Mali Waterways from OpenStreetMap for Hydrological Analysis

Mali's water features exported from OpenStreetMap. The data includes rivers, streams, canals, lakes, ponds, and other water bodies tagged with `waterway`, `water`, or `natural=water`. It was last updated on 2026-05-14 and is provided by the Humanitarian OpenStreetMap Team (HOT).

Use Cases

• Flood-risk modelling based on the distribution of rivers and water bodies.
• Watershed analysis using the network of rivers and streams.
• Creating an environmental basemap context from lakes, ponds, and canals.

Strengths

• Includes multiple water feature types (rivers, streams, canals, lakes, ponds).
• Derived from OpenStreetMap, a free, collaborative global map.
• Available in multiple geospatial file formats (GEOPACKAGE, KML, SHP, GEOJSON).

Limitations

• Completeness varies by region; 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.
