Brazil Soil Classification Maps with Detailed Component Tables

Soil maps of Brazil provide three classification levels: a 249-class detailed system, a 70-class generalized system, and a 19-class generalized system. The data is a digitized version of the MAPA DE SOLOS DO BRASIL originally published by EMBRAPA in 1981 and digitized by the U.S. Geological Survey's EROS Data Center in 1992. Each soil class is further described by component soil types and associated pH classifications in accompanying tables.

Use Cases

• Classify land areas using the 249-class detailed soil taxonomy for high-resolution agricultural zoning.
• Analyze soil component tables to correlate specific soil types with their documented pH classifications.
• Compare regional soil distributions using the 70-class or 19-class generalized maps for broader ecological studies.
• Integrate soil class polygons with other geospatial layers for land capability and erosion risk assessment.

Strengths

• Three distinct classification maps provide flexibility for analysis at different resolutions (249, 70, and 19 classes).
• Includes component tables detailing soil types and pH classifications for each mapped class.
• Digitized from an authoritative source (EMBRAPA, 1981) by a recognized institution (U.S. Geological Survey).

Limitations

• The underlying soil survey data is from 1981 and may not reflect current land use or soil conditions.
• Specific row counts, file sizes, and column details for the digital data are not provided.
• The original digitization was completed in 1992, and the data format may require conversion for modern GIS tools.
