South Korean Water Features from OpenStreetMap for Flood Modeling

Water features across South Korea exported from OpenStreetMap. The data includes rivers, streams, canals, lakes, ponds, and other water bodies tagged with `waterway`, `water`, or `natural=water`. It was last updated on 2026-05-14 and is provided by the Humanitarian OpenStreetMap Team under the ODbL-1.0 license.

Use Cases

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

Strengths

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

Limitations

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