Australian Soil Silt Content Maps at 90-Meter Resolution

Australia-wide modelled estimates of soil silt content, released by the Terrestrial Ecosystem Research Network. The product contains 18 gridded raster maps representing the attribute and its confidence limits across six standard soil depths, with a spatial resolution of approximately 90 meters. Data collection likely spans the period from approximately 1950 to 2021.

Use Cases

• Modeling soil erosion risk based on silt content estimates across six depth layers.
• Assessing agricultural land suitability for specific crops based on soil texture data.
• Integrating soil property data into broader environmental or hydrological models for Australia.
• Validating or calibrating remote sensing algorithms for soil composition using the provided confidence limits.

Strengths

• Provides data for six standardized soil depths (0-5cm to 100-200cm), consistent with GlobalSoilMap specifications.
• High spatial resolution of 3 arc seconds, corresponding to approximately 90 x 90 meter pixels.
• Includes upper and lower confidence limits for each attribute map, offering uncertainty estimates.
• Temporal coverage spans a long period, approximately from 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.
