Senegal Waterways from OpenStreetMap for Flood Risk and Watershed Analysis

Water features across Senegal, including rivers, streams, canals, lakes, and ponds, exported from OpenStreetMap. The data is built by volunteers, with completeness varying between urban and remote areas. It was last updated on 2026-05-14 and is provided by the Humanitarian OpenStreetMap Team.

Use Cases

• Model flood-risk based on mapped waterway networks.
• Conduct watershed analysis using the delineated rivers and streams.
• Create an environmental basemap context for regional planning using water body features.

Strengths

• Includes multiple water feature types (rivers, streams, canals, lakes, ponds) tagged with specific OSM keys.
• Available in multiple geospatial file formats (GEOPACKAGE, KML, SHP, GEOJSON, JSON).
• Data is licensed under the open ODbL-1.0 license.

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.
