OpenStreetMap US

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.
