<img align="right" alt="OSM Liberty" src="logo.png" />
|
|
|
|
A free Mapbox GL basemap for everyone with complete liberty to use and self host. OSM Liberty is a fork of OSM Bright based on free data sources with a mission for a clear good looking design for the everyday user.

|
|
|
|
## Usage
|
|
|
|
You can instantly use the style in your Mapbox GL maps. The vector tiles are served from the @klokantech public CDN
|
|
and the raster tiles, glyphs and sprites directly from GitHub.
|
|
Take a look at the [demo page source code](index.html) how to display a map.
|
|
To use it you don't need any access keys and you can host the tiles and assets yourself for complete liberty.

## Data Sources
|
|
|
|
- [OSM2VectorTiles](http://osm2vectortiles.org/) as vector data source
|
|
- [Natural Earth Tiles](naturalearthtiles.org) for relief shading
|
|
- [Maki](https://www.mapbox.com/maki-icons/) as icon set
|
|
|
|
## Map Design
|
|
|
|
The map design originates from OSM Bright but strives to reach a unobtrusive and clean design for everyday use.
|
|
Colored relief shading from Natural Earth make the low zoom levels look good.
|
|
|

**Modify Style**
|
|
|
|
You can directly modify the style with the help of the [mapbox-gl-style-editor](https://github.com/erikandre/mapbox-gl-style-editor).

|
## Icon Design

|
|
|
A [Maki](https://github.com/mapbox/maki) icon set using colors to distinguish between icon categories.
