GDE HEVAE NSW: Groundwater-Dependent Ecosystems in New South Wales

GDE HEVAE NSW is a geospatial dataset from the NSW Department of Climate Change, Energy, Environment and Water. It provides mapping of groundwater-dependent ecosystems, accessible via an ArcGIS REST API. The dataset was initially published on 28/08/2024 and uses the WGS84 spatial reference system.

Use Cases

• Map groundwater-dependent ecosystem locations based on the dataset's geospatial features.
• Analyze the relationship between water resources and environmental features based on the dataset's thematic focus.
• Integrate ecosystem data into hydrological models based on the dataset's spatial reference system.
• Monitor potential changes in groundwater-dependent areas based on the dataset's update frequency.

Strengths

• Data is accessible via a live ArcGIS REST API, suggesting programmatic access.
• Spatial reference system is explicitly defined as WGS84/GDA94.
• Data custodian is the authoritative NSW Department of Climate Change, Energy, Environment and Water.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and sample data are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
