Somalia Waterways from OpenStreetMap for Environmental Analysis

Water features across Somalia, including rivers, streams, canals, lakes, ponds, and water bodies. The data is an export from OpenStreetMap, a free collaborative world map built by volunteers, and was last updated on 2026-05-14. It is provided by the Humanitarian OpenStreetMap Team (HOT) as part of their exports grid on HDX.

Use Cases

• Model flood-risk based on the mapped network of rivers, streams, and canals.
• Conduct watershed analysis using the spatial distribution of water bodies.
• Create environmental basemaps for contextual analysis using lakes and ponds.

Strengths

• Data is available in multiple geospatial formats including GEOPACKAGE, KML, SHP, and GEOJSON.
• Explicitly includes features tagged with the OSM keys `waterway`, `water`, or `natural=water`.
• Last updated on 2026-05-14, indicating recent maintenance.

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.
