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

Making a historical map set of battle at Chlumec 1813
Blažka, Jan ; Čábelka, Miroslav (advisor) ; Bayer, Tomáš (referee)
Goal of this thesis is to make map set of battle at Chlumec (near Ústí nad Labem), where Napoleon's general Vandamme was defeated by retreating coalition armies at the end of August 1813. Main data source are old map of battle at Chlumec, gained from Map repository of Charles University, and layer of contour line from ZABAGED. After evaluating methods of making historic maps process for making maps of battles is designed. Several maps of the course of battle are made where only position of soldiers in time is different and also several maps of some commanders' views in particular moments of battle are made. Based on the finished maps evaluation and discussion are made, if battle could end otherwise or why it took place the way how we know it.

The analysis of battle maps of the Battle of Lovosice
Huneš, Matěj ; Čábelka, Miroslav (advisor) ; Bayer, Tomáš (referee)
The analysis of battle maps of the battle of Lovosice Abstract The bachelor thesis deals with the content analysis of old battle maps. At the beginning of this thesis there are analyzed important concepts on the topic and methods of content analysis of old maps. In the next step there are described the battle maps and there is also carried out a detailed analysis of the battle conflict at Lovosice. In the practical part, based on the information obtained from the previous chapters, there is content analysis of the six battle maps dealing with the Battle of Lovosice, which come from the Map Collection of the Faculty of Science. The maps are then compared and evaluated in terms of content and historical accuracy. In the second part of the practical research is described the procedure in the creation of a new historical map of the Battle of Lovosice, which used the knowledge from the content analysis. Keywords: old maps, historic maps, battle of Lovosice, battle maps, analysis map

Production of cartographically correct countour lines from airborne laserscanning data in flat terrain
Picek, Jan ; Lysák, Jakub (advisor) ; Bayer, Tomáš (referee)
Production of cartographically correct countour lines from airborne laserscanning data in flat terrain Abstract The thesis is dedicated to the creation of contour lines from the data of airborne laserscanning in flat areas. For creation of contour lines in these parts is necessary specific generalization, that smooths unwanted artifacts, but does not delete the shapes, which are characteristic for the relief. The first part of the thesis is to serve as a short insight into the areas on which it is built, this thesis: the principle of airborne laserscanning and basic information on the contour line model. On the basis of technical literature are defined the requirements for the correct representation of the contour and cartographicly presented the different types of the DEM and generalization of contours. The main aim of this work is to design an algorithm that will combine several methods of generalization of contour while maintaining altitude accuracy as well as other requirements on their cartographicly the right terms, and to test this approach in several territories. In conclusion, the results of the methods of work and its implementation critically evaluated and outlined other possible developments of this issue. Keywords hypsography, airborne laserscanning, digital cartography, contour lines,...

Representation of the world in early maps
Jílková, Petra ; Bayer, Tomáš (advisor) ; Semotanová, Eva (referee)
Representation of the World in Early Maps Abstract The thesis deals with an analysis of the representation of the world in early small scale maps in the 16th - 18th centuries. The theoretical framework consists of the outline of the historical context of the given period with emphasis on the representation of the world in connection with the progress of the discoveries and the expansion of the geographical horizon. The development of navigation methods and technical means used to determine the latitude and longitude that had a direct impact on the positioning accuracy of topographic map elements are depicted, too. The practical part of the thesis is focused on the cartometric evaluation of selected map works of European cartographers of the period of 16th - 18th centuries, which consisted of the analysis of cartographic projection and the analysis of the positional accuracy of topographic content. The geometric accuracy of the maps is assessed mainly by the value of the positional deviations in the north-south and west-east directions. Based on the results of the cartometric evaluation, the evolution of the topographic content positioning is determined and the approximate time process of expanding the image of the known world on the contemporary maps is captured. The graphical outputs of the thesis are...

Automatic generalization of 3D building models
Brýdl, Ivo ; Brůha, Lukáš (advisor) ; Bayer, Tomáš (referee)
The main aim of this thesis is to propose a novel method for generalization of 3D building models with respect to topology in 3D space. The first part gives an overview over spatial data structures and methods for generalization of 3D objects. The second part presents the methodology composed of volumetric mo- del reconstruction, topology validation and simplification of geometry based on mathematical morphology approach to build multi scale model. Method is then implemented and experimental results are presented. In conclusion results are discussed and possible improvements are suggested.
