NT Tanumbirini Elevation Grid geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This NT Tanumbirini Elevation Grid geodetic is elevation data for the Tanumbirini-Broadmere-Velkerri merge, 1983-2007. This survey was acquired under the project No. 1340 for the geological survey of NT. The grid has a cell size of 0.00083 degrees (approximately 91m). This grid contains the ground elevation relative to the geoid for the Tanumbirini-Broadmere-Velkerri merge, 1983-2007. It represents the vertical distance from a location on the Earth's surface to the geoid. 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.
