Use of UAV hyperspectral data for training of classifications of data with lower spectral and spatial resolution on the example of vegetation classifications in the Krkonoše tundra Abstract The thesis focuses on the problem of supervised classification of the Krkonoše tundra with a limited amount of training data. UAV hyperspectral data of 100×100 m2 area on Luční hora from 2020 and 2021 with spatial resolution of 9 cm and 54 spectral bands were classified using Maximum Likelihood, Support Vector Machine, Object Oriented Classification and Random Forest algorithms. The defined legend contained 9 classes: Avenella flexuosa, Avenella flexuosa with high cover of other species, Vaccinium myrtillus, Deschampsia cespitosa, Pinus mugo, Nardus stricta, blosckfields, Calluna vulgaris, mosaic of rocks, bare soil, mosses and vegetation. The results of these classifications were compared based on their overlaps. The overlays of the multitemporal composite classifications, which achieve higher overall accuracies, are used to find more training data. The wider area of Luční hora was classified based on CASI hyperspectral aerial data with a spatial resolution of 60 cm and 48 spectral bands. The original training dataset designed for the classification of the smaller area and new training datasets extended with additional...

Tourist map of Srbsko in Český kras with focus on karren relief depiction Abstract The aim of this bachelor thesis is to create a large-scale tourist map capturing location of Srbsko (Český kras) and surrounding area. The focus is on karren relief depiction. The partial goal of the thesis is to collect and evaluation quality of the available spatial data useful for creating the large-scale map. As the main source of existing data are used ČÚZK data, JESO database and database OpenStreet Map, which is available for free. These data are suplemented based on field survey, which took place using the ArcGIS Collector and a GNSS receiver. The final part describe creation of the tourist map, that respects cartography rules and designing of the symbology. The map is a graphical output of the thesis and can be used as a folding map as well as a board map. Keywords: tourist map, large-scale map, topographic mapping, karren relief depiction, Srbsko (Český kras)
