Gnangara Jandakot Minimum Water Table Elevation Raster 2019

Department of Water and Environmental Regulation data provides minimum water table elevation values for 2019 over the Gnangara and Jandakot areas. The raster data is discretised into 10x10 meter cells across the Swan Coastal Plain in Western Australia, with contours displayed at 1-meter intervals.

Use Cases

• Model groundwater flow dynamics using the 10x10 meter cell water table elevation raster.
• Analyze spatial patterns of minimum water table elevation across the Gnangara and Jandakot study areas.
• Integrate water table elevation contours with other hydrogeological datasets for regional aquifer assessment.

Strengths

• High spatial resolution with data discretised into 10x10 meter cells.
• Contours are provided at precise 1-meter intervals for elevation analysis.
• Data is sourced from the authoritative Department of Water and Environmental Regulation.

Limitations

• Data is a single snapshot for 2019, lacking temporal depth for trend analysis.
• Spatial coverage is limited to the Gnangara and Jandakot areas of the Swan Coastal Plain.
• Access requires handling multiple file formats including WMS, PDF, and ArcGIS services.
