The Canadian Gravity Geoid

A detailed gravimetric geoid has been computed on a 10' by 10' grid for Canada by the University of New Brunswick. This data base was received in April 1989. Principal gravity parameters include latitude, east longitude, and total geoidial height above GRS'80 reference ellipsoid. The gravity data used for the spheroidal Stokes's integration consisted of point gravity anomalies for the innermost zone, of 5'x5' mean gravity anomalies for the inner zone, and 1x1 degree mean gravity anomalies for the outer zone. The gravity values are based on the International Gravity Standardization Net 1971 (IGSN71) and the reference ellipsoid 1980 (GRS80). For detailed documentation see Technical Report No. 129.
