Description

This tool provides easy-to-use access to the 'Copernicus DEM' global elevation data with 1 arcsec resolution (about 30 meter). 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 the directory the tool tries to download these from the Copernicus server.
