FAQ

What water features are included?

OSM Water includes natural lakes, river polygons, reservoirs, canals, ocean boundaries, and other water body features extracted from OpenStreetMap.

How is this different from OSM coastlines?

OSM Water includes all inland and coastal water body polygons, while OSM coastlines specifically provide land-ocean boundary lines. This dataset includes coastlines as part of the ocean polygon.
