    Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Barlee Jackson elevation grid geodetic is elevation data for the Barlee, Jackson, WA, 1997. This survey was acquired under the project No. 696 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 86m). This grid contains the ground elevation relative to the geoid for the Barlee, Jackson, WA, 1997. 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.

    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 Duketon, WA, 1994 survey were acquired in 1994 by the WA Government, and consisted of 47160 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 GSNSW Exploration NSW Area P Narrabri elevation grid geodetic is elevation data for the NSW DMR, Discovery 2000, AREA P, NARRABRI, NSW 2000. This survey was acquired under the project No. 753 for the geological survey of NSW. The grid has a cell size of 0.00096 degrees (approximately 100m). This grid contains the ground elevation relative to the geoid for the NSW DMR, Discovery 2000, AREA P, NARRABRI, NSW 2000. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters.

  • GA acts as a portal for all State geophysical datasets with the exception of South Australia. The data is located in the Geophysical Archive Data Delivery System (GADDS) and also mirrored on the externally located GA website. An internal link to the data is: \\Marl\export\jet\3\data (GA specific data is located here and State data is further segregated into folders). OEMD adds new survey datasets to GADDS as they become available. Each State Government requires a different license statement (refer to Licence Details). The height component of these surveys is acquired using radar altimetry.
