Orthorectification problems

Hello,

I'm setting up an image services that serves orthorectified aerial images.  A lot of the output looks good, but there are quite a few mis-alignments.  I don't see any consistency between the problem areas.  See attached screen shots for typical examples.

The image service uses and rpdef file to define camera interior orientation, and the image exterior orientation parameters are in a dbf that reference the rpdef file.  The service uses a DEM that I believe is accurate.  The inaccuracies are not necessarily close to changes in elevation, so I don't think that the DEM is likely to be the problem anyway.

I would appreciate any suggestions on how to debug the problems.  

I'm new to this, so I might be overlooking something obvious.

Thanks.

David
