Mongolia Waterways from OpenStreetMap for Flood Modeling

Mongolia's water features, including rivers, streams, canals, lakes, and ponds, exported from OpenStreetMap. The data is contributed by volunteers and maintained by the Humanitarian OpenStreetMap Team. It was last updated on 2026-05-14.

Use Cases

• Flood-risk modeling based on waterway and water body locations.
• Watershed analysis based on river and stream network data.
• Creating environmental context basemaps based on lakes, ponds, and canals.

Strengths

• Includes multiple water feature types (rivers, streams, canals, lakes, ponds).
• Data is available in multiple geospatial file formats (GEOPACKAGE, SHP, GEOJSON, JSON).
• Last updated on 2026-05-14, suggesting recent maintenance.

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.
