The OpenStreetMap Physical Boundaries – Coastlines dataset contains high-resolution representations of global coastlines as contributed and maintained by the OpenStreetMap community. These features are tagged using natural=coastline and define the interface between land and ocean within the OSM data model.
The coastline data is extracted from the full OSM planet file and processed into continuous, topologically correct line geometries suitable for use in basemaps, spatial analysis, and hydrological modeling. It is particularly useful for applications requiring precise rendering of shorelines or for clipping other geospatial layers to land boundaries.
HUB Ocean is a non-profit technology organization dedicated to unlocking the power of ocean data to drive sustainable ocean stewardship. Based in Norway, it develops digital tools and platforms that combine science, industry, and policy data, enabling better decisions for the health and future of the ocean.
OpenStreetMap (OSM) is an open-source, user-driven mapping platform that provides freely accessible geospatial data. Contributors use GPS, satellite imagery, and local knowledge to create and edit vector-based maps. Widely used in GIS applications, OSM supports routing, spatial analysis, and custom map rendering. It is maintained by the OpenStreetMap Foundation, which advocates for open geographic data and collaborative mapping.
