Soil Silt Percentage Maps for Victoria at 90m Resolution

Victoria, Australia is covered by a set of digital soil maps predicting silt percentage. The dataset provides mean, 5th, and 95th percentile prediction values in raster format at a 90-meter grid resolution for six depth intervals up to 200 cm. It was produced by the Department of Energy, Environment and Climate Action using spatial interpolation methods aligned with GlobalSoilMap specifications.

Use Cases

• Modeling soil erosion and water retention based on silt content predictions.
• Informing agricultural production and land use planning based on soil property grids.
• Supporting ecosystem and pedogenesis research using the spatially exhaustive attribute estimates.
• Assessing regional to state-wide soil trends using the provided prediction and confidence interval values.

Strengths

• Provides predictions for six specific depth intervals: 0-5 cm, 5-15 cm, 15-30 cm, 30-60 cm, 60-100 cm, and 100-200 cm.
• Includes confidence intervals via 5th and 95th percentile prediction values alongside the mean.
• Follows consistent GlobalSoilMap specifications for soil information delivery.
• Offers fine-scale detail at a 90-meter grid resolution across the entire state of Victoria.

Limitations

• The description advises caution for local assessments, recommending use of confidence intervals at that scale.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
