Northeast Pilbara GIS teaching package (byte data and real data grids)

Outcrop geology was obtained directly from the following 1:250 000 map sheets: Marble Bar, Nullagine, Port Hedland and Yarrie. This dataset consists of both raster and vector data. Raster data which is unsigned 8 bit integer, can be viewed in Arc/Info, ArcView, MapInfo, ERMapper, ERViewer and ArcExplorer. Raster data which is 4 byte real data, can only be viewed and manipulated with an image processing package such as ERMapper.

露头地质数据直接源自以下1:250 000比例尺图幅：Marble Bar、Nullagine、Port Hedland及Yarrie。本数据集包含栅格数据与矢量数据两类。无符号8位整数型栅格数据可通过Arc/Info、ArcView、MapInfo、ERMapper、ERViewer及ArcExplorer等软件查看；4字节实型栅格数据仅可通过ERMapper等图像处理软件进行查看与操作。
