Murchison 1 (Murgoo), WA, 2011 (P1239), 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 Murchison 1 (Murgoo), WA, 2011 survey were acquired in 2011 by the WA Government, and consisted of 131101 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。本次测量中为配套航空磁测与放射性测量工作而使用的高度计及全球定位系统（Global Positioning System, GPS）传感器，解算了本次的高程数据。该高程以澳大利亚大地基准GDA94（AUSGEOID09）为参考基准。经处理的高程数据将由澳大利亚地球科学局（Geoscience Australia, GA）的地球物理学家开展质量核查，以确保该局对外发布的最终数据符合使用需求。2011年西澳大利亚州（WA）默奇森1号（穆尔古）测量项目产出的该套测线数据集，由西澳大利亚州政府于2011年采集完成，总测线长度达131101线公里，测线间距为200米，航测地形离地高度为50米。
