This method returns the terrain coordinate system. Each terrain database includes its coordinate system, with this method you can retrieve this information. This method is similar to ITerrain3::GroupKey, ITerrain3::DatumKey etc.
HRESULT GetTerrainCS(
[out] VARIANT*bstrGroupKey,
[out] VARIANT* bstrSystemKey,
