GTFS is a format that Google started for storing information about public transit systems:
http://code.google.com/transit/spec/transit_feed_specification.html If you have specific questions about the format that are not addressed by the documentation, you can try the transit developers group: http://groups.google.com/group/transit-developers/ Keep in mind that the format is far from being a "standard", and nearly every transit agency has something in their GTFS dataset which is not part of the current specification. There are also a few tools for importing GTFS data into a SQL database, this may help you take a better look at what is in the data. Here is one such tool: http://cbick.github.com/gtfs_SQL_importer/html/index.html Cheers, Robert On Wed, Apr 21, 2010 at 11:29 AM, Thomas Cort <[email protected]> wrote: > The coordinates don't appear to be very accurate.
