Hi WanMil, Thanks for looking into the problem. I wonder if there is a link somewhere to explain how to apply patches.

Could you please test the patch and send me some feedback? Thanks! WanMil
Hi WanMil,
Here are two main examples of what is happing in various locations when viewed in mapsource. Also happens with coastline if it shares a way.
Here are 2 ways from the state border New South Wales/Victoria with an Admin level of 4. The problem is when the first way reaches an intersecting way of a different Admin level of 10.
The state border stops at Node id=360491546 and doesn't continue past the intersecting way.
Way id=32120546 Admin level 4 Way id=32257156 Admin level 4
Way id=32120728 Admin level 10
The border relations are 80372 and 80371
Here is another example of the problem with another state border of Queensland/New South Wales. With these, the problem is also there even though the admin levels are in the ways and relations.
Way id=31954430 Admin level 4 Way id=31954265 Admin level 4 Way id=32300702 Admin level 4
Way id=32296848 Admin level 10 Way id=31954436 Admin level 10
Common node for 5 ways are Node id=357892114 and Node id=357892119
One thing also to point out is the missing ways of the borders are viewed when zoomed right in but the name of the border is missing as a feature and only the lower admin levels names are there as features.

Markus_g

Hi Markus,
I think this problem arises due to a mixture of an mkgmap bug in the multipolygon processing and the broad mixture of how multipolygons are tagged. Some mps are tagged only in the mps, some do have the same tags in the mp and on their ways, some have tags in the mp and only some ways tagged and some mps only have relevant tags on their ways. This makes it quite complicated to handle all cases correctly.
I will need some time to fix one bug I have found in the mp processing. Can you post me some of your problematic mp ids? This makes it easier for me to test my bug fix. One note: --generate-sea-:no-mp should be --generate-sea:no-mp
Have fun! WanMil
Hi WanMil,
Without the --process-boundary-relations I don't get a number of national parks that I imported to OSM for South Australia. These needed to be relations due to there size and a number of them had multiple looped ways.
The problem also seems to be there from the maps supplied from http://garmin.na1400.info/routable.php
They also now use the --process-boundary-relations as I pointed out that this option was new and now appears it is needed for relations.
I mentioned this after other users were missing boundaries that were there before the option was added.
Regards,
Markus_g

Hi Markus,
I have no time now to check that in deep (will do that later).
Do you really need the --process-boundary-relations option? Without this option multipolygon boundary relations are not processed. I think you only need that in case you have some polygon rules for boundaries in your style file but there aren't some in the default style. I guess removing that option could fix your problem.
Have fun! WanMil
Hi WanMil,
Here are the options I normally use. The style is the default.
Java -Xms2000m -ea -jar mkgmap.jar --nsis --net --route --process-boundary-relations --tdbfile --index --preserve-element-order --reduce-point-density=0 --max-jobs=8 --drive-on-left --check-roundabouts --generate-sea-:no-mp --remove-short-arcs --adjust-turn-headings --extend-sea-sectors --no-sea-sectors --close-gaps=1000 --make-poi-index --add-pois-to-areas -c template.args
And here are the splitter options I use.
Java -Xmx3000m -jar splitter.jar --mixed --no-trim --overlap=5000 australia.osm

Markus_g

Hello,
I have noticed a problem with mkgmap if a way is included in multiple relations and Admin levels are used in the relations.
What seems to happen is that mkgmap chooses the relation with the lowest Admin Level and only will display the way in mapsource when the matching zoom level is reached.
This causes problems such as an example if the way is part of a state border, it will only show up if zoomed right in even though the state border relation has a higher Admin level.
Also it appears to effect coastlines if a coastline is included in a relation with a low admin level.
Regards,
Markus_g
Markus,
could you please post your mkgmap-options? Do you use the default style?
Have fun! WanMil _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
