Natural and Infrastructure Features for Amazonian Study Sites

Sixteen archives contain shapefiles detailing cities, rivers, roads, and study boundaries for five Amazonian sites in Brazil. Data were digitized from official INCRA and IBGE source maps. The products were prepared between 2000 and 2004.

Use Cases

• Analyzing road network proximity to rivers and streams for hydrological studies.
• Mapping settlement and city locations relative to study area boundaries for land-use change analysis.
• Digitizing natural features like rivers from INCRA and IBGE maps for baseline environmental modeling.

Strengths

• Contains shapefiles for five distinct study sites, providing localized geographic detail.
• Source data originates from authoritative Brazilian agencies, INCRA and IBGE.
• Products were prepared during a defined 2000-2004 time period.

Limitations
