Moving checkpoints after aligning and optimising
« on: July 06, 2019, 10:52:36 PM »
Forgive me - beginner's question...

I'm doing a topographical survey using DJI Inspire 2 /X7 and following the famous (& excellent) SAV workflow for GCPs and checkpoints.

On completion, I noticed that some of my checkpoints (which were not used as GCPs in the processing) are in various different positions as I move between the photos in which they feature.

Two questions:
1) is it necessary for error checking after the processing workflow to filter the images by a given checkpoints and position them against the photos?
2) am I correct to assume that the fact the markers are moving between images like this suggests a significant error has crept in?
