Additional Information
The dZ value from the adjustment report does not measure the difference between the Digital Surface Model (DSM) and the input Ground Control Points (GCP) coordinate; rather, it measures the difference between the input Ground Control Points (GCP) coordinate and the adjusted Ground Control Points (GCP) coordinate. When processing with Ground Control Points (GCP), the Ground Control Points (GCP) locations themselves undergo minor adjustments to find a solution. This is the same behavior as common photogrammetry software, whose dZ values compare the initial vs adjusted Ground Control Points (GCP) locations, not the surveyed Ground Control Points (GCP) location and DSM output.Steps to Reproduce
