Today's question is about using ground control points in construction. What is the correct workflow for laying out GCPs on a construction site? Can you lay GCPs on a construction site and use this information again and again?

We have a great drone mapping question today. Our caller is wondering if he can get away with using Ground Control Points in the initial flight only. In order to answer his question, we discuss the entire workflow for laying out GCPs. How many GCPs should you use? How should you lay them out? Can you use Propeller Aeropoints for setting GCPs on a construction site.

Towards the end of the show, Paul has a great TIP for correcting Z axis errors using Ground Control Points. This show is loaded with some great information. Tune in now!
