Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This National Gravity Compilation 2019 ground elevation geoid image (hillshade HSI) is elevation of the observation surface for the 2019 Australian National Gravity Grids A series (Lane et al., 2020a) relative to the geoid vertical datum. These data are part of the project No. 202008. The ground surface data were derived from SRTM data with 3 second grid cell size. The grid used to produce this image has a cell size of 0.00417 degrees (approximately 435m). 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.
