Paterson Bouguer anomaly grid geodetic

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 Paterson Bouguer anomaly grid geodetic is a complete Bouguer anomaly grid for the Paterson - WA Gravity Survey (P4025). This gravity survey was acquired under the project No. 4025 for the geological survey of WA. The grid has a cell size of 0.0037 degrees (approximately 396m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of None gravity stations were acquired to produce this grid.

重力数据用于表征地球表层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化处理流程开展校正，以确保记录的响应仅来源于地下岩石的影响。经处理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。
本帕特森布格异常（Bouguer anomaly）大地测量网格是帕特森-西澳重力测量（P4025）的完整布格异常网格。该重力测量系为西澳地质调查局的第4025号项目所采集。该网格的单元尺寸为0.0037度（约396米）。本数据的单位为微米每二次方秒（μm/s²），亦称作「重力单位」（gravity units）或gu。为生成该网格，共采集了None处重力测点。
