Description
The Goulburn Broken Catchment Management Authority area in Victoria, Australia, is covered by this dataset of potential terrestrial Groundwater Dependent Ecosystems (GDEs). The Department of Energy, Environment and Climate Action created it using a GIS overlay model with satellite remote sensing, geological, and groundwater monitoring data, largely from circa 1995 to 2005. This mapping identifies landscape locations where ecosystems are likely to be at least partly dependent on groundwater, serving as a first-step screening tool.
Use Cases
Prioritize field validation sites based on identified potential GDE locations.
Screen for ecosystems potentially at risk from groundwater pumping based on the GIS overlay model.
Analyze landscape-scale patterns of potential groundwater dependence using remote sensing indicators.
Inform catchment management plans by integrating potential GDE maps with other environmental data.
Strengths
Method applied state-wide for Victoria, providing a consistent regional screening layer.
Model integrates multiple data sources: satellite remote sensing, geological data, and groundwater monitoring.
Polygon data is available in multiple geospatial formats including SHP, GDB, and WFS.
Limitations
Validation through field assessment has not been performed; locations are potential, not confirmed.
The methodology is expected to overestimate the extent of terrestrial GDEs.
Core modelling data is largely from circa 1995 to 2005, which may not reflect current conditions.
