GSWA Complete South Yilgarn Elevation Merged 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 Complete South Yilgarn Elevation Merged Grid Geodetic is elevation data for the Complete Southern Yilgarn merge, 2004-2005. This survey was acquired under the project No. 1339 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 85m). This grid contains the ground elevation relative to the geoid for the Complete Southern Yilgarn merge, 2004-2005. 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GSWA（Geological Survey of Western Australia，西澳大利亚地质调查局）完整南伊尔冈合并高程大地测量网格数据集，为2004-2005年完成的南伊尔冈区域合并高程数据。本次勘探依托西澳大利亚州地质调查局第1339号项目开展。该网格的单元尺寸为0.00083度（约85米）。该网格包含2004-2005年南伊尔冈合并区域内相对于大地水准面的地面高程数据，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。经处理的数据已由GA（Geoscience Australia，澳大利亚地球科学局）地球物理学家开展质量核验，确保GA发布的最终数据符合使用需求。
