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

Geofabric conceptual architecture showing data work flows (Original source: WIRADA). Note: Data product specifications based on ISO19131:2007. 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. 1 DOT7313/12 Australian Hydrological Geospatial Fabric (Geofabric) Product suite The Geofabric consists of six integrated data products developed specifically for hydrological visualisation, analysis and reporting.

The enduring nature of the Geofabric is based on a set of contracted nodes (points) which represent These activities are guided by industry best important hydrological features in the landscape. practice, then tested and made operational through research and development. 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. 2 Australian Hydrological Geospatial Fabric (Geofabric) Geofabric Version 2 Hydrology Reporting Regions This 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. Hydrology Reporting Catchments This 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. Surface Catchments This 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 Network This 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. Surface Cartography This 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. Groundwater Cartography This 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. Figure 3.

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.
