[mkgmap-dev] process-exits and Oregon 600

Thu Jun 4 08:09:32 BST 2015

Hi Micha,

now I am no longer sure what you are talking about. You said that your
problem was solved by removing the line 

        highway=motorway_link & mkgmap:label:1!=* { set
        mkgmap:label:1 = 'Exit' } 
from your style. I tried to find out why this line
causes trouble and found no reason as long
as the line doesn't appear before the blocks for the hints
which start at line 36 in the default style file lines of r3605:
(highway=motorway_link | highway=trunk_link) & mkgmap:exit_hint=true & mkgmap:dest_hint=true
....

I don't use the device for testing, I create a route in MapSource and check
the list of "directions".

    Hi Gerd,

      the exits were always
          named correctly, I checked that by looking directly into the img-files. The
      GPS just wouldn't display the hint.

      Hi Micha,

        I cannot yet reproduce your result. I tried this:

        Add the line

        highway=motorway_link & mkgmap:label:1!=* { set
        mkgmap:label:1 = 'Exit' } 

        in the default style file at line 65, before the line

        highway=* {name '${name}' | '${ref}' }

        Execute mkgmap with options --route --process-exits
        --process-destinationand this modified style. 

        I see the right hint for node 988993419.

        Maybe you placed the line before those for the exit hint?

        In that case it is clear that the exit hints don't work because
        those rules 

        use the name action which has no effect when mkgmap:label:1 is
        already set.

        If that doesn't help, please provide more details.

        Gerd

          Hi Gerd, hi Bernd

          it works because the default style does not name the outer
          segments (intentionally?). My style treated exits pretty much
          the same way, with one addition:

          highway=motorway_link & mkgmap:label:1!=* { set
          mkgmap:label:1 = 'Exit' }

          Deleting this line and so not naming the outer segments did
          the trick. As far as I can tell, line type does not make any
          difference.

            Hi Michael,

please check how the default style uses the hint. I think it works
fine.

              Hi Gerd,
my 1st assumption was that I set the road_speed too high, and the 
routing would "jump" overthe 2nd part to the 3rd, 2nd assumption was to 
use a different line type - changing both things made no difference.

                  Finally found the reason: my style assigns generic names to unnamed
roads, so the segments of a motorway_link were named "GENERIC_NAME",
"EXIT_HINT", "GENERIC_NAME". As soon as a name is present on either the
1st or the 3rd segment the Oregon would use this name for routing (btw,
contrary the my previous posts: the Oregon 450 also behaves like that).

Which brings up this question: why not assign the exit_hint to all 3
segments in the first place?

                My understanding is that the style should be able to use a different
type (not 0x08 / 0x09) for that small 2nd part, so that Garmin uses
the name of it as a hint.
