Digital Soil Maps for New South Wales at 100m Resolution

Digital soil maps for New South Wales provide statewide coverage of key soil properties, including organic carbon, pH, and texture fractions. The maps are produced at a 100-meter spatial resolution for three soil depth intervals using Quantile Regression Forest techniques. The dataset is provided by the NSW Department of Climate Change, Energy, the Environment and Water and was last updated on 2026-05-28.

Use Cases

• Modeling soil carbon sequestration potential based on soil organic carbon and nitrogen maps
• Assessing agricultural land suitability based on pH, phosphorous, and cation exchange capacity
• Estimating soil water holding capacity based on texture fractions and bulk density data
• Evaluating soil health and nutrient status across different depth intervals
• Incorporating soil property uncertainty into environmental risk assessments based on upper and lower prediction limits

Strengths

• Statewide spatial coverage of New South Wales
• 100-meter spatial resolution
• Covers three soil depth intervals (0–30 cm, 30–60 cm, and 60–100 cm)
• Includes uncertainty estimates through upper (95th percentile) and lower (5th percentile) prediction limits

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
