Liberia Waterways from OpenStreetMap for Flood Risk and Watershed Analysis

OpenStreetMap exports of water features across Liberia, including rivers, streams, canals, lakes, and ponds. The data is compiled by the Humanitarian OpenStreetMap Team (HOT) and was last updated on 2026-05-14. Completeness varies by region, with urban areas likely being more thoroughly mapped than remote areas.

Use Cases

• Model flood risk based on the mapped network of rivers and streams.
• Conduct watershed analysis using the delineated water bodies and waterways.
• Provide environmental context for basemaps using the tagged lakes, ponds, and canals.

Strengths

• Data is available in multiple geospatial formats including GEOPACKAGE, SHP, and GEOJSON.
• Covers a defined geographic region (Liberia) and includes a variety of water feature types.

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.
