SA Gravity Survey 1998A5 (P199855), 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 1998A5 (P199855) contains a total of 107 point data values acquired at a spacing of 65 metres. The data is located in SA and were acquired in 1998, under project No. 199855 for None.

重力数据用于监测地球地表下方岩石密度变化所引发的微小重力变化。所采集的数据将采用标准化流程进行处理，以确保记录得到的重力响应仅由地下岩石引起。经处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据将由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要求。本次SA重力测量1998A5（编号P199855）共包含107组测点数据，测点间距为65米。该数据采集于SA地区，采集时间为1998年，隶属于项目编号199855，委托方信息未注明。
