I almost hate to give this away, but the North Central Texas Council of Governments hosts www.dfwmaps.com, which will give you great maps and arial photos of the North Texas area.
The arial maps are within 75 meters I believe. Amazing detail.
The only downside is that it’s not as scrollable as Google maps or MSN, but otherwise it looks great. It’s got better photography of North Texas than either Google or MSN.
The picture above is of the doomed Super Conducting Supercollider outside Waxahachie.
Or it could be a photo of the Iranian nuclear facility?
