Seemore, WA, 2009 (Eucla Basin 1) (P1208), 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 Seemore, WA, 2009 (Eucla Basin 1) survey were acquired in 2009 by the WA Government, and consisted of 105710 line-kilometres of data at 200m line spacing and 50m 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。本次高程数据通过同次航空磁测与放射性测量所使用的高度计及全球定位系统（GPS）传感器计算得到。该高程为相对于澳大利亚高程基准GDA94（AUSGEOID09）的海拔高度。经处理后的高程数据由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适用用途要求。本次测线数据集源自2009年西澳大利亚州希莫尔（Seemore）地区的尤克拉盆地1号测量项目，由西澳大利亚州政府于2009年采集，包含总长105710测线千米的数据，测线间距为200米，飞行离地高度为50米。
