Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Tennant Creek-Mt Isa (TISA) Gravity Surveys, South West McArthur (ground elevation geoid grid) is elevation data for the Tennant Creek-Mt Isa (TISA) Gravity Surveys, South West McArthur Barkley, Northern Territory, 2019. This survey was acquired under the project No. 201901 for the geological survey of NT, QLD. The grid has a cell size of 0.00461 degrees (approximately 500m). This grid contains the ground elevation relative to the geoid for the Tennant Creek-Mt Isa (TISA) Gravity Surveys, South West McArthur Barkley, Northern Territory, 2019. 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.
