Maybe some on can help me with this?
Have done a test project with 3D X-8 M here on Aruba.
We use 3 GCP because of the small area. Also we did a check with rtk gps on the area. I have found errors of 30 to 50 cm in the elevation? How is this possible?
The report give a 3D accuracy of 3 to 4 mm?
any help will be welcome.
thank you in advance
