It likely contains attributes such as name, waterway type, width, depth, and tunnel status.

Use Cases

• Map river networks and water bodies based on the 'waterway' and 'natural' tags.
• Analyze water feature dimensions and infrastructure based on attributes like 'width', 'depth', 'tunnel', and 'covered'.
• Perform multilingual place-name analysis using the 'name', 'name:en', and 'name:ja' attributes.

Strengths

• Data is sourced from OpenStreetMap, a global collaborative mapping project.
• Available in multiple geospatial formats: GEOJSON, SHP, GEOPACKAGE, KML.
• Includes a defined set of 13 potential attributes for water features.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or contributor bias inherent to OpenStreetMap.
