial one. In particular, the work consists in the evaluation of chances deriving from a simple union or from the fusion of different 3D cloudmodels of the abbey, achieved by multi-sensor techniques. The aerial survey is based on a photogrammetric RPAS (Remotely piloted aircraft system) flight while the terrestrial acquisition have been fulfilled by laser scanning survey. Both techniques allowed to extract and process different point clouds and to generate consequent 3D continuous models which are characterized by different scale, that is to say different resolutions and diverse contents of details and precisions. Starting from these models, the proposed process, applied to a sample area of the building, aimed to test the generation of a unique 3Dmodel thorough a fusion of different sensor point clouds. Surely, the describing potential and the metric and thematic gains feasible by the final model exceeded those offered by the two detached models.

Exploration of historical buildings during their life cycles is one of many aspects of the cultural heritage research. For studying different conditions of historical buildings over time, it is convenient to use photogrammetric surveys carried out in different time stages. Modern photogrammetric methods give the possibility to use archived analogue photogrammetric data, re-process them, and achieve new potentially valuable results with sufficient geometric accuracy and with high visual quality. The paper presents re-processing of analogue archival photogrammetric images captured by a metric camera in 1991 and compares the results to the new photogrammetric survey with a digital camera. The object of interest is Padise Abbey in Estonia. In 1991, parts of the abbey were in poor condition and conservation and renovation works were at an early stage. Nowadays, the abbey is partly renovated, and the results of the new photogrammetric survey give an opportunity to study two completely different conditions.

Abstract. Photography has always been considered as a valid tool to acquire information about reality. Nowadays, its versatility, together with the development of new techniques and technologies, allows to use it in different fields of application. Particularly, in the digitization of built heritage, photography not only enables to understand and document historical and architectural artifacts but also to acquire morphological and geometrical data about them with automated digital photogrammetry. Nowadays, photogrammetry enables many tools to give virtual casts of reality by showing it in the way of point cloud. Although they can have metric reliability and visual quality, traditional instruments &ndash; such as monoscopic cameras &ndash; involve a careful planning of the campaign phase and a long acquisition and processing time. On the contrary, the most recent ones, based on the integration of different sensors and cameras, try to reduce the gap between time and results. The latter include some systems of indoor mapping who, thanks to 360&deg; acquisitions and SLAM technology, reconstruct the original scene in real time in great detail and with a photorealistic rendering. This study is aimed at reporting a research evaluating metric reliability and the level of survey detail with a Matterport Pro2 3D motorized rotating camera, equipped with SLAM technology, whose results have been compared with point clouds obtained by image-based and range-based processes.

Abstract. The techniques and methods to capture and represent in a three-dimensional digital space the shape of objects belonging to Cultural Heritage have become more widespread, regarding both the economic and practical accessibility of technologies and equipment. At the same time, systems and tools have developed to integrate different 3D survey techniques that allow to achievement a complete acquisition of the tangible assets, considering the purposes of the survey, the required accuracy and the representation scale.The product of an integrated (image-based and range-base acquisition) and multi-scale (architectural and landscape scale) digital survey is a metric 3D reconstruction, potentially suitable for a broader ‘use’ and ‘user’ and not only for visualisation and documentation. According to this vision, the 3D model becomes a container of information, which include different type of data depending on the users and the aim of the work. The final result of this process can be the valorisation of the Cultural Heritage and its environment, through the access from experts and non-experts users. The aim of the article is showing the entire pipeline for 3D measurement, survey data acquisition, modelling, and representation of tangible assets and the related layers of information, as “best practice” to improve the Cultural Heritage knowledge, fruition, and sharing.

Syria is a country of many civilizations, Marie, Aramaic, Phoenician, Roman, Byzantine, Islamic, Ottoman civilizations. Unfortunally the recent war is the reason for many cultural heritage items to be destroyed, beyond the thausand civilian people killed. In 2010, just before the war, the A. made a touristic trip together with Crua (Recreational Club of the Ancona University). It was the occasion to make some fast documentation of some Syrian CH monuments. Mostly of the images were taken by the A. not to make a survey, but as a photographic report, as fast and complete as possible. For a regular survey project, the tripod, the spherical head should be used for the takings and the 3x3 Cipa rules should be followed, that occurred only in the three main projects, say the survey of the citadel walls in Aleppo, the survey of the Umayyads Mosque in Damascus, and the survey of the minaret of the Umayyads Mosque in Aleppo. All the other documentation surveys have been carried out with hand-held camera taking the dimension of the model from Google earth high resolution, when available. But, apart the regular surveys, due to the explosion of the unexpected war, the photographs taken in such a touristic way, have been used to try to get some usable plottings an restitutions and it worked successfully mostly of the times. These surveys could be useful in case of reconstruction and in case of lack of suitable alternative metric documentation. Because of the continuing threats, all six Syrian World Heritage properties were inscribed on the List of World Heritage in Danger, at the 37th session of the World Heritage Committee, held in Cambodia last June: Ancient City of Aleppo, Ancient City of Bosra, Ancient City of Damascus, Ancient Villages of Northern Syria, Krak des Chevaliers and Qal’at Salah El-Din ans finally the Site of Palmyra.

Apart the Ancient Villages of Northern Syria, the A. visited all the World Heritage sites and partly documented. Some of them have already been plotted, some are in the orientation stage, some have been documented only.

Abstract. The market of imaging and non-imaging sensors offers nowadays a wide range of products, which are constantly improving and growing. Given the recent advances in the miniaturization of devices for metric survey, and the relatively cheap COTS (Commercial Off The Shelf) solutions widely available, it is therefore crucial to optimally exploit, calibrate and evaluate the performance for 3D data acquisition of the new available devices. These issues are part of the latest research addresses of different Geomatics groups, with the aim to analyze and evaluate these new sensors, in order to discover their real potentialities which are not only connected to their interesting design, low price and small dimensions.According to the final objective of the research, which is the realization of 3D metric survey of a Cultural Heritage site using different techniques and methods, one small UAV (Unmanned Aerial Vehicle) and a portable TLS (Terrestrial Laser Scanner) have been employed. The acquisition strategies and the processing methods are discussed, and the quality of the achievable results is analysed, together with an evaluation of the sensors and the outline of the best practices and use cases scenarios.

Abstract. Nowadays, the employment of rapid mapping solutions for architectural survey is more and more considered, not only for the strong reduction of the primary data acquisition times, but also thanks to their adaptability to various contexts, especially in the framework of Cultural Heritage documentation where tailored solutions are required. The combined use of Mobile Mapping Systems (MMS), Unmanned Aerial Vehicles (UAV) for close range aerial image acquisition, and Terrestrial Laser Scanning (TLS) seems to be an effective solution for the architectonic scale compliant to the level of detail and accuracy of 1&thinsp;:&thinsp;200, and 1&thinsp;:&thinsp;100 scales. The present research tries to evaluate the use of a handheld MMS, the ZEB-Revo RT by Geoslam, an UAV, the DJI Mavic Pro, and a LiDAR system, the Faro Focus3D S 120 by CAM2. The complex case of the documentation metric survey of Palazzo Ducale in Gubbio, the Montefeltro’s Palace, now hosting the museum of itself, allows the comparison of the effectiveness of the used technologies.

Nowadays geomatic techniques can guarantee not only a precise and accurate survey for the documentation of our historical heritage but also a solution to monitor its behaviour over time after, for example, a catastrophic event (earthquakes, landslides, ecc). Europe is trying to move towards harmonized actions to store information on cultural heritage (MIBAC with the ICCS forms, English heritage with the MIDAS scheme, etc) but it would be important to provide standardized methods in order to perform measuring operations to collect certified metric data. The final result could be a database to support the entire management of the cultural heritage and also a checklist of “what to do” and “when to do it”. The wide range of geomatic techniques provides many solutions to acquire, to organize and to manage data at a multiscale level: high resolution satellite images can provide information in a short time during the “early emergency” while UAV photogrammetry and laser scanning can provide digital high resolution 3D models of buildings, ortophotos of roofs and facades and so on. This paper presents some multiscale survey case studies using UAV photogrammetry: from a minor historical village (Aielli) to the centre of L’Aquila (Santa Maria di Collemaggio Church) from the post-emergency to now. This choice has been taken not only to present how geomatics is an effective science for modelling but also to present a complete and reliable way to perform conservation and/or restoration through precise monitoring techniques, as shown in the third case study.

Conservation of modern and contemporary cultural heritage, which goes from design objects, to architecture, to cities and territories, is certainly a current topic and in the development phase as it is underway &ndash; in the same modernity &ndash; a process of systematic replacement of architectural elements, outcome of solutions then experimental, which today are reproduced with contemporary materials, analogous in the appearance, but intimately different especially in the technological content. The paper describes the particular case of La Tour de Meudon, better known as The Tower, (1966) by André Bloc, a contemporary architect of Le Corbusier, founder of L'Architecture d'aujourd'hui, who created his habitable sculptures. All his works mark the evolution of geometric abstraction to the free form, and they are still admirable testimonies of a journey that led him from architecture to architecture. His Architecture and his sculpture intertwine, opening the plastic unity of form in physical space&ndash;time. The survey is a fundamental moment for the knowledge of these hybrid architectures, where the structural component is hidden by its evident plasticity, as if it were a large sculpture with abstract and overlapping geometric shapes. Survey isn't only an analysis of geometries: it is instrumental to the other structural and material analyses since it provides a metric and topological basis on which to spatially locate the phenomena being studied. The integrated survey of the building (laser scanning, photogrammetry, topography) has allowed to document his project, contributing to the to definition of the actual construction characteristics and ascertain both the material consistency and the state of conservation.

Cultural heritage studies often require the analysis of buildings that have undergone several changes and alterations during their lifetime. This often implies the loss of architectural elements or the construction of new elements, which both change the characteristics of the former buildings. The recovery of lost elements or structures through virtual reconstruction is of paramount importance in both scientific and cultural applications. Novel procedures in surveying and photogrammetric processing including historical photogrammetry and historical terrestrial laser scanning offer powerful tools that enable the extraction of geometric information from historical documentation such as archival images. This paper presents the integration of a metric 3D model with information present in archival surveys of lost architectural volumes. The methodology implies the availability of historical plans representing the survey object at scales consistent with UAV surveys and featuring shared elements. The methodology used to frame these plans in the reference system of the UAV survey for an open source GIS environment is also described as well as the accuracy checks. Finally, the procedure followed for the virtual reconstruction of the Fortezza in a BIM environment, which produced a model derived from the integration of historic and current data, is described.

In the framework of the digital documentation of complex environments the advanced Geomatics researches offers integrated solution and multi-sensor strategies for the 3D accurate reconstruction of stratified structures and articulated volumes in the heritage domain. The use of handheld devices for rapid mapping, both image- and range-based, can help the production of suitable easy-to use and easy-navigable 3D model for documentation projects. These types of reality-based modelling could support, with their tailored integrated geometric and radiometric aspects, valorisation and communication projects including virtual reconstructions, interactive navigation settings, immersive reality for dissemination purposes and evoking past places and atmospheres. The aim of this research is localized within the “Torino 1911” project, led by the University of San Diego (California) in cooperation with the PoliTo. The entire project is conceived for multi-scale reconstruction of the real and no longer existing structures in the whole park space of more than 400,000&thinsp;m2, for a virtual and immersive visualization of the Turin 1911 International “Fabulous Exposition” event, settled in the Valentino Park. Particularly, in the presented research, a 3D metric documentation workflow is proposed and validated in order to integrate the potentialities of LiDAR mapping by handheld SLAM-based device, the ZEB REVO Real Time instrument by GeoSLAM (2017 release), instead of TLS consolidated systems. Starting from these kind of models, the crucial aspects of the trajectories performances in the 3D reconstruction and the radiometric content from imaging approaches are considered, specifically by means of compared use of common DSLR cameras and portable sensors.

In the last few years, new technologies have become indispensable tools for specialists in the field of cultural heritage for the analysis, reconstruction and interpretation of data but also for promotion of artefacts or buildings sometimes inaccessible or in a bad state of conservation. The discipline of geomatics offer many opportunities and solutions for integrated digital surveys and the documentation of heritage (point-based methods, image-based photogrammetry and their combination): These data can be processed in order to derive metric information and share them using databases or GIS (geographic information system) tools. This paper is focused on the description of combined survey methodologies adopted for the geometric and architectural documentation of the site and surviving structures of the Castel of Scalea (Cosenza, Italy). It is a typical context where traditional survey procedures do not fully succeed or require a longer amount of time and great effort if a high level of accuracy is requested: For this reason, aerial close-range digital photogrammetry enhanced by the GNSS (global navigation satellite system), and total station positioning systems have been used at various levels of detail for the production of a detailed 3D model and 2D thematic maps with an excellent level of in the positioning of the structures and in the architectural drawing. Thanks to the collected dataset, it was possible to better identify the building units (CF), to digitize the limits of the masonry stratigraphic units (USM), and to draw up a first constructive diachronic sequence hypothesis on which to base chronology. Moreover, some particular masonry techniques have been sampled and compared at the regional level with the aim to better dating of constructive expedients. It was finally demonstrated how the use of integrated methodologies allows us to obtain a complete and detailed documentation including information regarding not only architectural and geometrical features but also archaeological and historical elements, building materials and decay evidences—all useful as support of the interpretation of data.

Abstract. This paper deals with the use of Historical Building Information Modelling for digital reconstruction of buildings of rural architecture. The final Building Information Model (BIModel) can be used for research purposes such as Artistic and Historical Research, Building Archaeology Survey, etc., or can be used as basis for building restoration. The aim of the BIModel is to provide a reliable basis for future work.This paper presents practical experience gained during the implementation of the grant project “The Transformation of Rural Architecture with Emphasis on the Development of the 19th and 20th Centuries”, No. DG16P02H023. In the course of the project, datasets were collected from various sources and various types, usually photo documentation, cadastral maps, metric survey documentation, texts, etc. The interconnection of the datasets had to be ensured for future work. Therefore, solutions were sought to achieve this goal. Usually, complications occurred in sharing and exchanging data formats, georeferencing, selecting of resolution or Level of Detail (LoD), etc. In these cases, software tools and workflows were sought for integration between CAD or GIS, and vice versa.

This paper discusses some enhancements concerning 3D modelling, and the integration and comparison of 3D data from aerial and terrestrial sensors, developed by innovative geomatics techniques around the metric documentation of cultural heritage. In archaeology, it is interesting to deal with the considerable advantages of new multi-sensor approaches for the data acquisition and the management phases in terms of the sustainability (automated acquisition, quickness, precision, time and cost cutting). In particular, Unmanned Aerial Vehicles(UAVs)photogrammetry with the joint use of nadir and oblique cameras can be usefully combined with the large-scale details acquired by the terrestrial Light Detection and Ranging (LiDAR)in vast areas or complex objects, especially in mostly vertical sized objects. Here, we will report the results of an integrated 3D survey in an archaeological context in the Piedmont region of Italy. The Hercules Fountain is located in the gardens of the Venaria Reale (a Savoy Royal Palace included in the UNESCO heritage list) and has witnessed several events and historical phases during the past centuries–from its construction in the 16thcentury to its disuse and decline in the 17thcentury, right up to the 21stcentury when it was eventually brought back to light. The goal of the test is the creation of a3D continuous model of the site for documentation purposes, future consolidation, and enhancement projects finalised fora public promotion. To meet these strategic aims, a terrestrial laser scanning (TLS henceforth) survey has been designed together with multi-flights by a multi-rotor UAV and terrestrial close-range photogrammetry (CRP) acquisition to produce a highly detailed 3D textured model from which we have inferred standard 2D drawings, digital orthoimages, and further 3D products. In conclusion, the entire workflow and the outputs have been compared together to evaluate the effectiveness of each elaboration according to the different goals of the survey.

Abstract. The Italian legislation on Remote Pilot Aircraft Systems (SAPR: Sistema Areomobile a Pilotaggio Remoto), as in 2012, regulates the use of drones in controlled and uncontrolled airspace. In 2016, the regulation introduced simplified procedures for the use of ultra-light drones. These instruments are particularly widespread in the field of Cultural Heritage survey. In fact, according to the Italian regulations currently in force it is possible to pilot a drone of less than 300 grams without the need of a flight license and without a specific training course and medical examination and it is not required a special permit to fly in populates areas (although without flying over groups of people). Another possible explanation is the limited cost of these aircrafts and their easy availability on the market, both on the shelves of all electronic shops and in online stores.Following the boom of drones under 300 g, and considering the new European regulations also pay particular attention to a similar segment of Unmanned Aerial Vehicle (UAV) (in the future for aircraft under 250 g), it is important to evaluate the results that can be obtained through these small instruments and above all to evaluate which are the fields of application compatible with the technical limitations imposed by the need to lighten the components onboard (think in particular of the sensors of digital cameras).The purpose of the study is linked to the documentation of Cultural Heritage, in particular, we want to investigate the quality and metric reliability of photogrammetric surveys carried out through ultra-light drone images. Some application of UAV photogrammetry by ultra-light drones are showed in this paper and they deal with archaeological and architectural survey.

Abstract. The documentation of built heritage involves tangible and intangible features. Several morphological and metric aspects of architectural structures are acquired throughout a massive data capture system, such as the Terrestrial Laser Scanner (TLS) and the Structure from Motion (SfM) technique. They produce models that give information about the skin of architectural organism. Infrared Thermography (IRT) is one of the techniques used to investigate what is beyond the external layer. This technology is particularly significant in the diagnostics and conservation of the built heritage. In archaeology, the integration of data acquired through different sensors improves the analysis and the interpretation of findings that are incomplete or transformed. Starting from a topographic and photogrammetric survey, the procedure here proposed aims to combine the bidimensional IRT data together with the 3D point cloud. This system helps to overcome the Field of View (FoV) of each IRT image and provides a three-dimensional reading of the thermal behaviour of the object. This approach is based on the geometric constraints of the pair of RGB-IR images coming from two different sensors mounted inside a bi-camera commercial device. Knowing the approximate distance between the two sensors, and making the necessary simplifications allowed by the low resolution of the thermal sensor, we projected the colour of the IR images to the RGB point cloud. The procedure was applied is the so-called Nymphaeum of Egeria, an archaeological structure in the Caffarella Park (Rome, Italy), which is currently part of the Appia Antica Regional Park.

Abstract. The deep knowledge of Cultural Heritage, with historical research and interpretative analysis of materials, is fundamental to know the state of conservation and to plan potential restoration interventions. In the last years, thanks to the fast and continuous technological development, the metrical survey had a significant increase in this particular field: in fact, 3D digital acquisition allows to study some aspects otherwise difficult to investigate in a detailed way.In this research, we will explain the methodology used for the ceiling’s survey of the Sala Capitolare of the Scuola Grande di San Rocco in Venice, focusing on the support structure of Tintoretto’s paintings, anchored to a wooden system of Palladian trusses. The complexity of this Venetian architecture, its considerable dimension, the richness of decorations and the particular lighting conditions provided the opportunity of thinking about unconventional choices to apply from time to time and they required the integration of different methodologies: the laser scanning survey and the photogrammetric acquisition, together with a topographic network, allowed to obtain an adequate metric result for the study of the structure in its entirety. Furthermore, it was also decided to test image acquisition with a spherical camera for the documentation of the analysed architecture: this type of information, more related to a viewable aspect than to a metric one, can be presented together with traditional 2D representations to ensure a better enhancement of the achieved results.

Protection and conservation are not feasible without a deeper knowledge of the cultural heritage of the subject of intervention. A careful analysis of documentation, a detailed visual inspection of surfaces, and a systematic diagnosis of the inner properties are the basis for planning preventive strategies of restoration. Digital noninvasive techniques represent an advantageous tool with useful outputs to estimate the state of health of cultural heritage in order to minimize the progress of degradation. This paper deals with a 3D metric survey through photogrammetry and ground-penetrating radar (GPR) tests applied to the study of the trapezophoros with two griffins attacking a doe of Ascoli Satriano, a masterpiece of ancient art that needs to be protected. This work provided information on both visible and hidden defects, such as numerous cracks that affect the sculpture.

Indoor Gothic apse provides a complex environment for virtualization using imaging techniques due to its light conditions and architecture. Light entering throw large windows in combination with the apse shape makes difficult to find proper conditions to photo capture for reconstruction purposes. Thus, documentation techniques based on images are usually replaced by scanning techniques inside churches. Nevertheless, the need to use Terrestrial Laser Scanning (TLS) for indoor virtualization means a significant increase in the final surveying cost. So, in most cases, scanning techniques are used to generate dense point clouds. However, many Terrestrial Laser Scanner (TLS) internal cameras are not able to provide colour images or cannot reach the image quality that can be obtained using an external camera. Therefore, external quality images are often used to build high resolution textures of these models. This paper aims to solve the problem posted by virtualizing indoor Gothic churches, making that task more affordable using exclusively techniques base on images. It reviews a previous proposed methodology using a DSRL camera with 18-135 lens commonly used for close range photogrammetry and add another one using a HDR 360° camera with four lenses that makes the task easier and faster in comparison with the previous one. Fieldwork and office-work are simplified. The proposed methodology provides photographs in such a good conditions for building point clouds and textured meshes. Furthermore, the same imaging resources can be used to generate more deliverables without extra time consuming in the field, for instance, immersive virtual tours. In order to verify the usefulness of the method, it has been decided to apply it to the apse since it is considered one of the most complex elements of Gothic churches and it could be extended to the whole building.

The photogrammetric survey of architectural Cultural Heritage is a very useful and standard process in order to obtain accurate 3D data for the documentation and visualization of historical buildings. In particular, the integration of terrestrial close-range photogrammetry and Remotely Piloted Aircraft Systems (RPASs) photogrammetry allows to create accurate and reliable 3D models of buildings and to monitor their state of conservation. The use of RPASs has indeed become more popular in Cultural Heritage survey to measure and detect areas that cannot normally be covered using terrestrial photogrammetry or terrestrial laser scanner. The paper presents the results of a photogrammetric survey executed to document the monumental complex of Villa Lampedusa ai Colli in Palermo (Italy), one of the most important historical buildings of the town. An integrated survey by close-range photogrammetry and RPAS photogrammetry was planned and carried out to reconstruct the 3D digital model of the monumental complex. Different images configurations (terrestrial, aerial nadiral, aerial parallel and oblique to the façades) have been acquired; data have been processed to verify the accuracy of the photogrammetric survey as regards the camera calibration parameters and the number of Ground Control Points (GCPs) measured on building façades. A very detailed 3D digital model and high-resolution ortho-images of the façades were obtained in order to carry out further analysis for historical studies, conservation and restoration project. The final 3D model of Villa Lampedusa ai Colli has been compared with a laser scanner 3D model to evaluate the quality of the photogrammetric approach. Beyond a purely metric assessment, 3D textured model has employed to generate 2D representations, useful for documentation purpose and to highlight the most significant damaged areas. 3D digital models and 2D representations can effectively contribute to monitor the state of conservation of historical buildings and become a very useful support for preliminary restoration works.

Abstract. Despite the high standard guaranteed by 3D scanning technology, image based modeling establishes the most widely used technique for surface reconstruction, being a cheaper and more portable approach. The strong increase in the use of Unmanned Aerial Vehicles (UAVs), is increasingly affirming and consolidating over the years. Being more cheap and portable than the active sensors approach, the combination of photogrammetry and drones is widely used for different applications both for large scale mapping and for documentation of architecture and archaeological heritage. UAV based photogrammetry allows for rapid accurate mapping and three-dimensional modelling. Over the last two decades, the study of archaeological sites have benefited from the constant evolution of sensor-based surveying techniques, finding effective application for purely visualization purposes or for the extraction of metric data. The Punic-Roman temple "Sardus Pater Babai" in southern Sardinia (Italy), has been the subject of a massive anastylosis. The close-range photogrammetry technique, exploiting the images produced by a UAV consumer and the GNSS system data, has allowed the creation of metrically correct 2D and 3D models useful also for an effective visualization of the information. A series of ortho-images has been extracted in order to represent plan, elevations and cross-sections of the monument.

Recent results within the framework of the collaborative project The Complete Geophysical Survey of the Valley of the Kings (VOK) (Luxor, Egypt) are reported in this article. In October 2018, a team of geomatics and geophysics researchers coordinated by the Polytechnic University of Turin worked side by side in the VOK. Topographic measurements in support of geophysical surveys and the achievement of a very large-scale 3D map of the Eastern VOK were the two main objectives of the geomatics campaign. Innovative 3D metric technologies and methods, based on terrestrial laser scanning (both static and mobile) and close-range photogrammetry were employed by the Geomatics team. The geophysical campaign focused on the acquisition of Electrical Resistivity Tomography (ERT), Ground Penetrating Radar (GPR) and high spatial density Geomagnetic (GM) data. ERT new data around KV62, both inverted in 2D sections and added to the previous ones to perform a new global 3D inversion, confirm the previous results showing both conductive and resistive anomalies that have to be explained. GPR timeslices showed some interesting features in the area in front of the KV2 entrance where GM gradient map also presents localized anomalies. In the area SSW of the KV2 the GM gradient maps evidenced also a large semicircular anomaly which, up to now, has no explanation. The potentialities of using magnetic techniques as a complement to other non-invasive techniques in the search for structures of archeological significance have been explored. The application of modern and innovative methods of 3D metric survey enabled to achieve a complete 3D mapping of what is currently visible in the valley. The integration of 2D/3D mapping data concerning visible elements and hypothetical anomalies, together with the recovering in the same global reference system of underground documentation pertaining to the Theban Mapping Project, prefigure the enhancement of multi-temporal site representation. This strategy enables the fruition development of the already discovered archaeological heritage, using modern criteria of valorization and conservation.

Abstract. In the framework of restoration operations, valuable assistance can be supplied from innovative techniques and methods developed in the field of Geomatics. Over the years, this continuous collaboration has produced synergistic and interdisciplinary results that have been successfully contributing to heritage conservation and valorisation. In the case of the current research, thorough multisensory investigations have been performed in order to provide a deeper knowledge of the Green Room of the Valentino Castle in Turin and to support the planning of the future restoration works that will involve this valuable asset. In the framework of this experience, four LiDAR systems have been employed in order to evaluate the different results obtainable from the sensors. Additionally, a complete photogrammetric close-range survey has been carried out, and some tests were completed using a hyperspectral camera. The workflow followed during the current research is described in this paper, and a comparison between the obtained outputs is proposed, focusing on the characteristics of these metric products, useful and sometimes necessary in the framework of the restoration project. Besides, some considerations on the advantages and the issues connected with the use of these reality-based data as a starting point for HBIM (Heritage Building Information Modeling) model generation are proposed, along with some observations about the potentialities of a photogrammetric co-registration approach using spectrum technologies for deterioration/decay detection and monitoring of heritage.

Abstract. Researching historical archives for material suitable for photogrammetry is essential for the documentation and 3D reconstruction of Cultural Heritage, especially when this heritage has been lost or transformed over time. This research presents an innovative workflow which combines the photogrammetric procedure with Machine Learning for the processing of historical film footage. A Neural Network is trained to automatically detect frames in which architectural heritage appears. These frames are subsequently processed using photogrammetry and finally the resulting model is assessed for metric quality. This paper proposes best practises in training and validation on a Cultural Heritage asset. The algorithm was tested through a case study of the Tour Saint Jacques in Paris for which an entirely new dataset was created. The findings are encouraging both in terms of saving human effort and of improvement of the photogrammetric survey pipeline. This new tool can help researchers to better manage and organize historical information.

80 Background: High quality and safe medical care has been a consistent goal of the medical community at Virginia Mason Medical Center (VMMC). The Am Soc of Clinical Oncology (ASCO) has set out a list of criteria as part of Its Quality Oncology Practice Initiative (QOPI), which are increasingly being adopted as standards for quality measurement in the Oncology community. Our practice at VMMC participated in the QOPI quality metric survey, with the intent of measuring and enhancing cancer care delivery. Methods: We participated in the web-based QOPI quality metric during the September, 2013 and April, 2014 sessions. Chart abstraction was shared by the providers. Following the Sept session, our performance was analyzed, and targeted areas of improvement were collectively identified by all providers. Following the April session, the clinical note format was changed to incorporate a standard template, addressing areas of underperformance. Results: In the September 2013 session, the primary areas of underperformance were assessment of: a) pain, b) emotional distress, c) performance status (PFS), and d) documentation of staging. Following the April 2014 session, we noted improved performance in all these assessments. Thus, pain reporting rates improved from 40.6 to 61.2%; emotional distress screening from 37.3% to 42.8%; PFS documentation from 42.6 to 53.7%; and staging at initial diagnosis from 74.6% to 80.9%. However our areas of underperformance continued to lag 10 to 30% behind QOPI aggregate reporting rates. With the introduction of a structured note in the electronic medical record (EMR), further improvements are expected the results of which will be reported at the time of the meeting. On the positive side, chemotherapy education and discussion of risk/benefit were consistently areas of superior performance in our practice with our reporting rates being 10 to 40% higher than the QOPI aggregate. Conclusions: QOPI participation is a useful tool for improving and sustaining a high level of practice performance in oncology. Structured notes in the EMR maybe indispensable for maintaining a high level of compliance with performance measures.

e19191 Background: ASCO has implemented the Quality Oncology Practice Initiative (QOPI), a certification program established to evaluate oncology practice performance. Also, a growing number of accreditation (JCAHO) and merit-based organizations (MIPS) maintain falls risk assessment standards. Practices often lack the necessary resources to comply with required metric reporting standards. The study purpose was to document the effectiveness of using an electronic Patient Reported Outcome (ePRO) system to facilitate compliance with a core QOPI standard, documentation of smoking status by second office visit, and with JCAHO and MIPS falls risk assessment. Methods: This study used a retrospective, observational design with ePRO collected via the Patient Care Monitor (PCM), a web-based ePRO system linked to electronic medical record data. All study data were collected as part of routine clinical care at a community oncology practice during an 11-month interval (1/2019–11/2019). Patients at an initial clinic visit completed a tobacco usage survey and a brief falls risk survey on the PCM platform via a handheld e-tablet. Results: Overall, 6,613 unique patients completed the PCM survey (mean age 59; 33% male/67% female; 55.4% White, 38% Black). Cancer type was known for a subset of patients (22% breast, 9% hematologic, 4% lung, 5% colorectal, 3% prostate, 11% other types). Across the collected PRO measures, there was an over 98% completion rate with only 1-2% missing data. A relatively significant proportion (51%) indicated they had never used tobacco products and 15% indicated that they were current users. Among patients who ever used tobacco products, 34% indicated they smoked cigarettes, 4% smoked cigars, and 3% used electronic cigarettes. Over a fifth of patients (22%) indicated they had at least one fall over six months; 10% indicated having experienced one fall; 6% indicated two falls; 6% indicated 3 falls or more. 17% indicated they use an ambulatory aid and 12% reported a recent fall within the past 3 months. Conclusions: This study demonstrates that using an ePRO system is an effective way to screen for tobacco usage and falls risk and can be used to: 1) monitor health-related behaviors to enhance physician-patient communication; 2) provide an audit trail for QOPI, JCAHO, MIPS and other quality metric reporting. Automated collection of PRO data allows the healthcare team to focus their clinical time on patients showing increased risk. Overall, an ePRO system contributes to creating a culture of excellence at community oncology practices.

Abstract. The integrated survey carried out with both several technologies for the acquisition of metric data and information on materials and degradation pathologies, and procedures for data processing, offers the opportunity to be aware of the state of conservation of the built heritage following a procedure compatible with the protection and enhancement needs. The survey, if carried out in a quick way thanks to the recent videogrammetry software, ensures new and fruitful procedures for the cataloguing of monumental complexes for the purpose of risk mapping. Actually, the data captured by UAVs, together with the information obtained by the terrestrial measurement campaigns, if undertaken by the appropriate processes and the necessary skills, are an effective survey methodology for the criticality assessment of isolated architectural sites, like the strong medieval buildings which are still visible in the province of Enna, Sicily. Mostly abandoned and in the state of ruin architectures, which stand away from road infrastructure networks, they are often located in areas affected by depopulation, and risk to be forgotten and to disappear due to the inexorable passage of time. This work, through several case studies on relevant castles, wants to illustrate a project aimed at the knowledge and documentation of these important testimonies of the culture of the island, which only if suitably safeguarded and controlled would become the nodes of a widespread and sustainable tourist system, accessible to a wider public.

The themes of the conference provide an opportunity to exchange views on topics of study in which multidisciplinary contributions of geomatics and restoration contribute to the cognitive process aimed at the conservation of cultural Heritage. In this regard, the contribution exposes research aimed at understanding the documentation and the enhancement of unique architectural – landscape patrimony kept in the Abruzzo mountains. It is about the numerous spiritual retreats established by Pietro da Morrone, Pope Celestino V, mounted among unpassable rocky walls, where the architecture blends with its natural environment camouflaging with it. The analysis refers, specifically to the aspects of survey conducted during the years with the aid of integrated methodologies, able to allow the acquisition, management and comparison of the data. The analysis refers, specifically, to recent digital acquisitions involving the development of San Bartolomeo in Legio, on the slopes of Majella near Roccamorice detected with the use of comparative Agisoft Photoscan and Pix4d software, with shots taken with drones of different sizes, able to mount professional photographic cameras and associate to each picture the coordinates Gps of the point of shooting. Follows a confrontation between a survey carried out with 3d laser scanner, Faro Ls1105, and described acquisitions, obtained from ground and from drone with Photoscan, in order to compare the two scans and the metric differences obtained with the two methods.

The documentation of Cultural Heritage asset is the basis for all the interventions and policies on Cultural heritage conservation and management. The documentation is mainly based on historic knowledge and metric survey. As far as historic knowledge is concerned many information are still recorded and preserved inside written documents that are usually not easy to reach and correctly understandable by all the experts that have specific responsibilities on Cultural Heritage. The digitalization of documents (hardly faced in the last years) is not sufficient to guarantee the effective access to the historical information useful inside a documentation process. The documentation always needs an historical interpretation based on a critical reading produced by linking heterogeneous materials. Iconography also is an important source when it is correctly interpreted and linked to other sources. IT development and digital technology diffusion allowed offering new way to record, organize and share historical information: GIS and 3D modeling can be used as standard approaches to transfer the historical knowledge in a proper way to specialists involved in Cultural Heritage conservation and management. They have been generally used as tool to represent information for different targets, the ones mostly for specialized users, the others for edutainment. GIS are largely diffused yet in the Cultural Heritage management, and 3D modeling is wide spread used in museums communication. Nevertheless, both of them have more potential. They could be integrated in order to manage different data set related with the same matter. They could be used to make new research by surveying and improving interpretation in a way ready to transmit the outcomes. To produce a new generation of affordable digital historical products is necessary that the GIS and 3D modeling design and realization would be developed in a multidisciplinary approach that must be explained and demonstrated to the people that in the future will offer to the community this expertise. The paper describes a teaching and research training experience started two years ago at the Politecnico di Torino in the master course on Architecture (Conservation).

Abstract. The ability of managing big amounts of metric information coming from a LiDAR survey and the ability to reproduce high quality 3D models from them are still vivid problems to solve. Is it possible to create detailed models, geometrically and metrically correct, without using a large amount (often redundant) of metric data, such as massive point clouds? Obviously yes, but there are several ways to create a fitting 3D model for a specific research. A good solution is given by NURBS based algorithms that ensure high details of modelling. However, NURBS models can't be used directly on BIM platforms, because they need to be parametrized. In this sense, a parametric model is based on real measurements but each object could be interpreted and approximated based on objective and subjective (critic) view and also based on LODs (levels of detail or development) concerning a particular analysis. This kind of modelling of Cultural Heritage assets, fundamental for HBIM creation, need to be correctly planned especially for classification and definition of its historical features connected to an informative system, because nowadays information and then the semantic dimension are a necessary key points towards documentation analysis. Established this brief introduction, this schematic work will focus on the analysis of FreeCAD open BIM software and Rhinoceros as NURBS 3D modeller for Cultural Heritage is concerned, and whether and how they could integrate their tools for the purpose of managing dynamic high detailed data for the creation of an HBIM platform.

Abstract. The Laboratory of Geomatics for Environment and Conservation of Cultural Heritage (GECO &ndash; University of Florence) has been involved since 2011 in a process of technological transfer in collaboration with the Oficina del Historiador de La Ciudad de La Habana (OHcH). The know-how transfer concerning geomatics techniques for documentation and surveying of cultural heritage is of fundamental interest for the principal Institution designated to the protection of Havana historical centre. The first project (2011&ndash;2014) was mainly focused on the formation of specialized technicians from OHcH in the use of Terrestrial Laser Scanner (TLS), for documentation purposes of monumental and architectonical heritage. The ongoing project, INNOVA CUBA &ndash; “International and intersectoral intervention for the safeguard of the cultural heritage of the country” started in 2017, is funded by AICS &ndash; Italian Agency for Development Cooperation and coordinated by ARCS &ndash; Culture Solidali. The introduction of digital close-range photogrammetry represents the natural progression of this educational process, thus implementing the range of innovative surveying technologies available, in terms of instruments, software and technical know-how. The two-weeks training experience in Havana (2018) provided the participants, technical staff from OHcH and other institutions, all the necessary knowledge to be autonomously able to choose the suitable surveying technique, depending on object characteristics and on available devices, to correctly plan the survey and evaluate its metric quality. A final workshop, for a wider audience, was the opportunity to introduce future crowdsourcing photogrammetric activities, to improve the sensitivity and engagement of local community towards heritage protection and valorisation processes.

This article aims to critically examine the entire methodology of very large scale (1:1) surveying and documentation of mosaic surfaces. The term ‘survey’ should be read in its broadest and most complete and sense, including the phases of measurement and data processing as well as management and use of these data for the purposes of preservation and maintenance. The case study presented here took place at St Mark’s Basilica (Basilica di San Marco), in Venice, where mosaic flooring, wall and vault decorations have been surveyed on two separate occasions. These two experiences shared a common goal (a full-scale survey of the mosaic decorations) but differed in terms of the methodologies used, chiefly due to the technological developments of recent years. All this, therefore, lends itself to a methodological reflection and critique of the ways in which surveying technology has evolved over time. It enables to conduct surveys that would, just a few years ago, have been inconceivable due to their size and complexity. This article describes in detail current surveying processes, which includes the use of a multi-scale “image-based” approach, “re-topology” methods such as non-uniform rational B-spline (NURBS) and a tailor-made Building Information Modeling (BIM) system. This system allows the direct use of a three-dimensional (3D) model of the Basilica within the maintenance process of the monument itself with the options to georeferencing information, extract basic metric data and catalogue all its mosaics.Highlights:<ul><li>Modern digital photogrammetric techniques enable the acquisition of very complex objects, not only in terms of form but also in terms of material.</li><li>To obtain high resolution orthophotos, it is necessary to accurately take care of all the stages of the process: photographic acquisition, surveying, modelling and orthographic reprojection.</li><li>High resolution images and detailed 3D models can benefit from a complex BIM system for the management of all data.</li></ul>

Abstract. The 3D-SLAM-based recording of historic gardens and architecture with the scope of geometric and quantitative analysis of typologies of garden architecture in the context of a designated cultural landscape will be presented. This will be illustrated by case studies of three baroque gardens of buildings belonging to the Cistercian order.The ‘Centre for Heritage Conservation studies and Technologies’ (KDWT) at the University of Bamberg is cooperating with the Cisterscapes project to deliver metric surveys, architectural comparison of the historic gardens as typical feature of the agricultural granges. The survey and research were conducted in autumn 2020 and 2021 in two granges in Franconia (Bavaria, Germany) as well as on the monastery of Ebrach.For the recording, SLAM technology, was the preference and a GeoSLAM ZEB Horizon was used. It is a solution using the data sequence acquired during motion for estimating the relative poses in real time. The case studies served not only to generate an accurate output to be explored in the Cistercian Cultural Heritage Project, but also as test of the instrumentation to ascertain best practices of the instrument. 3D digital documentation will contribute to the holistic understanding of garden plus architecture ensembles. 3D data analysis will be approached from an art-historical and architectural viewpoint, conclusions shall be drawn from interdisciplinary cooperation. This comparative research will serve to find similarities or differences and establish prototypical elements of these typical elements of Cistercian Cultural Landscape. The 3D records can also be used as basis for future monitoring and development of a new garden care concept taking heritage conservation into account. Heritage, in its many forms, is not only a representation of the past, but a connection or reconnection with a past that is active and alive in the present. It shapes and reshapes people’s sense of place, sense of belonging and cultural identities at the local and national level.

The research project VisualVersilia 3D aims at offering a new way to promote the territory and its heritage by matching the traditional reading of the document and the potential use of modern communication technologies for the cultural tourism. Recently, the research on the use of new technologies applied to cultural heritage have turned their attention mainly to technologies to reconstruct and narrate the complexity of the territory and its heritage, including 3D scanning, 3D printing and augmented reality. Some museums and archaeological sites already exploit the potential of digital tools to preserve and spread their heritage but interactive services involving tourists in an immersive and more modern experience are still rare. The innovation of the project consists in the development of a methodology for documenting current and past historical ages and integrating their 3D visualizations with rendering capable of returning an immersive virtual reality for a successful enhancement of the heritage. The project implements the methodology in the archaeological complex of Massaciuccoli, one of the best preserved roman site of the Versilia Area (Tuscany, Italy). The activities of the project briefly consist in developing: 1. the virtual tour of the site in its current configuration on the basis of spherical images then enhanced by texts, graphics and audio guides in order to enable both an immersive and remote tourist experience; 2. 3D reconstruction of the evidences and buildings in their current condition for documentation and conservation purposes on the basis of a complete metric survey carried out through laser scanning; 3. 3D virtual reconstructions through the main historical periods on the basis of historical investigation and the analysis of data acquired.

The new tools for 3D survey and modelling (as portable scanners and software packages), often in combination with diagnostics, are nowadays able to provide indispensable elements for the study of archaeological artefacts; their applications to museum’s heritage can be also useful to integrate the traditional graphic documentation and contribute to enhancement and dissemination. This paper shows the benefit of using the aforementioned tools to study the peculiar clay mask No. 11114-E, discovered in 1973 in the Greek necropolis of Lipára, inside tomb No. 1558. The specimen, now exhibited in the Classical Section of the Aeolian Museum, is considered unique both in the Aeolian Islands and in the ancient Greek world, as it is the only one merging two half faces attributable to different characters. This feature, unknown at the time of discovery, has been highlighted in 2018, thanks to a restoration intervention by which a hard concretion layer covering a large portion of the mask surface was removed, bringing to light a smiling young half-face next to an old one with Silenic features. In 2019, the mask was surveyed in situ through a portable and performing laser-scanner arm (the QuantumTM FaroArm by FARO) to produce a high-resolution 3D model useful to enhance the reading of the two halves (not evident enough, due to its state of preservation). The data processing was performed using the Geomagic Wrap software, able to align and merge multiple scans into a single model and to export results in multiple formats, easily shareable and viewable in free software or via the web. Finally, thanks to this method, the successful generation of a digital replica was performed; the resulting replica is useful for dissemination and as a support for the hypothetical reconstruction of the two prototypes taken as models by the craftsman who created the mask.Highlights:<ul><li>A 'mobile laboratory’ consisting of portable equipment has been set up to perform 3D metric surveys on a selection of artefacts preserved at the Museum of Lipari.</li><li>By means of an ultra-precision laser-scanner arm, a 3D survey on a miniaturistic double-faced mask, belonging to the classical theatrical terracotta, has been performed.</li><li>A geometrically accurate and realistic 3D final model has been created. This helped the study and reconstruction of the two characters composing the mask.</li></ul>

Extended Abstract:Ali Atar, Warden of Loja and Lord of Zagra, was born around 1393. He was one of the principal military leaders of the Nasrid period and came to join the Grenadine Royal House by marrying his daughter Moraima with Boabdil, the last King of Granada. He died in the battle of Lucena in 1483, where one of the magnificent jineta swords of Andalusí manufacture was snatched, which is now conserved and located in the collection of the Toledo Army Museum (MUSEJE). The MUSEJE collections house important scientific, technical, historical and artistic heritage. The historical military heritage needs for its protection, preservation and valorisation the adaptation of new resources and benefit from the usage of new digital technologies. The physical conservation is no longer enough for a resource as valuable as cultural heritage; it needs to be complemented with a comprehensive digital preservation in all its forms, being essential and necessary for its proper safeguard. The virtual era currently emphasizes its presence in the digital documentation, preservation and dissemination of our cultural heritage. In particular, we have oriented and activated it on the historical military heritage, knowledgeable and narrator of our history, of its treasures, and of their relationship within the society as important representations of social and dynastic status. This paper is centred in the 3D digitisation by means of digital photogrammetry and 3D modelling of a historical military weapon. Aided by photogrammetry and information and communication technologies (ICT), we will achieve precise geometric documentation and 3D models that are geared towards research, education, diffusion and the preservation of heritage as important and unknown as is historical military heritage. Photogrammetry gives us the opportunity to bring to light the Ali Atar’s sword, one of the most relevant artistic manifestations belonging to the Nasri armament (Fig. 1, Table 1). The multi-view close-range photogrammetry is key to virtualise this jewel and also to contribute to the democratisation of the museum through the web dissemination of its content in a personalized way.Materials such as metals and precious stones, and gold techniques present in the Andalusian weapon required a particular photogrammetric data acquisition using a light booth and polarizing filter (Fig. 10), as suggested for the latter by <a href="file:///E:/PC%20Port%C3%A1til%20Poli/Mis%20documentos/VAR/En%20Curso/Revisi%C3%B3n/10028/VAR_In_Press_10028.docx#Guidi_2014">(Guidi, Gonizzi, & Micoli, 2014)</a>. This setup brought a substantial improvement when dealing with highly reflective materials such as the metallic blade of Ali Atar's jineta sword. The use of the polarising filter attenuated the light that affects and reflects in the piece, benefiting both data acquisition and processing to deliver 3D models. We offered some results ready to safeguard, preserve and disseminate the jineta sword as a high-quality 3D model (Fig. 13), with submillimetre precision from which to obtain all the necessary metric deliverables. From the dense point cloud, two meshes were delivered: i) a homogeneous high resolution mesh keeping all the original features for archiving, conservation and research, and ii) a medium resolution mesh for web-based visualisation and dissemination. The aim was to achieve a detailed geometric documentation as well as complete and accurate 3D models (Fig. 29) for web repositories (<a href="https://skfb.ly/ZzzA">https://skfb.ly/ZzzA),</a> orthoimages (Figs. 30 and 31) that allow us to plot from CAD programs all the ornamental and decorative information of the piece (Figs. 32 and 33). In addition, we present some results related to monitoring and evaluation of changes in the state of conservation of the piece (Figs. 34, 35 and 36), extending the survey to preventive conservation studies.This research proves the value of geometric documentation techniques for the democratisation of museums. It contributes to improving the research processes, opening a new line of study. From this point we can rebuild the past through the virtuality, being able to mark and confirm historical hypotheses. These techniques offer the chance to give value to relevant and singular pieces in and out of museums. Both heritage and virtual archaeology are fundamental pillars to delve into the future of education and knowledge.

Objective To assess the impact of implementation of a “1-step” documentation query system on comorbidity capture and quality outcomes within the Department of Otolaryngology–Head and Neck Surgery. Methods Implementation of the 1-step documentation query system was instituted for all otolaryngology–head and neck surgery faculty at a single institution. Individual query responses and impact metrics were analyzed. Departmental case-mix index (CMI), risk of mortality (ROM), and severity of illness (SOI) were collated over a 14-month implementation period and compared to a 12-month preimplementation period. Results A total of 226 documentation queries occurred during the program pilot period, with an 86.7% response rate. Of queries with a response, 91.0% resulted in a significant impact for the hospitalization diagnoses-related group, ROM, or SOI. Departmental CMI increased from 2.73 to 2.91 over the implementation period, and observed/expected mortality ratio decreased from 0.50 to 0.42 pre- to postimplementation. Discussion With increasing emphasis on quality metrics outcomes within the United States health care system, there is a need for institutions to accurately capture the complexity and acuity of the patients they care for. There was a positive change in quality outcomes metrics, including ROM, SOI, and CMI over the first year of deployment of the 1-step documentation query process. Implications for Practice Clinical severity metrics are becoming increasingly important to otolaryngologists, as insurers move to severity-adjusted profiles. The 1-step documentation query process provides a reproducible and effective way for clinical documentation specialists and physicians to collaborate on improving departmental clinical severity metrics.

257 Background: Many barriers to adherence to quality standards exist, including patient, provider, and system barriers to delivery and documentation of timely, evidence-based care. Gaps in clinician knowledge about care standards likely contribute to non-adherence. Methods: Prior to an intervention study, providers completed a questionnaire assessing their knowledge of and ability to influence institutional attainment of specific QOPI metrics. Providers’ ability to influence meeting each of 9 QOPI metrics was measured on a 1-4 scale from “not at all” to “significantly” able to influence. Providers also identified barriers to meeting each metric. Results: 28 providers completed surveys; 43% from a university based cancer center and 57% from a community based cancer center. Respondents include oncology MDs (43%), NPs (7%) and RNs (46%). Perceived ability to influence 9 quality metrics are detailed in the Table below. Providers felt the least able to influence metrics related to fertility preservation with 32% reporting no influence. 21% credited ‘lack of visibility into current data’ to be a main barrier. Providers reported limited ability to address emotional well-being with 36% reporting a ‘lack time to assess/manage’. Providers felt most able to influence physical symptoms such as pain. Conclusions: The most frequently cited barriers to meeting study-specific quality metrics included lack of a) current knowledge/latest evidence and, b) time to assess/manage. Employing methods to address these barriers may improve quality care. In part 2 of this study providers engage with the Carevive Care Planning System, designed to address these barriers by assessing patient needs at the point of care and providing evidence-based recommendations for treatment.

Metric surveys are a key component in Cultural Heritage. Metric surveys are in fact a basic input for a wide range of activities, from documentation to study, from restoration to valorization, that rely on the current condition of the monument. In recent years, laser scanning and, more recently, digital photogrammetry offered new perspectives, widening the perspectives of 3D Cultural Heritage recording. Digital technologies provide new ways to collaborate, record excavations, and restore artifacts, and in such a way they are transforming the way Cultural Heritage practitioners (researchers, archaeologists, curators) work. This paper attempts to review the methods for 3D digitization that are today available and discuss the possible use of 3D models beyond the pure extraction of reliable and accurate measures.

Three-dimensional metric models of real physical objects are actively used when solving various tasks in the process of a person's professional activity. In the construction industry, 3D modeling helps to capture all life cycles of buildings from engineering surveys to design, operation and demolition work. Three-dimensional models allow quickly performing all the necessary measurements in a computer environment, provide the ability to build two-dimensional drawings and make changes to design documentation. Among all types of three-dimensional models, there are separately those that allow storing various attributive information about an object in addition to geometric information, significantly automate the process of many engineering calculations using a three-dimensional model and provide the ability to automatically create various types of documentation. These types of three-dimensional models are called building information models (BIM). The most appropriate method is laser scanning as a data source for creating BIM. The technique of three-dimensional modeling based on laser scanning data is discussed. The advantages of BIM over simple three-dimensional models created in specialized software for processing laser scanning data and computer-aided design systems are analyzed.
