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 Boorabbin, Lk Johnstn Fugro multi-client surveys,WA, 1983-85,96,97 survey were acquired in 1987 by the WA Government, and consisted of 50598 line-kilometres of data at a line spacing between 200m 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 Holleton North elevation grid geodetic is elevation data for the Holleton North, WA, 1997. This survey was acquired under the project No. 1077 for the geological survey of WA. The grid has a cell size of 0.001 degrees (approximately 103m). This grid contains the ground elevation relative to the geoid for the Holleton North, WA, 1997. 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.
