Protomaps is an open source system for interactive web maps.

There are three major parts of Protomaps:

  • PMTiles, an open archive format for pyramids of tile data, accessible via HTTP Range Requests.
  • An ecosystem of tools and libraries for creating, serving and manipulating
  • A cartographic “basemap” showing features in the world like roads, water bodies and labels, based on the OpenStreetMap dataset, and delivered as one big PMTiles archive.
