Australian Hydrological Geospatial Fabric (Geofabric)The Australian Hydrological Geospatial Fabric (Geofabric) provides a framework for discovering, querying, reporting and modelling water information.
It is a specialised Geographic Information System that registers the spatial relationships between important hydrologic features such as rivers, water bodies, aquifers and monitoring points.
By detailing the spatial dimensions of these hydrofeatures and how they are connected, we are able to see how water is stored, transported and used through the landscape.
The Geofabric systemFoundation data is delivered to the Bureau and stored and managed in a maintenance geodatabase environment.
Geofabric products are then moved into a production environment and served as multiple views depending on user requirements for water accounting, assessment, forecasting and prediction.
The blueprint for building the Geofabric system is a platform independent conceptual model. This information model identifies important hydrological features and the relationships between them.
Updates to the Geofabric system are added to the conceptual model, then tested before building the database schemas and Geofabric products.
Foundation data coming into the Geofabric, and data products from the Geofabric are accompanied by a data product specification. This documentation allows users to interpret the data and identify its fitness for purpose.

The Geofabric system produces a suite of data products at different spatial and temporal resolutions, using different representations of features, from a single maintenance environment. This supports the many disparate user needs. Key to this design are formal data product specifications that describe each product as well as input datasets. Underpinning the Geofabric is a formal, modular conceptual model which allows for direct mapping between the input datasets and products.

Product suite
The Geofabric consists of six integrated data products developed specifically for hydrological visualisation, analysis and reporting.
Delivery phases
The Geofabric was launched in October 2010, with a second version released in November 2011.
Subsequent versions with improved data resolution and functionality, of approximately 1:100,000 scale based on regional scale hydrology and 1 second Digital Elevation Model (DEM), will follow.
Geofabric identity
The enduring nature of the Geofabric is based on a set of contracted nodes (points) which represent important hydrological features in the landscape.
These points have a permanent identifier included in all versions of the Geofabric, and provide a persistent framework through space and time.
A subset of the contracted nodes is used to create a simplified node-link network with associated contracted catchments.
These contracted catchments can then be aggregated in various ways to build stable reporting regions as exemplified by the Topographic Drainage Divisions and River Regions as shown in Figure 4.
Research partnerships
The Geofabric project is led by the Bureau of Meteorology in partnership with Geoscience Australia, the Australian National University Fenner School of Environment and Society, and CSIRO Water for a Healthy Country Flagship.
The partnership provides a collaborative mechanism for obtaining foundation hydrological data, maintaining and upgrading these data and improving the product suite over time.
These activities are guided by industry best practice, then tested and made operational through research and development.

Hydrology Reporting Regions
Groundwater CartographyThis product is based on the best available groundwater information from jurisdictional agencies integrated into a single dataset according to a specified data model. It is intended for groundwater feature identification, visualisation and mapping.
Hydrology Reporting RegionsThis product is based on aggregations of contracted catchments resulting in stable reporting regions. It contains candidate reporting regions at two levels, the Drainage Division and River Region level.
Surface CatchmentsThis product is based on the drainage enforced GEODATA 9 second DEM Version 3 and its associated flow direction grid to produce a hierarchy of nested catchments. It can be used to identify catchment contributing areas.
Surface CartographyThis product is based on the hydrology component of GEODATA TOPO 250K. Intended for feature identification, visualisation and mapping, it includes flow directed water course lines and water bodies and identification of contracted nodes.
Surface NetworkThis product is based on the drainage enforced GEODATA 9 second DEM Version 3 and its associated flow direction grid to produce a fully connected and directed stream network. It contains identification of contracted nodes and is intended for flow tracing and network analysis.
Hydrology Reporting CatchmentsThis product is based on the contracted nodes and contracted catchments. These features can be displayed as catchment polygons or as a node-link network. The product is intended as an input to hydrologic models and as the basis for building stable reporting regions.

Geofabric in useTopographic Drainage Divisions and River Regions are derived from the Geofabric. They provide a stable set of surface water reporting regions based on drainage-enforced digital elevation models and are used to depict where water flows and drains across the landscape.
