NTData (digital geology of the Northern Territory), Frew 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AGSO与北领地地质调查局（NTGS）编制的《澳大利亚1:250 000地质系列图》印刷图件所承载信息的数字化再现。该数据集采用分幅格式，并非无缝拼接的整体图件，但已在可行范围内完成了基础的图幅接边处理。所有图幅均遵循澳大利亚标准1:250 000分幅规则进行排布。完整数据集包含覆盖北领地的共计90幅图幅。
