Anketell (Detailed), WA, 2002 (P1080), 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 Anketell (Detailed), WA, 2002 survey were acquired in 2002 by the WA Government, and consisted of 23340 line-kilometres of data at 150m line spacing and 25m terrain clearance.

数字高程模型（Digital Elevation Model）用于表征已知高程点之间的地表地形。本次高程数据通过为配合同次航空磁测与放射性测量作业而搭载的高度计及全球定位系统（GPS）传感器计算得到。该高程值以澳大利亚高程基准面GDA94（AUSGEOID09）为参照基准。经处理后的高程数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据符合使用需求。
本次航线数据集源自2002年西澳大利亚州安基泰尔（详细测量）航空调查项目，由西澳大利亚州政府于2002年采集完成，总航线长度达23340千米，航线间距为150米，地形离地高度为25米。
