Seychelles Waterways from OpenStreetMap for Flood Risk and Watershed Analysis

OpenStreetMap exports provide water features across the Seychelles, including rivers, streams, canals, lakes, and ponds. The data is contributed by volunteers and managed by the Humanitarian OpenStreetMap Team, with completeness varying between urban and remote areas. Last updated on 2026-05-15, it supports environmental and hydrological applications.

Use Cases

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

Strengths

• Includes multiple water feature types (rivers, streams, canals, lakes, ponds) tagged with specific OSM keys.
• Available in multiple geospatial file formats (GEOPACKAGE, KML, SHP, GEOJSON, JSON).
• Managed by the Humanitarian OpenStreetMap Team (HOT), a known organization in the open mapping space.

Limitations

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