Mt Isa E Gravity Complete Bouguer Anomaly 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 Mt Isa E Gravity Complete Bouguer Anomaly geodetic is a complete Bouguer anomaly grid for the Mt Isa Area E Gravity Survey (P200644). This gravity survey was acquired under the project No. 200644 for the geological survey of QLD. The grid has a cell size of 0.0075 degrees (approximately 802m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 6123 gravity stations were acquired to produce this grid.

重力数据用于监测地球表层下方岩石密度变化引发的微小重力场变化。所采集的数据将通过标准流程开展处理，以确保记录得到的响应仅由地下岩石所引发。经处理得到的数据集可通过解译揭示地下地质构造。处理后的数据将由GA地球物理学家进行质量校验，以确保GA发布的最终数据符合使用需求。
本伊萨山东向重力完全布格异常（Complete Bouguer Anomaly）大地测量数据集，是针对伊萨山区域东向重力测量（项目编号P200644）生成的完全布格异常网格。
本次重力测量系为开展昆士兰州地质调查，由项目编号200644资助实施。
该网格的单元尺寸为0.0075度（约合802米）。
数据单位为微米每二次方秒（um/s²），亦称为‘重力单位’，简称gu。
本网格共依托6123个重力测点生成。
