Boston Subway/Rail Google Map

Data

• GPS waypoints & tracks in KML format — KML is supported directly by Google (My) Maps and Google Earth. (Converted from GPX via GPSBabel.)
• GPS waypoints & tracks in GPX format — GPX (GPS Exchange Format) is supported directly in many GPS programs, and can be converted to many other formats using e.g. GPSBabel.
• Developer formats: YAML and JavaScript — For developers. With a YAML parser such as PyYAML, you can do almost anything very quickly with this data. The JavaScript format is useful for Ajax development. Let me know if you do something interesting!

About

This page is written by Erik Demaine. You are free to use it for any purpose (see below for conditions on the maps themselves). Out of historical interest, you can view a changelog of features and data.

If you notice a mistake, e.g., the location of a station is even a bit off, please let me know. I'd like to make the station coordinates as accurate as possible. All subway and commuter-rail stations should be listed; let me know if I missed one. To a lesser extent, it would be nice for the polylines to be accurate; if you know some coordinates between two stations, let me know.

In the more distant future, it would be nice to add bus routes and/or water stations as a toggle option. (Off by default, because it would be rather cluttered.) If you'd like to speed this process, please send coordinates!

The station data is accumulated manually from MBTA, manually geolocated using Map Builder and/or geocoder.us and/or iTouchMap, compiled into a YAML file, and then converted by a Python script into JavaScript data, as well as converted by another script into a GPX file. I drew the T icons using Adobe Illustrator.

Thanks to Sanghamitra Sen and James C. Reilly for correcting errors and spotting omissions. Thanks also to Brain Leonard for suggesting and helping with GPX; see his take on GPX. Thanks to Jonathan Eunice for spotting broken links and encouraging the commuter rail addition.
