GSQ East Isa 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 GSQ East Isa North elevation grid geodetic is elevation data for the East Mount Isa - North, Qld, 2007. This survey was acquired under the project No. 1144 for the geological survey of QLD. The grid has a cell size of 0.00083 degrees (approximately 89m). This grid contains the ground elevation relative to the geoid for the East Mount Isa - North, Qld, 2007. 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线址数据所反映的地形高程变化。本GSQ东艾萨北部大地测量高程网格数据，对应2007年昆士兰州（Qld）东芒特艾萨北部区域的高程数据集。本次勘探依托昆士兰州地质调查第1144号项目开展。该网格的单元尺寸为0.00083度（约89米）。该网格包含2007年昆士兰州东芒特艾萨北部区域相对于大地水准面（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。经处理的数据已由GA地球物理学家完成质量核验，以确保GA发布的最终数据满足使用需求。
