Acid Sulfate Soil Disturbance Risk Map for Geraldton

A geospatial dataset mapping the risk of disturbing Potential Acid Sulfate Soil (PASS) materials within 3 meters of the ground surface in Geraldton. Created by the Department of Water and Environmental Regulation for land development planning, this dataset is no longer actively maintained.

Use Cases

• Assess development applications by analyzing PASS disturbance risk likelihood to determine if additional site conditions are required.
• Model soil disturbance impacts from activities like drainage and excavation based on the defined 3-meter depth criterion.
• Integrate PASS risk likelihood data with other planning layers via WFS or GeoJSON for regional environmental assessments.

Strengths

• Data is provided in multiple standard geospatial formats including GeoJSON, SHP, and WFS for interoperability.
• Specifically designed for a practical use case: assessing development application conditions by planners.
• Includes a defined risk assessment methodology based on PASS material likelihood within a 3-meter soil depth.

Limitations

• Dataset is explicitly stated as no longer actively maintained by the originating department (DWER).
• Lacks tabular metadata such as column definitions, row counts, or sample data for analytical clarity.
