Description

A bare-bones ontology for the Australian Hydrological Geospatial Fabric.

This small ontology characterises major parts of the Australian Hydrological Geospatial Fabric for their delivery as Linked Data via the Geofabric LDAPI.

This ontology accords with the Loc-I Project's requirements for the delivery of spatial Semantic Web objects.

Source Section 5.5 Page 44 in the Australian Hydrological Geospatial Fabric (Geofabric) v3.0 Product Guide
Description

Geofabric Hydrology Reporting Regions are derived from aggregations of contracted catchments from Geofabric Hydrology Reporting Catchments. This product contains two candidate reporting regions, namely AWRA Drainage Division for national scale reporting purposes and River Region for regional scale reporting purposes. More reporting regions may be added in future releases based on user requirements.

The AWRA Drainage Division is defined for the purpose of providing a stable set of reporting regions specifically for the purpose of the Bureau’s Australian Water Resources Assessment and are referred to as the 2010 and 2012 Assessment Reporting Regions.

The River Regions were based on a specification developed by Bureau hydrologists involved in water resources assessment in consultation with the Geofabric team and scientists from CSIRO and ANU. These boundaries were developed for use in regional scale reporting and hydrological modelling. The River Region boundaries were not used in the Australian Water Resources Assessment 2010 and 2012 but may be considered in the future as the resolution of reporting increases.

Though the Geofabric Hydrology Reporting Regions have been developed for the purposes of the Australian Water Resources Assessment, it is envisaged that these units can be used more generally as a standard for hydrological reporting at the national and regional scale, and thus replace the Australia River Basins 1997 (http://www.ga.gov.au/metadatagateway/metadata/record/gcat_42343). Table 31 shows the Geofabric Hydrology Reporting Regions feature class terminology and feature subtypes.
