West Tanami 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 West Tanami elevation grid geodetic is elevation data for the West Tanami, WA, 2002. This survey was acquired under the project No. 862 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 90m). This grid contains the ground elevation relative to the geoid for the West Tanami, WA, 2002. 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）记录了地球物理勘探过程中采集并经处理的点位或测线数据所反映的地形高程变化。本西塔纳米大地测量高程网格数据集为2002年西澳大利亚州（Western Australia，缩写WA）西塔纳米地区的高程数据。本次勘探系为实施西澳大利亚州地质调查，以第862号项目名义采集。该网格的单元尺寸为0.00083度（约合90米）。本网格包含2002年西澳大利亚州西塔纳米地区相对于大地水准面（geoid）的地面高程数据，该高程值代表地球表面任意点位至大地水准面的垂直距离。数据单位为米。经处理的数据已由GA地球物理学家开展质量核查，以确保GA发布的最终数据集符合使用需求。
