Coordinate transformation bug

Hi, I have a gmw file that works perfectly fine with GM 26.2, but generates the errors in the attached file with v27.0. The result is that a huge number of files do not load.

All the files data are in the right folders, otherwise v26.2 would not see them. It seems to me that the key lines are those:

WARNING: Unable to find a usable coordinate transformation from 'Equidistant_Cylindrical' to 'GCS_INTERPLANETARY_MARS_2000'.

This transformation is operated by v26.2 but not 27.0.

Thanks,

Hi Daniel,

This is a known issue in GM 27.0 with the new projection engine. We are working on adding support for those (internal issue GM-21903) in an upcoming update to GM 27.0. For now, you would need to continue using GM 26.2 to support the non-earth systems.

Thanks,

Mike
