Geotagging with Picasa Web Albums
Here is a proof-of-concept post: my Picasa Web Album of Historical Sites in the Spokane region. This came out of a drive that Bill and I did last summer to find the Mullan Road marker south of Cheney. I put the photos we took that day along with some others into a Picasa web album, and then used the geotagging feature to create a Google Map that displays the photos. (Note: I did not keep perfect notes on my GPS positions for some of these and I may not have them exactly right on the map.)
I am still experimenting with the features but I am really excited about the potential. Photos can be tagged so that a user could sort to view only those tagged with Indians or transportation or schools. There are comments as well as captions so visitors to the site can add information. And you can export the album into Google Earth.
I think it is possible to share a Picasa Web Album via a Google Group. The album would them become a wiki of historic photos taken by dozens of users throughout the area. And of course historic photos could be imported as well.
