GSNSW Exploration NSW Area B 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 Exploration NSW Area B Darling Basin elevation grid geodetic is elevation data for the NSW DMR, Discovery 2000, 1994-95, AREA B, Darling Basin. This survey was acquired under the project No. 732 for the geological survey of NSW. The grid has a cell size of 0.00097 degrees (approximately 100m). This grid contains the ground elevation relative to the geoid for the NSW DMR, Discovery 2000, 1994-95, AREA B, Darling Basin. 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。本次提供的GSNSW勘探新南威尔士州（NSW）B区达令盆地（Darling Basin）大地测量高程网格数据，对应NSW DMR、2000年勘探项目（Discovery 2000）1994-1995年度的AREA B区域。本次勘探依托新南威尔士州地质调查局第732号项目开展。该高程网格的单元尺寸为0.00097度（约合100米）。本网格存储了对应上述1994-1995年Discovery 2000项目NSW DMR的达令盆地B区相对于大地水准面（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。经处理的数据已由澳大利亚地球科学局（GA）的地球物理学家完成质量核验，以确保GA发布的最终数据符合使用需求。
