9 Second DEM Derived Streams v1.1.3

The 9 second DEM derived streams are a a fully connected and directed stream network produced in rastor and vector fomats by Australian National University. This product is the raster format, for the the vector product please refer to the Bureau of Meterology's Geofabric Website (http://www.bom.gov.au/water/geofabric/index.shtml). It is built upon the representation of surface drainage patterns provided by the GEODATA national 9 second Digital Elevation Model (DEM) Version 3 (ANU Fenner School of Environment and Society and Geoscience Australia, 2008).

由澳大利亚国立大学（Australian National University）生成的9秒分辨率数字高程模型（Digital Elevation Model，DEM）衍生水系，是一套全连通且带流向属性的有向水系网络，以栅格（raster）与矢量（vector）两种格式产出。本产品为栅格格式版本，矢量格式版本请参阅澳大利亚气象局（Bureau of Meteorology）的Geofabric官网：http://www.bom.gov.au/water/geofabric/index.shtml。该数据集基于GEODATA国家9秒分辨率数字高程模型第3版（ANU Fenner环境与社会学院及澳大利亚地质科学局，2008年）提供的地表径流格局表征数据构建。
