The Protomaps basemap is the first open source end-to-end tiled vector cartographic product that is trivially self-hostable. It’s simple to deploy anything from a small city tileset to the entire planet.
This talk covers:
- How the project fits among the existing open source ecosystem, including Planetiler, Tilezen, PMTiles, and MapLibre
- The data it uses, such as OSM or Daylight PBFs, preprocessed OSM geodata, and Natural Earth
- How to download tilesets based on minutely OSM
- How a little customization turns any OSM tags into a tileset, and tools for iterative design
Finally I’ll show some cartography examples using advanced logic, like generalizing “hairball” offramps and cloverleaf interchanges in the United States.
