Correlator3D is unable to generate a DSM using the supplied input data

hello community,
I wonder if you guys have seen this message before? I wonder if it is in fact related to a DEM we are trying to import...

Hello Brodie,
Sure, let me list a couple of possible causes:
- Insufficient overlap between images is a common cause. Generating a coarse DEM using the Aerial Triangulation module and verifying the footprints can help identify an issue.
- The resolution you specify for the DSM might be either too high or too low. While Correlator3D supports a wide range of resolutions, some projects might have some particularities that do not allow a certain resolution.
- The aerial triangulation that was performed on the project is problematic. You should consider validating your AT results again and make sure that all disks are green and that calibrated camera parameters are not out of expected bound.
The same recommendations apply when the message "There is no overlap between the images. Skipping, continuing with next entry" appears for some images in the log window.
keep us posted!

Hey David,
Thank you for the help, it was related to the resolution being to low, I sent the DEM back to the team and they kicked out a higher resolution DEM that worked like a charm.
Again, thank you very much for the help.
Brodie.
