[mkgmap-dev] [PATCH v4] alpha support for motorway exits and service areas

Mon Mar 9 18:43:43 GMT 2009

Mark,

Still no luck with exit announcements on my Nuvi.

I had a closer look at the pre-installed Garmin Map (NT 2008 Europe) and 
made some (interesting?) discoveries (see attached screenshots):

- On this specific motorway-junction, only the ramp for leaving
   the motorway is 'tagged' as ramp (screenshot 1, thin gray line).
   However, on other junctions, the entering ramp is 'tagged' correctly.
- The ramp for entering the motorway is named after the place where
   the junction is located (screenshot 1, Effretikon). This seems
   to only be the case if the entering ramp is 'tagged' as motorway
   (big red line)
- The ramps leaving the motorway are labeled with the corresponding
    exit-# (screenshot 2, '67')
- The exit POI is where one would expect it (screenshot 3)

Not sure what to make out of this, but maybe it would be worth 
rearranging this specific junction in OSM to match the Garmin map and 
see what effects on the produced routing instructions this will have?!?

Cheers,

- Michel
