Gawler Craton Airborne Survey Merge Digital Elevation Model - ground elevation geoid grid

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Gawler Craton Airborne Survey Merge Digital Elevation Model - ground elevation geoid grid is elevation data for the Gawler Craton Airborne Survey Magnetic Radiometric and DEM Merge, SA, 2017-2019. This survey was acquired under the project No. 5000 for the geological survey of SA. The grid has a cell size of 0.0004 degrees (approximately 41m). This grid contains the ground elevation relative to the geoid for the Gawler Craton Airborne Survey Magnetic Radiometric and DEM Merge, SA, 2017-2019. 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.
