GSSA Andamooka Elevation laser grid geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This GSSA Andamooka Elevation laser grid geodetic is elevation data for the Andamooka Airborne Magnetic Radiometric and DEM Survey, 2017. This survey was acquired under the project No. 1282 for the geological survey of SA. The grid has a cell size of 0.00042 degrees (approximately 43m). This grid contains the ground elevation relative to the geoid for the Andamooka Airborne Magnetic Radiometric and DEM Survey, 2017. 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位数据所反映的地形高程变化。南澳地质调查局（Geological Survey of South Australia, GSSA）安达莫卡高程激光网格大地测量数据集，为2017年安达莫卡航空磁辐射测量与数字高程模型（Digital Elevation Model, DEM）调查的高程数据。本次勘探系为开展南澳地质调查，于项目编号1282项下实施。该网格的像元分辨率为0.00042度（约合43米）。本数据集涵盖2017年安达莫卡航空磁辐射测量与DEM调查中相对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。
