Minimum Depth to Groundwater Contours for Gnangara and Jandakot 2019

2019 minimum depth to groundwater values for the Gnangara and Jandakot areas of the Swan Coastal Plain in Western Australia. Contours are displayed using 1-meter intervals derived from raster data discretized into 10x10 meter cells.

Use Cases

• Model groundwater resource availability using the 1-meter contour intervals for hydrological studies.
• Analyze spatial patterns of minimum depth to groundwater across the 10x10 meter cell grid for the Swan Coastal Plain.
• Integrate depth to groundwater contours with land-use data to assess environmental impacts in the Gnangara and Jandakot areas.

Strengths

• Data is discretized into a consistent 10x10 meter cell grid over the study area.
• Contours are provided at a precise 1-meter interval for detailed analysis.
• Covers two specific, defined areas: Gnangara and Jandakot on the Swan Coastal Plain.

Limitations

• Contains only minimum values for a single year (2019), limiting temporal trend analysis.
• No sample data or column schema is provided, complicating initial data inspection.
• Spatial coverage is limited to two areas within Western Australia, not representative of broader regions.
