hi,
1.can Reach collect 2cm accuracy GCP by camera triggering events?
how to do this?
2.what modifications needs to be done to my phantom 3 pro?
3.what can affect accuracy, and what accuracy can i expect in final product?

my final product needs to be very accurate orthomosaic and contour lines. (probably using pix4d or similar).
