I'm sure by now most of you are aware that Google has maps on there website. If you are not, you should check it out:
Anyway, they recently added something pretty cool to their maps. If you pull up one of their maps, you will see a link in the corner that says 'Satellite'. If you click on this link, it flips over to a Satellite imagery map. In full color even! The maps seemed fairly new to me. Perhaps around 2003 or so? Oh, one last thing. You can scroll these maps by clicking on the map and dragging them around. Very cool.
Anyway, I thought it was cool, so I thought I'd share with you all.
Edited to add: Hmm, I see they don't have total coverage. A lot of areas gives you the message that they don't have maps at that zoom level. Dang, hope they get all of the areas soon.
