WSRN Geodetic Reference Framework
The geodetic policy of the WSRN is to constrain all WSRN stations to the National Spatial Reference Framework (NSRS) of the National Geodetic Survey (NGS). Some of the WSRN stations are NGS CORS, others have been bluebooked at the NGS, and the rest are constrained to NGS CORS through a rigorous network adjustment.
All ellipsoid heights shown on this website are in meters unless otherwuise stated
