Wangaratta 1:250,000 Infill (P199930), 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 Wangaratta 1:250,000 Infill (P199930) contains a total of 5142 point data values acquired at a spacing between 500 and 1500 metres. The data is located in VIC and were acquired in 1999, under project No. 199930 for None.

重力数据用于测量地球表面以下岩石密度变化所引起的重力微小变化。采集的数据通过标准方法处理，以确保记录的响应仅源于地下岩石。处理结果生成的数据集可通过解释揭示地下地质结构。处理后的数据由GA地球物理学家进行质量检查，以确保GA发布的最终数据符合预期用途。

该旺加拉塔1:250000加密数据集（P199930）共包含5142个点数据值，采集间距介于500至1500米之间。数据位于VIC地区，于1999年在199930号项目下采集，无特定关联方。
