Geofabric stream network and catchment boundaries
Our knowledge of Australia's water landscape will further improve with the forthcoming launch of Geofabric Version 2.0.
The Geofabric – or as it is formally known, the Australian Hydrological Geospatial Fabric – is a specialised Geographic Information System that identifies spatial location, connections and relationships between hydrological features such as rivers, lakes, water storages and catchments.
Version 2.0, which is scheduled for release at the spatial@gov conference in Canberra in November 2011, includes a number of new features and an update of all components that were available in Geofabric Version 1.0.
New features include a groundwater cartography product, a hydrology reporting catchments product and a hydrology reporting regions product.
The 'Geofabric groundwater cartography' product is a national compilation of groundwater boundaries bringing together existing groundwater mapping sourced from the best available datasets across Australia.
The 'Geofabric hydrology reporting catchments' product identifies contracted nodes and contracted catchments that can be viewed as either a node-link network or as catchment polygons.
The 'Geofabric hydrology reporting regions' product aggregates contracted catchments to create reporting regions. This release includes two examples designed for the purposes of the Australian Water Resources Assessment.
Version 1.0 products have been updated with improved stream connectivity and new hydrological features, such as water storage inflow and outflow nodes.
When released, Geofabric products will be accompanied by a product guide, metadata, product schemas, data dictionaries, data product specifications and tutorials.
