SA Gravity Survey 2003A4 (P200344), gravity point data

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 SA Gravity Survey 2003A4 (P200344) contains a total of 449 point data values acquired at a spacing between 400 and 800 metres. The data is located in SA and were acquired in 2003, under project No. 200344 for None.

重力数据用于测量地球表面以下岩石密度变化引起的重力微小波动。所采集的数据经标准方法处理，以确保记录的响应仅源于地下岩石。处理结果生成的数据集可通过解释揭示地下地质结构。处理后的数据由GA地球物理学家开展质量核查，确保GA发布的最终数据符合用途要求。本次SA重力测量2003A4（P200344）共包含449个点数据值，采集间距为400至800米。数据位于SA区域，于2003年采集，项目编号200344，无特定关联主体。
