Maximum Water Table Elevation Raster for Gnangara Jandakot 2019

Gnangara Jandakot Water Table Elevation (Raster) – 2019 Max contains maximum water table elevation values for 2019, discretised into 10x10m cells over the Swan Coastal Plain in Western Australia. The dataset was created by the Department of Water and Environmental Regulation and contours are displayed using 1m intervals.

Use Cases

• Model groundwater flow and aquifer recharge using the 10x10m cell water table elevation (WTE) raster data.
• Analyze spatial patterns of depth to groundwater (DTGW) across the Gnangara and Jandakot study areas.
• Generate contour maps of water table elevation with 1m intervals for hydrological assessment.
• Integrate WTE raster layers via WMS or WFS services for environmental impact studies in the Swan Coastal Plain.

Strengths

• Data is discretised into a fine 10x10 meter grid cell resolution.
• Contours are provided at a detailed 1-meter interval for elevation analysis.
• Covers the specific and environmentally significant Gnangara and Jandakot areas of the Swan Coastal Plain.

Limitations

• Dataset is a single snapshot from 2019, lacking temporal depth for trend analysis.
• Available primarily as service layers (WMS, WFS) and PDFs, which may complicate direct raster analysis for some users.
