Prince Regent, Camden Sound, Montague Sound, WA, 1994 (P614), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. These line dataset from the Prince Regent, Camden Sound, Montague Sound, WA, 1994 survey were acquired in 1994 by the WA Government, and consisted of 61497 line-kilometres of data at 800m line spacing and 100m terrain clearance.

数字高程模型（Digital Elevation Model）表征已知高程点之间的地表地形。本次高程数据由同一次航空磁测与放射性航测任务中所使用的高度计及全球定位系统（Global Positioning System, GPS）传感器计算生成。该高程为相对于澳大利亚高程基准面GDA94（AUSGEOID09）的海拔高度。经处理的高程数据已由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。这套源自西澳大利亚州雷金特王子海峡、卡姆登湾及蒙塔古海峡1994年航次的测线数据集，由西澳大利亚州政府于1994年采集，包含总长度达61497线公里的测线数据，测线间距为800米，航测地形离地高度为100米。
