Paterson Central, WA, 2005 (P1092), 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 Paterson Central, WA, 2005 survey were acquired in 2005 by the WA Government, and consisted of 94391 line-kilometres of data at 400m line spacing and 60m 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。本数据集的高程数据由本次航磁与放射性测量作业所使用的机载高度计及全球定位系统（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发布的最终数据满足应用需求。本次2005年西澳大利亚州（WA）帕特森中央（Paterson Central）航次的航线数据集由西澳州政府于2005年采集，数据总测线里程达94391航线公里，测线间距为400米，航测作业离地高度为60米。
