A free Mapbox GL basemap style for everyone with complete liberty to use and self host. dBi OSM Liberty Topo is a fork of OSM Liberty which 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, with terrain layers from non-OpenStreetMap sources.
Preview OSM Liberty with Maputnik
You can use the style in your Mapbox GL maps.
By default, the vector tiles and glyphs are served from Maptiler Cloud and the raster tiles and sprites directly from GitHub. You would need to subscribe to Maptiler Cloud to get an access key and replace the placeholder {key} for the vector source and glyphs with your own key.
Another option is to create your own vector tiles with OpenMapTiles and host the tiles and assets yourself for complete liberty.

- OpenMapTiles as vector data source
- Natural Earth Tiles for relief shading
- Maki as icon set
- AWS Terrain Tiles as hillshade layer
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.
You can edit the style directly online in Maputnik.
This style actually triggered the need for the development of Maputnik.
A pre-commit hook is included to validate and format the JSON styles using
mapbox-gl-style-spec
.
To use, just install the NPM dev dependencies:
npm install
and then validate or format the style with
npm run validate
npm run format
Validation and reformatting will happen automatically on commit if you have the dependencies installed.
A Maki icon set using colors to distinguish between icon categories.
Maki is a living project and adds new icons over time, which means that there
could be new icons that OSM Liberty could use for POIs. maki_list.py
is a
simple script to list both the names in OSM Liberty's iconset that don't map to
any valid Maki name, and the Maki names that are not currently used in OSM
Liberty's iconset. You can run the script with python3 maki_list.py
.

Modify Icons
- Take the
iconset.json
and import it to the Maki Editor. - Apply your changes and download the icons in SVG format and the iconset in JSON format.
- Mandatory if the updated
iconset.json
should become part of this repo: Format the JSON withcat iconset.json | jq -MS '.'
for better legibility. - Add the SVG files from the folder svgs_not_in_iconset to the folder
svgs
downloaded from the Maki Editor. These are the SVGs for road shields, the dot used for city and town layers and the road area pattern which could not be modified using the Maki Editor. To modify these you could use e.g. Inkscape. - Install spritezero-cli:
npm install -g @beyondtracks/spritezero-cli
(We're using a maintained fork of https://github.com/mapbox/spritezero-cli.) - Generate the low resolution sprite:
spritezero osm-liberty ./svgs/
- Generate the high resolution sprite:
spritezero --retina osm-liberty@2x ./svgs/
