Currently this data is available through the Subversion repository of Ggr's MapUtils: http://svn.pupunen.net/public/maputils/trunk/maps/ You may also be interested in the utilities themselves http://svn.pupunen.net/public/maputils/trunk/ and especially the file "README.loc", which contains some documentation on the format of *.loc-files.
Also, Bat Ry provides the raw ASCII map data for the BatMUD continents: http://www.bat.org/maps/raw/
