Gravity Anomaly image 2010 - HSI colour

Hue-Saturation-Intensity (HSI) colour image of the national Gravity Anomaly grid, 2010. This image is made from a grid that represents gravity anomalies of the Australian region. The grid combines accurate onshore gravity measurements, with satellite data over the offshore region. The cell values represent simple Bouguer anomalies at a density of 2.67 tonnes per cubic metre onshore and free-air anomalies offshore. The grid cell size is 0.5 minutes of arc, which is equivalent to about 800 metres.2010年国家重力异常格网的色相-饱和度-明度（Hue-Saturation-Intensity, HSI）彩色图像。该图像基于表征澳大利亚区域重力异常的格网数据生成，此格网融合了高精度陆上重力测量数据与覆盖近海区域的卫星观测资料。格网单元的数值对应如下：陆上区域采用密度为2.67吨/立方米的简单布格异常（simple Bouguer anomalies），近海区域则采用自由空气异常（free-air anomalies）。格网单元尺寸为0.5角分，约合800米。
