You know how most imagery is offset, and you need to align it with GPS traces and other stuff before mapping? No? Haha.
My another project from that time was the Imagery Offset Database. A huge list of reference points than helps align imagery automatically. Complete with a JOSM plugin and tons of documentation. Turned eleven last month, still very active.
iD editor was written by americans with perfect imagery, so it still doesn't support it:
The key to IODb's usefulness is collaboration: by using the stored offsets, you indirectly interact with other mappers to share the work.
Direct interaction was made possible with the GeoChat JOSM plugin. You see somebody having the same area open in JOSM — you say hi. Also helps avoid conflicts.
The protocol and the server are very simple (and hosted on OSM dev instance), I'm suprised it still works. Maybe somebody should remake it for modern age and mobile editors...
