Making smart and informed decisions often requires the integration and analysis of large amounts of data. However, integrating these data is rarely straightforward, mainly because of heterogeneities in data structure and format. In this study, we focus on two widely used data formats by municipalities to store digital maps of their infrastructure: Computer-Aided Design (CAD) and Geographic Information Systems (GIS). While most municipalities still maintain infrastructure data in CAD format, many have started converting them to GIS since GIS includes geographical coordinates. However, the inherent differences between these two formats pose challenges to accurately converting information from CAD to GIS. The main goal of this study is to develop a procedure to help municipalities to perform CAD-to-GIS conversion. To that end, potential problems in CAD-to-GIS conversion were first identified through interviews with practitioners at different U.S. municipalities and through a literature review. Taken together, we propose the C2G framework to streamline the conversion process while minimizing information loss. The framework consists of five stages, and the execution of this framework and tasks involved in each stage are explained. Moreover, we apply the framework to real-world underground stormwater infrastructure data obtained from the University of Illinois at Chicago (UIC) to illustrate the framework’s applicability. The case study explains details about the technical difficulties we encountered in the process and provides recommendations to circumvent those difficulties. The results from the case study showed that the C2G framework was able to successfully convert CAD data to GIS data. Although the framework is developed specific to the needs of CAD/GIS practitioners in the US municipalities, it can be adopted in most CAD-to-GIS conversion situations. The information learned during the interviews supports the need for a standard CAD-to-GIS conversion process. The contribution of this study is to fill this gap by developing a generalized framework to carry out CAD-to-GIS conversion which only requires basic knowledge of CAD and GIS.

The paper deals with current issues of spatial data modelling and management used by spatial management applications. As a case study for explaining the problem, we use comparison of two main groups of software tools covering this area GIS and CAD systems - and the posibilities of their integration. Studying its functionality, we have found two main problematic issues. The first of them is the density distribution characteristics of stored data according to described area. CAD systems are oriented towards modeling individual man-made objects and structures with relatively high level of detail, so the data stored covers small areas with huge amount of information. On the other side GIS applications maintain large-scale models of real world with significantly lower amount of detail. Here the density distribution of data coverage is better balanced. So the combination of described different densities is the first problem. The second watched issue is the way of storing spatial data. While CAD data are usually stored in individual files (like DXF, IGES), GIS data tend to be stored in files or realtional databases. The question we see is, if it is possible to store CAD data along with GIS data in the same database in spite of different distribution densities and different data models. Our paper describes ways of solving this problem.

Texas is botanically diverse with approximately 5500 native plants identified: east Texas contains about 40% of the total. While most species are stable, many are classified as rare, threatened, vulnerable, or endangered. Databases for east Texas plant communities and vegetative analyses are numerous. However, they are not yet integrated into easy-to-sort-and-query computer files. Computer-Assisted Drafting (CAD) and Geographic Information Systems (GIS) technology offers powerful applications to the storage, management, and spatial analysis of species inventories, plant community dynamics, and long-term habitat monitoring. At SFASU, the College of Forestry's GIS Center is being utilized to develop comprehensive east Texas resource inventories on a ten-station HP Apollo/ArcInfo platform. In the horticulture program, a twenty-station PC/AutoCad teaching laboratory is being used to create layered maps of the SFASU Arboretum, the on-campus landscape and off-campus plant communities. The integration of CAD and GIS projects through a DXF format takes advantage of the attributes of both technologies.

AutoCAD is an accessorial desktop cartography software widely used in project cartography for its easy manipulation and data edit ability. GIS is a powerful tool of using computers to make dimensional with advantage of display, analysis, output and management of geographical data. The data of the two systems is not compatible and they need to be transformed for data sharing and application. This paper points out the difference of AutoCAD and GIS data, analyzes some common problems during the data transforming process and introduced the experimental study which takes example for transforming the CAD forestry map of Buyunshan country, Dalian city to ArcView geographical information system. The objective of this paper was trying to find an effective way for the transformation from CAD graphics files to geographical information system.

As staff and budgets shrink and environmental requirements grow, facilities managers face a critical need for more timely access to geographic-based information to achieve regulatory compliance. An integrated Geographic Information System (GIS) can successfully satisfy this need for a large municipality. But for managers at smaller facilities, a full-function GIS often exceeds what is needed and affordable. Such managers can derive similar benefits with minimal staff, budget, and equipment investments by developing a microcomputerbased system, using CAD/CAM software as a mapping package linked with third-party database management software. This paper describes how a military installation in Hawai'i successfully built such a system using AutoCAD and dBase III+.

3D city models are important in urban planning for sustainable development. Usually and traditionally, urban planners design the future layout of the towns by drawing the maps, using GIS or CAD packages. 3D city models based on these maps are quite effective in understanding what if the plan is realized. However, creating 3D city models is labor intensive, using a 3D modeling software such as 3ds Max or SketchUp. In order to automate laborious steps, we are proposing a GIS and CG integrated system for automatically generating 3D building models with general shaped roofs by straight skeleton computation, based on general shaped building polygons (building footprints) on digital maps.

GIS is a spatial information system combining geography, cartography, remote sensing and computer science, which is widely used in different fields. As a computer system, GIS can input, store, query, analyze and display geographic data. In the 1980s, GIS gradually began to be applied in the field of urban planning. This kind of digital technology meets people's requirement for regional geographic environment visualization. At the same time, the development of the network has also provided help for the popularization and development of this technology, making the dissemination and sharing of data possible. Nowadays, as an important technology, GIS has been widely used in all fields of urban planning and has gradually become an indispensable part. Arcgis as GIS platform building and applications will be treated as big data analysis and data visualization as an important part of planning, implementation of the software data correlation of traditional urban planning, break traditional design and drawing mode, through the spatial analysis function to generate new information, make decisions and solve problems efficiently, and make a prediction to the development of future city. Through the introduction of Arcgis data organization structure, CAD data loading, mapping and modeling under Arcgis platform and Arcgis spatial analysis function, this paper discusses how to use Arcgis platform to realize the application of urban planning and design.

With the drive to continually reduce the cost of connecting new Coal Seam Gas (CSG) wells, Worley developed new methodologies using commercial off-the-shelf software, and custom development, to automate engineering and improve operational efficiency for pipelines and gathering systems. One of the recent developments is an automated and data-driven approach to produce Gathering Network Diagrams (GNDs), an alternative to conventional Piping & Instrumentation Diagrams (P&IDs). On a recent project, Worley implemented a GND workflow capable of showing ~40 wells per A3 deliverable in conformance with intelligent drafting standards. This reduced ~2000 as-built P&IDs to ~200 GNDs (and associated standard details) with a significant improvement in quality and usability. Prior to generation, a site walkdown was conducted to address mismatches between as-built P&IDs, Geographic Information System (GIS) and what was actually installed at site. Our client now has a suite of GNDs that match the installed asset and are produced from the corporate GIS database, essentially their Digital Twin. Worley then focused on integrating flow assurance software with GIS allowing data-driven execution of future design packages to be incorporated into the master GNDs. We successfully integrated with PipeSIM and GAP, allowing for seamless transfer of hydraulic inputs from GIS to the modelling software. Engineers can now synchronise the confirmed process design back to GIS without producing red-lined and/or CAD-drafted deliverables which greatly improves efficiency and reduces human error. This paper demonstrates how digital automation can be applied to the CSG industry to significantly reduce cost and schedule whilst enabling data-driven operational efficiencies.

In fact, Computer Aided Design (CAD) offers powerful design tools to produce digital large scale topographic mapping that is considered the backbone for construction projects, urban planning and landscape architecture. Nowadays local agencies in small communities and developing countries are facing some difficulties in map to map transformation and handling discrepancies between the physical reality and represented spatial data due to the need for implementing high cost systems such as GIS and the experienced staff required. Therefore, the require for providing a low-cost tool based on the most common CAD system is very important to guarantee a quality and positional accuracy of features. The main aim of this study is to describe a mathematical relationship to fulfil the coordinate conversion between two different grid references applying two-dimensional conformal polynomial models built on control points and a least squares fitting algorithm. In addition, the automation of this model was performed in the Microsoft Visual Studio environment to calculate polynomial coefficients and convert the positional property of entities in AutoCAD by developing spatial CAD tool. To evaluate the proposed approach the extracted coordinates of check points from the interpolation surface are compared with the known ones.

Economically successful available scheduling tools such as Primavera and Microsoft Project fail to provide information about the geographical aspects of a construction project. A methodology using geographical information systems (GIS) is developed to represent the geographical aspects of the construction progress graphically by accompanying and linking it with the construction schedule. The spatial or geographical aspects are illustrated by the 3D model developed in AutoCAD and the construction schedule is generated via MS Excel sheets and linking it to ArcVIEW. Spatial and scheduling information are linked together into the GIS environment (ArcGIS) With a GIS, we can identify and analyze the land features, climate, boundaries, population, resources, and many other things about places that interest you. In the past, you needed to use paper maps, globes, and a variety of hard-copy data sources to perform these analyses. The main purpose of the research is to discover a simple and perceptive way of assigning the essential project information from a constructional CAD model to scheduling software and streamlining sequencing and organizing project activities. In achieving this goal, one of the most exhausting and time-consuming steps in producing a construction project schedule will be removed. By the end of this project, we will be able to understand the GIS system, and how to visualize it while scheduling the project and its uses.

Ancient architectures have always been of great interest to a variety of studies. In this analysis, the distribution of ancient architectures in Taizhou, Zhejiang Province is investigated. In each area of the distribution, the characteristic of the ancient architectures are recorded, such as story number, building materials, construction time, etc. The various types of information are then input into a GIS (Geographic Information System) database, which also contains some typical images of the ancient architectures. Some of the data are from GoogleEarth or archived CAD (Computer Aided Design) files. Consequently, the distribution and characteristic of ancient architectures are analyzed consulting the GIS map and attribute table. Although the ancient architectures are similar in Taizhou, Zhejiang Province, there exist some notable differences. The commonness and differences would be significative for the preservation and planning for ancient architectures.

The design and installation of solar panels on the roofs of urban buildings often require consideration of the specific spatial conditions that affect their efficiency. The primary purpose of this work is to develop a procedure for designing and optimizing photovoltaic installations using geomatics methods and specific tools of GIS and CAD systems. The roof of the historic building A2, which is a part of the Poznań University of Technology campus, was selected as the tested object. Solar radiation modelling and determination of suitability zones were performed using SEBE (Solar Energy on Building Envelopes) in QGIS. Possible options for the placement of photovoltaic modules on the roof were simulated with CAD technique in the web-based HelioScope software. The results of the simulation show that the current roof area can generate electrical power of 99.9 MWh/year. The proposed methodology is universal for photovoltaic installations on built-up roofs and can be applied to other buildings and, consequently, the results obtained can be used to improve the content of the solar data urban geoportal.

Abstract. In this work, we propose a dynamic, flexible and interactive urban digital terrain platform (DTP) with spatial data and query processing capabilities of Geographic Information Systems (GIS), multimedia database functionality and graphical modeling infrastructure. A new data element, called Geo-Node, which stores image, spatial data and 3-D CAD objects is developed using an efficient data structure. The system effectively handles data transfer of Geo-Nodes between main memory and secondary storage with an optimized Directional Replacement Policy (DRP) based buffer management scheme. Polyhedron structures are used in Digital Surface Modeling (DSM) and smoothing process is performed by interpolation. The experimental results show that our framework achieves high performance and works effectively with urban scenes independent from the amount of spatial data and image size. The proposed platform may contribute to the development of various applications such as Web GIS systems based on 3-D graphics standards (e.g. X3-D and VRML) and services which integrate multi-dimensional spatial information and satellite/aerial imagery.

The paper describes a case study based on surveying at the archaeological mission at Tell-el Retaba (Egypt). Advantages of the tool (e.g. significant optimization of surveying work) and its limits (demands on keeping conventions for the points’ names coding) are discussed here as well. Possibilities of future development are suggested (e.g. generalization of points’ names coding or more complex attribute table creation).

Full textAbstract:
Few examples of enterprise geographic information systems (GISs) implementation are as important and illustrative as the use of GIS to support the four stages of emergency management (EM). The full range of data required to support the four stages of EM are much greater, then any one department can be responsible for by itself. Only with an enterprise-wide GIS perspective can the full range of required data elements be made available to the emergency manager. Most critically, to keep these data sets accurate and up to date, the emergency manager must rely on other agencies and functions to keep all the data current. Without other assistance, the data requirements for the EM team will be quickly overwhelming. Waugh and Hy describe emergency events as either intentional (terrorism) or unintentional (weather/earthquake). The focus of this analysis is primarily on unintentional events, yet examples show that the four stages of EM are applicable with either type of event. Enterprise GIS has not been discussed much lately, but it is absolutely critical to solving the information needs of the contemporary emergency manager. Enterprise GIS means that many of the key data sets needed to support the four stages of EM are readily available, in a consistent manner and are always up to date. An enterprise perspective also means that GIS data are compatible with surrounding areas and GIS products are consistent with local, state, and federal information needs/requirements. The “common operating picture” we hear so much about in today’s EM world. Most importantly, an enterprise GIS perspective means that all data and systems work together or can “talk” to each other. Easily sharing data by address or by parcel means that the information/knowledge content can grow quickly and ad-hoc data requirements or events can be handled quickly and reliably. GIS is no longer a system or even just an architecture—it literally is a way of thinking. It is so exciting to implement GIS capabilities only to see that they can be used in ways not originally intended or described. This is analogous to the EM problem of having data/maps collected for the last emergency and not the current one! This means that the GIS staff get involved and more fully understand the in-depth system requirements of each application/data set. By putting these requirements together, in an enterprise-wide perspective, we can begin to see how a school inventory needed for drug free zones (for the district attorney’s office) is also useful as a possible shelter/feeding/inoculation site inventory for EM. A cell tower inventory for address assignments (for E-911/CAD) may also prove useful to the assessment professionals who see income potentials in silos, flag poles and steeples, often on tax-exempt properties like churches or municipal water tanks. A gasoline station inventory from Health’s Weights and Measures is immediately applicable to EM’s requirements for a better understanding of possible gasoline rationing actions/scenarios. Another way of looking at enterprise GIS and its support of EM would be to always think about the other stages of EM as this particular data/map or application is being collected, designed, or implemented. Perhaps just including another data element or two could support other later (or earlier) stages of EM? The GIS data can provide the continuity that EM needs to handle an incident through the four stages.

Currently it is a critical situation when every year due to aggressive external factors thousands of listed buildings are under threat of destruction around the world. In many ways, the state of affairs is due to the lack of effective integrated management of listed buildings. Lack of integrated tool for operating of different data, which determines the structural integrity of listed buildings and condition of environment, has led to the fact that most of the regional and municipal authorities are not able to handle the diversity of information. To address these problems specialist of Department of City Planning and Community Development of Rostov State University of Civil Engineering developed the methodology and information-analytical support system of listed buildings’ preservation. This support is able to analyze different types of data and to use different IT technologies such as CAD systems, GIS-technologies and databases. Information technologies in management of listed buildings can help municipalities with a limited budget to get the most out of existing services as these are the technologies that help different departments to work more closely with each other.

Optimal planning of utility supply station location is an integral part of infrastructural projects. In general, this is a multi-objective optimization process by considering engineering, financial and geographical constraints. A shift from conventional 2D-CAD, manual quantification and design application-based approach to Building Information Modelling (BIM)-Geographic Information System (GIS) integrated approach is found to be suitable for minimizing optimal planning time, cost and increasing automation. In this paper, an Autodesk Revit add-in tool is proposed aimed at integrating BIM and GIS for Genetic Algorithm (GA) based utility supply station location optimization and to assess the possibilities of this integration. From the case study it is observed that up to 90% of cost saving can be accomplished by this proposed approach. It is found that compared to the traditional multi-software approach with manual data transfer, this integration can be utilized for multi-stage optimization and is suitable for automating heterogenous data integration with increased accuracy. The platform in which the add-in tool is developed for the utility network can be at either BIM or GIS and this selection is influenced by the availability and ease of data retrieval from the respective semantic information system and the level of automation that is to be accomplished. Standardised BIM-based modelling combined with concepts like artificial intelligence and image processing techniques can be promising for attaining desired results in industrial applications.

Full textAbstract:
Analytical methods that are currently used to determine transformer substation placement in the process of planning the development of low-voltage distribution networks are based on calculating the lengths of future power lines by Euclidean distance, or methods for comparing several alternative placement options taking into account the routes of power lines. Assumptions made in this case lead to the fact that for the selected location of the substation, the total cost of the power lines connected to it may exceed the possible minimum. The use of modern GIS technologies allows simulating the routes of laying power lines on the map bypassing the existing obstacles or finding the cheapest routes for crossing them. These opportunities can be used to improve the quality of designing urban distribution networks through minimizing the construction cost of new power lines. However, the methods of organizing the solution to such a design problem have not yet found practical applications. The aim of the work is to develop a practical method of designing the placement of power substations in the GIS environment and its verification using real data. The paper uses methods of spatial modeling in the GIS environment, including methods of overlay, finding optimal paths on graphs and power grid inventory, as well as discrete optimization methods. A method of computer-aided design of transformer substation placement in urban distribution low-voltage networks is proposed and implemented as a GIS software module, which allows finding the optimal options of the placement cost at the stages of network scheme selection. The paper presents the results of the method analysis based on studying the design of the power grid scheme of Ivanovo city quarters as an example. The results confirm the possibility of using GIS to improve the quality of decisions on the choice of placement of low voltage distribution substations when designing urban electrical networks and can be used in the electrical networks CAD.

Full textAbstract:
Barrow Island is a Class 'A' Nature Reserve off the northwest coast of Western Australia. West Australian Petroleum Pty Limited (WAPET) has conducted oil exploration and production activities on the island for the past 30 years. The Company recently completed an extensive 3D seismic program over the northern two thirds of the island. Two years of government liaison were required to obtain the necessary environmental approvals for the project to proceed. WAPET and its seismic contractor utilised some of the latest Computer Aided Design (CAD) Geographic Information System (GIS) and Global Positioning System (GPS) technology to assist in planning the project and combined this with extensive on-the-ground work to ensure the highest level of environmental protection in a very important ecosystem. The project illustrated the benefits of early planning, ongoing communication, use of new technology, a multi-disciplinary approach and continuous improvement in environmental management.

The paper deals with cartographical and geoinformatical evaluation of Czech urban plans. The disparity between plan and map terms and how this disparity is perceived by cartographers and city planners is discussed. The processing of urban plans with GIS and CAD software is depicted and two groups of the most common mistakes made by processors of urban plans are demonstrated. The first group includes cartographical mistakes, the second one technical mistakes generated during digital processing. Explanation of the potential impact of these imperfections on urban plan users is emphasized and the ways how to eliminate these mistakes are delineated. The recent standards for urban planning in Czechia and their future changes are described together with web visualisation of urban plans.

The science of cartography should provide a historical mission, that is navigation, and also meet modern agendas including significantly expanding opportunities for BIM technologies, integrating functions of GIS and CAD systems. In this regard, cartography should be considered a fundamental basis for modern trends while creating digital twins of spatial objects. The practical part of the provided experiments included data collecting aimed at Moscow Saints Petersburg railway infrastructure, the calculation of optimal parameters of the oblique Mercator projection in the Hotine version for the given object, and the construction of a 3D railway track model. This research investigated the principles of unique cartographic projections, strictly focused on the certain functioning objects. The research can helps many users and designers of digital twins of spatial objects pay their attention to the applied cartography specifics concerning these issues and also take into account the recommendations while creating Building Information Modelling (BIM) and Infrastructure Information Modelling (IIM) as well.

Considering various fields of applications for building surveying and various demands, geometry representation of a building is the most crucial aspect of a building survey. The interiors of the buildings need to be described along with the relative locations of the rooms, corridors, doors and exits in many kinds of emergency response, such as fire, bombs, smoke, and pollution. Topological representation is a challenging task within the Geography Information Science (GIS) environment, as the data structures required to express these relationships are particularly difficult to develop. Even within the Computer Aided Design (CAD) community, the structures for expressing the relationships between adjacent building parts are complex and often incomplete. In this paper, an integration of 3D topological indoor building modeling in Dual Half Edge (DHE) data structure and outdoor navigation network from Open Street Map (OSM) is presented.

Full textAbstract:
One of the most well-known and largest early medieval necropoles in Western Europe lies near the small town of Lauchheim in Baden-Württemberg, South West Germany. Totaling round 1400 inhumations dating from 5th – 7th Century AD, it was completely excavated between 1986 – 1996. Due to the high frequency of finds and the fragility of some of the bone material, much use was made of block lifting. Some blocks remain unopened till today. The good state of preservation and the juxtaposition of the necropolis with a contemporary settlement, which was also extensively excavated, set the stage for an extensive social-historical analysis of a local early medieval com-munity over two centuries. Analysis of the grave good and anthropological appraisal have been combined and structured in a specially designed Database containing over 30,000 individual en-tries. A GIS Map of the site, arduously piped from the original hand drawings via vectorization software and CAD into Open Source GIS, allows for perspicuous visualization of any combination of anthropological data and/or finds and contributes greatly to the understanding of the development of the necropolis. Since 2008 the Lauchheim Project has been supported by the German Research Council, allowing innovative conservation and documentation methods including complete anthropological examination, 3D computer tomography of the unopened blocks (with sometimes surprising results) and the extensive examination of organic material and textiles.

Abstract. A city is a geographic entity and should be efficiently analysed and optimised through the use of geo-spatial technology. The certification for a city to be ‘Smart’ is measured on the basis of the liveable index, adequacy of water supply, assured supply of electricity, proper sanitation and solid waste management, efficient urban mobility, public transport, affordable housing, robust information technology connectivity, transparent and good governance, safety and security of citizens, modernised health and education infrastructure and citizen participation which will lead to sustainable development. Smart Cities require a perfect balancing of modernisation of city infrastructure and leveraging technology. Smart cities require Geo-smart mapping and visualization capabilities with applications for protecting groundwater resources, locating schools and health centres, locating garbage dumps and toilets, designing bus routes. The indigenously developed integrated platform of GIS, Image Processing, Photogrammetry and CAD, called IGiS has been leveraged by Scanpoint Geomatics Limited, Ahmedabad (SGL), India for implementing the Enterprise GIS for 7 smart cities in India. A centralised geo spatial database with a standard data model compliant set of maps/layers has been created for each city. The spatial layers are derived from 30cm resolution satellite data. Point data (locational information) is generated using DGPS surveys. The city assets are geographically mapped at a scale of 1:2000 and organised in a spatial database. Inputs required for operations and maintenance of every utility/facility are geo tagged and stored in the database. Web & Mobile GIS applications & Citizen portal are developed using the indigenous platform. Integration with other e-governance applications and spatial layer requirements of the Integrated Command and Control Centre are supported through RestAPI & OGC compliant web services. SGL’s Mobile GIS framework named Qpad comes handy for spatial data verification. IoT devices are used to gain insights for real-time handling of critical situations or emergencies. Having laid the foundation for driving smart cities in terms of the spatial database at a scale of 1:2000, the stage is set to look forward to the results. Plugging revenue leakages, better traffic management, information at a click during peak of the Corona pandemic, effective usage of open spaces and barren areas, planning the utility requirements by the corporation to accommodate for the urban explosion is the kind of harvest that is anticipated with abated breath. This paper demonstrates the suitability and capability of the indigenously developed common platform for image processing and GIS (IGiS Enterprise Suite) in building Smart City Applications and quantifying the results.

An archive is a collection of materials intended to be kept safe for the long term. Those materials are gathered by some responsible agency, but they were created originally by others. They were made in the forms and with the methods chosen by their creators. That is, an archive contains materials that have been created by others, that have been formed and informed by the judgements of others and that are intensely idiosyncratic. An archive is not simply a collection of facts or ideas or objects; it is a collection of other peoples’ individual or collected facts and ideas and objects. As a result, the contents of an archive are disparate in the extreme, from books to diaries to maps to photographs. A digital archive is at least as chaotic as any other, probably more so. Its contents may include text files, data-base files, images, CAD files, GIs files and more.

Abstract. In this work, we propose a dynamic, flexible and interactive urban digital terrain platform with spatial data and query processing capabilities of geographic information systems, multimedia database functionality and graphical modeling infrastructure. A new data element, called Geo-Node, which stores image, spatial data and 3-D CAD objects is developed using an efficient data structure. The system effectively handles data transfer of Geo-Nodes between main memory and secondary storage with an optimized directional replacement policy (DRP) based buffer management scheme. Polyhedron structures are used in digital surface modeling and smoothing process is performed by interpolation. The experimental results show that our framework achieves high performance and works effectively with urban scenes independent from the amount of spatial data and image size. The proposed platform may contribute to the development of various applications such as Web GIS systems based on 3-D graphics standards (e.g., X3-D and VRML) and services which integrate multi-dimensional spatial information and satellite/aerial imagery.

Monitoring the progress of building’s construction is critical in construction management. However, measuring the building construction’s progress are still manual, time consuming, error prone, and impose tedious process of analysis leading to delays, additional costings and effort. The main goal of this research is to develop a methodology for building construction progress monitoring based on 3D as-built model of the building from unmanned aerial system (UAS) images, 4D as-planned model (with construction schedule integrated) and, GIS analysis. Monitoring was done by capturing videos of the building with a camera-equipped UAS. Still images were extracted, filtered, bundle-adjusted, and 3D as-built model was generated using open source photogrammetric software. The as-planned model was generated from digitized CAD drawings using GIS. The 3D as-built model was aligned with the 4D as-planned model of building formed from extrusion of building elements, and integration of the construction’s planned schedule. The construction progress is visualized via color-coding the building elements in the 3D model. The developed methodology was conducted and applied from the data obtained from an actual construction site. Accuracy in detecting ‘built’ or ‘not built’ building elements ranges from 82&ndash;84&thinsp;% and precision of 50&ndash;72&thinsp;%. Quantified progress in terms of the number of building elements are 21.31% (November 2016), 26.84&thinsp;% (January 2017) and 44.19&thinsp;% (March 2017). The results can be used as an input for progress monitoring performance of construction projects and improving related decision-making process.

Full textAbstract:
Various micro-scale models for comparing alternative design concepts have been developed in recent decades. The objective of this study is to provide an overview of current user-friendly micro-climate models. In the results, a vast majority of models identified were excluded from the review because the models were not micro-scale, lacking a user-interface, or were not available. In total, eight models met the seven-point inclusion criteria. These models were ADMS Temperature and Humidity model, advanced SkyHelios model, ANSYS FLUENT, ENVI-met, RayMan, SOLWEIG, TownScope, and UMEP. These models differ in their complexity and their widespread use in the scientific community, ranging from very few to thousands of citations. Most of these models simulate air temperature, global radiation, and mean radiant temperature, which helps to evaluate outdoor thermal comfort in cities. All of these models offer a linkage to CAD or GIS software and user support systems at various levels, which facilitates a smooth integration to planning and design. We detected that all models have been evaluated against observations. A wider model comparison, however, has only been performed for fewer models. With this review, we aim to support the finding of a reliable tool, which is fit for the specific purpose.

Abstract In the paper we indicate the way to allow the coexistence of multiple structures that are mutually supportive, but not mutually exclusive. It allows less organized users to classify entities according to their suitable structure, whilst leaving the possibility for specialised users to classify these entities into related field classification systems or domain ontologies, in mutually beneficial cooperation. Replacing the reductionist enumerative structure with multiplicative categorization should bring organizational and terminological flexibility that will allow future updates without disrupting the existing categorization. It allows one to use parallel hierarchical branches of categories according to aspects and classify the entity into several branches at the same time. It should allow users the freedom to create their own structures without disrupting the structures of other user groups. Such structures could coexist happily side by side. The aim is to indicate the model of an independent data organization system in building design in a multilingual environment, connected through diverse CAD, GIS, BIM, CAFM applications, ECM, CDE, emails, databases and file systems.

Abstract In today's organization of data in civil engineering there remains ambiguity, diversity of terminology and consequent lack of clarity. The daily reality is to work with hybrid data sources in a variety of software programs. In CAD programs it is possible to import and convert elements from GIS, but they will be classified only into layers. Or, attach external references from CAD files in BIM, but there still remains the problem of finding your way around the confusing list of layers, and their abbreviations. Also broadly used filesystems as place for store and organise data on disk into files (entities) and hierarchical structure of folders (categories) is limited by reductionist categorization approach. Another problem shows with absence of multilingual approach. The limits are in the methods of data organization, and so only partially portable. Therefore, if there is a common denominator to all problems, it is the absence of a unifying organizational environment. In current computer applications used in civil engineering, methods of data classification are implemented that do not allow multiplicative or faceted categorization and thus inevitably create an antagonistic environment with any previous or future classification system. Unfortunately, even if a software tool implements a modern multiplicative categorization or domain ontology, it will not significantly solve the overall situation, because it will still not be possible to use such a method of categorization in other applications. Therefore, if there should exist a solution that would significantly facilitate cooperation and orientation in the data, it must inevitably work independently, across diverse software applications, with the ability to link the functions of the application with such a separate categorization system.

Abstract. Although the use of location-based data (location coupled with semantic information) within Geographical Information Systems (GIS) and from Earth Observation (e.g. satellite) sources has been long established for decision makers, this has only recently been reflected in the construction sector with a more recent move from Computer Aided Design (CAD) to Building Information Modelling. BIM has opened up an additional source of valuable location-based data, with particular focus on the architecture, structural and engineering detail of both buildings and infrastructure projects. As with most if not all location data, while BIM can be used on its own, major benefits are to be derived from integration with other data sources. When this is done with GIS, the result is known as GeoBIM and although there are some similarities between the two, challenges to integration are both technical and non technical, in particular the need for clear case studies to motivate both developers and senior management. There are synergies to be gained from a multi-national, coordinated approach when addressing these challenges, where participants can benefit from each-others’ experience and where the needs of users and the National Mapping and Cadastral Agency (NMCA) perspective underpin the research. This paper summarises final outcomes and findings of the EuroSDR GeoBIM research project, which was set up to provide the required multi-national, user-centric collaborative framework, which had as its overall aim the development of best practice guidelines for GeoBIM, and due to its situation within EuroSDR has an NMCA focus. The paper updates information with regard to GeoBIM projects and maturity in the participant countries, and provides an overview of the two case studies developed.

There are many algorithms based on computation of intersection of lines, planes etc. Those algorithms are based on representation in the Euclidean space. Sometimes, very complex mathematical notations are used to express simple mathematical solutions. This paper presents solutions of some selected problems that can be easily solved by the projective space representation. Sometimes, if the principle of duality is used, quite surprising solutions can be found and new useful theorems can be generated as well. It will be shown that it is not necessary to solve linear system of equations to find the intersection of two lines in the case of E2 or the intersection of three planes in the case of E3. Plücker coordinates and principle of duality are used to derive an equation of a parametric line in E3 as an intersection of two planes. This new formulation avoids division operations and increases the robustness of computation. The presented approach for intersection computation is well suited especially for applications where robustness is required, e.g. large GIS/CAD/CAM systems etc.

This paper focuses on the presentation of a part of the main thematic data documenting the pathologies and the degradation problems of a contemporary mural painting, which was designed and carried out by the italian artist Giuseppe Capogrossi in 1954. This forgotten masterpiece is developed on the ceilings of the main double stairscase at the entrance of the Airone, an ex-cinema-theatre in Rome (Italy). In time, the original project was completely damaged and now the Airone cinema is abandoned since 1999; the decoration, strictly connected to the function of the original project, has been completely covered by synthetic coatings. The documentation of the observed pathologies and the original materials of the lower ceiling takes place during a restoration project in 2015&ndash;2016 and was accomplished by utilizing different technologies in order to facilitate the collecting of the main data within several graphic thematic tables. The challenge of this documentation was to create a contact point, and perhaps also a contamination, between the practices of CAD graphic documentation, restoration and GIS technology.

Это соответствует правилам информационного и математического обеспечения САПР создания пространственно-графических форм и тематических карт разного содержания. Вокруг распределенных БД разных ГИС образуется слой информационных взаимодействий различных проектов и пользователей. Отдельные БД соответствуют порталам - узлам связи пользовательской ГИС с глобальным информационным многообразием. ГИМ-технология реализуется на примере оперативного формирования специальной БД ГИС и построения статистических графиков развития пандемии нового коронавируса COVID-19 на национальном уровне. Процессы и графики моделируются в терминах теории надежности с описанием кривых функциями плотности вероятности распределения экстремальных событий, из которых оптимальной является функция Фреше распределения моментов времени выявления заболеваний у населения. Использование относительных показателей надежности минимизирует влияние ошибок данных, а их межстрановой анализ указывает на наличие постоянных коэффициентов уравнений, что позволяет применять эпидемиологическую модель в дальнейших исследованиях статистических рядов. Information and mathematical technology for collecting and primary processing of spatial data is organized in the form of geoinformation monitoring (GIM) according to metatheoretical principles of the structure of spatially distributed commutation fields - stratified (bundle) functionally connected spaces of constructive activity. This corresponds to the rules of information and mathematical support of CAD for creating spatial-graphic forms and thematic maps with different content. A layer of information interactions between different projects and users is formed around database of different distributed GIS. Individual database correspond to portals as nodes of communication of the user’s GIS with the global information diversity. The GIM technology is implemented on the example of the operational formation of a special GIS database and the construction of statistical graphs of the development of the novel coronavirus (COVID-19) pandemic at the national level. Processes and graphs are modeled in terms of reliability theory with the description of curves by probability density functions of the distribution of extreme events, of which the Frechet function of the time moments distribution for coronavirus disease detected cases in the population is optimal. The use of relative reliability indicators minimizes the impact of data errors, and their cross-country analysis indicates the presence of constant coefficients of the equations, which makes it possible to apply the epidemiological model in further studies of statistical data.

Full textAbstract:
Traditional inverse distance weighting (IDW) interpolation is a process employed to estimate unknown values based on neighborhoods in 2D space. Proposed in this study is an improved IDW interpolation method that uses 3D search neighborhoods for effective interpolation on vertically connected observation data, such as water level, depth, and altitude. Borehole data are the data collected by subsurface boring activities and exhibit heterogeneous spatial distribution as they are densely populated near civil engineering or construction sites. In addition, they are 3D spatial data that show different subsurface characteristics by depth. The subsurface characteristics observed as such are used as core data in spatial modeling in fields, such as geology modeling, estimation of groundwater table distribution, global warming assessment, and seismic liquefaction assessment, among others. Therefore, this study proposed a seismic liquefaction assessment and mapping workflow using an improved IDW application by combining geographic information system (GIS) (ArcGIS (Esri, Redlands, CA, USA)), NURBS-based 3D CAD system (Rhino/Grasshopper (Robert McNeel & Associates, Seattle, WA, USA)), and numerical analysis system (MATLAB (MathWorks, Natick, MA, USA)). The 3D neighborhood search was conducted by the B-rep-based 3D topology analysis, and the mapping was done under the 2.5D environment by combining the voxel layer, DEM, and aerial images. The experiment was performed by collecting data in Songpa-gu, Seoul, which has the highest population density among the OECD countries. The results of the experiment showed between 7 and 105 areas with liquefaction potentials according to the search distance and the method of the approach. Finally, this study improved users’ accessibility to interpolation results by producing a 3D web app that used REST API based on OGC I3S Standards. Such an approach can be applied effectively in spatial modeling that uses 3D observation data, and in the future, it can contribute to the expansion of 3D GIS application.

Full textAbstract:
This article proposes an original method of a coherent and simplified cartographic presentation of the interior of buildings called 2D+, which can be used in geoinformation applications that do not support an extensive three-dimensional visualisation or do not have access to a 3D model of the building. A simplified way of cartographic visualisation can be used primarily in indoor navigation systems and other location-based services (LBS) applications. It can also be useful in systems supporting facility management (FM) and various kinds of geographic information systems (GIS). On the one hand, it may increase an application’s efficiency; on the other, it may unify the method of visualisation in the absence of a building’s 3D model. Thanks to the proposed method, it is possible to achieve the same effect regardless of the data source used: Building Information Modelling (BIM), a Computer-aided Design (CAD) model, or traditional architectural and construction drawings. Such a solution may be part of a broader concept of a multi-scale presentation of buildings’ interiors. The article discusses the issues of visualising data and converting data to the appropriate coordinate system, as well as the properties of the application model of data.

Conventional shallow water bathymetric survey methods are time consuming, expensive, susceptible to human error, and often hazardous. An innovative end-to-end solution that improves water surveying by reduc ing these risks through the use of an unmanned bathymetric data collection system has been designed and built. This system combines a collection of pre- and post-processing routines with the capabilities of a purposebuilt unmanned surface vessel to measure and build accurate bathymetric datasets that are easy to integrate into any CAD or GIS database. Data collection involves the fusion of high-accuracy data from a single beam echosounder, GPS, and iner tial measurement unit (IMU) to generate sediment surface points at centimetre-level accuracy. Through use of an unmanned vessel, these surveys are repeatable without requiring any persons to be on or in the waterbody. This paper presents the results of a focused validation study conducted to illustrate that this platform gen er ates comparable data to a manual survey while greatly reducing survey time and improving safety. Results show a volumetric difference of 2.8% between the Kingfisher USV and manual survey data. Surveying duration was shorter at 42 minutes compared to 140 minutes. This survey was also reliably completed despite challenging environmental conditions.

The use of 3D information models within collaborative working environments and the practice of Building Information Modelling (BIM) are becoming more commonplace within infrastructure projects. Currently used predominantly during the design and construction phase, the use of BIM is capable in theory of providing the information at handover that will satisfy the Asset Information Requirements (AIRs) of the future Infrastructure Manager (IM). One particular challenge is establishing a link between existing construction-centric information and the asset-centric information needed for future operations. Crossrail, a project to build a new high-frequency railway underneath London, is handling many such challenges as they prepare to handover their digital information to the future operator, in particular the need to provide a two-way link between a federated 3D CAD model and an object-relational Asset Information Management System (AIMS). This paper focusses on the potential for improved Asset Management (AM) by integrating BIM and GIS systems and practices, and makes a preliminary report on how 3D spatial queries can be used to establish a two-way relational link between two information systems (3D geometry and asset lists), as well as the challenges being overcome to transform the data to be suitable for AM.

AbstractThe use of digital techniques is often applied today by archaeologists in the field to get quick and reliable 3D surveys for their research. 3D models and reconstructions are the focus for the use of these techniques. The aim of this paper is to present the methodology employed during the 2018 season, and its combination with that from 2016 on the private areas of the bishop’s residence of the Episcopal Palace in the ancient city of Side, Turkey. This paper will focus on the data acquisition process, accuracy of the survey, errors and solutions as well as the workflow-process of the data. The aim is to present a useful workflow to combine surveys at a maximum level of accuracy with already completed surveys. A Total Station (TS) survey, Global Positioning System (GPS) Real Time Kinetics (RTK) survey and Structure from Motion (SfM) are among the techniques used to compile the information later exported into a Computer Aided Design (CAD) and Geographic Information System (GIS) environment. Eventually, viable applications of the data created with such methods that help to formulate a new hypothesis for the ritual and non-ritual areas will be shown: plans, 3D models, digital elevation models (DEM) and orthophotos.

Road surface survey is critical for road engineers to determine the needs of maintenance and rehabilitation for both network and project level study. This paper reviews the road surface survey methods, including image based, photogrammetric and stereo-vision, and mobile mapping systems. The merits and demerits of each method are outlined. The goal of this study is to develop simple software for facilitating the generation of the necessary road surface and distresses maps using surveying data from different sources. The software output has compatibility with known CAD/GIS packages to widen its scope of applications. Methodologies, examples and demonstration related to the use of the developed software and laser scanning data in road mapping for a case study are described. The results showed the flexibilities of the developed software and the proposed method for generating the necessary maps and data for road distresses such as longitudinal cracks, transverse cracks, patch deterioration, potholes, and ravelling. However, the present work shows that using terrestrial laser scanning technologies for modelling the road surface has advantages such as surveying speed, big roads, highways and tunnels. Also it provides the safety for surveyors and the absence of a disruption to traffic. The developed software and methodology are suitable for universities, academic centres and are of great interest to small engineering firms for the generation of road surface maps.
