Today Flickr seriously pumped up its geotagging support and added Yahoo! Maps integration. The announcement in the Flickr blog
links to a few screencast tutorials that make geotagging, i.e. associating photos with particular locations on the map, look pretty easy. It's done through the
Ajax-based Organizr tool, and basically you select a bunch of your photos and then drag them to the location you want to tag them with on the map. Similarly, you can explore other people's photos with a new map interface. You can go to flickr.com/map
to see everybody's photos and search by location and/or tag. Naturally, it's all done through the Yahoo! Maps API, which means you can zoom and pan around as well as see a satellite photo or hybrid view of the map. The Flickr update also includes integration with Upcoming.org: you can now tag your photos with a special tag for an Upcoming.org event and they'll be displayed on the Upcoming page for that event. Neat.
