I used Google Earth to spy on my project. It happens to be one of the hi-res. quality photos. As I zoomed in, it dawned on me that it had a nearly identical visual quality as the strip maps that I requested from the NRSC office this last summer. Yeah, I realize that it IS the same photo, but the resolution, color and related qualities were identical. Presumably, either Google uses these same aerials or vice-versa....?
