Ground Control Points - How to Accurately Mark and Organize them

Today's question is about Ground Control Points (GCP's). What steps can you take to mark GCP's correctly, and ensure accuracy in drone mapping?

Our caller, Nate has come up with a great question that has not been asked on Ask Drone U before. Nate's question is about organizing GCP's in drone mapping. Should you use a map depicting the numbering and location of Ground Control Points?

In this show, you will learn how to mark and validate Ground Control points correctly. We reveal some common mistakes that drone pilots make, which results in incorrectly marked GCP's. Then, we proceed to share the workflow that will help you prevent these errors.

What is the minimum number of Ground Control Points that you should be using? Is using checkpoints necessary? And, how can our Drone U landing pads help you correctly organize Ground Control Points? We reveal the answers to these questions and more in this informative show. Tune in now!
