Kidson Area B, WA, 1996 (P771), 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 Kidson Areas A & B, WA, 1996 survey were acquired in 1996 by the WA Government, and consisted of 128005 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。本次测量中，为支撑航空磁测与放射性测量数据采集所使用的高度计及全球定位系统（Global Positioning System, GPS）传感器，被用于计算获取高程数据。该高程为相对于澳大利亚高程基准GDA94（AUSGEOID09）的海拔高度。经处理的高程数据将由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使用需求。本测线数据集源自1996年西澳大利亚州（WA）基德森A区与B区的测量项目，由西澳大利亚州政府于1996年采集完成，涵盖总长度达128005线千米的测线数据，测线间距为400米，飞行离地高度为60米。
