Observed gravity map, Canada: M183-2/8078-PDF
Carte des valeurs observées de la gravité, Canada /
"This map presents the observed gravity field over Canada. The data were compiled from the holdings of the Canadian Geodetic Survey, Surveyor General Branch. They were collected to map the gravitational attraction over the Canadian landmass and offshore areas. Variations in the force of gravity are due to differences in the mass of underlying materials, however, the gravitational effect of Earth¿s shape dominates over the contribution to the field by geological features. The gravity field is also used to define the geoid, which is the ideal shape of Earth, or mean sea level if Earth were completely covered with water"--Summary provided by publisher.
