Regional grids : Vietnam

This dataset contains a set of complete gravity anomaly grids and maps (i.e., Free-air, complete Bouguer and Isostatic Airy-Heiskanen) determined for Vietnam and its surrounding areas at BGI (see references below). These products computed at 1' resolution were obtained from the combination of heterogeneous data including 29,121 cleaned-up terrestrial gravity points, global gravity models, and high-resolution topographic and bathymetric data. - Vu D.
