GSWA Trayning 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 GSWA Trayning elevation grid geodetic is elevation data for the Trayning, WA, 1997. This survey was acquired under the project No. 1068 for the geological survey of WA. The grid has a cell size of 0.00035 degrees (approximately 36m). This grid contains the ground elevation relative to the geoid for the Trayning, WA, 1997. 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）记录了由地球物理勘探过程中采集并经处理的点位或线状数据反演得到的地形高程变化。本GSWA特雷宁大地测量高程网格为1997年西澳大利亚州特雷宁（Trayning, WA）区域的高程数据。本次勘探系为西澳大利亚州地质调查项目第1068号所采集。该网格的单元尺寸为0.00035度（约合36米）。本网格包含1997年西澳大利亚州特雷宁区域相对于大地水准面（geoid）的地面高程信息，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。经处理的数据已由澳大利亚地球科学局（Geoscience Australia, GA）的地球物理学家完成质量核查，以确保GA发布的最终数据符合使用需求。
