[mkgmap-dev] Incorrect runabout exit indication

Sat Oct 4 08:15:40 BST 2014

Good morning Gerd

We know that Generic Routable (old style) maps compiled by Lambertus's site
work correct.
We know that Generic Routable (new style) maps compiled by Lambertus's site
cause problems.

The test maps you send me. are they all new style maps?

Here are the results of the 4 maps samples you sent me:
**********************************************
v3 - the icon indicating the relative position for exiting the roundabout is
INCORRECT

(a relative position indicating one roundabout exit LATER than the correct
exit)

v4 - the icon indicating the relative position for exiting the roundabout is
INCORRECT

(a relative position indicating one roundabout exit LATER than the correct
exit)

V5 - the icon indicating the relative position for exiting the roundabout is
CORRECT

V6 - the icon indicating the relative position for exiting the roundabout is
CORRECT

Greetings
Johan

Hi Minko,

thanks for the info. I am pretty sure that this "trick" is the cause of the
problem,
but I am not sure if mkgmap can be improved to handle it.

If I got it right, the additional roads with access=no are also handled by
the adjust-turn-headings
option, so maybe they are only causing trouble here.

I don't know if (or how) I can configure my Oregon to show the problem, so
I've created more
test maps for Johan:

v3: java -jar mkgmap.jar --route --index --gmapsupp
--style-file=d:\mkgmap-style-sheets-read-only\styles\world wrong-exit.osm
v4: java -jar mkgmap.jar --route --index --gmapsupp --adjust-turn-headings
--style-file=d:\mkgmap-style-sheets-read-only\styles\world wrong-exit.osm
both with the original style files .

v5: java -jar mkgmap.jar --route --index --gmapsupp
--style-file=d:\mkgmap-style-sheets-read-only\styles\world wrong-exit.osm
v6: java -jar mkgmap.jar --route --index --gmapsupp --adjust-turn-headings
--style-file=d:\mkgmap-style-sheets-read-only\styles\world wrong-exit.osm
both with a modified lines file (removed the "continue with_actions" for the
roundabouts)

@Johan: Please check all 4 versions

Gerd

processed, in order to prevent two routable lines on top of each other:

> Third step (continue with_actions) the highways are rendered, so you can
see a difference in road classes on those roundabouts.
> The default mkgmap style (=Lambertus 'old style') renders all roundabouts
the same.
