Acid Sulfate Soil Risk Map for Pilbara Coastline Development Planning

A spatial dataset assessing the risk of disturbing Potential Acid Sulfate Soil (PASS) materials within 3 meters of the ground surface along the Pilbara coastline. It was created by the Department of Water and Environmental Regulation for planners to evaluate development application conditions. The dataset is no longer actively maintained by DWER.

Use Cases

• Identify high-risk development sites for PASS material disturbance using the 3-meter depth risk assessment.
• Analyze spatial patterns of acid sulfate soil risk along the Pilbara coastline for regional planning.
• Support regulatory decisions on land development applications by referencing the mapped risk likelihood.

Strengths

• Provides a specific 3-meter depth criterion for risk assessment, relevant to common excavation and drainage activities.
• Covers the geographically distinct Pilbara coastline region.
• Offers data in multiple geospatial formats including GeoJSON, SHP, and Geopackage for tool flexibility.

Limitations

• Dataset is explicitly stated as no longer actively maintained, indicating potential staleness.
• Lacks tabular metadata such as row count, column names, or sample data for quantitative analysis.
• Risk model is based on a single, fixed depth parameter (3m) which may not suit all disturbance scenarios.
