Last week Flickr announced a great set of enhancements to their service: geotagging of photos on a map. Once again they've done a nice job in the interface by making it really, really easy. Drag-n-drop them on the map and you're done. See this screencast for the how-to. As reported in the Flickr blog there were 1.6 million geotagged photos within the first day! On the API side they have added this set of 8 geotag-related methods . The most significant is being able to search for photos by location. I'm sure this will lead to some interesting mashups. Flickr has created their own handy mashup that of the over 2 million+ photos mapped so far. You can now find it in the database here. More good details on the new feature, as well as some issues, see this post from Thomas Hawk.
