Description:

For the upcoming North American-Pacific Geopotential Datum of 2022 (NAPGD2022), the United States National Geodetic Survey (NGS), the Canadian Geodetic Survey (CGS), and Mexico’s National Institute of Statistics and Geography (INEGI) have computed the first joint experimental gravimetric geoid model for North America. xGEOID20A/B are 1'×1' grids for the region bordered by latitude N0° and N85°, and longitude E180° and E350°. For this joint effort, NGS and CGS computed geoid models using a common dataset, but each agency used their own computational method. This report records this joint effort and shows the model evaluation results.
