Marking GCPs from arbirary grid

We are provided GCPs in an arbitrary local grid on construction sites. Our drone is the DJI M300 RTK so the images are geolocated. I’m trying to figure out the best process for adding and marking the GCPs. Do I run the step 1 then import the GCPs and mark them in ray cloud? Or do I add the GCPs prior to step 1? When would I use the Basic method for marking?

Thank You

Hi Doug,

You will have to use the Basic GCP editor. This is because Mapper does not know how to display arbitrary coordinates. You can mark your GCPs before step 1.
