[mkgmap-dev] Routing parameters

Fri May 15 18:45:52 BST 2015

I am curious to know how mkgmap handles the display of and text to speech
aspects of motorway junctions. It's hard to test for this without actually
creating a route and then driving it to see and hear what the Garmin is
doing with the data or to discover where it gets the information from.

I'm assuming that whatever one puts in the exit_to=* tag gets displayed and
spoken by the Garmin "assistant". Does mkgmap ever use the destination=*
tag, and if so under what circumstances?

I found this rule in the lines style sheet, but I do not understand it well
enough to help me answer my question

(highway=motorway_link | highway=trunk_link) & mkgmap:exit_hint=true &
mkgmap:dest_hint=true
  { name '${destination:ref|subst: =>} ${destination|subst:;=> |subst:/=>
}' |
         '${ref|subst: =>} ${destination|subst:;=> |subst:/=> }' |
         '${destination|subst:;=> |subst:/=> }' |
         'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_name}' |
highway=road
         'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_exit_to}' |
         'Exit ${mkgmap:exit_hint_exit_to}' |
         'Exit ${mkgmap:exit_hint_name}' |
         'Exit ${mkgmap:exit_hint_ref}'
       }

As always, thanks in advance to any help you can provide.

Dave
