Notice: The Canadian Geodetic Survey (CGS) is releasing a new version of NAD83(CSRS) and a new velocity grid NAD83(CSRS) v8 - NAD83v80VG

Station Report

Geoid velocity added

To correct for the vertical drift between reference frames, the velocity of the geoid height (VN) is now calculated and incorporated into the calculation of the orthometric height. View documentation to learn more.

Vertical Data (levelling)

Vertical Datum Elevation (m) Order Gravity (mGal) Published Project ID
CGVD2013 (2010.0) 99.719 1st 980390.78 2013 H13ML1311
CGVD28 100.149 1st 980460.08 1974 VANO
IGLD85 100.233 1st 980619.90 1992 IGLD85AP92

The CGVD2013 height reported in the Vertical Data table is approximate because it is calculated from historical levelling data and not from the combination of GNSS and a geoid model.
