Location accuracy improvement of watercourses based on airborne laser scanning data
 Peterková, Tereza ; Brůha, Lukáš (advisor) ; Tippner, Aleš (referee)
The object of this thesis is to propose the method of location accuracy improvement and longitudinal profile of watercourses using the data of airborne laser scanning. In the thesis the watercourses are seen as valley lines where i tis possible to use the method of terrain brek-lines detection to determine their location. The proposed method processes DMR in the formo f filter point swarm and i tis based od the intersection of planes approximation the slopes adjoined to the watercourse. Primarily the thesis focuses on narrow watercourses in deeply placed valleys and the method is adapted to it. At the same time the proposed method successfully deals with the different accuracy of the primary estimation of the explored watercourse. The end of the work presents and evaluates the results of the used method and the obtained data of the Labe spring region in Krkonoše mountains.

Automatic Detection and Cartographic Generalization of Spot Heights from Digital Terrain Models
 Polášek, Petr ; Lysák, Jakub (advisor) ; Tippner, Aleš (referee)
The aim of this work is to design automatic detection of spot heights from airborne laser scanning data and its generalization. The first part is about the idea of spot height: the importance of spot heights for altimetry representation on maps and suggestions concerning the scatter of spot heights on maps. In the following part, different approaches for terrain critical points extraction (peaks, depressions, passes) from digital terrain models are described as suitable places for spot heights location. Further, we introduce a description of geomorphological characteristics of these points by which is possible to identify its significance and generalize them. In accordance to analysis of Základní mapa ČR and recommendation for spot heights location described in literature we designed own method of automatic generation and generalization spot heights from digital terrain models. This method were implemented and there is a description of the test data and results on the real data DMR 5G of the algorithm in the end of the work. Powered by TCPDF (www.tcpdf.org)
