## OpenMapTiles
OpenMapTiles is a collection of vector tile layers you can mix and match to create your own vector tile sets
It is used by [OSM2VectorTiles](http://osm2vectortiles.org/) and we encourage you to collaborate, reuse and adapt existing layers
and add your own layers.
OpenMapTiles is an extensible vector tile schema you can use or mix and match to create your own vector tile sets.
It is used by [OSM2VectorTiles](http://osm2vectortiles.org/) and we encourage you to collaborate, reuse and adapt existing layers and add your own layers.
You define a self contained **Layer** together with SQL files and layer and data source definitions (like a imposm3 mapping file)
that you can then reference in a **Tileset** where you mix and match with other layers.
