Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Julia Creek elevation grid geodetic is elevation data for the Julia Creek, QLD, 1999. This survey was acquired under the project No. 1000 for the geological survey of QLD. The grid has a cell size of 0.00083 degrees (approximately 90m). This grid contains the ground elevation relative to the geoid for the Julia Creek, QLD, 1999. 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.

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
