GDE Probability NSW: Groundwater-Dependent Ecosystem Likelihood Map

A geospatial dataset from the NSW Department of Climate Change, Energy, Environment and Water, initially published on 28/08/2024. It provides a probability map for identifying Groundwater-Dependent Ecosystems (GDEs) across New South Wales, Australia. The data is served via an ArcGIS REST API and is updated via the same mechanism.

Use Cases

• Modeling the distribution of ecosystems reliant on groundwater based on the probability layers.
• Assessing environmental water requirements for policy and planning based on GDE likelihood.
• Integrating GDE probability data with other hydrological or land-use datasets for comprehensive analysis.
• Creating visualizations and maps to communicate groundwater ecosystem risks and extents.

Strengths

• Data currency is explicitly stated as 28/08/2024, providing a clear reference date.
• Spatial reference systems are documented (WGS84, EPSG:3857, GDA94).
• Data access policy is listed as 'Open', facilitating reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
• Description metadata is limited; the note 'Waiting for Metadata from DPIE' suggests incomplete documentation.
