DJI Phantom 4 RTK | Drone Mapping Workflow

DJI Phantom 4 RTK | Is the Drone Mapping Workflow Significantly Different?

In today’s show, we discuss the mapping workflow for DJI Phantom 4 RTK. How does the drone mapping workflow differ from non-RTK drones like the Phantom 4 Pro?

Our caller, Lorenz from Wisconsin, is using a DJI Phantom 4 RTK for drone mapping. Lorenz is wondering if he needs to make any significant changes to his mapping workflow. Are there any issues specific to Phantom 4 RTK users that Lorenz needs to be aware of?

In this very detailed show, DJI Phantom 4 RTK users will learn the most accurate and efficient drone mapping workflow. In the past, we have shared our experiences with the Phantom 4 RTK. While there are many advantages to this RTK drone, you will have to deal with some unique problems too. For instance, when you acquire data with the DJI Phantom 4 RTK, the datum for images and GCP’s tends to differ. What do you do in this case?

In this show, you will learn when and how to make changes and corrections to your coordinate system. You will learn about geiod height and whether you should set your geiod height above WS G84 ellipsoid. How do you make corrections when mapping a large area with different offset values? Will using the Propeller Aeropoints along with DJI Phantom 4 RTK result in more accurate drone mapping data? Thanks for the great question, Lorenz. Fly Safe!
