GSWA East Yilgarn 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 East Yilgarn Elevation Grid Geodetic is elevation data for the East Yilgarn, WA, 2005. This survey was acquired under the project No. 1097 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 86m). This grid contains the ground elevation relative to the geoid for the East Yilgarn, WA, 2005. 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的经处理点位或测线数据所反映的地形高程起伏。本数据集为GSWA东伊尔加尔恩大地测量高程网格（GSWA East Yilgarn Elevation Grid Geodetic），系2005年西澳大利亚州东伊尔加尔恩区域的高程数据。该套数据由西澳大利亚州编号为1097的地质调查项目负责采集。该格网的分辨率为0.00083度（约86米）。本格网包含2005年西澳大利亚州东伊尔加尔恩区域相对于大地水准面（geoid）的地面高程数据，其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GA地球物理学家对处理后的数据开展质量核查，以确保GA发布的最终数据符合使用需求。
