State of the OpenStreetMap by Nathan Yau.
Nathan reminds us to review the OpenStreetMap Data Report, which includes a dynamic map showing changes as they are made.
OpenStreetMap has exceeded 1,000,000 users and 1,000 mappers contribute every day.
I wonder if the OpenStreetMap would be interested in extending its Features to include a “seen-at” tag?
So people can upload cellphone photos with geotagging of watchers.
With names, if known, if not, perhaps other users can supply names.
