Today, Google announced that they've added satellite imagery (via their acquisition of Keyhole) to their Google Maps service. All of the features that are normally available have now been integrated with Keyhole's detailed overhead photography. In satellite mode, the system still superimposes driving directions, still pinpoints businesses, and still displays web links. Best of all, you can still drag the maps around with ease.
When Google Maps first debuted, people said that quickly dragging the maps felt like flying over land; they didn't know how right they were.
