Mapsource crashes while calculating a route
by Andrzej Popowski 29 Sep '16

29 Sep '16

Hi, I have observed crashes for some time. Mapsource 6.16.3 indicates a bug in module MPL_MAP.CPP. Basecamp reports an error or goes into infinite loop. Now I have extracted minimal source data, which creates faulty map. Removing any road or even a crossing point restore routing. Bug exist in mkgmap r2815, r2857, r2889, r2975 and r2976. Map created by mkgmap r2795 works correctly. I'm attaching here files to reproduce problem: mkgmap.bat - batch, which I have used to create the map, test-a.pbf - very simple OSM source data, route.gpx - short route, which causes a crash in Mapsource. -- Best regards, Andrzej

Gmapsupp Creation broken with current mkgmap.jar
by Felix Hartmann 12 Nov '15

12 Nov '15

I just noticed that my maps don't compile into a gmasupp.img anymore using the newest mkgmap versions. e.g. ftp://ftp5.gwdg.de/pub/misc/openstreetmap/openmtbmap/odbl/velomap/velogermany.exe (you could just unpack if you don't want to install). does not compile into a gmapsupp.img anymore if address search is enabled. Without address search it works. With older mkgmap.jar it works too (even though the map itself is compiled with up to date mkgmap.jar). Error message is: Exception in thread "main" java.lang.NoClassDefFoundError: it/unimi/dsi/fastutil/ints/IntArrayList at uk.me.parabola.imgfmt.app.net.NETFileReader.getRoads(NETFileReader.java:116) at uk.me.parabola.imgfmt.app.map.MapReader.getRoads(MapReader.java:205) at uk.me.parabola.mkgmap.combiners.MdrBuilder.addStreets(MdrBuilder.java:307) at uk.me.parabola.mkgmap.combiners.MdrBuilder.onMapEnd(MdrBuilder.java:180) at uk.me.parabola.mkgmap.combiners.GmapsuppBuilder.onMapEnd(GmapsuppBuilder.java:149) at uk.me.parabola.mkgmap.main.Main.endOptions(Main.java:567) at uk.me.parabola.mkgmap.CommandArgsReader.readArgs(CommandArgsReader.java:128) at uk.me.parabola.mkgmap.main.Main.mainStart(Main.java:134) at uk.me.parabola.mkgmap.main.Main.main(Main.java:105) Caused by: java.lang.ClassNotFoundException: it.unimi.dsi.fastutil.ints.IntArrayList at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 9 more With an mkgmap.jar version (trunk) of 1.7.2015 it still works... -- Felix Hartman - Openmtbmap.org & VeloMap.org Floragasse 9/11 1040 Wien Austria - Österreich

feedback on sharp-angles-v4.patch?

Hi all, I am still waiting for feedback from Felix, but maybe other are willing to contribute? See http://gis.19327.n5.nabble.com/Patch-v4-sharp-angles-tp5854127.html Gerd

Commit: r3649: sharp-angles-v4.patch with small modifications
by svn commit 27 Oct '15

27 Oct '15

Version mkgmap-r3649 was committed by gerd on Tue, 27 Oct 2015 sharp-angles-v4.patch with small modifications - remove the code for --adjust-turn-headings which no longer worked - add code to fix sharp angles (enabled by default) Enlarge sharp angles at road junctions so that the time penalty is smaller. In OSM, junctions are often drawn without reflecting the exact angles of the roads, they are more symbolic. We assume that in most cases an angle below 45° doesn't really exist as such and therefor the heading values of the arcs are modified so that the Garmin routing algorithm "sees" a less sharp angle. If needed, the option --ignore-sharp-angles can be used to disable this.

Commit: r3648: fix possible "internal error, road links are not correct " message
by svn commit 26 Oct '15

26 Oct '15

Version mkgmap-r3648 was committed by gerd on Mon, 26 Oct 2015 fix possible "internal error, road links are not correct " message This is related to addr:interpolation ways which connect addr:housenumber elements which specify a street name and the closest road doesn't have that name. Under certain circumstances the assigned road is changed, but another reference was not updated. The fix addresses two problems: 1) Only change the assigned road of such a housenumber element when the alternative road has the wanted name. 2) Always change both references. There is probably no golden rule here, as the data is wrong, and one has to decide if it is better to ignore the addr:housenumber element just because the addr:interpolation way is wrong.

[patch v1] don't route the highway=construction ways
by Gerd Petermann 23 Oct '15

23 Oct '15

Hi all, attached patch implements the new internal tag mkgmap:add-to-NOD=false to handle the issue discussed here: http://gis.19327.n5.nabble.com/don-t-route-through-highway-construction-tt5… It shows how to use it in the default style. I've also added a rule to ignore highway=planned like highway=proposed If you don't like the rather technical name mkgmap:add-to-NOD, please let me know it, here are my ideas for alternatives: mkgmap:ignore-for-routing=yes mkgmap:routable=no mkgmap:address-search-only=yes Gerd

Anyone know why the following lines are included in the LocatorConfig.xml under United Kingdom? They seem to me to be incorrect: <variant>Great Britian</variant> <variant>Gibraltar / United Kingdom</variant> Regards, Mike
