GEOID '88: A gravimetric geoid for CanadaUsing Stokes' formula, a gravimetric geoid was calculated for Canada. The input data are as follows: 15 x 15' block averages were used for Canada and the USA and 1 x 1 deg block averages and satellite model (GEM-T1) provided values for the remaining part of the Earth. The geoid was calculated at 6398 points covering the area within the points rho(sub i)(phi sub i; lambda sub i) (lambda is + west): rho sub 1(40,125); rho sub 2(75,184); rho sub 3(75,10); and rho sub 4(40,60). The computed geoid refers to the GRS1980 and reaches a local minimum of -47.3 meters around the western part of Hudson Bay. A contour map of the geoid is shown.
