I saw a post on Tech Crunch announcing that Flickr had introduced Geo Tagging (finally!).
I tried it out and I am well impressed, I have to say. It recognises photos which have been previously geotagged and asks if you want to import them. It allows batch tagging (if you have several images which were taken at the one spot) and it uses a simple drag and drop interface.
You access the functionality by clickong on the Organize menu (not the dropdown but the Organize menu itself) and then choose the Map tab – not the most intuitive but after that it is entirely straightforward!
Where now is Zooomr‘s usp?
UPDATE: I see the Flickr blog now has a post on this
