Yathong Magnetic Gradient and Radiometric Survey, NSW, 2023, (P5023), ground elevation geoid grid

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Yathong Magnetic Gradient and Radiometric Survey, NSW, 2023, (P5023), ground elevation geoid grid is elevation data for the Yathong airborne magnetic gradient and radiometric survey, 2023. This survey was acquired under the project No. 5023 for the geological survey of NSW. The grid has a cell size of degrees (approximately 40m). This grid contains the ground elevation relative to the geoid for the Yathong airborne magnetic gradient and radiometric survey, 2023. 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。本数据集为2023年新南威尔士州（New South Wales, NSW）亚松磁梯度与放射性勘探项目（编号P5023）的大地水准面地面高程格网数据，对应2023年亚松航空磁梯度与放射性勘探项目的高程成果。该勘探项目隶属于新南威尔士州编号为5023的地质调查项目。该格网的单元格大小为 度（约40米）。本格网包含2023年亚松航空磁梯度与放射性勘探项目中相对于大地水准面的地面高程数据，其表征地球表面某一位置至大地水准面的垂直距离，单位为米。经澳大利亚地质调查局（Geoscience Australia, GA）地球物理学家对处理后的数据开展质量核查，确保该局发布的最终数据满足既定使用需求。
