Býčí skála cave documentation - part Mořské oko
Ulčík, Vojtěch ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The bachelor thesis deals with documentation of the part of cave system Býčí skála, namely of the passages Kaňony and Mořské oko in the form of a ground plan, extended longitudinal section and cross sections in the scale of 1:250. The work contains a description of the location where the work took place. It also deals with the process of creating, specifically reconnaissance, measuring the creating a surveying network, detailed mapping and producing the resulting map in the JTSK coordinate system and the Bpv vertical system. A speleological measurement method using the Disto X2 instrument and producing a measurement sketch on a tablet in the Topodroid program were used for the measurement.

Metric survey documentation of the main palace of Veveří Castle
Hirš, Bořivoj ; Kratochvíl, Radim (referee) ; Machotka, Radovan (advisor)
The aim of thesis was a production of blueprints of part of the 3rd floor of the main palace of Veveří castle. The survey was accomplished by the means of laser scanning and was followed up by the point cloud-based production of 2D drawings. It consists of the layout, cross sections, facade views in a scale of 1:50. These CAD drawings will be used for reconstruction of the 3rd floor of the building. The thesis consists of theoretical part further divided to the location presentation, survey methods used description and specifics of the heritage objects documentation. Then the practical part follows with processing and production of data in various software description.

Creation of a purpose map of the castle courtyard by the laser scanning method
Kučeravý, Peter ; Kratochvíl, Radim (referee) ; Machotka, Radovan (advisor)
This diploma thesis is dealing with creation of thematical map of castle courtyard of the Veveří castle using the method of laser scanning. The thesis describes the construction of a survey net which is important for measuring control points and then scanning of the area using the scanner FARO Focus 3D. The thesis contains a description of the method of laser scanning and point cloud processing in Trimble RealWorks software. Furthermore, this thesis deals with the accuracy of the point cloud and compares the laser scanning method with the typical tachymetric method according to time duration.

Cave maps and their symbols in publications Speleo and Speleofórum
Benešová, Karolína ; Kratochvíl, Radim (referee) ; Weigel, Josef (advisor)
The aim of this bachelor's thesis was to tackle the problem of map symbols used in maps of caves, cave systems and similar naturally created landforms. Two publications dealing with this issue were analyzed, namely the anthology Speleo and Speleofórum. For the Speleo magazine, it was 74 issues published between 1990–2019 and for the Speleofórum magazine 23 issues published in the years 1989–2019. In total, more than 1,000 maps and their map symbols were recorded. I total it was 264 and 340 symbols for the Speleo anthology and the Speleoforum respectively. Subsequently, the symbols were sorted into categories and digitalized. Only a fraction of the maps included a legend, and therefore the meaning of used symbols had to be identified in the text the respective article. Maps with key have become more common in the last five years, thanks to more affordable digital technologies such as Therion, which automatically provides a unified legend.

Testing of Precise Point Positioning Method
Nosek, Jakub ; Kratochvíl, Radim (referee) ; Machotka, Radovan (advisor)
This diploma thesis deals with the Precise Point Positioning (PPP) method in various variants. The thesis describes the theoretical foundations of the PPP method and the most important systematic errors that affect accuracy. The accuracy of the PPP method was evaluated using data from the permanent GNSS station CADM, which is part of the AdMaS research center. Data of the period 2018 – 2019 were processed. The results of combinations of different GNSS and the results of different observation periods were compared. Finally, the accuracy was verified at 299 IGS GNSS stations.

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.

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 Kaňony passage in Býčí skála cave - central part
Pribišová, Romana ; Vondrák, Jiří (referee) ; Kratochvíl, Radim (advisor)
This bachelor thesis deals with detailed mapping of part of the Býčí skála cave, namely, the central part of the Kaňony passage. The aim of this bachelor thesis is to create in the scale of the 1:250 ground plan with cross sections and extended longitudinal section of the given area The survey network was measured by polygonal traverse. For detailed measurements, we used the TopoDroid aplication tablet and modified Disto for a sketch creation. The next postprocessing was performed in the Groma and Microstation programs.
