Western Australian Soil Groups Second Highest Probability Raster

Department of Primary Industries and Regional Development provides soils mapped in raster format with 90-meter pixels. The dataset contains the second highest probability soil class predicted per pixel, derived from conventional soil landscape mapping in 2013.

Use Cases

• Classify land suitability by analyzing the second highest probability soil group raster.
• Validate soil mapping accuracy by comparing the top two predicted soil groups per 90-meter pixel.
• Model soil distribution patterns using the predicted probability rasters for Western Australian Soil Groups.

Strengths

• Raster data provides spatially continuous coverage at a 90-meter pixel resolution.
• Derived from authoritative conventional soil landscape mapping (polygon maps).
• Includes predicted probability for soil class occurrence, enabling uncertainty assessment.

Limitations

• Dataset contains only the second highest probability class; full probability layers require separate request.
• Based on 2013 source mapping, which may not reflect recent land use changes.
• Raster format may generalize soil boundaries compared to original polygon data.
