Mapterhorn - Terrain for Web Mapping

The Protomaps project is the PMTiles format, its tooling, and a 120GB basemap vector cartographic tileset created from OpenStreetMap and other open data sources. PMTiles is not limited to storing vector data - it’s also used for raster data, like scans of historical paper maps. Mapping apps often don’t just need to show vectors of buildings, boundaries and places.
