Australian Soil pH Maps at Six Depths with 90-Meter Resolution

Australian soil pH (CaCl2) maps modelled at a 3 arc-second resolution (~90m pixels). The dataset contains 24 gridded maps representing pH estimates and confidence limits for six standard soil depths from 0-5 cm to 100-200 cm. It is Version 2 of the product from the Soil and Landscape Grid of Australia, superseding Release 1.

Use Cases

• Model agricultural crop suitability based on soil pH estimates across six depths.
• Assess environmental change impacts using spatially distributed soil chemistry data.
• Validate regional soil models with high-resolution (90m) gridded attribute maps.
• Evaluate model reliability for specific areas using the provided extrapolation risk measure.

Strengths

• Provides data for six standardized soil depths consistent with GlobalSoilMap.net specifications.
• Contains 24 gridded maps per attribute, including upper and lower confidence limits.
• Offers high spatial resolution with approximately 90 x 90 meter pixels.
• Includes a measure of model extrapolation risk to assess estimate reliability.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
