Precision of Pick / Point measuremeent, point coordinate

1. A concise explanation of the problem you’re experiencing.

this is not a Problem it is a question

Does anyone have experience what precision a coordinate pick has depending on the used data (Terrain) and the Settings (zoom, …)

Normally in photogrammetric Point-measurement you will get a precision in objekt-space

SXYZ = q* mb * Sx’y’

depending on a factor q (Image Quality, method), mb scale of the Display, Sxy Accuracy of the Point measurement in Pixel (depending on signalized Points or nature between 1/20 to 2 Pixel)

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
