Simplification of buildings based on typification
Gottstein, Otomar ; Bayer, Tomáš (advisor) ; Jindrák, Přemysl (referee)
Simplification of buildings based on typification Abstract The diploma thesis is focused on cartographic generalization. Its main aim was to develop a new method of simplification of buildings based on typification for areas with lower density of buildings (rural or mountain areas). The proposed method was designed for large scale maps (1 : 25 000 and 1 : 50 000). The presented generalization algorithm is based on preferential selection of buildings to be drawn on the map according to their civic importance, area and location towards roads, railways and streams. It respects cartographic rules used for this type of generalization. The algorithm was implemented in the Python programming language using the Shapely and Fiona libraries for a purpose of its proper testing. The ZABAGED and DATA50 data were chosen as suitable test data. Among other things, this thesis also introduces the evaluation method of typification results, which uses Voronoi diagram. Achieved results are presented on maps of fifteen villages with different spatial structure in both targeted scales. Keywords: digital cartography, generalization, typification, building, simplification

Analysis of the vastness of castles and their depiction on early maps
Gottstein, Otomar ; Bayer, Tomáš (advisor) ; Čábelka, Miroslav (referee)
Analysis of the vastness of castles and their depiction on early maps Abstract The bachelor thesis is focused on the analysis of the vastness of the 21 biggest castles in the Czech Republic and their depiction on selected early maps of Bohemia and Moravia. For the purpose of analysis of the vastness there are defined geometric criteria in the thesis. These criteria take account of both the overall layout of the castle complex and the individual elements of the castle layout. All of these criteria are also applicable to all analysed castles. The analysis of vastness is realized with ArcGIS software; main source of data are geodetic plans from National Heritage Institute, additional data sources include Orthophoto CR and Digital Terrain Model 5th Generation. The numerical results of the partial criteria, presented in the results of the work, make it possible to determine the largest castle in our country or the castle with the biggest area according to individual elements of the castle layout. The analysis of depiction of castles on early maps is focused on the development of the cartographic symbol used for representation of these objects, the frequency of castles and used nomeclature in selected maps. Another part of this analysis is a cartometric analysis evaluating the accuracy of the depiction of...
