Waterways of Nigeria from OpenStreetMap for Environmental Analysis

Water features across Nigeria, including rivers, streams, canals, lakes, and ponds, tagged with `waterway`, `water`, or `natural=water`. The data is sourced from OpenStreetMap, a free collaborative world map, and is provided by the Humanitarian OpenStreetMap Team (HOT). It was last updated on 2026-06-25.

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 planning and research using the waterway features.

Strengths

• Data is available in multiple geospatial formats including GEOPACKAGE, SHP, and GEOJSON.
• The dataset is derived from OpenStreetMap, a widely used collaborative mapping project.

Limitations

• Coverage reflects volunteer mapper activity; urban areas are usually well represented while remote areas may be sparse.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
