OSM Bright is a sensible starting point for quickly making beautiful maps based on an OpenStreetMap database. It is written in the Carto styling language and can be opened as a project in TileMill.
The style is still a work in progress and you are encouraged to use the issue tracker to note missing features or problems with the current implementation.
If you don't already, you need to have PostgreSQL installed & running with a PostGIS database setup within it. See the PostGIS documentation for full information on how to do this
You will need an OSM database extract in one of the following formats:
- .osm.pbf (binary; smallest & fastest)
- .osm.bz2 (compressed xml)
- .osm (xml)
You can find appropriate data extracts for a variety of regions at http://download.geofabrik.de or http://downloads.cloudmade.com. Exracts of select metropolitan areas are available at http://metro.teczno.com. See the OSM wiki for information about (very large) full-planet downloads.
You need to process this data and import it to your PostGIS database. You can do this with either Imposm or osm2pgsql; see their respective websites for installation instructions.
If you are using Imposm, you should use the included mapping configuration which includes a few important tags compared to the default. The Imposm import command looks like this:
imposm -U <postgres_user> -d <postgis_database> \
-m /path/to/osm-bright/imposm-mapping.py --read --write \
--optimize --deploy-production-tables <data.osm.pbf>
See imposm --help
or the online documentation for more details.
If you are using osm2pgsql the default style file should work well. The osm2pgsql import command looks like this:
osm2pgsql -c -G -U <postgres_user> -d <postgis_database> <data.osm.pbf>
See man osm2pgsql
or the online documentation for more details.
You'll need to adjust some settings for things like your PostgreSQL connection information.
- Make a copy of
configure.py.sample
and name itconfigure.py
. - Open
configure.py
in a text editor. - Make sure the "importer" option matches the program you used to import your data (either "imposm" or "osm2pgsql").
- Optionally change the name of your project from the default, 'OSM Bright'.
- Adjust the path to point to your MapBox project folder.
- Make any adjustments to the PostgreSQL connection settings. Your database may be set up so that you require a password or different user name.
- Optionally adjust the query extents or shapefile locations. (Refer to the comments in the configuration file for more information.)
- Save & close the file.
This will create a new folder called "build" with your new project, customized
with the variables you set in configure.py
and install a copy of this build
to your MapBox project folder. If you open up TileMill you should see your new
map in the project listing.
You're now ready to start editing the template in TileMill!
