The first building tagged source = sketchup2osm is already in the OSM database:
I'll release the source code by the 23th of February. I need to clean up the source code and write documentation.
It will be possible to map buildings using 1-2 ordinary photos via Photo Matching feature of Google Sketchup.
- Import of an OSM file to Google Sketchup
- Import of a gps-track in NMEA format to Google Sketchup (support of GPX format comes a bit later)
- Export from Google Sketchup to an OSM-file
