GSNSW Exploration NSW Area I Albury 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 I Albury elevation grid geodetic is elevation data for the NSW DMR, Discovery 2000, 1994-95, AREA I, Albury. This survey was acquired under the project No. 739 for the geological survey of NSW. The grid has a cell size of 0.00049 degrees (approximately 50m). This grid contains the ground elevation relative to the geoid for the NSW DMR, Discovery 2000, 1994-95, AREA I, Albury. 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状分布数据所反映的地形高程变化。本GSNSW勘探项目的新南威尔士州（NSW）区域I奥尔伯里（Albury）大地测量高程格网，对应NSW DMR 1994-1995年Discovery 2000项目的奥尔伯里区域I高程数据。该勘探数据为新南威尔士州地质调查第739号项目采集所得。该格网的单元尺寸为0.00049度（约50米）。本格网包含对应NSW DMR、1994-1995年Discovery 2000项目奥尔伯里区域I的相对大地水准面（geoid）地面高程数据，即地球表面某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澳大利亚地质科学局（GA）地球物理学家开展质量核查，以确保GA发布的最终数据符合使用需求。
