CGVD28 height to CGVD2013a(2002) height (2)

Attributes

Geodetic CRS: CGVD28 height

Datum: Canadian Geodetic Vertical Datum of 1928

Data source: EPSG

Information source: Geodetic Survey Division, Natural Resources Canada.

Revision date: 2024-10-09

Scope: Change of height to a different vertical reference surface.

Remarks: Equal to HT2_2002v70 hybrid geoid model minus CGG2013a geoid model (CT 9985 minus CT 10110). Specified interpolation CRS is NAD83(CSRS)v4, but NAD83(CSRS)v2 or any later realization may be used without error. See also CT 10618 from CGVD28(v2.0) height.

Method: Vertical change by geoid grid difference (NRCan)

Area of use: Canada - onshore - Alberta; British Columbia; Manitoba south of 59°N; New Brunswick; Newfoundland, Labrador between 52°50’N and 54°30’N; Northwest Territories south west of a line between 60°40’N, 110°W and the coast at 132°W; Nova Scotia; Ontario south of 52°20'N; Prince Edward Island; Quebec - mainland south of 55°N and west of 64°W, north of 55°N between 70°W and 66°W, coastal area between 66°W and 64°W, and Anticosta island; Saskatchewan south of 58°30’N; Yukon.
