OpenMapTiles

OpenMapTiles is an extensible open tile schema based on OpenStreetMap, used to generate vector tiles for online zoomable maps and topographic basemaps. It outputs a self-contained tileset that GL map styles can render.

The schema is a collection of documented, self-contained layers you can modify, adapt, or extend, covering aeroway, boundary, building, housenumber, landcover, landuse, mountain_peak, park, place, poi, transportation, water, and waterway. Tile generation runs through a Docker-based build that imports OSM extracts into PostgreSQL and produces MBTiles output.

The code is BSD-licensed, with cartographic decisions in the schema and SQL under CC-BY. Products using maps derived from the schema must visibly credit OpenMapTiles.org or reference OpenMapTiles with a link back to the project.
