What is the work flow to process RTK uav imagery?
« on: September 13, 2025, 06:35:35 PM »
Generally, what is the process to run rtk imagery in Metashape? I work with rtk data all the time but usually end up just disabling it to work with the gcps, which is better anwyays. BUT it would be nice to know how to use the rtk data from the drone, whats the point of using it anyways? Can someone explain how to do this? A lot of times after I bring the gcps into the RTK data, the gcps are still way off. I know the rtk images are more accurate than that.

In the preferences turn on all the xmp import stuff.

Make sure it in the same directory as your image.

when you import the directory it will import the RTK data and you will see in your accuracy.

Issues I have had is once I use my ground GCP's  to verify my errors I find my errors get bigger.

This is most likely because you need to reproject the drone images into the GEOid used to measure the GCP, with correctly setup RTK you will get spot on GCP.
