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. {"type": "Polygon", "coordinates": [[[130.987, -32.6745], [138.0122, -32.6745], [138.0122, -27.3437], [130.987, -27.3437], [130.987, -32.6745]]]} 130.987 138.0122 -32.6745 -27.3437 Australia DEM EARTH SCIENCES Earth sciences Elevation GADDS2.0 NCI Published_External SA digital data geoid geophysical survey geophysics grid image raster survey 5000 terrain File available for download in various formats from the GADDS2 portal documentDigital The Geophysical Archive Data Delivery System (GADDS2) portal provides HTTP download of geophysics datasets in a number of formats.
