Abstract

The dataset was derived by the Bioregional Assessment Programme from Geofabric data provided by the Bureau of Meteorology. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This datasets contains AHGFContractedCatcments occuring within the Lockyer valley catchment that have been further aggregated to define major sub-catchments. AGHFContractedCatchments are based upon the fully disaggregated stream segment level catchments derived from GEODATA 9 second DEM foundation data. These data define a catchment for every stream segment in the Surface Network product. The AHGFContractedCatchments is the set of predefined aggregated catchments. This is the component of the product whose outflow node is a Contracted Node that is guaranteed to persist.

Purpose

To support the Geofabric and provide a topographic basis for classification and reporting of analyses of the subcatchments.

Dataset History

The AHGFContractedCatchments are aggregations of the GEODATA 9 second DEM catchments that participate in a relationship of common areal extent based upon the location of a Contracted Node from both the Geofabric Surface Cartography and Geofabric Surface Network products. Levels of Contracted Confidence is further described in the Geofabric User Guide.

The AHGF contracted stream segment level catchments were selected based on the major streams that occur within the Lockyer valley catchment. These stream segment level catchments were then aggregated using ArcGIS to create AHGF sub-catchments for the Lockyer.
