GSQ Isa Georgetown Block B Qld 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 Isa Georgetown Block B Qld elevation grid geodetic is elevation data for the Isa-Georgetown Block B, QLD, 2000, Prospectivity Plus Initiative. This survey was acquired under the project No. 827 for the geological survey of QLD. The grid has a cell size of 0.00048 degrees (approximately 52m). This grid contains the ground elevation relative to the geoid for the Isa-Georgetown Block B, QLD, 2000, Prospectivity Plus Initiative. 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状测点数据所反映的地形高程变化。本数据集为昆士兰州地质调查局（GSQ）2000年“探矿潜力增强计划（Prospectivity Plus Initiative）”覆盖昆士兰州艾萨-乔治敦B区块的大地测量高程网格数据。本次勘探依托昆士兰州地质调查第827号项目实施。该高程网格的像元尺寸为0.00048度（约合52米）。本网格数据包含2000年“探矿潜力增强计划（Prospectivity Plus Initiative）”覆盖的昆士兰州艾萨-乔治敦B区块相对于大地水准面（Geoid）的地面高程信息。其代表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地球物理学家开展质量核验，以确保GA发布的最终数据符合使用需求。
