Hey Dan,
Thank you for sharing an image that clarifies your concerns.
Our understanding is that you should not consider the geotag that DJI’s Matrice 210 RTK report in each images’ EXIF as centimeter-grade. The offset between the camera and the GPS is one part of the equation that must be taken into account to achieve cm-grade geotags.
Please consider joining the ongoing discussion about DJI Matrice 210 RTK geotags and Pix4D at Matrice 210 RTK to learn more.
Thank you for your understanding and contribution.
