Medusa Banks Port Keats 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 Medusa Banks Port Keats elevation grid geodetic is elevation data for the Medusa Banks, Port Keats, WA, 1994. This survey was acquired under the project No. 608 for the geological survey of WA. The grid has a cell size of 0.001 degrees (approximately 109m). This grid contains the ground elevation relative to the geoid for the Medusa Banks, Port Keats, WA, 1994. 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。本次的美杜莎浅滩吉茨港大地测量高程格网数据，为1994年西澳州（WA）吉茨港（Port Keats）美杜莎浅滩（Medusa Banks）区域的高程数据。本次勘探依托西澳州地质调查第608号项目完成采集。该格网的单元尺寸为0.001度（约合109米）。该格网包含1994年西澳州吉茨港美杜莎浅滩区域相对于大地水准面（Geoid）的地面高程信息，其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GA地球物理学家对处理后的数据进行质量核查，以确保GA发布的最终数据满足使用需求。
