Malaysia Waterways from OpenStreetMap for Flood Risk Modeling

Malaysia's water features exported from OpenStreetMap, including rivers, streams, canals, lakes, and ponds. The data is built by volunteers and its completeness varies, with urban areas likely being more detailed than remote regions. It was last updated on 2026-05-14 by the Humanitarian OpenStreetMap Team (HOT).

Use Cases

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

Strengths

• Covers multiple water feature types including rivers, streams, canals, lakes, and ponds.
• Available in multiple geospatial formats including GEOPACKAGE, SHP, and GEOJSON.
• Sourced from OpenStreetMap, a free, collaborative global mapping project.

Limitations

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