Description

This tool provides easy-to-use access to the 'Digitales Geländemodell 1m (DGM1)' elevation data from the OpenData server of the Bayrische Vermessungsverwaltung (Bavaria). It uses a local database in the chosen directory which provides the original tiles. If the tiles covering the requested area are not found in this directory the tool tries to download these from the server.
