Picek, Jan ; Lysák, Jakub (advisor) ; Dušánek, Petr (referee)
Visualization of digital terrain models made from airborne laser scanning data Abstract The aim of this study is to evaluate opportunities of 2D visualization of digital terrain models made from airborne laser scanning data. Each method is described in detail with other parameters and approach. The focus is put on methods which are useful for the topographic mapping (f. e. orienteering maps) and for cartographic visualization. All this methods are tested for different data and type of relief (plain, mountainous, rock city, area with negative shapes). The aim of study is to find the optimal method for each type of relief which expresses most of typical features. There are shown methods on the maps for orienteering sports for detection of different object from airborne laser scanning data. Keywords: airborne laser scanning, digital terrain model, data visualization, hillshading

The study of bryophyte species richness and community composition on a very fine spatial scale connected to in situ measured microclimate
Růžičková, Anna ; Man, Matěj (advisor) ; Marková, Ivana (referee)
The life of bryophytes is closely connected with their surrounding environment. Changes in atmospheric conditions on the microscale directly affect the physiological functions of bryophytes, which in turn determine their distribution. The current development of technologies allows us to measure the microclimate affecting bryophytes directly in the field. Nevertheless, there have not been many studies published examining the response of bryophytes to in situ measured microclimate. This diploma thesis is one of the first in Europe to provide data from continuous field microclimatic measurement performed on a scale relevant to bryophytes. It deals with the influence of the microclimate on the bryophyte species richness and community composition within a single gorge in the Bohemian Switzerland National Park. For 17 months, 38 HOBO Pro v2 Onset dataloggers were recording air temperature and air humidity 10 cm above the ground. I performed detailed bryological survey on two differently sized plots (circle with a radius of 1 or 2 m) around each of the dataloggers. The microclimate is influenced by the topography and character of the vegetation, therefore I derived topographical data from a digital terrain model (resolution of 1 m), calculated the canopy openness using hemispherical photographs and...

Evaluation of a Water Reservoir Bed Morphology Using Bathymetric Data
Jílek, David ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
Sedimentation of reservoirs is one of the current problems in the field of water resource management. The actual conditions of the bed morphology can be scan by modern bathymetric sensors or measuring and then transferred to digital terrain models. This bachelor thesis evaluates the process of the sedimentation of the upper reservoir of Nové Mlýny reservoir since its first filling in 1978 to the newest measuring in 2018 using an assessment of a water volume changes in the reservoir. The thesis also describes a detailed manual of reservoir volumes evaluation in the programs ArcGIS and Atlas DMT, and verification of the method accuracy. These programs were used for creating the digital terrain models and calculating area-volume curves that were utilized for evaluation of a volume change and then for the amount of the reservoir sedimentation. The total volume of the reservoir loss during the forty years is estimated as 500 thousand m3 which equals 28 % of the total reservoir volume, at least the 300 thousand m3 of sedimentation was realised in the last ten years. The outcomes are part results of the project ATCZ28 SEDECO – Sediments, ecosystem services and interrelation with the floods and droughts in the AT-CZ border region.

Mapování fluviálních tvarů na území CHKO Poodří na základě analýzy digitálních modelů terénu
Kruttová, Michaela
This diploma thesis deals with identification of fluvial shapes including their parameterization. Methods of automatic and semi-automatic identification of fluvial shapes applied to the digital model of terrain of the interest area are tested. The obtained data were compared to the real state of the territory. Based on the analysis of the elevation in the GIS environment, the optimal mapping method and its application in the selected area are selected. The result of this work is description of methods and analyzes for detection of fluvial shapes, complex map of fluvial shapes of the selected area and evaluation of the benefits of results for nature and landscape protection and management of Poodří Protected Landscape Area.

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.

Terrain break-lines detection based on Sky View Factor
Englmaierová, Tereza ; Brůha, Lukáš (advisor) ; Bayer, Tomáš (referee)
Terrain Breakline Detection Using Sky-view factor Abstract The subject of this diploma thesis is to propose the procedure of detecting of terrain breaklines using Sky-view factor. The theoretical part of the diploma thesis first introduces the issue of terrain breaklines detection, which presents the methods known to date and Sky- view factor, which is the focal point of the proposed method. Implementation over real data takes place at four locations in the Czechia (Vítkovice, Hradiště, Strnady and Velenka). Data in the form of raster format is tested. At the end, the results of the proposed method and its verification using two selected methods of field edge detection are presented and evaluated. Achieved results point to Sky-view factor for terrain edge detection. Keywords: terrain breakline, digital terrain model, Sky-view factor, detection terrain breaklines methods

Predictive distribution modelling of selected bryophyte species in Bohemian Switzerland National Park
Procházková, Martina ; Man, Matěj (advisor) ; Moudrý, Vítězslav (referee)
The aim of this thesis was to create potential distribution models for Dicranum majus (Greater Fork Moss) and Polytrichum alpinum (Alpine Haircap) in Bohemian Switzerland National Park. In the Czech Republic these bryophyte species occur in cold climatic regions typically with higher altitudes. In Bohemian and Saxon Switzerland they can occur in really low altitudes thanks to unique microclimatic conditions of deep inversion ravines. These bryophyte species had low number of occurence records in studied area before the start of my research (4 occurence localities for Dicranum majus, 8 occurence localities for Polytrichum alpinum). Predictive habitat suitability models can be an effective tool for selecting potential new occurence localities, planning field research or management design. During field research I recorded 34 new occurence localities for Dicranum majus and 29 new occurence localities for Polytrichum alpinum in Bohemian Switzerland National Park. I used 8 topographic parameters derived from digital elevation model with 1 m resolution as environmental data. Using these data I created models of potential distribution of the most suitable habitats for both species with algorithms Artificial neural networks (ANN), Generalised linear model (GLM) and Random forest (RF). RF algorithm had the...
