Western Australian Soil Group Confusion Index Raster

A 90-meter pixel raster map shows the confusion index between the two most probable soil groups across Western Australia. The dataset, created by Karen Holmes of DPIRD in 2013, is derived from conventional soil landscape polygon mapping. It provides a quantitative measure of prediction uncertainty for soil classification.

Use Cases

• Analyze soil mapping uncertainty by examining the Confusion Index raster to identify regions where predicted soil groups have similar probabilities.
• Integrate the Confusion Index with the three most probable soil class layers to assess the reliability of automated soil group predictions.
• Use the 90-meter pixel resolution raster for spatial analysis of soil classification confidence across different Western Australian landscapes.

Strengths

• Provides a specific confusion index metric quantifying prediction uncertainty between the top two soil groups.
• Derived from authoritative conventional soil landscape mapping completed in 2013 by the Department of Primary Industries and Regional Development.
• Data is available in multiple formats including WMS and ArcGIS Server Map Service for integration into GIS workflows.

Limitations

• The underlying soil type predictions are from 2013 and may not reflect recent land use changes or soil degradation.
• Individual soil class probability rasters are not included in the standard release and are only available on request.
• The dataset's utility is limited to Western Australia and may not be applicable for comparative studies in other regions.
