Testing of the accuracy of the heights measured by GNSS
Stolárová, Ivana ; Volařík, Tomáš (referee) ; Kuruc, Michal (advisor)
The diploma thesis deals with a testing of the real coordinates accuracy measured in favorable and unfavorable conditions, which are determined by method GNSS RTK. The work explores the real accuracy and reliability of heights measurement with the signal noise and multipath interference occurring, caused by surrounding vegetation, buildings, power lines, and also the accuracy under optimal conditions while measuring in a meadow. Influence of day time, observation length, correction provider to internal and external precision is watched. It also examines the issues of initialization in these conditions. For this purpose was collected set of statistics containing 960 measurements on 30 points. During survey was used apparatus Trimble R4. GNSS measurements were statistically processed and evaluated and finally the results were compared with the results of Bc. Klára Kordasová, who measured the same tested points with identical methodology using apparatus from Leica company. Results of the thesis can be used in praxis.

Creation of thematic map in the Moravian Karst
Stolárová, Ivana ; Kalvodová, Petra (referee) ; Kalvoda, Petr (advisor)
Bachelor thesis deals with creation of thematic map in karst surface, specifically in the area of sagging Bílá voda brook to the cave Nová Rasovna. Location is situated in North – East part of the Moravian Karst. At the beginning it is necessary to create suitable surveying network, which was created by polygon two-side attached and two-side oriented. It was followed by tachometry survey of situation with generalization suitable to map scale 1:500 and 3th accuracy class and finally creation of contour lines. Survey of detail points of planimetry and altimetry parts was realized by the polar method and they were attached to system S-JTSK and Bpv. Graphic processing was realized in system Microstation. Thesis should be used as an accurate orientation in location and also for needs of administration of PLA Moravský kras.
