Repeated GPS measurements at Tetčice polygon and its interpretation
Dvořák, Jiří ; Josef, Weigel (referee) ; Pospíšil, Lubomil (advisor)
This thesis deals with monitoring shifts in the vicinity of the village Tetčice. The site is located at the interface of geomorphological units. Monitor the area is done in stages and methods of using GPS and precise leveling. Points tested are expected movements in places the earth's crust, which are stabilized on the pillars in order to avoid possible negative effects. The work builds on results from previous measurements.

The measurement of the levelling network in a part of Brno
Sotolářová, Tereza ; Švábenský,, Otakar (referee) ; Weigel, Josef (advisor)
The measurement of the levelling network in a part of Brno The theoretical part of this study deals with the theory of heights, marking, stabilization of benchmarks and the history of Area of benchmarks in Brno. The practical part of this study is devoted to the levelling network, the method of the accurate levelling, the implementation of the corrections and the calculations of elevation difference, followed by evaluation degrees of accuracy of vertical distance. The results of the study were used for the project Specific research „Development of new methods in Geodesy measuring“, surveying with GPS and astronomical measuring.

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.

Horizontal and vertical positioning of survey net in laboratory B150
Hubáček, Josef ; Soukup, František (referee) ; Machotka, Radovan (advisor)
This bachelor thesis deals with the determination of the horizontal coordinates and heights of the survey control points in the B150 and B151 laboratories at the Faculty of Civil Engineering of the Brno University of Technology. Position coordinates are determined in the local coordinate system. The heights are connected to the Czech State Leveling Network and will be reported in the Baltic Vertical Datum - After Adjustment. The thesis is divided into chapters according to the individual stages of processing. The output of this bachelor thesis are a list of calculated coordinates and heights of the determined points and their overview.

Testing of the digital levelling instrument DiNi 22 and possibilities of its applications.
SEVERA, Tomáš
The aim of this diploma work was to test, to judge the accuracy and possibilities of applications of the digital level Trimble DiNi 22. It is a precise digital compensatory nivelating appliance, whitch together with a code invare rod answers the requirements for nivelation measuring with 0,7mm/km exactness of both - way nivelation. The exactness of measuring is always influenced by the conditions when the measuring is carried out. Atmospheric conditions infuence the measurement of all geodetic instruments and that is why the major part of this diploma work is dedicated to verifying the influence of atmospheric conditions on the accuracy of the digital level DiNi 22 measuring. For this purpose from September 06 to February 07 were repeatedly measured in different weather conditions separate points of different heights of the nivelation level line Mg 02 České Budějovice - Hluboká n. Vltavou line, which is a part of the nivelation net of IV. line.

Completion of height point field at the university campus CULS in Prague
Votava, Tomáš ; Loula, Jiří (advisor) ; Radim, Radim (referee)
The aim of this work was to build and extension of height point field within the
Czech University of Life Sciences nearby Faculty of Enviromental Sciences and the
Faculty of Forestry. The main objective is to achieve a certain accuracy of height
designated points, so that points can be established to another height measurement.
Another goal was to use these points for teaching lessons of geodesy.
To achieve the above objectives was used precise leveling, which was conducted
by levelin machine Zeiss NI 007.
First, it was necessary to stabilize points of height point field . Point are stabilized
in the solid material into concrete. It was drilled a hole into concrete, then into hole
was impregnated a special glue, after that a nail was set into the hole. Further points
which were used in original height networks are stabilized into the tarmac and into the
holes between the paving. All information about the point can be found in positioning
data.
The theoretical part is focused on the individual chapters, which deal with
everything you need to know for the completion of this project. Gradually there are
explained each chapters which making it clear why, what and how in this work was
carried out. Describes the height systems, types of stabilizations a signaling points.
The most important chapter is chapter about leveling, which analyze the measurement
principles of leveling. For this work is the most important method of precise leveling.
The practical part is focused on workflow of measuring the point network,
principles of writing into notebooks and calculations. In which are evaluated the results
and the accompanying outputs usable for further work with the points.
