# OSM Liberty [](https://github.com/maputnik/osm-liberty/blob/gh-pages/LICENSE.md) [](https://travis-ci.org/maputnik/osm-liberty)
A free Mapbox GL basemap from [OpenStreetMap](https://openstreetmap.org) 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. It is based on the vector tile schema of [OpenMapTiles](https://github.com/openmaptiles/openmaptiles).
**[https://maputnik.github.io/osm-liberty](https://maputnik.github.io/osm-liberty)**
## 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
- [OpenMapTiles](http://openmaptiles.org/) as vector data source
- [Natural Earth Tiles](http://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.

## Edit the Style
You can [edit the style directly online in Maputnik](http://maputnik.com/editor?style=https://rawgit.com/maputnik/osm-liberty/gh-pages/style.json).
Use the [Maputnik CLI](http://openmaptiles.org/docs/style/maputnik/) to edit and develop the style locally.
After you've started Maputnik open the editor on `localhost:8000`. This style actually triggered the need for the development of Maputnik.
```
maputnik --watch --file style.json
```
## Icon Design
A [Maki](https://github.com/mapbox/maki) icon set using colors to distinguish between icon categories.
**Color Palette**
Color Name | Hex Value
-------------|----------
Blue | `#5d60be`
Light Blue | `#4898ff`
Orange | `#d97200`
Red | `#ba3827`
Brown | `#725a50`
Green | `#76a723`
**Modify Icons**
1. Take the `iconset.json` and upload it to the [Maki Editor](https://www.mapbox.com/maki-icons/#editor).
2. Apply your changes and download the fonts and icon set again.
3. Ensure you format the JSON first with `cat iconset.json | jq -MS '.'`
4. Install [spritezero](https://github.com/mapbox/spritezero) `npm install spritezero-cli`
5. Generate the low resolution sprites `spritezero sprites/osm-liberty ./svgs/`
6. Generate the high resolution sprites `spritezero sprites/osm-liberty@2x ./svgs/`
