Der volle Inhalt der QuelleAerial photography with UAS is in comparison with traditional photogrammetry more efficient, cheaper and safer which has led to this technology being preferred by many performers. A time-consuming job that has been difficult to avoid is to establish signals at the ground that are used for georeferencing and evaluate the results. In 2018, the UAS manufacturer DJI presented its new quadcopter with integrated Real-Time Kinematic (RTK) module. This allows continuous and accurate positions delivered via Network RTK (NRTK) and the need of ground control points can be reduced. In this study, investigations of the position uncertainties in orthophotos produced using a DJI Phantom 4 RTK carried out where the aerial images were georeferenced with limited numbers or without ground control points. The position uncertainties were calculated and controlled according to the Swedish HMK – Ortofoto (Orthophoto) which is a document within the subject. When producing an orthophoto, a digital terrain model (DTM) or a digital surface model (DSM) is also required and the quality of this has a great impact on the result. Therefore, a part of the DSM used for orthophoto production for each set was checked and evaluated according to the Swedish technical specification, SIS-TS 21144:2016. The result of the study shows that an orthophoto can be produced without ground control points and at the same time meet the requirements for specified position uncertainty according to HMK standard level 3. The total position uncertainty was calculated to be 0,029 m, which is 5 mm higher compared to the orthophoto based on the traditional georeferencing method, i.e. with ground control points. The requirement for quality in height data was also met for orthophoto production even though a systematic effect in height occurred. This effect did not affect the plane coordinates in the orthophoto because of the low standard uncertainties in height. The result showed that if two ground control points were added at each end of the area, the systematic effects were minimized, and it was possible to produce a DSM that fulfils the requirements for accuracy class 1-3 according to SIS-TS 21144:2016.

Der volle Inhalt der QuelleThe technology of Unmanned Aerial Systems (UAS) has gained popularity as atool for mapping and modeling applications in recent years. This is mainly dueto the technological developments that have largely automated the process ofproducing digital elevation models (DEMs) and orthophotos. This study investigates the factors that effect the height uncertainty in anelevation model that is produced with data collected with a NRTK-UAS(Network Real-Time Kinematic UAS). We also evaluate two differentscenarios i.e. how the uncertainty is affected by using only NRTK-UAS andthe effect of adding ground control points (GCPs) to NRTK-UAS. It is alsoinvestigated how the flying height and using oblique images affect the DEMuncertainty. This will be assessed by comparing two flights i.e. by capturingnadiral and oblique images. The oblique images were captured at a 60° angle. The study was realised with help from the surveying engineer of Falunmunicipality, who maneuvered the UAS. The study area was around three anda half ha and consisted mainly of park. To be able to test differentgeoreferencing methods GCP:s were surveyed, as well as control profiles thatserved as a reference for investigating the uncertainty of the elevation model.There were totally 3 different flying methods tested: 100 m with nadiralorientation, 50 m with nadiral orientation and 50 m with oblige orientation. The acquired data was processed in the software Agisoft Metashape, where itwas georeferenced with different above-mentioned methods. To be able toexamine which impact GCP has on the uncertainty, five different sets withdifferent number of GCP were made with the photos captured from 100 mflying height. The RMS value varied from 0,060 m for NRTK+1 GCP whichhad the lowest RMS value to 0,068 m for NRTK+2 GCP which had the highest RMS value. We used the combination of NRTK-UAS and GCPs for testing the impact offlying height on the uncertainty. The flying heights 100 m and 50 m wascompared. A decrease of the uncertainty was observed when the flying heightwas 50 m instead of 100 m. Our results show that the RMS-value increased from 0,014 m to 0,017 musing nadiral and oblique images, respectively. The difference is too small tobe able to draw a conclusion. The results for the oblique images improvedwhen only hard surfaces such as asphalt, concrete etc. were observed.

Der volle Inhalt der QuelleThere are a few available studies purely focusing on the object heights significance on image overlap in UAV-photogrammetry. Therefore, it is interesting to examine how object heights, image overlaps, and altitudes affect each other and how they jointly affect data quality. The purpose is to examine how image overlap, and altitude affect the quality of orthophotos and digital elevation models. And also examine how object heights affect image overlap. The study area was selected with the criterion of including a high rise building. Therefore, the study area was Inre hamn in Karlstad City covering Löfbergsskrapan, a 42 m high coffee roasting house. The study refers to UAVs restricted according to rules set by Transportstyrelsen (TSFS 2017:110). The objective was to present useful reference tables for companies and individuals working with UAV-data. Data was collected on the altitudes; 120 m and 90 m with an image overlap of; 60/60 %, 80/80 %, and 90/90 %. Elevation values was collected with Satlab GNSS. Results showed that using an image overlap of 60/60 % for both altitudes was not viable in an area covering an object of 42 m high. The image overlap should be at least ≥80/80 % to cover objects of 42 m high. The objective was also to examine how image overlap differ when an object is below ground level. Results showed that image overlap increases when an object or surface differ 42 m from ground level and decreases if the object is above ground level. The conclusion suggests that in order to include objects of 42 m high in an area the image overlap should be at least 80/80 % for both altitudes (120 m and 90 m). With those settings the ground resolution in orthophotos and digital elevations models should be 2-3 cm. It was also estimated that the image overlap may alter from settings anywhere between 10-50 % when ground level is 42 m below the point of departure of the UAV.

Der volle Inhalt der QuelleThe geodetic reference systems, and the related frames, constitute the basic structure that allows to compare geometric representations of the earth acquired by different surveys. The last century has seen a continuous evolution in the definition of geodetic frames, mainly due to new needs, and possibilities, introduced by the space geodesy techniques. Are changed the scale of the problem, the precision of the measurements and the required accuracies, and also the approaches and definitions. The requirement of a global reference system has imposed the definition of dynamic frames, which follow the evolution of the earth's crust as a whole, so the need for introducing a time coordinate in addition to usual geometric coordinates. The dynamic nature of the Earth involves variations in time of coordinates, when expressed in the global reference system, too quick to be handled in mapping applications on a continental / national scale. So it was necessary the definition of other reference systems, linked to the tectonic plates. Thus, fundamental are the transformation parameters needed to switch from regional systems to global systems, and vice versa. In this thesis the topic of the monitoring of dynamic reference frames has been addressed, in particular the Italian Rete Dinamica Nazionale. The matter of the high residual ETRS velocities that characterize the Italian peninsula has been addressed, and a new ad hoc reference system was defined. The calculation technique of Precise Point Positioning has been investigated, both from the geodetic point of view, addressing the strategies to align the coordinates in the global system, than from the point of view of technical surveys. Finally, the geodetic networks of the Emilia-Romagna Region were analyzed, evaluating their importance in the age of GNSS.

Der volle Inhalt der QuelleThe issue related to the power of externalization of the Assembly's President represents a problematic aspect of constitutional law due to its different implications and the numerous intersections between constitutional and legislative fact as well, and also doctrine and praxis configuring, so, it is an environment of research made by an undoubtful relevance and actuality of the internal constitutionalist debate. It's clear that the analysis about this statement needs the assuming of a point of view which won't can be just strictly technical -juridical but also and necessarily will have to relate with the elements of the political-constitutional praxis.

Der volle Inhalt der QuelleThis PhD thesis dealt with the evaluation of different sodium bentonite samples. The planned activities were aimed to understand the interactions between bentonites and different molecular weight proteins naturally contained in white wines. Further investigations were related to the impact of the clays on varietal and fermentative aroma compounds of musts and/or wines. Results underscore the key role exerted by the “matrix factors”: bentonite dose and typology and wine style have to be carefully considered before planning a fining treatment.
