ANSWERS TO YOUR
TECHNICAL QUESTIONS.
Why am I getting the message "Correlator3D is unable to generate a DSM using the supplied input data"?
These are the 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.
