GSQ Croydon 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 Croydon elevation grid geodetic is elevation data for the Croydon, Qld, 2007. This survey was acquired under the project No. 1146 for the geological survey of QLD. The grid has a cell size of 0.00083 degrees (approximately 90m). This grid contains the ground elevation relative to the geoid for the Croydon, 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测线数据所反映的地形高程变化。本GSQ克罗伊登大地测量高程网格数据集为2007年昆士兰州（QLD）克罗伊登地区的高程数据。该勘探工作依托第1146号项目为QLD地质调查局开展，相关数据由其采集获取。该网格的单元尺寸为0.00083度（约90米），包含2007年QLD克罗伊登地区相对于大地水准面（geoid）的地面高程信息，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。经处理后的数据集已由GA地球物理学家完成质量核验，以确保GA发布的最终数据符合使用需求。
