Georgia Waterways from OpenStreetMap for Flood Risk Analysis

A 2026-05-15 export from OpenStreetMap contains water features across Georgia, including rivers, streams, canals, lakes, and ponds. The data is compiled by the Humanitarian OpenStreetMap Team (HOT) and is available in multiple geospatial formats. It is licensed under the Open Database License (ODbL-1.0).

Use Cases

• Model flood-risk based on the mapped network of rivers and streams.
• Conduct watershed analysis using the spatial distribution of water bodies.
• Create environmental basemaps for regional planning using the waterway features.

Strengths

• Data is available in six interoperable geospatial formats, including GEOPACKAGE, KML, and GEOJSON.
• Last updated on 2026-05-15, indicating recent data maintenance.
• Explicitly sourced from OpenStreetMap tags `waterway`, `water`, and `natural=water`.

Limitations

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