Burakin Mt Marshall Lake Hillman Goomalling 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 Burakin Mt Marshall Lake Hillman Goomalling elevation grid geodetic is elevation data for the Burakin-Mt Marshall-Lake Hillman-Goomalling merge, 1997-2003. This survey was acquired under the project No. 1358 for the geological survey of WA. The grid has a cell size of 0.00042 degrees (approximately 43m). This grid contains the ground elevation relative to the geoid for the Burakin-Mt Marshall-Lake Hillman-Goomalling merge, 1997-2003. 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后处理的点位、测线实测数据所反映的地形高程变化。本布拉金-马绍尔山-希尔曼湖-古马林大地测量高程网格，对应1997-2003年布拉金-马绍尔山-希尔曼湖-古马林合并勘探区域的高程数据。本次勘探系西澳大利亚州（Western Australia，简称WA）编号为1358的地质调查项目作业内容。该网格的单元分辨率为0.00042度（约合43米）。该网格包含1997-2003年布拉金-马绍尔山-希尔曼湖-古马林合并区域内、相对于大地水准面（geoid）的地面高程数据。其表征地球表面任意点位至大地水准面的垂直距离。数据单位为米。经后处理的数据已由澳大利亚地质调查局（Geoscience Australia，简称GA）地球物理学家完成质量核验，以确保GA发布的最终数据完全适配实际应用需求。
