In my experience it seems that the Bing streetside images usually have very accurate gps location data. I was thinking we could more accurately use the in-editor Bing image overlays to do orthophoto/satellite image offset alignments IF:
1.) Inside the image Bing streetside picture box there should be a red line going vertically down the center of the image.
2.) On the map overlay there should be a red line pointing out from the green dot in the direction of the camera center, instead of the cone we currently have.
Then we could use the offset adjustment to line up the 2 perspectives from 2 perpendicular directions and quickly have good accuracy.
