Hodgkinson-Georgetown Block A, QLD, 1999, Prospectivity Plus Init. (P797), 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 Hodgkinson-Georgetown Block A, QLD, 1999, Prospectivity Plus Init. survey were acquired in 1999 by the QLD Government, and consisted of 93258 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.数字高程模型（Digital Elevation Model）表征已知高程点之间的地表地形。本次高程数据通过同一勘测中用于航空磁测与放射性测量的高度计及全球定位系统（Global Positioning System，GPS）传感器计算得到。该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应用需求。本次测线数据集源自1999年昆士兰州（QLD）霍奇金森-乔治敦A区块"Prospectivity Plus Init."勘测项目，由昆士兰州政府于1999年采集，数据总长度达93258线公里，测线间距为200米至400米，地形离地高度为80米。
