One Ground Control Point to Shift Map?
« on: June 24, 2020, 04:36:06 AM »
Typically, my drone's GPS is off by about 1-2 meters and up to 15 meters vertical.  If all I want to do is shift the coordinates of the resulting map to be within 0.5 meters  horizontal and 1 meter vertical, can I optimize the cameras with one ground control point that has 0.1 meter accuracy?

Hello jazzyj,

You can use single GCP with high accuracy in addition to the low accuracy camera locations.

Also, if you know the shift to be applied, you can add the same fixed X, Y and Z values to the source coordinates of every camera (it may be automated with Python) and apply the referencing.
