Australian Soil Depth Maps at 90-Meter Resolution

Australia-wide modelled estimates of soil depth across six standard soil layers, produced by the Soil and Landscape Grid of Australia. The dataset contains 18 gridded raster maps at a 3 arc-second resolution (~90 meters) and covers an approximate period from 1950 to 2021. It is released under a Creative Commons Attribution 4.0 license and adheres to GlobalSoilMap specifications.

Use Cases

• Modeling soil water retention and carbon storage based on soil depth profiles.
• Assessing agricultural land suitability and crop yield potential across Australia.
• Informing environmental impact assessments and land management strategies.
• Calibrating and validating continental-scale hydrological and ecological models.

Strengths

• High spatial resolution of approximately 90 meters per pixel.
• Includes 18 maps providing depth estimates and confidence limits for six standard soil layers.
• Adheres to the international GlobalSoilMap data standard.
• Covers a long temporal 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.
