Ground control points explained: how GRAHAM locks drone maps to survey

By the end of this video you will know where to place ground control targets, how to shoot them with GNSS gear and how to tag them in DroneDeploy before processing. And Jack Buckley of the Graham Group will show you how to get it done. 🎯 What you'll see in this video: → How to choose GCP locations the drone camera can still pick out from 50 to 80 meters up → Why the target has to be shot with GNSS equipment to get millimeter accurate x, y and z positions → How the GCP file gets dropped into a DroneDeploy project and queued for processing → How the tagging screen handles points matched automatically and the ones that need a manual center click 📍 Want your cut and fill numbers to hold up from one flight to the next?
