LGRB-BW RAW: Underground extraction of raw materials closed (points)
Description
The punk dataset includes the discontinued underground profit stops of the LGRB’s raw material extraction sites database. The representation is mainly carried out as a focus coordinate of the mines. The collection points entered in the database have a unique name (operation ID), which consists of the TK25 sheet number and a serial number (archive number, Arnum for short). This means: (1) Arnums up to and including 99: Extraction sites that have been collected since the mid-1980s as part of the raw material protection concept. (2) Arnums from 100 to 299 inclusive: Extraction sites collected in the 1950s. (3) Arnums from 300: Extraction sites which had already been dismantled before the mid-1980s. The coloring of the symbols is based on the raw material groups.
