[GRASS-user] Any freely available topographical maps for (South-) Germany ?

[Nikos Alexandris]

Dear all,

I was asked about freely available geo-data concerning the South of
Germany.

AFAIK, best available elevation data are the SRTM3 data. About
topographical data I am aware of some commercial data (1:25.000). The
friend who asked me is satisfied with a 1:50.000 topo-map.

Any "secret" sources?

Thank you,

Nikos
