The Australian Hydrological Geospatial Fabric (Geofabric) is a specialised Geographic Information System (GIS). It registers the spatial relationships between important hydrological features such as rivers, water bodies, aquifers and monitoring points.
The Surface Hydrology Polygons (National) dataset presents the spatial locations of surface hydrology polygon features and its attributes. The dataset represents the Australia's surface hydrology at a national scale. It includes natural and man-made geographic features such as: watercourse areas, swamps, reservoirs, canals, etc. This product presents hydrology polygon features which will topological connect with the hydrology line features and forms a complete flow path network for the entire continental of Australia.

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).
The surface hydrology dataset provides a seamless surface 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 water bodies. 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. It also provides information on naming, hierarchy and perennially.
Our topographic data is available for use in GIS applications, in the following scales which reflect their level of accuracy and best scale for use. The smaller the scale (i.e. 1:250 000 is a smaller scale than 1:100 000), the fewer features are depicted in the data and naturally they will be less spatially accurate. Geodata is vector data.

The National Catchment Database is a linked set of spatial layers and associated attribute tables describing key elements of the surface water hydrology of the Australian continent at a map scale of about 1:250,000. 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).

The National Groundwater Information System is a spatial database for GIS specialists that contains a range of groundwater information submitted by States and Territories. The System contains more than 800 000 bore locations with associated lithology logs, bore construction logs and hydrostratigraphy logs. 2D and 3D aquifer geometries are also available for some areas.
