King Island, Tas, 2001 (WTRMP Area A) (P822), 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 King Island, Tas, 2001 (WTRMP Area A) survey were acquired in 2001 by the TAS Government, and consisted of 8633 line-kilometres of data at 200m line spacing and 80m terrain clearance.

数字高程模型（Digital Elevation Model）表示已知高程点之间的地表地形。高程数据通过高度计和全球定位系统（GPS）传感器计算得出，这些传感器用于同一次测量中的航空磁测与辐射测量数据采集。高程为相对于澳大利亚高程基准GDA94（AUSGEOID09）的高度。经处理的高程数据由澳大利亚地球科学局（GA）的地球物理学家进行质量检查，以确保GA发布的最终数据符合使用要求。
这些来自塔斯马尼亚州（Tas）金岛2001年（WTRMP A区）测量的线数据集由塔斯马尼亚州政府于2001年获取，包含8633线公里的数据，线间距为200米，地形净空高度为80米。
