The map is part of the administrative regulation cavity areas of the Saxon Oberbergamt. It contains areas where underground cavities are known (cavity areas) and areas with underground cavities that are subject to the scope of the Federal Mining Act (areas with mines under mining supervision). The cavity areas shown in the cavity map include the digitized areas of the thematic map Old Mining on a scale of 1:25000. More information at https://www.oba.sachsen.de/hohlraumkarte-4918.html
