资源简介：
This grid provides the elevation values that define the observation surface for the "B" series grids relative to the GRS80 ellipsoid for the GDA94 datum. The "B" Series grids were produced using the gravity data in the A Series grids but also include data from a number of airborne gravity and airborne gravity gradiometer surveys.
