AlbanyFraserNth GroundElevation geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This AlbanyFraserNth GroundElevation geodetic is elevation data for the Albany Fraser Gravity Survey (P201062). This survey was acquired under the project No. 201062 for the geological survey of WA. The grid has a cell size of 0.005 degrees (approximately 519m). This grid contains the ground elevation relative to the geoid for the Albany Fraser Gravity Survey (P201062). 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。本次发布的奥尔巴尼-弗雷泽北段地面高程测地数据集（AlbanyFraserNth GroundElevation）为奥尔巴尼-弗雷泽重力勘探（P201062）的配套高程数据。该勘探项目编号为201062，服务于西澳大利亚州（Western Australia, WA）的地质调查工作。该栅格数据的单元尺寸为0.005度（约合519米），包含奥尔巴尼-弗雷泽重力勘探（P201062）区域内相对于大地水准面（geoid）的地面高程信息，即地球表面某点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调查局（Geoscience Australia, GA）的地球物理学家开展质量核查，以确保该局发布的最终数据符合使用需求。
