18 gridded maps model the Available Volumetric Water Capacity of Australian soils at a 90-meter resolution. The Soil and Landscape Grid of Australia produced this version 2 product, covering depths from 0-5 cm down to 100-200 cm. Its temporal coverage spans approximately 1950 to 2021, aligning with GlobalSoilMap specifications.
Use Cases
- Modeling soil water availability for crop growth based on the Available Volumetric Water Capacity attribute.
- Assessing regional water retention and drought resilience based on soil property maps at six standard depths.
- Integrating soil hydraulic property data into larger environmental or climate models based on the 3 arc-second geospatial raster format.
Strengths
- Spatial resolution of 3 arc seconds (~90 meters) provides detailed national coverage.
- Includes 18 maps per attribute, representing data and confidence limits for six standard soil depths.
- Adheres to the internationally recognized GlobalSoilMap data standard.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for some analytical tasks.
