Detection of anthropogenic terrain features in the summit area of the Luční and Studniční hora mountains (Krkonoše) with use of airborne laser scanning data
Krusová, Anna ; Lysák, Jakub (advisor) ; Potůčková, Markéta (referee)
The thesis focuses on detection of micrographic features using airborne laser scanning data. The aim of the thesis is to propose a novel method for detecting terrain features and to identify and describe terrain objects corresponding to anthropogenic interventions in the arctic-alpine tundra region in the summit area of the Luční and Studniční hora mountains in the Krkonoše Mountains. Based on existing studies, a new detection method of specific micrographic features was proposed by combining two types of data, i.e. point cloud and its raster representation. Initially, polygon approximations of terrain objects were derived from a digital terrain model, and their spatial delineation was further refined locally using point clouds. The output provides the most complete and accurate polygon delineation of the terrain features to date, considering the available data, the specific characteristics of the area, and in comparison to previously conducted studies. The proposed algorithm has identified hundreds of additional terrain features compared to the reference data. However, this number includes false positive features, which need to be manually eliminated. Key words: airborne laser scanning, micrographic features detection, archaeological prospection, digital terrain model, local relief model, Krkonoše...

Thematic atlas of the Prague islands
Krusová, Anna ; Lysák, Jakub (advisor) ; Janata, Tomáš (referee)
The aim of the work is to create a thematic atlas, the content of which are maps of selected lesser-known Prague islands, mostly inaccessible by foot. The partial goals are the identification of all islands in Prague using spatial data and analysis, evaluation of existing and acquisition of own spatial data, which are then used to create detailed maps of selected islands and processing of an atlas with additional texts and images. In theoretical part, literature and available sources of data on the Prague islands are researched and the work is placed in the context of cartography. The practical part describes the whole process of the atlas compilation, from the identification of individual islands through field survey to cartographic processing of the obtained spatial data and finalization of the resulting work. The output of the work is the Thematic Atlas of the Prague Islands, which was made made using ArcMap and InDesign software. Key words Prague, islands, thematic atlas, thematic cartography
