GSNSW Exploration NSW Area K Peel 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 K Peel elevation grid geodetic is elevation data for the NSW DMR, Discovery 2000 Area K, Peel (Inverell,Manilla), NSW, 1998. This survey was acquired under the project No. 740 for the geological survey of NSW. The grid has a cell size of 0.00048 degrees (approximately 50m). This grid contains the ground elevation relative to the geoid for the NSW DMR, Discovery 2000 Area K, Peel (Inverell,Manilla), NSW, 1998. 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及线状测点数据所反映的地形高程变化。本次发布的GSNSW勘探项目新南威尔士州K区域皮尔大地测量高程网格数据，对应1998年新南威尔士州DMR、Discovery 2000项目K区域、皮尔（因弗雷尔、马尼拉）区域的高程数据。本次勘探依托新南威尔士州地质调查局第740号项目开展。该网格的单元尺寸为0.00048度（约50米）。本网格包含1998年新南威尔士州DMR、Discovery 2000项目K区域、皮尔（因弗雷尔、马尼拉）区域的相对大地水准面的地面高程数据，其表征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地球物理学家完成质量核查，以确保GA发布的最终数据符合使用需求。
