NTData (digital geology of the Northern Territory), Highland Rocks

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.本数据集是对1963年至1998年间由澳大利亚地质调查组织（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1:25万地质图系列》印刷地图所承载信息的数字化复刻。该数据采用分幅格式，并非无缝拼接，但已在可行范围内完成基础边缘匹配处理。所有分幅均按照澳大利亚标准1:25万图幅划分规则进行排布。完整数据集包含覆盖北领地的90幅分幅数据。
