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 Widgiemooltha North, WA, 2013 survey were acquired in 2013 by the WA Government, and consisted of 92768 line-kilometres of data at 100m line spacing and 50m terrain clearance.

Lineage
This Widgiemooltha North, WA, 2013 (P1259), elevation line data is an airborne-derived elevation data for the Widgiemooltha North, WA, 2013. The survey was acquired under the project No. 1259 for the geological survey of WA. A total of 92768 line-kilometres of data at a line spacing of 100m and 50m 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 airborne of 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).
