There is the topo map of Old Farm Hill Park, an undeveloped park in my neigherborhood, superimposed on the Google Earth (Mac) satellie view. Terrain setting is 2, so I could see if the countours of the land approximated the contours of GE's terrain.
Interestingly, from this angle, the street isn't quite matching as well as the contours are. The original map is very large. The electronic image I used is from a digital photo I took after spreading it out on my picnic table. When photographed, the topo map was not perfectly flat since its had a few adventures kicking around the house, so there is some distortion.
