GSWA Prince Regent Montague Elevation Grid Geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This GSWA Prince Regent Montague Elevation Grid Geodetic is elevation data for the West Kimberley (Prince Regent - Montague - Charnley), WA,2011. This survey was acquired under the project No. 1236 for the geological survey of WA. The grid has a cell size of 0.00167 degrees (approximately 182m). This grid contains the ground elevation relative to the geoid for the West Kimberley (Prince Regent - Montague - Charnley), WA,2011. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

数字高程数据（Digital Elevation Data）用于记录地球物理勘探过程中采集并经处理的点位或线状定位数据所反映的地形高程变化。本数据集为GSWA普雷斯顿-蒙塔古高程大地测量网格，对应2011年西澳大利亚州（WA）西金伯利地区（普雷斯顿-蒙塔古-查恩利）的高程数据。本次勘探以第1236号项目为依托，由西澳大利亚州地质调查局开展采集。该网格的单元尺寸为0.00167度（约182米），包含上述区域范围内相对于大地水准面（geoid）的地面高程数据，其代表地球表面某点位至大地水准面的垂直距离，数据单位为米。经处理后的数据集已由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需求。
