Abstract

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 South Yilgarn merge, 1987-2005 survey were acquired in 1987 by the WA Government, and consisted of 392575 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.

Lineage

This GSWA South Yilgarn merged and levelled, elevation line data is an airborne-derived elevation data for the South Yilgarn merge, 1987-2005. The survey was acquired under the project No. 1338 for the geological survey of WA. A total of 392575 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance were acquired during this survey. 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). Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). This Index is also available online at http://pid.geoscience.gov.au/dataset/79134. Reference: Percival, P.J., 2014. Index of airborne geophysical surveys (Fourteenth Edition).
