Open Metro Maps Free maps for rapid transit networks

Our mission

Schematic maps for public transportation networks are essential tools for orientation and navigation in cities. Unfortunately, these maps are usually proprietary resources that pose strong limits on what you are allowed to do with them. The owners of the material often charge a fee for displaying the content on websites, apps or printed material and they don't allow you to change anything on the map itself. This alone prevents creative use of these maps. Furthermore, you only get a PDF document – this makes interactive content hard to create. We're here to change that by providing open source tools and file formats for creating free schematic metro maps. Read more.

Project status

The project is in alpha stage. Things are still changing quickly and many things are not easy to use and fully functional yet. At this point, some expertise in programming is required to get involved with the project. To get an impression of what we're getting at, have a look at the Demo page. You can also follow us on Twitter or have a look at the contributions we submitted to the OpenStreetMap with our OSM account.
