Tanami EW 5N - ground elevation geoid grid (radar)

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Tanami EW 5N - ground elevation geoid grid (radar) is elevation data for the NTGS Tanami EW 5N Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018. This survey was acquired under the project No. 1312 for the geological survey of NT. The grid has a cell size of 0.00018 degrees (approximately 20m). This grid contains the ground elevation relative to the geoid for the NTGS Tanami EW 5N Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018. 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线位数据所反映的地形高程变化。本塔纳米EW 5N地面高程似大地水准面格网（雷达），为2018年北领地（NT）北领地地质调查局（NTGS）塔纳米EW 5N区域详细航空磁测放射性与数字高程测量项目的高程数据成果。该测量工作由北领地地质调查项目编号1312立项实施。该格网的单元尺寸为0.00018度（约20米）。本格网包含2018年北领地塔纳米EW 5N区域详细航空磁测放射性与数字高程测量中相对于似大地水准面的地面高程数据，其数值代表地球表面任意点位至似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（GA）地球物理学家完成质量核验，以确保该局发布的最终数据满足使用需求。
