Unit: metre
Geodetic CRS: CGVD28(HTv2.0) height
Datum: Canadian Geodetic Vertical Datum of 1928 (Height Transformation version 2.0)
Data source: EPSG
Information source: Geodetic Survey Division, Natural Resources Canada.
Revision date: 2024-10-09
Scope: Derivation of approximate gravity-related heights from GNSS observations.
Remarks: Hybrid geoid realization of CGVD28. Defines CGVD28 where the levelling-based CGVD28 network (CRS 5713) does not exist. Both CGVD28 height and CGVD28(HTv2.0) height replaced by CGVD2013 height then by CGVD2013a height at epochs 1997.0, 2002.0 and 2010.0.
Coordinate system: Vertical CS. Axis: height (H). Orientation: up. UoM: m.
