GSNSW Southern Darling Basin 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 GSNSW Southern Darling Basin elevation grid geodetic is elevation data for the Southern Darling Basin Airborne Survey, NSW, 2005. This survey was acquired under the project No. 1104 for the geological survey of NSW. The grid has a cell size of 0.00082 degrees (approximately 84m). This grid contains the ground elevation relative to the geoid for the Southern Darling Basin Airborne Survey, NSW, 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GSNSW南达令盆地大地测量高程格网数据集，为2005年新南威尔士州（New South Wales，NSW）南达令盆地航空勘探所用的高程数据。该勘探数据隶属于新南威尔士州地质调查局编号为1104的地质勘探项目。该格网的单元格尺寸为0.00082度（约84米）。本格网包含2005年新南威尔士州南达令盆地航空勘探的、相对于大地水准面（geoid）的地面高程数据，即地球表面某点位至大地水准面的垂直距离。数据单位为米。经处理的数据已由澳大利亚地质调查局（Geoscience Australia，GA）地球物理学家开展质量核查，以确保该局发布的最终数据符合使用要求。
