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 Adavale Qld, (Geomap 2005) GDI 1997/1998 survey were acquired in 1998 by the QLD Government, and consisted of 174490 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This GSQ Ayr St Lawrence Qld elevation grid geodetic is elevation data for the Ayr-St Lawrence, QLD, AIRDATA, 1996. This survey was acquired under the project No. 796 for the geological survey of QLD. The grid has a cell size of 0.00096 degrees (approximately 103m). This grid contains the ground elevation relative to the geoid for the Ayr-St Lawrence, QLD, AIRDATA, 1996. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
