Roads and paths in geographical databases of Czech republic - analysis of their existence and geometric accuracy, the new proposal of classification Abstract The fundamental objective of this bachelor thesis was to assess the network of roads and paths in geographic databases ZABAGED, DMÚ 25, ÚHÚL, SHOCart and maps for orienteering. The analysis of roads and paths was based on the geometric accuracy and the existence in databases due to the targeted forest road network in a limited forested land. The measurement was carried out the tourist receiver GPS for fieldwork. This bachelor thesis is divided into three parts. Firstly the classification of road network databases are compared and the basics of their geometric precision are given. The second part is dedicated to the principle of measuring GPS and errors that might occur. The calculate the accuracy of the receiver of unfavorable conditions when the measurement is influenced by many aspects is included too. The third part deals with the actual comparison of databases focused road network. The main output is a detailed map of the area at a scale of 1: 10 000 measured with a network of roads and paths. Keywords: forest road, path, geographic databases of Czech republic, classification of forest road network, Global Positioning System
