Waterways of Réunion from OpenStreetMap for Environmental Analysis

OpenStreetMap volunteers provide water features across Réunion, including rivers, streams, canals, lakes, and ponds. Completeness varies by region, with urban areas usually well-mapped and remote areas potentially incomplete. The Humanitarian OpenStreetMap Team (HOT) last updated this export on 2026-05-14.

Use Cases

• Model flood-risk based on mapped rivers, streams, and canals.
• Conduct watershed analysis using the network of water features.
• Create an environmental basemap context incorporating lakes, ponds, and water bodies.

Strengths

• Includes multiple water feature types tagged with `waterway`, `water`, or `natural=water`.
• Available in multiple geospatial file formats including GEOPACKAGE, KML, SHP, and GEOJSON.
• Last updated on 2026-05-14, suggesting recent maintenance.

Limitations

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