National Surface Water Information

A core information requirement for managing Australia’s water resources is knowledge of the spatial location, relationships and characteristics of the hydrological features: the catchments, streams, aquifers, storages, wetlands and man-made structures that make up the hydrological system. In late 2008, the Bureau of Meteorology (BoM), in partnership with Geoscience Australia, CSIRO and the Australian National University (ANU) commenced the development of the Australian Hydrological Geospatial Fabric (Geofabric).

The Geofabric is being developed to underpin the Australian Water Resources Information System (AWRIS) within a single, consistent, national geospatial framework for hydrological features.

Geoscience Australia’s role in the Geofabric is providing the best available national topographic spatial data for surface water features based on the National Topographic Data and Map Specifications.

9 Second DEM and Flow Direction Grids
Developed by the Australian National University, the 9 second Digital Elevation Model (DEM) was used to derive the Geofabric Catchments and associated products above.
9 Second DEM Derived Stream Network v1.1.3
Rasterised fully connected and directed stream network derived from the 9 second DEM produced by ANU. Vector version is available through the Geofabric website.
