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 Dumbleyung (SWCC), WA, 2008 survey were acquired in 2008 by the WA Government, and consisted of 75805 line-kilometres of data at a line spacing between 100m and 400m, 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 GSWA Paterson Central elevation grid geodetic is elevation data for the Paterson Central, WA, 2005. This survey was acquired under the project No. 1092 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 89m). This grid contains the ground elevation relative to the geoid for the Paterson Central, WA, 2005. 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.
