Expansion of Skydog Aircraft Model Control System by Remote and Autonomous Control by Android Application
Boček, Michal ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The thesis aims to design and implement an Android application with ability to control the autopilot of the Skydog aircraft model using the wireless telemetry. The application shall receive data from an aircraft model gathered from various installed sensors. These data shall be then processed and corresponding instructions for autopilot shall be sent back. When collision with terrain or obstacle is detected, the application shall send instructions to autopilot to avoid such collision. RRT algorithm is used to find collision-free flight trajectory. Database of known obstacles and digital terrain model are provided to application in formats XML and GeoTIFF respectively.

Surveying and documentation of part of route Cesta v Luzích (cadastral area Nuzířov)
Maňas, Jaroslav ; Vitásek, Josef (referee) ; Vondrák, Jiří (advisor)
Theme of Bachelor thesis is tacheometric survey of area that includes part of cycle path and contiguous Lubě stream with its joining into reference systems S-JTSK and Baltic Vertical Datum- After Adjustment. It was necessary to build up the survey net before survey works could even start. The net was created by GNSS method and polar method. Detailed survey was executed by a polar method as well. The outcome of these works is thematic map at a scale of 1:500 and also the experimental version of digital terrain model (DTM). Test of accuracy of the map was executed by checking profiles.
Terrain creation in the Revit program
Meluzín, Tomáš ; Volařík, Tomáš (referee) ; Berková, Alena (advisor)
This bachelor´s thesis deals with the creation of a digital terrain model in AutoDesk Revit software. It explores the three options for creating a digital terrain model offered by Revit. Terrain modeling based on contour lines, inputting elevation points directly in Revit, and modeling based on an imported text file with coordinates. The input data for the first mentioned option, contour lines, was created in AtlasDMT software. This process is also described in the thesis. The thesis is devided into two parts. The first part focuses on Digital terrain model issues and related data collection methods, and the second part provides a detailed procedure for creating a digital model in Revit. The outcome of this thesis is a digital terrain model of the surrounding area of the object of interest and a site plan of this area.
3D RECONSTRUCTION OF ABANDONED SETTLEMENTS OF THE CENTRAL POVLTAVÍ
Andrštová, Martina ; Štych, Přemysl (advisor) ; Jaroš, Jakub (referee)
3D reconstruction of abandoned settlements of the central Povltaví ABSTRACT This work deals with the use of Geoinformatic systems to create the three-dimensional model of an extinct landscape. The main subject of this bachelor work is the three-dimensional reconstruction of extinct municipalities in the central area of the Vltava River. The main task was to create digital terrain model of the original Vltava valley. The passage from Zvírotice to Svatojánské proudy has been chosen as the model territory. Two selected municipalities Zvírotice and Živohošť were thoroughly worked up. Many data sources were used in this work, such as historical photographs, historical aerial photographs or current orthophoto maps. Digital terrain models were created with the help of these datas and then the models were overlain with the orthophotos. 3D models of buildings and vegetation were put in the terrain models. Two periods were compared, 50th of the 20th century and present. Results of this work are fly-by animations and perspective scenes. The results will be used in newly built museum in Chotilsko town. Keywords: 3D reconstruction, DTM, land cover changes, orthophoto
Mapping of the Litavka catchment using GPS
Hojcsková, Daniela ; Matějíček, Luboš (advisor) ; Brůna, Josef (referee)
This thesis is aimed on the study of Global Positioning System (GPS) and its utilization possibilities in nature sciences such as ecology, hydrology, botany and the others. The main contribution of this work is the investigation of current possibilities of the most accurate data collection by using GPS and their subsequent processing in GIS with focus on small catchment. Other methods of terrain data collection are described and compared with GPS in this work, as well. Practical part of the thesis focuses on characteristics of the locality, technical equipment and data editing gained in terrain. The study locality is the Litavka catchment, which is situated in Brdy. The geographical ground data, were gained from ZABAGED and were completed with results of own measuring in terrain. The output of the thesis is the digital terrain model of upper stream of the Litavka River modified by interpolation. Key words: GPS, DTM, GIS, mapping, catchment, Litavka, interpolation
Design of Pravčická brána 3D model and its integration with 2.5D TIN terrain model
Brýdl, Ivo ; Brůha, Lukáš (advisor) ; Lysák, Jakub (referee)
The main goal of this thesis is to design integrated model containing a three-dimensional representation of Pravčická brána rock arch and 2.5D TIN model of surrounding terrain. Point cloud from airborne lidar measurements has to be classified into ground and non-ground features. The ground points are the basis of the TIN terrain representation. Second part of this thesis is focused on methods for reconstructing 3D surface from given points set retrieved with ground-based lidar measurement. The thesis describes the process of meshing point cloud with Poisson surface reconstruction. Finally, these two models are oriented and translated to real coordinates in order to form integrated hybrid model covering part of České Švýcarsko National Park.
3D reconstruction of landscape in abandoned villages of borderlands and military zones
Jelének, Jan ; Štych, Přemysl (advisor) ; Oršulák, Tomáš (referee)
3D reconstruction of landscape: A case study of extinct municipalities in Czech borderlands and military areas Abstract This work deals with theoretical and practical possibilities to use GIS to create three-dimensional model of landscape changes. The object of the work was the creation and visualization of three-dimensional model of extinct municipalities Padrť in a military area Brdy and Košťálkov in the borderlands. The work used many available data sources, such as historical aerial photographs, historical photos, current orthophotos or historical maps. These data and specialized software were used to create digital models of the selected area, including three-dimensional models of buildings and vegetation, with emphasis on historical closeness. Work was focused on three selected periods of history: 40th of the 18th century, 30th to 50th of the 20th century and present. The work resulted in fly-by animations and perspective scenes, which are compared with historical photographs. Historical models are also confronted with each other by a dynamic fading in fly-by animations.
Use of contemporary 3D geoinformation technologies for historical reconstructions of sites: case study Zahrádka u Ledče nad Sázavou
Berka, Rostislav ; Laštovička, Josef (advisor) ; Štych, Přemysl (referee)
Use of contemporary 3D geoinformation technologies for historical reconstructions of sites: case study Zahrádka u Ledče nad Sázavou Abstract This bachelor thesis deals with contemporary 3D GIS technologies and methods used for historical reconstructions, especially reconstructions of lost sites and objects. Thesis contains an overview of technologies, methods and softwares suitable for these purposes. Thesis is focused on quite unique single image-based modeling, which uses geometry of object in the image. There is also brief overview of visualisation 3D models on the internet and web mapping. Thesis introduces a prescription for creating 3D model of lost site. First, TIN is produced from contours of old maps and DMR 5G data using breaklines, which are generated automatically. SFM models of preserved objects and models of destroyed objects acquired through single image-based modeling with help of old archival images, are placed on DTM. The case study area is the lost town of Zahrádka u Ledče nad Sázavou. The results of this work are view scenes and interactive web map aplication for visualisation of 3D model. The accuracy of used single image-based modeling method is compared to the standard SFM technique. SFM had better accuracy. Keywords: 3D model, 3D GIS, single image-based modeling using geometric...
