Swiss Waterways from OpenStreetMap for Flood Risk Modeling

Water features across Switzerland exported from OpenStreetMap. The data includes rivers, streams, canals, lakes, ponds, and other water bodies tagged with `waterway`, `water`, or `natural=water`. It is provided by the Humanitarian OpenStreetMap Team (HOT) and was last updated on 2026-05-14.

Use Cases

• Model flood risk based on the mapped network of rivers and streams.
• Conduct watershed analysis using the delineated water bodies and channels.
• Create environmental basemaps for contextual analysis using the comprehensive water feature data.

Strengths

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

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.
