Western Australian Soil Groups at 90-Meter Resolution

90-meter resolution raster data maps the highest probability soil group for each pixel across Western Australia. The dataset was derived from conventional soil landscape polygon maps in 2013 by the Department of Primary Industries and Regional Development. It provides the most probable soil class prediction per pixel, with two additional probable classes also available.

Use Cases

• Train a land cover classification model using the highest probability Soil Group raster as a target layer.
• Analyze soil type distribution patterns across Western Australia using the 90-meter pixel grid.
• Integrate the soil group predictions with other spatial data for agricultural land suitability modeling.
• Validate the 2013-derived soil class predictions against newer field survey data.

Strengths

• Provides a 90-meter spatial resolution for detailed soil mapping.
• Derived from authoritative conventional soil landscape mapping by a government department.
• Includes the three most probable soil classes for each location, offering prediction confidence.

Limitations

• The underlying soil mapping is from 2013 and may not reflect recent changes.
• Data is raster-based; original polygon map detail may be generalized in the conversion.
• Individual class probability rasters are not included in the standard download.
