The plugin allows the import of nodes, links and catchments from the Bureau of Meteorology’s Hydrological Geospatial Fabric (Geofabric). This means that users of Source in ‘geographic’ (or Source Catchments) mode are now able to define the flow network using three options, not two:
Automatic delineation using a Digital Elevation Model;
Input of a map of catchments, followed by manual definition of nodes and links; and
Import of catchments, nodes and links from the Geofabric.
As a user of this plugin, please note the following:
It is highly recommended that you familiarise yourself with both Source and the Geofabric before attempting to use this plugin. If you have not yet downloaded the Geofabric, you can do so here: www.bom.gov.au/water/geofabric/
The Australian Hydrological Geospatial Fabric (Geofabric) is a specialised Geographic Information System (GIS). It identifies the spatial relationships of important hydrological features such as rivers, lakes, reservoirs, dams, canals and catchments.
The Geofabric is provided as a number of different products. The part of the Geofabric used by this plugin is the SH Network and the SH catchments. In v2.0 of the Geofabric these products are based on the national 9 second Digital Elevation Model (DEM). It is anticipated that later versions will be based on a more detailed 1 second DEM.
The Geofabric products are provided by the BoM free of charge under the creative commons license conditions mentioned above.
