I am looking at an area (http://www.openstreetmap.org/?lat=39.36285&lon=-120.23967&zoom=17) where the streets, and the satellite images, are misaligned.
If I draw further roads, or fix details, should I trust the satellite imagery or the GPS?
What is the way for me to bring the imagery and the map back into alignment? For instance, if I can get an accurate fix of a few points via my GPS, what is the way to then make the satellite image conform to those points? I guess there could be a way to click on those points in the satellite image and manually enter their coordinates, and then have the image correctly re-mapped (with the system inferring the right tranform to remap the photo with minimal distorsion on the terrain). But how is it done in OpenStreetMaps?
