Waterways of Samoa from OpenStreetMap for Environmental Analysis

Samoa's water features exported from OpenStreetMap. The data includes rivers, streams, canals, lakes, ponds, and water bodies tagged with `waterway`, `water`, or `natural=water`. It was last updated on 2026-05-15 and is provided by the Humanitarian OpenStreetMap Team.

Use Cases

• Model flood risk based on mapped waterway networks.
• Conduct watershed analysis using the delineated water bodies.
• Create environmental basemaps for contextual mapping in Samoa.

Strengths

• Data is sourced from OpenStreetMap, a free, collaborative world map.
• Includes multiple vector file formats (GEOPACKAGE, SHP, GEOJSON, JSON) for flexibility.

Limitations

• Completeness varies by region; remote areas may be incomplete.
• Column-level documentation is absent; field semantics must be inferred after download.
