Manual referencing with battery swaps

If I intend to use GCPs, do i need to include the "ground shot" images when i upload the aerials?  I seem to remember reading that if you use multiple batteries, the ground shot images are no longer useful for DEM generation. 

Thanks, Jim L.

As long as all of your images were taken from the same takeoff location you only need to include one ground reference image for that whole set. That will help get the elevation as close to the accurate number as we can get. Then when you use GCPs the offset will likely be pretty small.
