Windshaft map tiler
A Node.js map tile library for PostGIS and torque.js, with CartoCSS styling.
- Can render arbitrary SQL queries
- Generates image and UTFGrid interactivity tiles
- Accepts, stores, serves, and applies map styles written in CartoCSS
- Supports re-projections
Being a dynamic map renderer, windshaft commits some map server 'sins' in its raw form. The idea is that you the developer will want to graft your own auth/metrics/caching/scaling on top of decent core components. Same old story: high cohesion, low coupling makes us happy. See Windshaft-cartodb.
Windshaft is a library used by cartodb.com, an Open Source Geospatial Database on the Cloud.
More examples built on top of Windshaft can be found in CartoDB's gallery.
- Node >=0.8
- npm >=1.2.1

- libcairo2-dev, libpango1.0-dev, libjpeg8-dev and libgif-dev for server side canvas support
Probably one of the more advanced uses of Windshaft library can be found at Windshaft-cartodb project.
Latest node-mapnik versions comes compiled for some platforms and architectures, in case you need it you can always compile, package and install it manually. The recommended option is to use mapnik-packaging. You can also use other alternatives:
- Source: https://github.com/mapnik/mapnik
- OSX: https://github.com/mapnik/mapnik/wiki/MacInstallation_Homebrew
- Linux: https://github.com/mapnik/mapnik/wiki/LinuxInstallation
Recommended options to build from source:
- node-mapnik: from 1.x branch, current tagged version is 1.4.15-cdb1, which is what windshaft uses.
- mapnik: node-mapnik uses a fixed version of mapnik, which currently is 82df66e, check build_against_sdk.sh#L100-L101@1.4.15-cdb1.
We maintain a set of scripts/recipes to package mapnik sdk and node-mapnik. It can help to understand what you really need to package mapnik + node-mapnik to be used from windshaft[-cartodb].
Windshaft has a unit and acceptance test suite.
To execute them, run
You'll need to be sure your PGUSER (or your libpq default) is set to a "superuser" PostgreSQL account, for example:
PGUSER=postgres npm test
Fonts: Invalid value for text-face-name
You need to install fonts at system level to be able to use them. If you face an issue like
Invalid value for
text-face-name, the type font is expected. DejaVu Sans Book (of type string) was given. probably you don't have the
required fonts, try to install DejaVu fonts or any other font needed.
Thanks to the Mapnik and Mapbox team for making such flexible tools
