[mkgmap-dev] Incorrect runabout exit indication

From SPA spa at thecyberinn.com on Tue Sep 30 15:08:13 BST 2014

Greetings Andy

All roundabouts... mmm did I say so?

Ok here is an example of a roundabout:
Round about position:
55.586085, 11.857095

Roundabout  approach direction:
MY 6 o'clock

To complete my journey I need to exit the roundabout at:
MY 12 o'clock

The voice in Danish guides me correctly by telling me to take the second

The icon on the navigations window of my GPS (top left)
indicates that I have to exit the roundabout at:
MY 9 o'clock

Screenshot of my GARMIN:


P.S. Remember... life is not about the destination, but the amazing journey.

Well "all" is quite a lot.  He must have driven around lots of roundabouts
to test that :-)

Seriously, an example would still help - specifically to see if the
roundabouts concerned have a node shared between one road's exit flare and
another's entrance.  It would also allow other who use mkgmap themselves to
chip in and say "_my_ map does/does not have the problem at that
roundabout", to get a few more data values than 2, to try and figure out
what might be the difference that is causing the problem.

I've just tried simulating a route through a bunch of nearby roundabouts (on
an eTrex Vista HCx and a Nuvi 265W) and I'm not seeing the problem as
described - in each case the on-screen pictures (including the small one on
the Nuvi) matches the verbal direction.

I'm using "mkgmap-r1919" (quite old) and the options "--add-pois-to-areas
--remove-short-arcs --levels="0=24, 1=22, 2=21, 3=19, 4=18, 5=16" --route
