Mapping of the Litavka catchment using GPS
Hojcsková, Daniela ; Matějíček, Luboš (advisor) ; Brůna, Josef (referee)
This thesis is aimed on the study of Global Positioning System (GPS) and its utilization possibilities in nature sciences such as ecology, hydrology, botany and the others. The main contribution of this work is the investigation of current possibilities of the most accurate data collection by using GPS and their subsequent processing in GIS with focus on small catchment. Other methods of terrain data collection are described and compared with GPS in this work, as well. Practical part of the thesis focuses on characteristics of the locality, technical equipment and data editing gained in terrain. The study locality is the Litavka catchment, which is situated in Brdy. The geographical ground data, were gained from ZABAGED and were completed with results of own measuring in terrain. The output of the thesis is the digital terrain model of upper stream of the Litavka River modified by interpolation. Key words: GPS, DTM, GIS, mapping, catchment, Litavka, interpolation

Mapping Of Litavka Basin Using GIS
Barešová, Magdalena ; Matějíček, Luboš (advisor) ; Benešová, Libuše (referee)
The purpose of this work is the use of the Geographic Information System (GIS) for a model evaluation of a selected area of Litavka basin. The theoretical section focuses on the description of GIS, GPS and selected GIS projects (ZABAGED, National inventory of contaminated sites, ArcČR500). The practical area focuses on processing the data. There were several thematic layers created including: the digital terrain model (DTM), thematic layer on the slope, aspect to the north, and a layer of aerial photographs containing current and historical status. The project was completed with a thematic layer of test sampling profiles. The practical part included a chemical analysis of water samples from Litavka carried out in Laboratory of water protection of the Institute for Environmental Studies. The purpose was to demonstrate the influence of rural agglomeration on water quality changes. The quality grade of the flow was determined by appointed indicators according to the Czech Technical Standard CSN 75 7221 Water quality. All data was entered into the GIS project. Key words Geographical Information System, mapping, Digital Terrain Model, Global Positioning System, Litavka, river basin/watershed, quality of surface water
