North Central Tasmania elevation grid (south) geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This North Central Tasmania elevation grid (south) geodetic is elevation data for the North Central Tasmania, Tas, 1999. This survey was acquired under the project No. 699 for the geological survey of TAS. The grid has a cell size of 0.00042 degrees (approximately 40m). This grid contains the ground elevation relative to the geoid for the North Central Tasmania, Tas, 1999. 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类原始数据所反映的地形高程起伏情况。本数据集为采用南部大地基准的塔斯马尼亚州中北部高程网格数据，对应1999年塔斯马尼亚州中北部区域的高程信息。本次勘探是为开展塔斯马尼亚州地质调查，在第699号项目框架下采集完成的。该网格的单元尺寸为0.00042度（约合40米）。本网格数据记录了1999年塔斯马尼亚州中北部地区相对于大地水准面的地面高程。其数值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。经处理后的数据集已由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用需求。
