From OpenStreetMap Wiki
Working mostly in North Edinburgh using:
- JOSM (Because Potlatch is only fun for the first 10 minutes :P)
- exiftool (great for sub-second image geotagging)
- BT747 (essential for use with my Qstarz GPS track logger - the software it came with was borderline useless)
I discovered OSM January 2010 and was instantly hooked.
