SA Gravity Survey 2002A11 (P200242), 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 2002A11 (P200242) contains a total of 20 point data values acquired at a spacing of 1000 metres. The data is located in SA and were acquired in 2002, under project No. 200242 for None.

重力数据用于监测地球表面下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准流程进行处理，以确保记录得到的响应仅源自地下岩石的影响。经处理得到的数据集可通过解译，揭示地下地质构造。经处理的数据会由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用需求。本次南澳大利亚州（South Australia，简称SA）重力测量项目2002A11（编号P200242）共包含20组测点数据，测点间距为1000米。该数据集的采集点位位于SA，采集于2002年，隶属于编号为200242的项目，委托方信息未公开。
