Global Derived Soil Properties on a 0.5-Degree Grid (ISRIC-WISE)

A global raster dataset of derived soil properties generated from the World Inventory of Soil Emission Potentials (WISE) database. The data includes variables like total available water capacity, soil organic carbon density, and soil pH for two depth ranges. It was created by N.H. Batjes and is based on 106 soil units from the Soil Map of the World.

Use Cases

• Modeling global soil water availability based on total available water capacity.
• Estimating soil carbon stocks for climate models based on soil organic carbon density layers.
• Analyzing soil acidity and its spatial distribution based on soil pH raster files.
• Mapping foundational soil properties for agricultural or ecological assessments based on the derived GIS layers.

Strengths

• Derived from the established World Inventory of Soil Emission Potentials (WISE) database.
• Provides uniform data for 106 distinct soil units defined in the global Soil Map of the World.
• Includes key soil variables like carbon density and pH for two standard depth ranges (0-30cm and 0-100cm).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and file size are unknown, which may limit suitability assessment.
