Forum Post: RE: Trouble with Control Points
Couple of things .. 2 to 3cm accuracy from drone for this sort of job is optimistic .. the basic rule-of-thumb is Accuracy = 3 x GSD ... so you are shooting sub-cm pixels - for 15km of road .. probably...

Suspect you are looking at ellipsoid versus geoid .. your SRS in context will likely be WGS + vertical override .. can DJI give you an ellipsoid height?

thanks for the idea, I can change the transition key - adjust the increment

With the current AT done from RTK .. create four or five user tie points around the model - including the known point. Get the coordinates of those points in the same coordinate system as your known...

An example might be easier .. Say we have five nice reference points in the current model - intersection of tiles, edge of concrete, painted line on the road .. whatever - something you can pick in the...
