Goulburn, NSW, 1996 (P650), 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 Goulburn, NSW, 1996 survey were acquired in 1996 by the NSW Government, and consisted of 69424 line-kilometres of data at 250m line spacing and 80m 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。该高程数据由本次航空磁测与放射性测量作业中所搭载的高度计及全球定位系统（Global Positioning System, GPS）传感器计算得到。本次所采用的高程为相对于澳大利亚高程基准面GDA94（AUSGEOID09）的高度值。经处理的高程数据已由澳大利亚地质科学局（Geoscience Australia, GA）的地球物理学家开展质量核验，以确保该局发布的最终数据满足使用需求。这套1996年采集的新南威尔士州古尔本（Goulburn, NSW）测线数据集由新南威尔士州政府于1996年获取，共包含69424线公里的测量数据，测线布设间距为250米，飞行作业的地形离地高度为80米。
