I added this later in the import, mostly to make the import easier. There were a few counties that I had to go back, blow away later, and reload. This was invaluable for that. > tiger:source, tiger:upload_uuid: appears to have been added by the upload bot > Usefulness: low to nil.

Basically, I could tell if it was me, or someone else doing the upload. There were a few people who jumped the gun and uploaded the same data as me, and this helped me figure out if it was a bug in the upload scripts or a person doing it. -- Dave _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
