Wired recently reported on a newcomer to the street-level imagery map game. They're called MapJack, and if they can expand quickly enough to cover the ground Google has already claimed, they'll give them a good run for their money. The concept is the same–you click around on a map and see photos of the street–but beyond that, the two diverge. MapJack's imagery is many times sharper, larger, and more dynamic than Google's. The site offers a sophisticated array of controls, both in navigating the street and the view and in controlling the image display. I found it much more responsive and vibrant than Google Maps. Lining up a particular address or orientation is a snap, like it should be.
