We were trying to process the Anafi Drone Data using Pix4D Software for a Quarry Area.
The Drone Mission contains 566 Images which were processed to get the Ortho Images, DTM, DSM & Contours.
After studying the data we have observed that the DTM / Contours generated by Pix4D have issues with the elevation information.
Figure-1 shows the Elevation in a cliffed zone where it should not be.
Figure-2 shows the Elevation Difference of 7 Meters along a ROAD (12 Meter width) which is practically impossible.
It would be great if someone can advise me where the error peeped in.
Thank you in advance and have a great day!
