In the region of Missouri my project is in we use Missouri State Plane, East Zone, US Foot. Our survey is in a modified state plane with a ground scale factor applied. Because of this, Nearmap aerials to not lineup properly. Typically off by a few feet. This is in AutoCAD Civil 3D. Any ideas on how to bring in the aerial if I know the ground scale factor so that it comes in and lines up with the survey?

Hello. Working with ground coordinates can through the alignment off but there is a way to bring the imagery back into alignment. The survey should include the scalars used which can be plugged in to manually shift the Nearmap data. I did a quick write up that you can reference here:
