NTData (digital geology of the Northern Territory), Hay River

These data are a digital representation of information depicted on printed maps from the Australia 1:250 000 Geological Series produced by AGSO and the Northern Territory Geological Survey (NTGS) between 1963 and 1998. The data are in a tiled format and are not seamless, although basic edgematching has been done where possible. Tiles are arranged according to the standard Australian 1:250 000 sheet breakup. The complete dataset is comprised of the 90 tiles covering the Northern Territory.

本数据集为1963年至1998年间，由澳大利亚地质调查局（AGSO）与北领地地质调查局（Northern Territory Geological Survey, NTGS）编制的《澳大利亚1:250 000地质系列图》印刷版地图所载信息的数字化表征。该数据采用分幅格式，并非无缝拼接数据，但已在可行范围内完成了基础图幅接边处理。所有分幅均遵循澳大利亚标准1:250 000比例尺图幅分幅规则排布。完整数据集包含覆盖北领地的90幅分幅数据。
