CGVD2013a(2010) height

Attributes

Unit: metre

Geodetic CRS: CGVD2013a(2010) height

Datum: Canadian Geodetic Vertical Datum of 2013 (CGG2013a) epoch 2010

Data source: EPSG

Information source: Geodetic Survey Division, Natural Resources Canada.

Revision date: 2023-01-12

Scope: Geodesy, topographic mapping.

Remarks: Replaces CGVD2013(CGG2013) height. Although its datum is static CGVD2013a heights change with time, primarily due to glacial isostasy. This CRS is a static snapshot at epoch 2010.0 for use with NAD83(CSRS)v6 and v7. For other epochs see CRSs 20034/20035.

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.

Coordinate system: Vertical CS. Axis: height (H). Orientation: up. UoM: m.
