Geodetic CRS: CGVD2013a(2010) height
Datum: Canadian Geodetic Vertical Datum of 2013 (CGG2013a) epoch 2010
Data source: EPSG
Information source: IOGP
Revision date: 2023-07-17
Scope: Spatial referencing.
Remarks: Interpolation CRS = NAD83(CSRS) 2010, i.e. may be any one of NAD83(CSRS)v6, v7 or v8 (CRS codes 8252, 8255 or 10414). Equivalent to CGVD28 to CGVD2013a(1997) minus CGVD28 to CGVD2013a(2010) (i.e. CT code 10113 minus CT 10115).
Method: Vertical Offset by velocity grid (NRCan NTv2_Vel)
Description: (0,)
