Eritrea Water Features from OpenStreetMap for Hydrological Analysis

OpenStreetMap exports provide waterway features like rivers, streams, canals, lakes, and ponds across Eritrea. Data completeness likely varies, with urban areas being more thoroughly mapped than remote regions. The Humanitarian OpenStreetMap Team (HOT) compiled this dataset, which was last updated on 2026-05-15.

Use Cases

• Model flood-risk based on mapped rivers, streams, and water bodies.
• Conduct watershed analysis using the network of waterways.
• Create environmental basemaps for regional planning using water features.

Strengths

• Includes multiple water feature types: rivers, streams, canals, lakes, ponds, and water bodies.
• Available in multiple geospatial file formats: GEOPACKAGE, KML, SHP, GEOJSON, JSON.
• Derived from OpenStreetMap, a free, collaborative global mapping project.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• OpenStreetMap completeness varies by region; remote areas may be incomplete.
