GSQ Hodgkinson 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 Hodgkinson Georgetown Block B Qld elevation grid geodetic is elevation data for the Hodgkinson-Georgetown Block B, QLD, 1999, Prospectivity Plus Init.. This survey was acquired under the project No. 798 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 Hodgkinson-Georgetown Block B, QLD, 1999, Prospectivity Plus Init.. 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GSQ Hodgkinson Georgetown Block B昆士兰州大地测量高程网格，对应1999年昆士兰州Hodgkinson-Georgetown Block B区域Prospectivity Plus Init.项目的高程数据。该勘探数据依托昆士兰州地质调查局第798号项目采集完成。该网格的单元尺寸为0.00048度（约52米）。此网格包含1999年昆士兰州Hodgkinson-Georgetown Block B区域Prospectivity Plus Init.项目的、相对于大地水准面的地面高程数据，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。
