An Infinite Map: The Protomaps Vector Basemap based on OpenStreetMap – Brandon Liu
Channel: OpenStreetMap US
Date: 2024-02-06

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.
