NTData (digital geology of the Northern Territory), McDills

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.

这些数据是1963年至1998年间由AGSO和北领地地质调查局（Northern Territory Geological Survey，NTGS）制作的澳大利亚1:250000地质系列印刷地图上所呈现信息的数字化表示。数据采用分块格式（tiled format），并非无缝衔接，但已在可能的情况下进行了基础边缘匹配（edgematching）。分块按照澳大利亚1:250000标准图幅划分（sheet breakup）规则排列。完整数据集由覆盖北领地的90个分块组成。
