Map of geodynamic phenomena in Lower Tatra area
Jackulíková, Denisa ; Bartoněk, Dalibor (referee) ; Pospíšil, Lubomil (advisor)
This investigative thesis provides an overview of the structural and kinematic formation of the Low Tatras in Slovakia. Numerous geological and geomorphological data from previous studies of the researched area were available. These were processed in a graphical user interface ArcMap to produce the Geodynamic map of Low Tatras at a scale of 1:200 000. By illustrating geodetic, geomorphologic, geophysical and other similar data on this map, it was possible to undertake a detailed analysis of the area and allow an assessment of the overall tectonic activity. This revealed two regions with higher than normal stress levels and therefore an associated increase in the risk of future seismic activity.

GPS measurements at the Tetčice polygon
Darmopilová, Jana ; Švábenský, Otakar (referee) ; Pospíšil, Lubomil (advisor)
This thesis deals with periodical measurements at the Tetčice polygon to confirm geological activity caused by geological shift that pass through the center of the village. This work was focused on the third phase of measurement by long static GNSS observation in summer 2013 to monitor horizontal shifts on both edges of Boskovice furrow. Points are stabilized on pillars with forced centring. Part of the thesis is summary of present results, the differences between the various stages and graphical representations of shifts. The theoretical part deals with the geological conditions in the area and description of GNSS technology.

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.

GIS ANALYSIS IN BUILDING INFORMATION MODELS
Černý, Martin ; Kubíček,, Petr (referee) ; Vyhnálek,, Rudolf (referee) ; Bartoněk, Dalibor (referee) ; Pospíšil, Lubomil (advisor)
This dissertation thesis are concerned about the Geographic Information Systems (GIS) and spatial analyses inside of the Building Information Models (BIM). BIM and GIS are compared from different points of view like data organization, geometry types and modelling paradigms. Results of this comparisons are applied in the first case study where BIM data in IFC format are converted to the SHP format usable for spatial analyses in GIS. The results of the case study are evaluated and new approach for spatial analyses in BIM models is proposed based on the results. The new proposed approach is based on the semantic relations existing in the BIM models. Thesis are concluded with the future development which is in line with authors actual focus.

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.

Permanent GNSS Networks and Their Use in Geodynamic Monitoring of the Bohemian Massif
Pospíšil, Lubomil ; Švábenský, Otakar
The paper deals with the problematics of permanent GNSS stations and networks in terms of their use for geodynamic research. General aspects and characteristics of the establishment and operation of permanent stations are stated. Some purpose-built geodynamic networks related to important regional projects are described. Finally, attached are two examples of geodynamic research using permanent GNSS networks in the Czech Republic. The first example concerns the survey of indications of horizontal movement tendencies concerning the territory of the Bohemian Massif and its relations to the surrounding structures. The second example concerns a more detailed geological and geodynamic research of the fault systems of the Blanice Graben.

Repeated GPS measurements at polygon Tetčice
Petrlík, Karel ; Švábenský, Otakar (referee) ; Pospíšil, Lubomil (advisor)
This diploma thesis deals with epoch GNSS measurement by static method at Tetčice polygon. The main purpose is to confirm the geological activity of the Earth's surface on the territory of the village, caused by a tectonic fault. As part of the thesis, the fourth phase of observation was carried out in June 2016 to detect horizontal shifts on four concrete pillars with depth stabilization and forced centering equipment. Results are velocity vector maps obtained by processing the measured data from all the measurement phases that have been performed so far. The thesis also contains the theoretical basis of geological conditions in the area and a description of technology of global navigation satellite systems.

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.
