Isa-Georgetown Block A,QLD, 2000, Prospectivity Plus Initiative (P826), 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 Isa-Georgetown Block A,QLD, 2000, Prospectivity Plus Initiative survey were acquired in 2000 by the QLD Government, and consisted of 34868 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）表示已知高程点之间的地表地形。高程数据是利用高度计和全球定位系统（GPS）传感器计算得出的，这些传感器是为同一调查中的航空磁测和辐射测量数据服务的。高程是相对于澳大利亚高程基准GDA94（AUSGEOID09）的高度。处理后的高程数据由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预期用途。

这些来自2000年昆士兰州Isa-Georgetown A区块“Prospectivity Plus Initiative”调查的线数据集由昆士兰州政府于2000年获取，包含34868线公里的数据，线间距为200米至400米，地形净空高度为80米。
