Gnangara Jandakot Maximum Depth to Groundwater 2019

Maximum depth to groundwater raster data for the Gnangara and Jandakot areas of Western Australia's Swan Coastal Plain. The dataset discretizes water table elevation into 10x10 meter cells with contours displayed at 1-meter intervals. It was produced by the Department of Water and Environmental Regulation.

Use Cases

• Model groundwater-dependent ecosystems using depth to groundwater values across the Swan Coastal Plain.
• Analyze spatial patterns of water table elevation at 10-meter resolution to identify recharge zones.
• Integrate depth to groundwater contours with land use data for hydrological impact assessments.
• Monitor long-term groundwater level changes by comparing 2019 maximum values with other temporal snapshots.

Strengths

• High spatial resolution with data discretized into 10x10 meter cells.
• Contours are provided at a precise 1-meter interval for detailed elevation analysis.
• Authoritative source from a state government environmental regulation department.

Limitations

• Limited to a single year (2019), providing only a snapshot without temporal series.
• Spatial coverage is restricted to two specific areas (Gnangara and Jandakot) within Western Australia.
• Data is delivered in raster and service formats (WMS, PDF) which may require specialized GIS tools for analysis.
