Source data: ebee images in WGS84, no GCP’s.
Desired output: WGS84 (x and y), vertical datum: heights relative to MSL on EGM 2008 geoid.
Heres the issue: The heights after selecting MSL are still showing a negative value.
We know the geoid/ellipsoid separation is approx -33m.
After entering -33m in the next option, results after Optimisation are still showing negative numbers.
Its as if the offset is not being applied by Mapper.
Also - if I change the offset value to positive 33m, the resultant heights after optimisation are -90m!
The whole thing is completely weird. All I want are orthometric heights relative to MSL.
