Accuracy testing of minor horizontal geodetic control determined by analytical aerotriangulation
Komárek, Josef ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
The purpose of this bachelor’s thesis is testing quality of minor horizontal geodetic control points in chosen area in South Bohemia. The control points have been established in the eighties of twentieth century during cadastrial mapping (large scale base map). Until now, those points were recorded in the 4th accuracy class. The geodetic control was remeasured with RTK technique, then deviations were calculated. These results were reviewed and evaluated whether the points match with the 4th accuracy class or even the 3rd accuracy class. The results were submitted to the local cadastral office in Jindřichův Hradec.

Sensor Calibration for Multispectral Data Fusion in Mobile Robotics
Kalvodová, Petra ; Hanzl, Vlastimil (referee) ; Mazal,, Jan (referee) ; Pospíšil,, Jiří (referee) ; Weigel, Josef (advisor)
Thesis deals with data fusion and calibration of sensory system of Orpheus-X3 robot and EnvMap mapping robot. These robots are parts of Cassandra robotic system that is used for exploration of hazardous or inaccessible areas. Corrections of measured distances are determined for used laser scanners Velodyne HDL-64, Velodyne HDL-32 and range camera SwissRanger SR4000. Software MultiSensCalib has been created and is described. This software is used for determination of intrinsic parameters of heterogeneous cameras of the sensory head and for determination of mutual position and orientation of these sensors. Algorithm for data fusion of CCD camera stereo pair, thermal imager stereo pair and range camera is proposed. Achieved calibration and data-fusion parameters are evaluated by several experiments.

Gravity measurements and repeated leveling at polygon Tetčice.
Zajíčková, Katarína ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
The object of this master´s thesis was levelling and weight measurement of the Tetčice polygon through which passes the fault of the Boskovice furrow. This is the 10th period of levelling and the second period of gravimetric measurement. The theoretical part describes the geological structure of the site, technology of high-precision levelling and technology of gravimetric measurement. The first part of the practical part deals with my own levelling measurement, the calculation of the resulting cambers and heights, consequential comparasion of the results with previous periods and, especially, with evaluation of the vertical movement tendecies. The second part of the practical part deals with my own gravimetric measurement, the calculation of the complete Bouguer gravity anomaly, creation map of complete Bouguer gravity anomaly and as well as evaluation of gravimetric measurement in relation to the results of the previous periods.

Deformation Surveying with GNSS technology
Míča, Vojtěch ; Weigel, Josef (referee) ; Švábenský, Otakar (advisor)
This bachelors thesis sets the task to measure, process and evluate data obtained through static GNSS method on a point in a network used to set out Královopolský tunnel, these measurements were obtained in the years 2002, 2004 and 2022. The other GNSS measurements were carried out on points in geodynamic network „Sněžník“ which were obtained between years 2012 and 2022. All of these measurements should be proccessed through Trimble Business Center. Based on the results it should reveal possible horizontal and vertical deformations in the direction to default points.

The measurement of the levelling network in a part of Brno
Sotolářová, Tereza ; Švábenský,, Otakar (referee) ; Weigel, Josef (advisor)
The measurement of the levelling network in a part of Brno The theoretical part of this study deals with the theory of heights, marking, stabilization of benchmarks and the history of Area of benchmarks in Brno. The practical part of this study is devoted to the levelling network, the method of the accurate levelling, the implementation of the corrections and the calculations of elevation difference, followed by evaluation degrees of accuracy of vertical distance. The results of the study were used for the project Specific research „Development of new methods in Geodesy measuring“, surveying with GPS and astronomical measuring.

Measuring of the Vertical gravity gradient at the locality TS-73 "Polom", Trutnov - Babí
Pešek, Michal ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
This master´s thesis deals with the determination of vertical gravity gradient in the shaft below the infantry bunker TS - 73 "Polom" located in village Babí. After performing position, elevation and gravity measurements detailed points, representing the two vertical profiles were calculated gravity, vertical gravity gradient, block densities ang gravity anomalies depending on the depth. Other outputs work as a topographic map and a map of full Bouguer anomalies for the wider area of the location and interpretive geologic profile.

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 - southern part
Chalupková, Klára ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
The intention of the bachelor’s thesis is geodetic survey of former mining sites V zrcadlech and creation thematic map of area of interest at a scale of 1:500 and according to ČSN 01 3410 Maps of large scales. Base and thematical maps. The first part of the thesis deals with the preparation and surveying of the site. The second part deals with the office work, both data processing, as well as creation of the thematic maps. There was built survey net of auxiliary survey points on the site, which was determined by polygonal traverse and three-tripod equipment system using a total station. Connection of the traverse was carried out on horizontal control and points measured using GNSS. Points of detailed survey were measured from auxiliary survey points. The computational work was made in software Groma v. 7.0 and the graphic work was made in software MicroStation PowerDraft V8i and Atlas DMT.
