Geophysical Survey Datasets - Elevation
Digital Elevation data record the terrain height variations from the processed point-located data recorded during a geophysical survey. The data acquired are a mass of ground heights representing a terrain surface. The data are either geoidal (representing the vertical distance from a location on the Earth's surface to the geoid) or ellipsoidal (representing the vertical distance from a location on the Earth's surface to the ellipsoid). The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
