Hi everyone!

I have several building models in SWEREF99 which is the coordinate system used in Sweden. I successfully converted coordinates to WGS84-geocentric using csMapReprojector but buildings are now several meters above the surface of WGS84. How can I clamp those buildings to WGS84?

P.S: The height reference used in Sweden is called RH2000.

Thanks in advance!

If you have a height adjustment grid between RH2000 and WGS84, you can use it in the CsmapReprojector. Please see https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/csmapreprojector.htm and https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Coordinate_Systems/CoordSys/vertical_grids.htm for more information.
