OSM Liberty

A free Mapbox GL basemap from OpenStreetMap 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://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 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 as vector data source
Natural Earth Tiles for relief shading
Maki 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.

Use the Maputnik CLI 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 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

Take the iconset.json and upload it to the Maki Editor.
Apply your changes and download the fonts and icon set again.
Ensure you format the JSON first with cat iconset.json | jq -MS '.'
Install spritezero npm install spritezero-cli
Generate the low resolution sprites spritezero sprites/osm-liberty ./svgs/
Generate the high resolution sprites spritezero sprites/osm-liberty@2x ./svgs/
