GNSS deformation measurement in the Sněžník Network
Sobek, Josef ; Weigel, Josef (referee) ; Švábenský, Otakar (advisor)
This thesis deals with a processing and evaluation of GNSS data measured during the years 2001 - 2012 in geodynamical network Sněžník. The aim of the thesis is a detection of possible horizontal and vertical displacements of points in this network. The thesis also deals with comparison of results determined by only GPS and both GPS and GLONASS measurements. Graphic interpretation of displacements’ evolution during the whole monitored period is one of the results of this thesis.

Gravity measurements at Tetčice polygon
Bitalová, Katarína ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
This master's thesis deals with measurements of highs and gravity of points polygon located in village Tetčice, through which is crossing a eastern fault of Boskovice furrow. With repeated measurement should be proved effect to high levels of groundwater. Repeated measurements are realized in the range 2 stages. In thesis is in detail described calculation complete Bouguer gravity anomaly and their quantitative interpretation. From the gravimetric of dates is created map of complete Bouguer gravity anomaly and interpretative profile through Boskovice furrow. Interpretative profile has localized fault, whose tectonic activity belong to possible factors level movement in the village. Level measurements meets the requirement of precise levelling. The results of the measurements are compared and discussed with the previous stages of the research.

Vertical Displacement Measurements at Brno Zábrdovice Church
Bocková, Lenka ; Kratochvíl, Radim (referee) ; Weigel, Josef (advisor)
The diploma thesis deals with measuring height new stage of the church network in Brno Zabrdovice. Measuring by using method of precise leveling be going on with previous stage began in 2002, in order to detect vertical displacement. Processing include calculation and adjust of the heights, compare with fundamental and previous stage, interpretation and graphical form of vertical displacement. The thesis includes measuring and processing angular deflection of church towers.

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.

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.
