资源简介：
The AusHydro database provides a seamless surface hydrography layer for Australia at a nominal scale of 1:250, 000. It consists of lines, points and polygons representing natural and man-made features such as water courses, lakes, dams and other waterbodies. The natural water course layer consists of a linear network with a consistent topology that provide directional flow paths through the network for hydrological analysis. This network was used to produce the National 9 second Digital Elevation Model (DEM) of Australia (http://www.ga.gov.au/nmd/products/digidat/dem_9s.jsp). It also provides information on naming, hierarchy and perenniality.
