Remarks

Reversible alternative to WGS 84 to MSL height (1) (code 8037). Parameter values are from WGS 84 to WGS 84 + EGM2008 height (2) (CT code 9618) assuming that the EGM2008 surface equals MSL surface within the accuracy of the transformation.

Frequently Asked Questions

What is the accuracy of the WGS 84 to WGS 84 + MSL height transformation?

This transformation (EPSG:9706) has an accuracy of 0.5m using the Geog3D to Geog2D+GravityRelatedHeight (EGM2008) method. Area of use: World.
