Abstract
Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Tanami NS 1D - ground elevation geoid grid (radar) is elevation data for the NTGS Tanami NS 1D Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018. This survey was acquired under the project No. 1312 for the geological survey of NT. The grid has a cell size of 0.00018 degrees (approximately 20m). This grid contains the ground elevation relative to the geoid for the NTGS Tanami NS 1D Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018. 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.

This Tanami NS 1D - ground elevation geoid grid (radar) is elevation data for the NTGS Tanami NS 1D Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 acquired under the project No. 1312 for the geological survey of NT. The grid has a cell size of 0.00018 degrees (approximately 20m). This grid contains the ground elevation values relative to the geoid for the NTGS Tanami NS 1D Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018. 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 are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose.
