Full description

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.
This National Mapping Helicopter Gravity, Height Survey (P196211) contains a total of 633 point data values acquired at a spacing of 11265 metres. The data is located in NSW, QLD and were acquired in 1962, under project No. 196211 for Australian Survey Office (National Mapping); Bureau of Mineral Resources (BMR).
