    dct:description "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 image is elevation data for the Gawler Craton Airborne Survey Magnetic Radiometric and DEM Merge, SA, 2017-2019  relative to the geoid vertical datum. These data were acquired during  project No. 5000 for the geological survey of SA, and consisted of 1660000 line-kilometres of data at 200m line spacing and 60m terrain clearance. The grid used to produce this image has a cell size of 0.0004 degrees (approximately 41m) and 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." ;
