Physical and Demographic Maps of the Ji-Parana River Basin, Brazil

Maps provide physical, hydrologic, political, demographic, and societal data for the Ji-Parana River Basin in Rondonia, Brazil. The dataset includes a Digital Elevation Model, river networks, and vector sets for roads, county borders, population change from 1970-2000, and settlement projects. It was produced by NASA and used as base information for land use, biogeochemistry, soils, and water balance research.

Use Cases

• Analyzing population change from 1970 to 2000 across county borders.
• Modeling hydrologic processes using the Digital Elevation Model and river network data.
• Studying infrastructure development and settlement patterns using road and settlement project vectors.
• Integrating physical and social data for land use/land cover investigations.

Strengths

• Includes multi-decade demographic data with population change tracked from 1970 to 2000.
• Combines physical (DEM, hydrology) and social (roads, borders, settlements) data layers for integrated analysis.
• Produced by a authoritative source, NASA, for the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA-ECO).

Limitations

• Key metadata conflicts exist: the last updated date is listed as both 2001-12-31 and a future date of 2026-03 13.
• Specific row counts, file sizes, and detailed column names are not provided across any platform.
• Social data layers, such as roads, are dated (as of 2001), limiting contemporary analysis.
