Soil Classification Map for the Ji-Parana River Basin in Brazil

A 1983 digital map of soil orders for the Ji-Parana River Basin in Rondonia, Brazil. The dataset was manually digitized from a 1:500,000 scale map produced by EMBRAPA, providing polygon-based classification of soil types. It is distributed as an ESRI ArcGIS Shapefile and is available on multiple platforms including NASA EarthData and Data.gov.

Use Cases

• Analyzing the spatial distribution of soil orders like Oxisols and Ultisols for agricultural suitability studies.
• Integrating soil type polygons with land cover data to assess soil-vegetation relationships.
• Using the geospatial boundaries as a base layer for hydrological modeling within the Ji-Parana River Basin.

Strengths

• Provides specific percentage coverage for soil orders: Oxisols (47%), Ultisols (24%), Entisols (14%), Alfisols (13%), and Eptisols (2%).
• Derived from an authoritative 1:500,000 scale map originally published by EMBRAPA, Brazil's agricultural research agency.
• Available on multiple platforms (NASA EarthData, Data.gov), indicating recognized utility and stability.

Limitations

• The original source map is from 1983, so the data does not reflect recent land use changes or soil degradation.
• Sources conflict on the 'last updated' metadata, with one listing 1983 and others listing 2026, creating uncertainty about versioning.
• No column names or row counts are provided in the metadata, limiting understanding of the shapefile's attribute table structure.
