El Salvador Waterways from OpenStreetMap for Hydrological Analysis

OpenStreetMap exports by the Humanitarian OpenStreetMap Team provide water features across El Salvador. The data includes rivers, streams, canals, lakes, ponds, and water bodies tagged with `waterway`, `water`, or `natural=water`. It was last updated on 2026-05-14 and is useful for environmental and risk modeling applications.

Use Cases

• Model flood risk based on the mapped network of rivers and streams.
• Conduct watershed analysis using the dataset's water body and waterway features.
• Create an environmental context basemap for planning or research based on the included lakes, ponds, and canals.

Strengths

• Data is available in multiple geospatial formats including GEOPACKAGE, SHP, and GEOJSON.
• Features are explicitly tagged using established OpenStreetMap keys: `waterway`, `water`, and `natural=water`.
• The dataset is licensed under the ODbL-1.0, a well-known open data license.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Completeness varies by region, with urban areas likely better mapped than remote areas.
• Column-level documentation is absent; field semantics must be inferred after download.
