I have successfully created a custom coordinate system for the Select GCS dialog box for Baltimore City in Maryland. I started with a MD State Plane USFeet GCS and changed the false Northing and Easting using data from a PRJ file. When I export to Google Earth, it lines up and if I reference files between this custom GCS and one of the MD State Plane USFeet GCS, as long as I let it do a re-projection, the files line up.

Actually no, it would not geo-reference. I simply used a Cartesian system. that seemed to work okay for the mesh, but now i cant figure out how to create the ortho image because it is not geo-referenced per say.

The pictures were geo tagged, but i did have ground control that i used for aerotriangulation to orientate the flights and that seems to have worked okay.

Hi,

How have you georeferenced the model in ContextCapture? Were the camera positions known? Or did you add Ground Control Points?
