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.

Map of the Vypustek Cave Surroundings - southern part
Stískalová, Alena ; Fišer, Zdeněk (referee) ; Weigel, Josef (advisor)
This thesis is about mapping of the southern surroundings of the area caves Výpustek in the ratio scale 1:500 with the schematic mapping of the subterranean part of the cave. The theoretical part is devoted to the history of this cave and creating maps. The practical part contains calculations, creation of maps and representation of vertical cuts. The outcome is the sketch of the position and diagrammatical sketch of the existed locality and vertical cuts.

Map of the Vypustek Cave Surroundings - northern part
Sánthová, Zuzana ; Kratochvíl, Radim (referee) ; Weigel, Josef (advisor)
The aim of this thesis is to create map of cave Výpustek surrounding enviroment. It is going to be complementary map documentation to existing map documentation made by the other students of VUT Brno. These documentations will be joined together and create one relief covering terain above the cave. The work began with building our own traverse and measuring detailed points. The result is topographical and hypsographical determination of the locality expressed numerically and topographically too. Another task was to measure and represent some profiles of main halls and passages of the cave. Intention is to connect underground space with the surface. Surveying network of points built previously inside the cave was used for measurements.

Map of the Dratenická Cave Surroundings in Moravian Karst
Hanuš, Vojtěch ; Švábenský, Otakar (referee) ; Weigel, Josef (advisor)
The aims of my diploma thesis are the design of a map of Drátenická cave surroundings in the Moravian Karst in the 1:500 scale with details utilizable by speleologists and the examination of a map of 1945 depicting the region of Drátenická cave. The thesis includes an elaboration of the theoretical foundations relevant for the fulfillment of the aims and the descriptions of the geodetic and processing procedures. The outcome of the thesis is the planimetric and altimetric survey, a new digital map of the region and the final examination of planimetric and altimetric components of the map of 1945.

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.

Deformation Surveying of Railway Track
Štrba, Peter ; Weigel, Josef (referee) ; Švábenský, Otakar (advisor)
The aim of this diploma thesis is to specify the displacement and deformations of the railway tracks axis on bridge structures in cities of Zábřeh na Moravě and Břeclav. The bridge structures covered have great dilatation distances, therefore it is necessary to monitor the movements of the railway tracks depending on climatic conditions. GPS methods have been used throughout the whole measurement and data processing. The result includes also a comparison of GPS and conventional methods. The result of the thesis is a detection of proven displacements. One of the goals of the thesis is the comparison of the displacements and the accuracy using the method chosen by author of the thesis and using classical geodetic methods.

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.
