How to Set Ground Control Points for Greatest Accuracy in Construction Mapping

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 Ground Control Points. How many GCPs should you use? How should you lay them out? Can you use Propeller Aeropoints for setting Ground Control Points on a construction site.
