NTData (digital geology of the Northern Territory), Napperby

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（Australian Geological Survey Organisation, 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》印刷地图所载信息的数字化处理成果。该数据采用分幅格式，并非无缝拼接的数据集，但已在可行范围内完成了基础的图幅接边处理。所有图幅均按照澳大利亚标准1:250 000比例尺地图分幅规则进行排布。覆盖北领地的完整数据集共计90幅分幅图。
