Geotagging With Old Satellite Data

This weekend I was explaining to a friend the new geotagging capabilities in Flickr and other online photo sites. After posting a photo from my Treo 600, I ran into an interesting phenomenom when I went to geotag it: what happens when the physical structure or location is significantly different now versus when the satellite data was taken. Streets, rivers, and towns don’t need to move around much, but in this case the venerable Stanford stadium has been completely rebuilt over the past 9 months. So, I made a best guess while tagging. Whenever the satellite data is updated again, I can see how accurate I was! (Flickr link)

Looks like Google and MSN also show the old stadium, so their data is also at least 9 months old.
