Liverpool Plains 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 Liverpool Plains elevation grid geodetic is elevation data for the Liverpool Plains, NSW, 1995. This survey was acquired under the project No. 625 for the geological survey of NSW. The grid has a cell size of 0.00042 degrees (approximately 43m). This grid contains the ground elevation relative to the geoid for the Liverpool Plains, NSW, 1995. 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（Digital Elevation）数据记录了地球物理勘探过程中采集并经处理的点位或测线类原始数据所反映的地形高程变化。本利物浦平原大地测量高程网格为1995年新南威尔士州利物浦平原地区的高程数据。本次勘探依托新南威尔士州地质调查局编号为625的项目开展。该网格的像元分辨率为0.00042度（约43米）。该网格包含1995年新南威尔士州利物浦平原地区相对于大地水准面（geoid）的地面高程信息，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。经处理后的数据集已由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。
