GeoTagging Flickr is a Flickr group for discussing all things related to putting geotags onto Flickr pictures. The group also has a linklist to useful geotagging tools.
(Recap: Google Earth will show geotagged Flickr images if you subscribe to the geobloggers network link. More about this here.)
Notes on the political, social and scientific impact of networked digital maps and geospatial imagery, with a special focus on Google Earth.
