Hello flyzk,
Thank you for sharing the project data.
The problem is related to some internal algorithmic specifics. When the dense cloud is used for the mesh generation, the coordinates of the higher level hierarchical tiles are used and they appear to be outside the geoid area.
The workarounds that I see for this case are the following:
- generate the mesh from the dense cloud and then build DEM based on the mesh (with the interpolation disabled), probably tiled model will also work for this approach.
- expand the geoid file by extrapolating the no-data area (at least by 10-15 km from the area of use) and utilize the modified file as geoid.
Unfortunately, I don't think it could de fix quickly on our side, as it requires to modify the entire procedure of interaction with the geoid data, which would be time consuming and should be modified carefully, as something else could be affected.
