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 West Kimberley (Prince Regent - Montague - Charnley), WA,2011 survey were acquired in 2011 by the WA Government, and consisted of 145084 line-kilometres of data at a line spacing between 200m and 800m, and 50m terrain clearance.

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This GSWA Cape Leeuwin Elevation Grid Geodetic is elevation data for the South West (Cape Leeuwin - Collie), WA, 2011. This survey was acquired under the project No. 1244 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 85m). This grid contains the ground elevation relative to the geoid for the South West (Cape Leeuwin - Collie), WA, 2011. 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.
