building=house without addr:housenumber
by Gerd Petermann 10 Jun '24

10 Jun '24

Hi all, for OSM mapping purposes I like to have the possibility to add a poi for each residential (house,apartments,farm,...) building polygon that - doesn't have a addr:housenumber=* tag AND - doesn't contain a node with addr:housenumber=* AND - doesn't have a node on the outline (part of the way) with addr:housenumber=* I want to render a POI with a text like "Hnr ?" so that, when I cycle near such a building, I can decide whether I try to find out the house number. I think there is currently no way to do this with mkgmap since we don't have something like a "contains" style function. I can't remember if we even thought about this when the is_in function was added? My current work around is to use JOSM as a preprocessor but that works only for small maps. Gerd

Commit r4921: fix split() so that there are no gaps between the 4 children
by svn commit 10 Jun '24

10 Jun '24

Version mkgmap-r4921 was committed by gerd on Mon, 10 Jun 2024 fix split() so that there are no gaps between the 4 children With high precision coordinates, some points were not added to the tree because they were within this gap. This quadtree implementation is only used by the flood blocker code which is not used when precomp-sea is used. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4921

Germany specific rule for Fahrradstraße traffic_sign=DE:244.1
by Gerd Petermann 02 Jun '24

02 Jun '24

Hi all, the default style doesn't know about the tag bicycle_road=yes. In Germany, this is signed with traffic sign DE:244.1 . The meaning - without further signs - is bicycle=designated maxspeed=30 vehicle=no There is an ongoing discussion in Germany about the mapping. I wonder if the default style should be changed to evaluate the bicycle_road=yes tag? We would probably need country specific rules. ciao Gerd

Wrong route on roundabout
by Oskar Ohakas 30 May '24

30 May '24

Hello, I compiled my first gmapsupp.img and on test drive garmin offered an obviously wrong route on a roundabout (garmin.jpg). On OpenStreetMap i get the same wrong route with algorithm Car (Valhalla), but Bicycle (Valhalla) and other routing algorithms will give the correct route. https://www.openstreetmap.org/directions?engine=fossgis_valhalla_car&route=… I followed the instructions from https://wiki.openstreetmap.org/wiki/Mkgmap/help/How_to_create_a_map mkgmap \ --route \ --add-pois-to-areas \ --bounds=bounds \ --index \ --gmapsupp \ 6324*.osm.pbf Have I missed an important option? Is it possible to fix the problem in compilation phase or is it something confusing for Garmin algorithm in OpenStreetMap data? If it helps, then I have uploaded the gmapsupp.img for possible inspection to the address https://0x0.st/XNpC.img/gmapsupp.img Any helpful insights are welcome. Oskar Ohakas

arabic translation to latin
by Thomas Morgenstern 29 Apr '24

29 Apr '24

Hello at All, in some tiles from africa are only name-tags as name:ar=<anywhat>. Example : OSM -ID 786.582.586 : addr:street= <arabic chars> ; amenity=hospital; healthcare=hospital; name:ar=<arabic chars>. If I compile this tile with code-page=1252, there shows up as name very cryptic like _/Mstshf ~?Lt?Hyl. /_If I use codepage=65001 ,then shows up the original arabic chars. But I am not able to read arabic. Because that I am looking for a solution to automatic translation from arabic to latin. mkgmap includes already a translation-table. But this table do not contain arabic. Can you give me any hints for integrating arabic to latin ? How to expand this table? It should contain also arabic. thanks thomas

UBUNTU JVM
by Thomas Morgenstern 15 Apr '24

15 Apr '24

Hello, under W10 ,32 GB RAM, Ryzen 7- 8 Core, mkgmap-r4919 (and also previous versions) stops processing large data sets after about 600 tiles. That's why I installed an UBUNTU 22-04 system. And the java-1.11.0-openjdk, installs jdk-21-oracle-x64 and jdk-22-oracle-x64 machines. None of the JVM works. On java-1.11.0, Ubuntu crashes completely after starting mkgamp. Under jdk-21, mkgmap creates ~40 tiles and the terminal exits. Under jdk-22 mkgmap creates ~40 tiles and the terminal closes. Which JVM on UBUNTU needs to be installed to fix this error? Under Windows 10, the generation ends after ~ 600 tiles from 1215 tiles. Why? What do you have to set up on W10 to make mkgmap work to the end ? Half a year ago, this went without any problems. Now it doesn't work on W10 or Linux. Hints very welcome. thomas

Patch to update documentation for splitter
by Gerd Petermann 08 Apr '24

08 Apr '24

Hi all, the attached patch adds a hint that holes in *.poly files are ignored. It also adds the --polygon-desc-file option in splitter.txt. Unfortunately I don't know how to test the formatting in the various formats, esp. the man page. Would be nice if someone on a linux system could test this. Gerd
