I'm a research assistant at the University of Passau and am a long-time contributor to OSM mainly in Germany. I'm interested in free software and open data. My special interest is in 3D where I help Tordanik with his project OSM2World and am as that running the OSM2World-SlippyMap.
All my contributions to OpenStreetMap are released into the public domain. This applies worldwide. In case this is not legally possible, I grant anyone the right to use my contributions for any purpose, without any conditions, unless such conditions are required by law.
