Hello,

I have a project which involves 6 different locations within roughly 12km from the north to south end. Each location is quite small and will only have about 20 pictures. We require high accuracy so we we’re going to use an on-site base station placed roughly halfway between all the locations and then collect one high-accuracy GPS point at each site.&nbsp;

I’ve never done this before in Pix4D (Desktop), will this work?

The below screen shot show the 6 different locations.

Stephen,

I have replied to your support ticket. 3 GCPs need to be used for every project. 5 GCPs are recommended. One GCP will not work because it will not distribute the errors correctly.
