Volumetric and Evaporation Analysis of the Landštejn reservoir
Hánová, Karolína ; Bednář, Martin (referee) ; Marton, Daniel (advisor)
This bachelor thesis focuses on the volumetric analysis and estimation of evaporation from the water surface of Landštejn reservoir. The main objective is to determine new bathymetric curves of the reservoir based on the most recent bathymetric survey of the bottom and then to estimate the amount of evaporated water for a selected period. To achieve these objectives, ArcGIS tools will be used to create a digital terrain model that will allow accurate calculation of the bathymetric curves through volumetric analysis. The amount of evaporation will be determined using selected empirical formulas and simple balance analysis, taking into account the standard ČSN 75 2405 concerning the water management design of reservoirs and comparison with data from the Czech Hydrometeorological Institute. The practical part of the work includes the creation and evaluation of a digital terrain model of the Landštejn reservoir and subsequent estimation of evaporation based on average temperatures and other meteorological data. The results show new bathygraphic curves and provide accurate estimates of the volume of water evaporated from the reservoir over the specified period. This work contributes to a better understanding of the hydrological processes in the Landstejn reservoir area and provides important input for more effective water management planning and management.

Data capture for creation of DTM
Ondráček, Daniel ; Šváb,, Tomáš (referee) ; Kalvoda, Petr (advisor)
This thesis deals with the the capture of data for digital terrain model. The specified location was measured in cooperation with the student Tomáš Kobližek. Surveying networks were auxiliary survey points that were measured by GNSS. Measurements were connected to the system Uniform Trigonometric Cadastral Network and Baltic height system after the settlement. Detailed points were measured by tacheometry and comply with third accuracy class and have been tested by CSN 01 3410. The main result of this thesis is special map at scale of 1:500.

River regulation and designing flood protection
Úlehla, Jiří ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This thesis focuses on assessing the capacity of the river channel Becvy in the urban area of Prerov and design of flood protection for the city. Flood protection was designed in two variants. In the first variant dealt with recess bottom of the river. The second variant included a proposal of flood protection wall combined with a mobile barriers. The results are summarized in the synoptic maps.

Data capture for creation of DTM
Kobližek, Tomáš ; Vondrák,, Jiří (referee) ; Kalvoda, Petr (advisor)
The subject of this thesis was to collect data for digital terrain model in the western part of the valley Kombutského stream between the villages Kotvrdovice and Jedovnice. It was built a network of auxiliary measuring points of which were measured specified territory by using tacheometry method. Then were calculated coordinates and height of measurement points. It was tested accuracy of control-points. From the measured data was drawn thematical map with scale 1 : 500. The final data were serve for puposes of subject GE14 Field Training II.

IMPROVEMENT OF DIGITAL MODEL BY LASER SCANNING METHODS
Tyagur, Nataliya ; Václav, Šafář (referee) ; Hana, Staňková (referee) ; Bartoněk, Dalibor (referee) ; Hanzl, Vlastimil (advisor)
The doctoral thesis deals with mobile laser scanning and data processing. Mobile laser scanning was carried out in the Moravian Karst in Suchy zleb and Pusty zleb at various seasons. Further scanning was carried out at the Training Forest Enterprise Masaryk Forest Křtiny. The Riegl VMX-450 scanner was used to collect 3D data. The data files were processed in the OPALS software. For the extraction of ground and non-ground points from the laser cloud, a combination of hierarchical interpolation and robust filtering was used. Subsequently, the terrain points were used to model digital terrain models with grids 0.05 x 0.05 m, 0.25 x 0.25 m, 1 x 1 m. Furthermore, digital models from Moravian Karst were compared with the Digital relief model of the Czech Republic 4G and reference points. Digital models from Masaryk Forest Křtiny were compared with photogrammetric and terrestrial data. The high accuracy of the derived DTMs is about 0.10 m. The high quality of the derived DTM can be used to monitor and analyze field changes and morphological structures.

A Set of Web Tools for Geo-Location System
Bečka, Petr ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
The main goal of the thesis is to develop a set of web tools to visualize results and exploit functionality of geo-location system LOCATE. Obtained informations could be showen in web map and digital terrain model. For interaction with user is prepared interface to upload photos. Furthermore was developed a method, witch allows to customize appearance and functionality of visualization means.
