Mauritius Waterways from OpenStreetMap for Flood Risk Analysis

OpenStreetMap exports provide water features across Mauritius, including rivers, streams, canals, lakes, and ponds. The Humanitarian OpenStreetMap Team (HOT) maintains this data, last updated on 2026-05-14. Completeness varies by region, with urban areas typically well-mapped and remote areas potentially incomplete.

Use Cases

• Flood-risk modelling based on the spatial distribution of waterways and water bodies.
• Watershed analysis using the network of rivers, streams, and canals.
• Creating environmental basemaps for contextual analysis using the water feature geometry.

Strengths

• Data is available in multiple geospatial formats including GEOPACKAGE, KML, SHP, and GEOJSON.
• Includes features tagged with specific OSM keys: `waterway`, `water`, and `natural=water`.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Completeness varies by region, with remote areas potentially incomplete.
• Row count is unknown, which may limit suitability assessment.
