GSWA Hyden North 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 GSWA Hyden North elevation grid geodetic is elevation data for the Hyden North, WA, 1997. This survey was acquired under the project No. 1078 for the geological survey of WA. The grid has a cell size of 0.001 degrees (approximately 102m). This grid contains the ground elevation relative to the geoid for the Hyden North, WA, 1997. 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GSWA海登北大地测量高程格网数据集为1997年西澳大利亚州（WA）海登北地区的高程数据。本次勘探为西澳大利亚州地质调查项目第1078号项下的采集任务。该格网的单元格分辨率为0.001度（约合102米）。本格网包含1997年西澳大利亚州海登北地区相对于大地水准面的地面高程数据，其表征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GA地球物理学家对处理后的数据开展质量核查，确保GA发布的最终数据符合使用需求。
