The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. These line dataset from the NTGS Tanami NS Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey were acquired in 2018 by the NT Government, and consisted of 145230 line-kilometres of data at 200m line spacing and 60m terrain clearance.
