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.
Twenty Years of Operation of the TUBO Station at EPN
Bureš, Jiří ; Kostelecký, Jakub ; Švábenský, Otakar ; Weigel, Josef
In September 2001, the permanent GNSS station TUBO, which is located on the building of the Faculty of Civil Engineering of the Brno University of Technology, was connected to the European EUREF Permanent Network (EPN). The paper recalls the establishment of this station and its twenty years of operation and use of their data not only in the EPN network.
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.
The Using of GNSS Permanent Networks for Height Determination
Kuruc, Michal ; Sokol,, Štefan (referee) ; Kostelecký,, Jan (referee) ; Vatrt, Viliam (referee) ; Weigel, Josef (advisor)
This Thesis deals with the evaluation of height accuracy of GNSS point positioning. Many experimental measurements aimed on GNSS and heights issues was realised within this work. The ellipsoidal heights were measured together with the orthometric heights and then the local Quasigeoid model was created. The network of height points was built to realisation of proposed measurements on the territory of the city Brno. The model of Quasigeoid from experimental measurement was compared with any other models of Quasigeoid and with local astronomical model. The partial aim of this Thesis is the proposal of methodology of height determination by GNSS technology and levelling measurement together. We can determine or verify the orthometric heights by using GNSS measurement and this methodology.
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.
Determination of astronomical vertical deflections by field observations
Petrová, Kateřina ; Weigel, Josef (referee) ; Machotka, Radovan (advisor)
This thesis deals with use of the measuring system MAAS-1 for direct determination of vertical deviations at the points specified field. The main input data are geographical and astronomical coordinates of points. The aim of this thesis is to complete the processing of data measured in the locality.
Map of geodynamic phenomena in the Slanské vrchy Mts., and surrounding.
Lazoríková, Monika ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
The aim of the diploma thesis has been evaluation of available geodetic, geomorphological, geological and geophysical data and other possible map data, which are related to the motion and geodynamic properties in this part of Western Carpathians. The purpose has been also to evaluate possible kinematic relations and design appropriate areas for further GNSS monitoring. Especially Slanské vrchy area is located in the zone where there are no supporting GNSS points, despite the area is situated on the main tectonic breaks of eastern Slovakia. The results and all supporting materials have been processed in the GIS program and summarized in the basic geodynamic map of Slanské vrchy and the surroundings.
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.
Analysis of selected variations of the gravity due to the mass dynamics
Volařík, Tomáš ; Lederer,, Martin (referee) ; Vatrt, Viliam (referee) ; Mojzeš,, Marcel (referee) ; Weigel, Josef (advisor)
This dissertation is focused on a study of selected environmental effects influencing terrestrial gravity observations. Global geopotential models were used to compute quantities of the disturbing gravity field and its variations during time period. Furthermore, analyses of an atmospherical and hydrological effects on the gravity observations were provided. The computation was realized at the station Pecný, however the concept was proved and compared with data from station Strasbourg. Consequently, the results were discussed with respect to quasigeoid modelling established from gravity and astrogeodetic measurements. The result and recommendations for future research are exposed.
