Childara - elevation line data

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 Childara Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey were acquired in 2017 by the SA Government, and consisted of 135047 line-kilometres of data at 200m line spacing and 60m terrain clearance.
