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 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.

30 Years ff Geodynamic Research in the Territory of Northern Moravia
Švábenský, Otakar ; Pospíšil, Lubomil ; Weigel, Josef
As part of the investigation of the geodynamics phenomena, the deployment of GNSS technology, which enables effective determination of the kinematic tendencies of the upper layer of the earth's lithosphere, represents an important contribution. The Institute of Geodesy of BUT in Brno, as the first university institute in the Czech Republic, could practically use this technology since 1992, and one of the first activities was involvement in geodynamic research on a national and international scale. It is significant that it was just during this period that a local research geodynamic network covering the Czech and Polish parts of the Králický Sněžník massif was built. It was the first project of this kind in the territory of Moravia, and our institute had the opportunity to actively participate in this project. Today, at the commemoration of the 30th anniversary of the establishment of the Sněžník network, we can state its significant contribution to our scientific research and teaching activities. Since then, our activities in the field of GNSS geodynamic applications have expanded to the entire territory of Moravia, and later to the Czech Republic. A significant factor was the establishment of close 19 http://dx.doi.org/10.13164/seminargnss.2023.18 contacts with experts in other geoscience fields (geology, geomorphology, geotectonics, seismics, etc.), which made it possible to apply and present our results in a broader context of mutual cooperation. It has been confirmed that it is important to confront and integrate the results of geodetic measurements with all the relevant geoscientific knowledge that is currently available. This paper mainly deals with two topics. The first is a 30-year measurement period in the Sněžník network. The second is a description of our other activities focused on the investigation of geodynamic active areas of Moravia, especially its northern part. One of the significant results is the compilation of the initial kinematic model of the Moravian part of the Bohemian Massif and its continuous addition and refinement.

Calculation of local quasigeoid models from heterogeneous data
Kratochvíl, Richard ; Kostelecký,, Jakub (referee) ; Weigel, Josef (referee) ; Kratochvíl,, Vlastimil (referee) ; Machotka, Radovan (advisor)
The goal of this thesis was to evaluate whether it is possible to replace gravimetric data with topographic ones for calculating quasigeoid models using astrogeodetic levelling. Gravimetric data are not of sufficient quality in selected areas, hence their replacement can increase the accuracy of obtained models. The computational program PRVAK was created. It facilitates the calculation of the quasigeoid model by astrogeodetic levelling, the models can be calculated on a profile or in an area by least square adjustment of conditional observations from astrogeodetic deflections of the vertical or their combination with topographic ones. Furthermore, the Dolní Morava network was built, with astrogeodetic deflections of the vertical determined at 34 points. The data comparisons were tested at three localities, where quasigeoid models were calculated by astrogeodetic and astrotopographic levelling and compared with reference data. On the profile Velká Bíteš – Brno – Uherské Hradiště, the calculated models were compared with the gravimetric model calculated by Research Institute of Geodesy, Cartography and Topography. The standard deviation of the differences between the reference model and the models calculated in this work was reduced using astrotopographic levelling by approximately 38 % compared to astrogeodetic levelling. For area models of quasigeoid in the localities of Dolní Morava and Brno, it was possible to compare the internal accuracy of these models. When using astrotopographic levelling, values of standard deviation of height anomalies were reduced by 40 % in Dolní Morava locality and 25 % in Brno locality compared to astrogeodetic levelling. In both localities, the quasigeoid QGZÚ-2013 was chosen as a reference model for comparison of external accuracy. The contribution of astrogeodetic levelling to the improvement of external accuracy could not be demonstrated because the calculated models of quasigeoid have similar accuracy as the reference model.
