I've been using Pix4D for a few years and am very familiar with the software. We recently flew +/- 1200-LF of roadway at 60-M in elevation at 5-MPS w/ +/- 90% overlap. Generally we get very good results with these specs. However, for some reason the vertical error is significant. See attached Quality Report.
Does anyone see anything in the report that may indicate why the error is so high? Thank you for your help.
