Hungarian Waterways from OpenStreetMap for Flood Risk and Watershed Analysis

OpenStreetMap exports provide water features across Hungary, including rivers, streams, canals, lakes, and ponds. The data is compiled by the Humanitarian OpenStreetMap Team (HOT) and was last updated on 2026-05-14. Completeness varies by region, with urban areas likely being better mapped than remote ones.

Use Cases

• Model flood-risk based on the mapped network of rivers, streams, and canals.
• Conduct watershed analysis using the spatial distribution of water bodies.
• Create environmental basemap context for planning using lakes, ponds, and other natural water features.

Strengths

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

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• 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.
