Development and testing of device for absolute GNSS antenna calibration
Komárek, Josef ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The purpose of this diploma thesis is testing motion of the device for GNSS antenna calibration according to added weight to the device’s transom. First part of this thesis is devoted to introduction into GNSS antenna calibration problematics. The thesis deals further with development of the software used to process photogrammetric images that have been taken during testing measurement. The rest of the thesis is focused to process and evaluate the measurement. The result will be implemented into observation model used during calibration measurement. The period, during the device is still, will be corrected according to the result that has been obtained from the measurement.

Creation of software support to device for absolute GNSS antenna calibration
Galata, Marek ; Kuruc, Michal (referee) ; Kratochvíl, Radim (advisor)
The diploma thesis deals with creation of software support for the robotic device used for absolute GNSS antenna calibration, which is developed by Institute of Geodesy at Faculty of Civil Engineering, Brno University of Technology. In the beginning of this thesis, there is in general discussed issue of absolute GNSS antenna calibration. Then the text continues by description of calibration device itself together with summary of testing performed so far. Next sections are focused on its main content. There is mentioned testing calibration process, followed by all of every single steps, which leads the procedure towards gaining calibration parameters for removing errors arising due to instability of antenna´s phase center position.

Documentation of the church in Čučice village
Súkeníková, Terézia ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The aim of this thesis is the documentation of the church of James the Greater in the South Moravian village Čučice. It is complete drawings of the structure, consisting of the topographic situation around the church, floor plans, vertical sections and views on the facade. Text part contents writing about working activities. It also discusses the historical and cultural characteristics of the church as immovable monument, the description of the preparatory work, a way of building surveying networks and methods of measurement. Finally, it highlights the processing of measured values in the computing and graphics phases. Use of this thesis and its evaluation is given in the final chapter. Graphic documentation, along with sketches, notebooks, calculation protocols, lists of coordinates, and testing the accuracy are in the annex section.

Documentation of Skalní zámek passage in Býčí skála cave - southern part
Kubíčková, Alena ; Hanzl, Vlastimil (referee) ; Kratochvíl, Radim (advisor)
This bachelor thesis deals with speleological mapping of a part of the cave system Býčí skála in the Moravian Karst. The part that has been mapped is called Skalní zámek. For the purpose of this work documentation was processed for the southern part of the Skalní zámek. The existing graphic materials of the interest site were searched for and described. For processing purposes, available numerical data were also found, which were compared with the new measurement during processing. The polygon of Skalní zámek was measured by mining suspension compasses. For detailed measurements, a combination of the modified DistoX2 - laser distance range-finder and TopoDroid - software application per the appropriate tablet, was used. The results of the measurements were processed in an a free and open-source cave surveying software - Therion. In this program a ground plan of the Skalní zámek, a longitudinal section of the main hallway and a longitudinal section of the branching hallway was prepared. At the end of this work the symbol lists used by TopoDroid and Therion were compared with the official UIS symbol list

Documentation of Skalní zámek passage in Býčí skála cave - northern part
Langar, Tomáš ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
My bachelor thesis deals with speological mapping parts of cave system Býčí skála - Skalní zámek. Detailed measurements of plan view map are carried out with electronic method –through combination of measuring equipment DistaX2 and software application TopoDroid per the appropriate tablet. The resulting map is formed in the program Therion. The course of my bachelor thesis involves handling of apparatus and the instruction how to measure then process the data. The introductory part is devoted to the localization and extent of the thesis. The instructions of used surveying and software device are described in the subsequent parts. The final section is related to comparisons of mining suspension compasses.

Thematical map creation in locality V zrcadlech - northern part
Matušková, Klára ; Jurčík, Josef (referee) ; Kratochvíl, Radim (advisor)
The purpose of this bachelor´s thesis was a tacheometric measuring of a historical mining site in the Olomučany cadastre. A survey net was built in the area, using the GNSS technology and a traverse oriented on both ends. Detailed points have been determined by tacheometry. The result of the thesis is a large scale thematical map made in the CAD system with the emphasis on hypsography. The map should be used as a comparison to the historical mining map.

Thematical map of carst surface - Jedovnický brook spring
Netolický, Lukáš ; Machotka,, Radovan (referee) ; Kratochvíl, Radim (advisor)
This bachelor thesis deal with creating thematical map of karst surface near spring of Jedovnicky brook. This location is in the middle of Moravian Karst. The thesis is focused on creation suitable surveying network, which was created by polygon two-side attached and oriented. Requirements for this are listed here. Surveying of individual points was realized by polar methode. The content is further description of the resulting errors in the measurements and their removal. There is also discussed creating thematic maps in CAD software. For creating thematic maps was used software Microstation developed by Bently. Work should provide opportunities for accurate orientation in the location and the possibility of better protection.
