Brazil Waterways from OpenStreetMap for Flood Modeling

OpenStreetMap data on water features across Brazil, exported by the Humanitarian OpenStreetMap Team. It includes rivers, streams, canals, lakes, ponds, and other water bodies tagged with `waterway`, `water`, or `natural=water`. The dataset was last updated on 2026-05-15.

Use Cases

• Flood-risk modeling based on the spatial distribution of rivers, streams, and lakes.
• Watershed analysis based on the network of waterways and water bodies.
• Creating environmental basemaps for contextual analysis based on the comprehensive water feature data.

Strengths

• Data is sourced from OpenStreetMap, a free, collaborative global mapping project.
• Covers multiple water feature types including rivers, streams, canals, lakes, and ponds.
• Available in multiple geospatial file formats including GEOPACKAGE, KML, SHP, and GEOJSON.

Limitations

• Completeness varies by region; urban areas are usually well-mapped while remote areas may be incomplete.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
