[mkgmap-dev] Translating route=bus relations

Clinton,

Thank you for confirming my thinking.  I would like to see this functionality
committed to mkgmap.

Do you think that it could work without a TYP file?  I suppose that you are
defining custom symbols for bus/tram/rail stops and custom line styles for
the routes, by operator or network or vehicle type.

Could routing make sense?  Not all way attributes are accessible in every
unit, but a subset could be.  The Edge 705 can be told to avoid unpaved,
toll roads or highways.  For example, we could define long distance routes
as toll=yes, and subway routes as unpaved.  But this might only be practical
if the layer contained all walkable ways, which would blow up the size.
Good routing would also have to know about schedules.  This is something that
could be implemented in a GPS-enabled smartphone or netbook within GpsMid
or the like.  (There are web-based solutions already, though.)

Could you please try out if it works with mkgmap now?
