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?
I don't know how secret these are, but:
http://mapcenter.cgpsmapper.com/catalogue.php?country=55
http://mapcenter2.cgpsmapper.com/catalogue.php?country=130
*How* free these are varies from map to map. As well as the quality.
These are in so called Polish format. Most complete description is
available in cGPSmapper manual AFAIK [1]. There is a freeware (closed)
program for converting them into Shapefiles [2]. Some other converter
[3]. Mateusz Loskot has worked on an OGR driver, but I don't know
details (CCing him).

P.S.
Please better ask generic free GIS data questions on FreeGIS ML.
