GSNSW DPI Jerilderie Oaklands Basin Complete Spherical Cap Bouguer geodetic

Gravity data measure 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 GSNSW DPI Jerilderie Oaklands Basin Complete Spherical Cap Bouguer geodetic is a complete spherical cap Bouguer anomaly grid for the Oaklands Basin - Jerilderie Gravity Survey, 2009, NSW (P200920). This gravity survey was acquired under the project No. 200920 for the geological survey of NSW. The grid has a cell size of 0.0075 degrees (approximately 759m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 2350 gravity stations were acquired to produce this grid.

重力数据用于测量地球表面下方岩石密度变化引发的微小重力变化。所采集的数据需通过标准方法处理，以确保记录的响应仅源于地下岩石。经处理后得到的数据集可通过解译揭示地下地质构造。经处理的重力数据将由澳大利亚地质调查局（Geoscience Australia，GA）的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GSNSW DPI杰里德里（Jerilderie）奥克兰兹盆地（Oaklands Basin）完整球面帽布格大地测量数据集，为2009年新南威尔士州杰里德里重力勘探项目（P200920）针对奥克兰兹盆地生成的完整球面帽布格异常网格。
本次重力勘探为新南威尔士州地质调查项目编号200920的实施内容。
该网格的单元尺寸为0.0075度（约759米）。
数据单位为微米每二次方秒（μm/s²），亦称为‘重力单位（gravity units，gu）’。
本次勘探共采集2350个重力测点以生成该网格。
