Suggestion for more flexibility in locator part of mkgmap
by Clifford Nolan 19 Sep '12

19 Sep '12

Hi Greg, Just to clarify ... the admin_levels for Ireland described here http://wiki.openstreetmap.org/wiki/Ireland/Boundaries#Boundary_Types don't seem to mention things like village boundaries - there's a big gap between admin_level=8 and admin_level=10. In situations like this, maybe the locator could be more flexible and use other kinds of boundaries too. Regards, Cliff

Problem with huge polygon - vänern sea - sweden
by toc-rox 19 Sep '12

19 Sep '12

Hi all, I'm currently working on a map of sweden. I run into a problem concerning the vänern sea (between Vänersborg and Karlstad). This is an very huge polygon / sea - 10 times larger than the german/swiss Bodensee. Only a small part of the sea will be displayed on the as water: http://gis.19327.n5.nabble.com/file/n5710048/Bildschirmfoto_2012-05-24_um_1… Questions: - Has someone a working splitter / mkgmap configuration for sweden ? - I have set the splitter option "-overlap=10000" - could this be insufficient ?

Address search for Rostock doesn't work
by toc-rox 18 Sep '12

18 Sep '12

Hi all, the address search for Rostock (germany) doesn't works for me. In BaseCamp I see the correct region "Rostock, Rostock, DEU", but no street can be found there. In my Garmin GPSr (Dakota-20) no city with the name Rostock exists - peculiar. I have build new bounds from scratch, based on the current europe extract from geofabrik. Questions: - Does the address search (for Rostock) works for someone ? - How is it possible to verify the bounds and the street entries ? - What's the general procedure to hunt down address search issues ?

Finding administrative areas
by Roger Calvert 08 Aug '12

08 Aug '12

A bit of advice, please, if anyone can help. How can one obtain information on the administrative area (e.g. county) an object is in in the style files? For example, I would like to find out if an object is in Cumbria or Lancashire. Some objects have "is_in" tags, but most do not. Such information should be accessible from the surrounding boundaries. Can I access this information in a style file? Thanks, Roger -- ------------------------------------------------------------------------ Roger Calvert ------------------------------------------------------------------------

Address search issues
by Ralf kleineisel 29 Jul '12

29 Jul '12

Hi, I'm having a hard time getting the address search to work. I have split the area of Germany from the planet pbf file. Then I build the Garmin IMGs with this commandline: /usr/java/jdk1.6.0_24/bin/java -enableassertions -Xmx2048m -jar /data/gps/mkgmap-r2294/mkgmap.jar and this mkgmap config file: ### description=OSM_Germany_Alps country-name=Germany country-abbr=DE region-name=Germany region-abbr=DE name-tag-list="name:mkgmap,name:de,int_name,name:en,name" overview-mapname=OSM_Germany_Alps overview-mapnumber=10000000 latin1 reduce-point-density=4 merge-lines=yes family-id=1331 product-id=1 series-name=OSM_SRTM_Germany_Alps family-name=OSM_Germany area-name=Germany index style-file=/data/gps/mkgmap-style-toponew_test120611/ tdbfile=no route=yes road-name-pois=0x640a add-pois-to-areas make-opposite-cycleways=yes remove-short-arcs adjust-turn-headings link-pois-to-ways bounds=/data/gps/boundary/bounds/ location-autofill=bounds,is_in,nearest generate-sea=extend-sea-sectors,multipolygon,close-gaps=1000,floodblocker,fbgap=200,fbthres=20,fbratio=0.5 mapname: 10000001 description: FR-Besancon input-file: 10000001.osm.gz ... [more mapname/description/input-file lines] ### The directory /data/gps/boundary/bounds/ contains the unzipped file http://www.navmaps.eu/wanmil/bounds_20120401.zip The "lines", "points" and "polygons" files in my style contain the top lines from the default style which set the location tags AFAIK. I make the mapsource files afterwards: ### description=OSM_SRTM_Germany country-name=Germany country-abbr=DE region-name=Germany region-abbr=DE name-tag-list="name:mkgmap,name:de,int_name,name:en,name" overview-mapname=OSM_SRTM_Germany overview-mapnumber=10000000 latin1 series-name=OSM_SRTM_Germany area-name=Test family-id=1331 product-id=1 family-name=OSM_Germany index tdbfile=yes input-file: 10000001.img ... [more tile files] ### When I try the address search in mapsource I get this: City search for "Berlin": Berlin is found, but mapsource displays "Berlin, NOT_SET, DEU". When I search for a street in Berlin (say, Alexanderstrasse, I can see the POI on the map) I cannot enter "Berlin" in the City field. As soon as I enter the "i" mapsource deletes it again. When I enter the postcode (10178 for Alexanderstrasse, Berlin) the street is found. Mapsource displays "Alexanderstrasse, Not_Set, NOT_SET, DEU". I tried this for various cities and streets. When I build a gmapsupp.img it behaves rather the same in my eTrex Legend HCx. Any ideas? Is there anything wrong with the bounds data or the style files?

mkgmap crashes if nodes are missing
by NopMap 29 Jul '12

29 Jul '12

I have been debugging a crash of mkgamp where it fails with the exception java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.ArrayList.RangeCheck(Unknown Source) at java.util.ArrayList.get(Unknown Source) at uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation$JoinedWay.<init >(MultiPolygonRelation.java:2199) at uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation.joinWays(MultiP olygonRelation.java:245) at uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation.processElements (MultiPolygonRelation.java:763) at uk.me.parabola.mkgmap.reader.osm.ElementSaver.addRelation(ElementSave r.java:166) at uk.me.parabola.mkgmap.reader.osm.xml.Osm5XmlHandler$SaxHandler.endEle ment(Osm5XmlHandler.java:182) The reason seems to be inconsistent data: a way without the nodes it references. As mkgmap siletntly drops missing ways, but crashes on missing nodes I assume this is a bug. This can be fixed by changing Osm5XmlHandler, line 263 to if ("way".equals(type)){ el = saver.getWay(id); // remove ways without points if( el != null && ((Way)el).getPoints().isEmpty() ) el = null; } Maybe someone would like to apply this fix to make mkgmap more robust. bye Nop -- View this message in context: http://gis.19327.n5.nabble.com/mkgmap-crashes-if-nodes-are-missing-tp571181… Sent from the Mkgmap Development mailing list archive at Nabble.com.

My involvement in mkgmap and the default style
by Marko Mäkelä 27 Jul '12

27 Jul '12

The mkgmap default style has not been changed much ever since the current style language was implemented. I was appointed the maintainer a couple of years ago, after I had submitted some patches. I am sorry for my low level of activity around mkgmap in the past year. I started refactoring the default style, but I had to suspend that, because I got too busy at my day job. Two weeks ago, I made the deadline and started vacation from work, but not from family. :-) I think I could pick up where I left with regard to splitting the default style, some time in August or later. Long term, I am going to escape the Garmin world. The USB interface on my Edge 705 died last October or November, so that I can no longer transfer any saved GPS traces to the computer. So, I bought myself a SonyEricsson Xperia Active for replacing both my GPS receiver and a decade-old dumbphone. There was some initial firmware trouble, but now with the SportyPal bike mount and OsmAnd 0.8 I am satisfied. The GPS accuracy may be slightly worse than that of the Edge, but the Bing aerial image coverage largely compensates for that. Battery life is not a problem, thanks to my DIY dynamo-powered USB charger. Also, I like the offline vector maps and offline routing that OsmAnd 0.8 supports. The bicycle routing might currently be even worse than Garmin's if possible, but the map display will not freeze while recalculating, and I get spoken turn instructions, even for following a GPX trace. I wonder if it would make sense to share some front-end code and area (boundary) processing code between mkgmap and OsmAndMapCreator. Both have been written in Java, after all. I have deliberately tried to avoid touching program code too much, because I get enough of that in my day job (writing C and C++). Even if I will likely not be using Garmin maps much, I plan to keep updating the map of Finland at http://www.polkupyoraily.net/osm/ (and fixing any issues reported by mkgmap) until someone else volunteers. Best regards, Marko
