MRTAS NW Tasmania 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 MRTAS NW Tasmania elevation grid geodetic is elevation data for the North West Tasmania, Tas, 2001 (WTRMP Area B). This survey was acquired under the project No. 823 for the geological survey of TAS. The grid has a cell size of 0.00042 degrees (approximately 41m). This grid contains the ground elevation relative to the geoid for the North West Tasmania, Tas, 2001 (WTRMP Area B). 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.

数字高程数据记录了地球物理调查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起伏。本MRTAS塔斯马尼亚西北部大地测量高程格网数据，为2001年塔斯马尼亚州西北部（WTRMP B区）的高程数据集。本次勘探由塔斯马尼亚地质调查局依托第823号项目采集完成。该格网的像元尺寸为0.00042度（约41米），包含2001年塔斯马尼亚州西北部（WTRMP B区）相对于大地水准面的地面高程信息，即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。经处理的原始数据已由澳大利亚地球科学局（GA）的地球物理学家完成质量核验，以确保该局发布的最终数据符合实际应用需求。
