.. and see where you have been
And Google is making more things possible again by combining the forces of two applications. It is now possible in Picasa Web Albums to exactly pinpoint where you have taken your pictures.
You can also create a kml file that allows you to show the pictures in Google Earth. This makes Picasa Web Albums come close to Panoramio. Only difference is that anyone can now easily see the pictures uploaded to Panoramio by any user. I expect that the public photos on Picasa Web will be visible in a layer in Google Earth pretty soon.
Google did buy Panoramio recently and they have a very thorough history of integrating applications.
It will make looking around in Google Earth even more fun. Seeing pictures taken by neighbours of your own neighboorhood. Better than looking for a cat in Street View!
Google Maps now already shows the Panoramio pictures in the My Maps context. So things are rolling. The game's afoot!
Now here's a fine example of a Panoramio picture on Google Maps. Be sure to go to the My Maps tab and select the Panoramio layer. There is panoramic view uploaded by me.
