Niger Waterways from OpenStreetMap for Flood Risk and Watershed Analysis

OpenStreetMap water features across Niger, including rivers, streams, canals, lakes, and ponds. The data is compiled by volunteer mappers, with completeness varying between urban and remote areas. Last updated on 2026-05-14, it is useful for creating environmental basemaps.

Use Cases

• Model flood-risk based on mapped waterway and water body locations.
• Conduct watershed analysis using the network of rivers and streams.
• Create environmental basemaps for planning using the water feature context.

Strengths

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

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Completeness varies by region, with remote areas likely being less complete.
• Column-level documentation is absent; field semantics must be inferred after download.
