Australia Wide AFGN Absolute 2015 (P201590), 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 Australia Wide AFGN Absolute 2015 (P201590) contains a total of 35 point data values acquired at a spacing between 200 and 750 metres. The data is located in ACT, NSW, NT, QLD, SA, TAS, VIC, WA and were acquired in 2015, under project No. 201590 for Geoscience Australia.

重力数据用于捕捉地球表层下方岩石密度变化引发的微小重力变化。所采集的数据将通过标准化流程进行处理，以确保记录的响应仅源于地下岩石的影响。经处理后得到的数据集可用于解译，以揭示地下地质构造。经处理的数据需由澳大利亚地球科学局（Geoscience Australia，GA）的地球物理学家开展质量核查，以确保该局发布的最终数据符合预期使用要求。
本次发布的全澳范围AFGN绝对重力数据集2015版（编号P201590）共计包含35组测点数据，测点间距介于200米至750米之间。该数据集覆盖澳大利亚首都领地（ACT）、新南威尔士州（NSW）、北领地（NT）、昆士兰州（QLD）、南澳大利亚州（SA）、塔斯马尼亚州（TAS）、维多利亚州（VIC）以及西澳大利亚州（WA），于2015年通过编号为201590的项目由澳大利亚地球科学局采集完成。
