Fotogrammetric analyses of aerial pictures of mountain landscape and generation of DEM
Hynštová, Marie ; Stuchlík, Evžen (advisor) ; Matějíček, Luboš (referee)
This thesis describes the stereo photogrammetric method used for digitalization of terrain elevation data of choosen area and the applications of digital elevation model (DEM). The main part of the thesis consists of DEM generation methodology, including stereo photogrammetric evaluation of aerial pictures, quality control of evaluating process, DEM creation and revision. DEM was created in software Edras Imagine 8.6. The thesis results in detailed description of DEM creation in the high mountain terrain selected in the High Tatra Mountains. Grid DEM of cell size 1x1 meter is attached. Key words: mountain lakes and catchments, photogrammetry, aerial pictures, DEM

Influence of catchment characteristics of high-mountain lakes in the Tatra Mountains on water chemistry
Hynštová, Marie ; Stuchlík, Evžen (advisor) ; Matějíček, Luboš (referee)
The presented thesis deals with catchments of the alpine lakes in the High Tatra Mountains. The lakes were subject of a long-term monitoring to detect changes of chemical and biotic composition of lake water induced by acid atmospheric deposition and by its decline. The studied processes required a quantitative approach to describe the characteristics of the catchments. The definition of new catchment parameters or the refining estimated parameters was not allowed without current technical and computing equipment because of the complexity of mountainous terrain. The morphological parameters for 26 catchments were obtained by analysis of the created digital elevation model (DEM) using tools of geographic information system (GIS, software ESRI ArcGIS 10.2). The land cover was detected by Google aerial map (2014). The links between chemical composition (NO3⁻, Σ(Ca2+ +Mg2+ )) and catchment properties based on the specified or refined catchment parameters (slope, portion of an area with a slope <26 ř in the catchment, proportion of different land cover types to the real catchment area) were analysed between the years 1993 and 2012 (respectively 2006). New morphological parameters were derived for the defined catchments. The catchments on the northern and the southern slope were distinguished by...
