West Musgrave Gravity Survey 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 West Musgrave Gravity Survey Elevation Grid geodetic is elevation data for the West Musgrave Gravity 2008 WA (P200860). This survey was acquired under the project No. 200860 for the geological survey of WA. The grid has a cell size of 0.0046 degrees (approximately 485m). This grid contains the ground elevation relative to the geoid for the West Musgrave Gravity 2008 WA (P200860). 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。本数据集为西马斯格雷夫重力勘探高程大地测量格网，对应西澳大利亚州（Western Australia, WA）2008年西马斯格雷夫重力勘探项目（P200860）的高程数据。本次勘探以项目编号200860立项，用于西澳大利亚州的地质调查工作。该格网的单元格尺寸为0.0046度（约合485米）。本格网包含西澳大利亚州2008年西马斯格雷夫重力勘探（P200860）区域内相对于大地水准面（geoid）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。经处理的数据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。
