Around here (S NV), particularly Red Rock, the GE photos are often misregistered by about 200'. In some very nearby places, the maps are spot on. GE is supposed to use wgs84 for plotting gps tracks; it's not a problem with me selecting the wrong datum, but possibly a confusion on the datum transition near RR, by the people who register the maps. I've written to GE several times, and the misregistration was fixed for a while, but with newer maps, it came back.
