Terrestrial Groundwater Dependent Ecosystem Density Map for Victoria, Australia

A refined geospatial dataset mapping the relative density of terrestrial Groundwater Dependent Ecosystems (GDEs) across Victoria, Australia. This dataset addresses overestimation issues in the original 2010 mapping by Dresel et al. by weighting areas from very low to very high GDE density. The Department of Energy, Environment and Climate Action provides this data under a CC-BY-4.0 license, last updated in April 2026.

Use Cases

• Prioritizing conservation areas based on mapped GDE density.
• Modeling hydrological impacts on terrestrial ecosystems based on relative density weighting.
• Informing land-use planning and environmental policy based on statewide GDE distribution.
• Calibrating or validating other ecological models using the refined density estimates.

Strengths

• Addresses a known overestimation issue from the original 2010 source data.
• Provides a relative density weighting, offering more nuance than a binary presence/absence map.
• Covers the entire state of Victoria, offering a broad spatial scope.
• Available in multiple geospatial raster formats (TIFF, JPEG, ECW, JPEG 2000, GEOTIFF).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying source mapping is from 2010, which may not reflect recent ecological changes.
• Row count and exact spatial resolution are unknown, which may limit suitability assessment.
