Cobar P5009 EXT 3 digital elevation model radar grid

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Cobar P5009 EXT 3 digital elevation model radar grid is elevation data for the Cobar Magnetic and Radiometric Survey, 2021. This survey was acquired under the project No. 5009 for the geological survey of NSW. The grid has a cell size of 0.00039074 degrees (approximately 40m). This grid contains the ground elevation relative to the geoid for the Cobar Magnetic and Radiometric Survey, 2021. 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起伏变化。本次Cobar P5009 EXT 3数字高程模型雷达网格数据，为2021年科巴磁法与放射性勘探（Cobar Magnetic and Radiometric Survey）项目的高程数据。该勘探是在新南威尔士州（New South Wales）编号为5009的地质勘探项目框架下实施的。该网格的像元尺寸为0.00039074度（约40米）。该网格包含2021年科巴磁法与放射性勘探项目中、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。经澳大利亚地质调查局（Geoscience Australia, GA）的地球物理学家对处理后的数据开展质量核查，以确保GA发布的最终数据满足实际使用要求。
