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.

Deformation Measurement of Roof Structure
Hubáček, David ; Švábenský, Otakar (referee) ; Bureš, Jiří (advisor)
The thesis deals with the evaluation of displacements and deformation of the large span wooden roof structure of the aquapark hall in Brno - Kohoutovice. The task of this work is to compare and verify the applicability of the laser scanning method for the evaluation of displacements and deformation. The comparison was performed with regard to the polar method with quantities measured by the total station. As part of the work, two-stage measurements were performed on the basis of which a comparison of both methods was performed. The data obtained by the polar method were processed using LSM, the data from laser scanning were processed in an Excel spreadsheet. A comparison of the two methods shows that we have achieved a similar level of accuracy with the laser scanning method when compared to the polar method. It is therefore possible to use the laser scanning method to measure displacements and deformation.

Geodetic Deformation Measurement of Roof Structures of Brno Aquapark
Chupáčová, Mária ; Švábenský, Otakar (referee) ; Bureš, Jiří (advisor)
Diploma thesis is focused on deformation meassurement of wooden roof structure of Brno Aquapark. Introductory part of the thesis is devoted to explanation of basic terms of civil constructions deformation meassurement and describes methods which are used in this field nowadays. Main part of this thesis deals with testing of meassuring equipment, describes meassured construction, meassuring method and data processing. Horizontal and vertical shifts of the roof structure are evaluated and graphically interpreted in comparison with the previous and fundamental epoch.

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.

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.

Aspects of GNSS Processing
Puchrik, Lukáš ; Kostelecký,, Jan (referee) ; Kratochvíl,, Vlastimil (referee) ; Hefty,, Ján (referee) ; Švábenský, Otakar (advisor)
The thesis deals with processing of epoch-wise GNSS measurements from local geodynamic network Sněžník. Its aim is to evaluate the geodynamics in the area of Králický Sněžník Massif and to assess the capabilities of epoch-wise GNSS measurements to detect the geodynamic movements. Within the thesis the comprehensive processing of all the GNSS measurements observed between years 1997 and 2011 is realized using the reprocessed products of first IGS reprocessing Repro1. Bernese GPS software version 5.0 is used for all the processing.

Deformation Measurement of the Roof Structure of a Sport Hall
Klinčík, Radoslav ; Švábenský, Otakar (referee) ; Bureš, Jiří (advisor)
Diploma thesis describes the measurement and evaluation of displacements and deformations of the wooden roof structure of the aquapark hall in Brno – Kohoutovice. Part of the work is devoted to the preparation and testing of used devices and tools. The main part of the work consists of performing one stage of measurement using the polar method and the laser scanning method. The polar method measurement is compared with the results of the polar method of the previous stage. The next part of the work deals with the comparison of the polar method and the laser scanning method measured in the last stage. The results achieved are interpreted in the final part of the work.

Deformation Surveying of Bridge Construction and Railway Track
Staněk, Boleslav ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
This diploma thesis deals with the phases measuring deformation of the bridge construction and railway superstructure on the bridge over the river Dyje in Breclav and its surroundings. The main goal was to determine the longitudinal displacements of the rail web and the bridge structure. The object of this thesis was also transverse displacements which have been caused mainly due to temperature changes. The introduction describes the location. The following section discusses the methodology terrestrial deformation measurements and calibrations selected surveying devices. Furthermore, there is stated the processing of measurements and the calculations. In conclusion, the thesis evaluates the longitudinal and transverse displacements, which are shown in the annexes.
