Waterways of the Dominican Republic for Flood Risk and Watershed Analysis

OpenStreetMap volunteer contributions provide a detailed map of rivers, streams, canals, lakes, and ponds across the Dominican Republic. The Humanitarian OpenStreetMap Team (HOT) exports this data in multiple geospatial formats, including GeoPackage and GeoJSON. Coverage likely varies, with urban areas being well-represented and remote areas potentially sparse.

Use Cases

• Model flood risk based on mapped waterway networks.
• Conduct watershed analysis using the spatial distribution of rivers and streams.
• Create environmental context basemaps for planning using tagged water bodies.

Strengths

• Data is available in six common geospatial formats, including GeoPackage and GeoJSON.
• Derived from OpenStreetMap, a free, collaborative global mapping project.
• Last updated timestamp is explicitly provided: 2026-06-27.

Limitations

• Coverage reflects volunteer mapper activity, leading to potential urban bias and sparse data in remote areas.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total size are unknown, which may limit suitability assessment.
