Full description

This grid provides the elevation values that define the observation surface for the "A" series grids relative to the GRS80 ellipsoid for the GDA94 datum. The "A" Series grids were produced from a combination of ground gravity data for Australian onshore locations, gravity data derived from satellite altimetry for offshore locations, and gravity data from the EGM2008 global gravity model for the onshore locations in countries other than Australia.
