Cambodian Waterways from OpenStreetMap for Flood Risk Modeling

Water features across Cambodia exported from OpenStreetMap. It includes rivers, streams, canals, lakes, ponds, and other water bodies tagged with `waterway`, `water`, or `natural=water`. The Humanitarian OpenStreetMap Team (HOT) maintains this export, last updated on 2026-05-14.

Use Cases

• Flood-risk modeling based on the mapped network of rivers, streams, and canals.
• Watershed analysis based on the spatial distribution of lakes, ponds, and water bodies.
• Creating environmental basemap context for Cambodia based on comprehensive waterway features.

Strengths

• Data is sourced from OpenStreetMap, a free, collaborative world map built by volunteers.
• Covers multiple water feature types including rivers, streams, canals, lakes, and ponds.
• Available in multiple geospatial file formats including GEOPACKAGE, SHP, and GEOJSON.

Limitations

• Completeness varies by region; urban areas are usually well-mapped, 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.
