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

process-exits vs process-destination
by Franco Bez 08 Oct '15

08 Oct '15

Hi all, is there a way to combine the features process-exits and process-destination in a single style ? Based on my experience process-desitnation does a marvellous job when entering a motorway ( does it also work with also trunk roads ? ), while process-extis is perfect when leaving a motorway or trunk road. For instance the roundabout here http://www.openstreetmap.org/?lat=47.89665&lon=10.64805&zoom=17 has two exits towards the B12. Routing from the "Sudetenstraße" going North (maybe towards Augsburg) I would like the Garmin device to announce "5 th Exit - B12 (München)". On the other hand routing to the South (maybe Kempten) it should announce "2nd exit - B12 (Kempten)". Using process-exits this does not work, it's only "5th Exit - B12" resp. "2nd Exit - B12". I would have to use process-destination instead to get the desired messages displayed. Coming home from the trip, routing from the B12 towards "Sudetenstraße" I would like "exit to the right - Exit Kaufbeuren". Using process-exits this works perfectly. Would I use process-destination I would get "exit to the right towards B12 Verteilerring" or even "exit to the right towards Sudetenstraße" a really useless announcement as the sign on the trunk road reads "Kaufbeuren / Neugablonz / Mauerstetten". So this is why I would like to have an option that combines the functionality of process-exits and process-destination. Do you see any way to achieve this in one single style ? Ciao, Franco

Why is there a code-page in the .typ-file? And - is there a code-page a gmapsupp.img?
by Felix Hartmann 20 Mar '15

20 Mar '15

Hi Everyone 1. Switching to unicode I ask myself If I should also change the typ-file to code-page=65001 - is this only for the case that you want to label a line/poi/polygon using unicode characters - or should any .typ-file that is "bundled" by a unicode map, also be unicode? Does anyone know a garmin unicode map that has a .typ-file? 2. I couldn't notice any change on compiling a gmapsupp.img regarding a code-page set. Is there actually a code-page for a gmapsupp.img? Especially regarding address index. Or is the code-page only for the map.img files themselves? Felix -- keep on biking and discovering new trails Felix openmtbmap.org & www.velomap.org

multi-word street search
by Michał Rogala 18 Dec '14

18 Dec '14

Hello! I've a problem regarding street search. In Poland (and I suppose few more countries also may have this issue) person-named streets can have two forms - long one: Miroslawa Dudka or short one: Dudka there is no standard for tagging such names in OSM. Problem is that Garmin/Mapsource search function is matching names from the beginning of the string, so if I enter "Dudka" it will find all streets named "Dudka" but not "Miroslawa Dutka". Do you have any idea how can I deal with such issue? best regards Michal Rogala

Splitter
by Lambertus 03 Nov '14

03 Nov '14

There is a ~20MB o5m file that needs to be split. But Splitter returns: "Cannot find a good split with exactly 2 areas" I hope a (the) dev can have a look at this? Thanks! The tile is here: http://osm.pleiades.uni-wuppertal.de/garmin/20140703/63240007.o5m See for more info and a link to the o5m file: http://forum.openstreetmap.org/viewtopic.php?pid=434024#p434024

Incorrect runabout exit indication
by SPA 04 Oct '14

04 Oct '14

Greetings First of all, Im not sure if I am following the correct procedure by wring to this email address I found here on the mkgmap site? I use a Garmin Nüvi 55 with primarily maps of Denmark from OpenStreetMap (Lambertus) compiled with mkgmap. I have the latest revision of the Denmark map 09-09-2014. All other maps on my GPS are disabled. There is an error: For example, my journey takes me though a roundabout. It is a straight forward roundabout with 4 exists, 3, 6, 9 & 12 oclock. I enter the roundabout at 6 oclock and should exit it at 9 oclock to reach my destination. The voice prompt of my GPS navigates me though the roundabout correctly take exit number three, bla bla bla HOWEVER, the small icon to the top left of the navigation window on my Garmin, indicating the specific roundabout exit position, incorrectly indicates that I should exit the roundabout at 6 oclock. I find this to be the matter with all roundabouts the small icon to the top left of the navigation window, indicating the specific roundabout exit position, displays an exit later that the actual exit that I need to take. When I use a map from for example NZ Open GPS (http://gwprojects.org/) that compiles maps with cgpsmapper both the voice prompt and the icon indicating the specific roundabout exit position (top left of navigation screen) of my GPS is correct. I am not sure if this is a mkgmap compiler issue or a Garmin device firmware issue? Kind regards Johan

type numbers , again...
by nwillink 24 Sep '14

24 Sep '14

The latest impressively detailed manual tells us that: If the type is not extended, it must be >= 0x0100 for a point, I might be wrong but looking at the img structure I come to a different conclusion: Non extended POIs have their 8th bit set to denote the possible inclusion of a subtype. If so I make the maximum for a non extended POI to be &7F and not &FF as perhaps was implied? '< 0x3f for a line, and < 0x7f for a polygon.' Perhaps explain why non extended lines can't be &40+ ( ie bits used for direction & length of bitstream) Regards nick -- View this message in context: http://gis.19327.n5.nabble.com/type-numbers-again-tp5818050.html Sent from the Mkgmap Development mailing list archive at Nabble.com.

multiple boundary lines
by nwillink 23 Sep '14

23 Sep '14

Hi I've across something interesting when plotting boundaries. It appears that boundary=administrative [0x1c resolution 24] gets plotted 2x ie I examined the subfile and noticed 2 identical bitstreams at different offsets, within the same subfile. Only the lbl pointers are different. I wonder if this doubling is necessary as it increases the img file?
