NTGS Victoria Basin Gravity P201582 Elevation GRS80

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This NTGS Victoria Basin Gravity P201582 Elevation GRS80 is elevation data for the NTGS Victoria Basin Gravity Survey (P201582). This survey was acquired under the project No. 201582 for the geological survey of NT. The grid has a cell size of 0.00735 degrees (approximately 800m). This grid contains the ground elevation relative to the geoid for the NTGS Victoria Basin Gravity Survey (P201582). 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。本次的NTGS Victoria Basin Gravity P201582 Elevation GRS80数据集，为北领地地质调查局（NTGS）维多利亚盆地重力勘探（P201582）的配套高程数据。该勘探由编号为201582的项目立项开展，服务于NT的地质调查工作。该网格数据的单元格分辨率为0.00735度（约800米）。本网格涵盖NTGS维多利亚盆地重力勘探（P201582）中相对于大地水准面的地面高程，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。经处理的数据集已由澳大利亚地质调查局（Geoscience Australia, GA）的地球物理学家开展质量核查，以确保GA发布的最终数据满足使用需求。
