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 Southern Yilgarn (Newdegate, Ravensthorpe, Bremer Bay), WA, 2004 survey were acquired in 2004 by the WA Government, and consisted of 99719 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Mount Peake-Crawford - ground elevation geoid grid (laser) is elevation data for the NTGS Mount Peake-Crawford Magnetic, Radiometric and Elevation Survey, NT 2019. This survey was acquired under the project No. 1319 for the geological survey of NT. The grid has a cell size of 0.00019 degrees (approximately 20m). This grid contains the ground elevation relative to the geoid for the NTGS Mount Peake-Crawford Magnetic, Radiometric and Elevation Survey, NT 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.
