Need help aligning a DEM with georeferenced imagery & GCPs

Hello,

 

I'm working on a project where I've taken point cloud data obtained from a terrestrial laser scanner and converted it to a DEM using Lastools. I've also got aerial imagery taken from a helikite that has been georeferenced with ground control points. I now need to overlay those images onto the DEM so I can create a semi-realistic terrain model.


My problem is that the DEM and the georeferenced images don't line up even though they all have the same coordinate system.  I know I could georeference the DEM to the ground control points to fix it, but the DEM doesn't have any features that I could actually match to the control points.

 

Does anyone have any advice that would help me get around this issue?

 

Thanks,
John
