Geodetic CRS: NAD83(CSRS)v3
Datum: North American Datum of 1983 (CSRS) version 3
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: Canadian Geodetic Survey, Natural Resources Canada.
Revision date: 2024-03-16
Scope: Change of coordinate epoch in 3-dimensions (φλh).
Remarks: The v6 velocity grid is not recommended for height transformation north of 60°N due to due to inaccuracies in the vertical component of the velocity model. Replaced by NAD83(CSRS)v3 to NAD83(CSRS)v4 (3) (code 10528).
Method: Geographic3D Offset by velocity grid (NTv2_Vel)
Description: (0,)
