Description
OpenStreetMap exports provide water features across Sierra Leone, including rivers, streams, canals, lakes, and ponds. The Humanitarian OpenStreetMap Team compiled this data, which was last updated in May 2026. Completeness varies by region, with urban areas likely being better mapped than remote areas.
Use Cases
Model flood risk based on the mapped network of rivers and streams.
Conduct watershed analysis using the spatial distribution of water bodies.
Create environmental basemaps for contextual analysis using the tagged water features.
Strengths
Data is available in multiple geospatial formats including GEOPACKAGE, KML, SHP, and GEOJSON.
The dataset is built from a free, collaborative global map source (OpenStreetMap).
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Completeness varies by region, with remote areas potentially being incomplete.
