Water Features Across Portugal from OpenStreetMap

Portugal's water features exported from OpenStreetMap. The dataset includes rivers, streams, canals, lakes, ponds, and water bodies tagged with `waterway`, `water`, or `natural=water`. It was last updated on 2026-05-14 by the Humanitarian OpenStreetMap Team (HOT).

Use Cases

• Flood-risk modelling based on the spatial distribution of waterways and water bodies.
• Watershed analysis using the network of rivers, streams, and canals.
• Creating environmental basemap context from lakes, ponds, and other natural water features.

Strengths

• Data is available in multiple geospatial formats including GEOPACKAGE, KML, SHP, and GEOJSON.
• Covers a defined geographic region (Portugal).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Completeness varies by region; urban areas are usually well-mapped, remote areas may be incomplete.
