Marble Bar 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 Marble Bar elevation grid geodetic is elevation data for the Marble Bar, WA, 1996. This survey was acquired under the project No. 649 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 89m). This grid contains the ground elevation relative to the geoid for the Marble Bar, WA, 1996. 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地形高程变化。本马布尔巴大地测量高程格网数据为1996年西澳大利亚州（Western Australia，简称WA）马布尔巴地区的高程数据。本次勘探系为开展西澳大利亚州地质调查，以第649号项目编号实施采集。该格网的单元尺寸为0.00083度（约合89米）。本格网数据包含1996年西澳大利亚州马布尔巴地区相对于大地水准面的地面高程信息，其数值代表地球表面某点位至大地水准面的垂直距离。数据单位为米。经西澳地质调查局（Geological Survey of Western Australia，简称GA）的地球物理学家对处理后的数据开展质量检查，以确保GA发布的最终数据符合使用需求。
