SMMSP - MagSpec - St George, Qld, 2001 (P906), 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 SMMSP - MagSpec - St George, Qld, 2001 survey were acquired in 2001 by the QLD Government, and consisted of 61110 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.
