Tie Points to GCPS
« on: March 02, 2015, 07:49:05 PM »
I am using the Cosi-Corr add-on in Envi, and am attempting to convert tied points to GCPS.  However, I get an error message saying that my HiRISE image and DEM do not have the same datum.  In fact, the HiRISE image's datum is : D_Unknown, and the DTM's datum is: D_Sphere_Mars.  In the end, this may be a simple question, but how am I suppose to define the HiRISE's datum in ENVI?

Thank you,

   I assume the radius values are the same it might just be a matter of the name used. Have you tried to simply edit the header? If you can't, because of the format, you might need to convert to and ENVI format and then edit.
