Geophysical Acquisition & Processing Section

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 Broken Hill N.S.W, 1994 survey were acquired in 1994 by the NSW Government, and consisted of 56310 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.

Lineage

This Broken Hill N.S.W, 1994 (P617), elevation line data is an airborne-derived elevation data for the Broken Hill N.S.W, 1994. The survey was acquired under the project No. 617 for the geological survey of NSW. A total of 56310 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).
