Australian Soil Sand Content Maps at Six Depths and 90-Meter Resolution

Version 2 of the Soil and Landscape Grid of Australia's sand content product provides 18 raster maps estimating the mass fraction of sand across the continent. The maps cover six standard depths from 0-5 cm to 100-200 cm at a spatial resolution of 3 arc seconds (~90 meters). Data collection for this modelled estimate spans approximately the period from 1950 to 2021.

Use Cases

• Model soil water infiltration and drainage based on sand content percentages.
• Assess regional soil texture for agricultural suitability and crop planning.
• Analyze spatial patterns of soil erosion risk based on sand distribution.
• Integrate soil attribute data into broader ecological or hydrological models.

Strengths

• Provides data for six standardized soil depths consistent with GlobalSoilMap specifications.
• Offers high spatial resolution of approximately 90 meters per pixel.
• Includes upper and lower confidence limits for each attribute map.
• Temporal coverage spans over 70 years, from approximately 1950 to 2021.

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.
