World Gravity Map (BGI)

The World Gravity Map WGM2012 is a set of 1:50000000 scale maps of the Earth’s gravity anomalies (Bouguer, isostatic and surface free-air) realized by the Bureau Gravimétrique International (BGI) as a contribution to the Commission for the Geological Map of the World (CGMW) with support of UNESCO, International Association of Geodesy (IAG), International Union of Geodesy and Geophysics (IUGG) and International Union of Geological Sciences (IUGS).
