EPSG:9124

ITRF2008 to CGVD2013 height (1)

Attributes

Geodetic CRS: ITRF2008

Datum: International Terrestrial Reference Frame 2008

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: OGP

Information source: Geodetic Survey Division, Natural Resources Canada.

Revision date: 2019-05-30

Scope: Derivation of gravity-related heights from GPS observations.

Remarks: Uses CGG2013 model derived through NAD83(CSRS)v6 which uses bi-quadratic interpolation; bi-linear interpolation of the grid file will give results agreeing to within 1cm 99.97% of the time. Replaced by model CGG2013a (CT code 9125).

Method: Geographic3D to GravityRelatedHeight (CGG2013)

Area of use: Canada - onshore and offshore - Alberta; British Columbia; Manitoba; New Brunswick; Newfoundland and Labrador; Northwest Territories; Nova Scotia; Nunavut; Ontario; Prince Edward Island; Quebec; Saskatchewan; Yukon.
