Worldwide routable Garmin maps: URL REMOVED

mapper_07 · 2013-07-06 08:07:08

in my case i think the network is complete and fully connected. (Because Vienna - Innsbruck; Innsbruck - Verona are working but not directly Vienna - Verona) As i have seen in the style file motorway links are currently class 3. So maybe they should also have road class 4? Also maybe add primary roads to class 4 to get a main network.
For my feeling also the routing currently is not always preferring highways and routes instead on primary roads because they are shorter. (For example Vienna where the nuevi mostly routes on the primary roads instead of going the longer, but faster way on the motorway. Is there the maxspeed and the number of traffic lights included in penalizing these roads on the link weight? Average speed on motorway is 80kmh where on a typically inner city primary road with intersections and traffic lights it is 35kmh.

There are many problems to consider.

First is that Mapsource calculates differently then current version of BaseCamp. Older nuvis calculate different then current models. You can get route on one device and failure on other.

Short distances are calculated differently then long distances.

Network could be complete but too complicated to calculate long route. Network with long roads is easier to calculate than the same network divided into more short roads.

Speed is included in calculations, probably crossroads and turns too. I don't think traffic lights are included but you can decrease speed of road with lights.

You can experiment with motorway_link. I think class 4 could help.

no change with class 4 for motorway links. i also tried additionally to increase primary roads to class 4 to get an austrian wide network but he fails calculating the route every time for routes for ex from vienna to bregenz, or vienna to innsbruck (without having the motorway over rosenheim in the map such that he can route over the "große deutsche eck") maybe i have a problem with the style file because when i removed the line concerning tracks, tracks are again visible and routeable in the map, normal behavior?

popej · 2013-07-08 18:08:44

What program or device are you using? I think Mapsource should be able to calculate your routes but latest BaseCamp has a bad routing, not suitable for OSM at all.

I'm experimenting with routing network in Poland. I have set class 4 for following roads:
motorway and motorway_link
trunk, trunk_link
primary and primary_link with valid int_ref
primary and primary_link for selected national roads
roundabouts with above road types

With these settings I can get working routing across whole country. I think that other countries could have other requirements, depending on their roads network, since too many roads with class 4 is a wrong solution too.

I use a nüvi 205 and 1390. Currently i'm not able to include my maps into MapSource ... I think my mkgmap run didn't include my changes made to lines.

popej · 2013-07-11 16:17:14

See how looks class 4 in Europe, won't be easy to make it usable.

extremecarver · 2013-07-13 08:33:29

Well, what about putting class 4 either for highway=motorway plus motoway_link, plus trunk and trunk_link - and then additionall all streets with an E-Number. I think E-number relations are quite complete in OSM, aren't they?
Plus for GB add the Eurotunnel and the ferry as class 4 routeable.

mapper_07 · 2013-07-13 10:40:08

Good idea! I played around with class 4 for motorway_link and trunk_link and got a better routing in austria on my nüvi 205

popej · 2013-07-13 11:46:58

International primary roads should be include, especially for East Europe. They are red on this picture.

Hi Lambertus,
Can you have a look at the overview map, it is still not included in the maps (overview maps are empty).
I think the ovm_*.img's are not processed during the 2nd step of your map generation and deleted after the 1st mkgmap step?

tanguero · 2013-07-16 18:47:26

Hello: Plz tell me how can I download a 2nd map to use it with Mapsource,
because when I tried, the .exe file of the 2nd map erased the 1st one
I want to download Italy and France files for Mapsource
Thxs in advance

@tanguero
You need the Javawa GMTK tool, see http://forum.openstreetmap.org/viewtopic.php?id=15431

After installing the map of the Netherlands on my Garmin Dakota successfully, i tried to install Italy and France as well. But the Dakota does not see these new maps. Basecamp on the other hand does sees these maps?
Is this a know problem? and how to solve this?

ligfietser · 2013-07-18 09:04:52

Those maps have the same Family ID so the Dakota sees them as one. Only problem are the overlapping map tiles from Italy and France.
You have to select a custom Italy/France map on the website to solve this problem.

I just had a look at this and dicovered a bug in the scripts. In addition to the *.img files I now also added the ovm_*.img files to the commandline of Mkgmap when the gmapsupp.img is and NSIS installer script are created. I requested Albania but don't know how to determine if the overview map is created (it doesn't seem to be the case) I'd like someone who knows more about the overview map to check this please...

I have downloaded Mac version. Overview map is correct, it has multiple layers. Last one is empty, maybe you should move national borders and capital cities up to resolution 12.

Lambertus · 2013-07-18 20:37:15

Great, thanks popej, then every newly requested country map for the generic_new and openfietsmap_lite map should come with functional overview now. I'm not really sure about the generic map.

The generic is still empty, the generic new looks ok (I agree it needs some fine tuning).
In the generic option style file there should be these two lines, thats all mkgmap needs to know

levels = 0:24, 1:22, 2:20, 3:18
overview-levels = 4:17, 5:16, 6:15, 7:14, 8:12

Is it possible to add the ovm_*.img files to the osm_generic_tiles.zip file? This makes it possible to create an overview map when combining several mapsets with the osm_combi tool (there is now an improved version by javawa: http://www.javawa.nl/osmcombiner_en.html). If those ovm_*.img files are not present, the overview map will be empty (which is after zoom level 3 / resolution 18)

Hmmm. These are already in the generic option file. I wonder if the style files are included properly...

Yes, that's possible. I'll add these.

Dear all,

we're gonna have a power outage in the computing center hosting the custom server the weekend

Friday, September 20th around noon until Monday morning, September 23rd.

Some large power transformers need to be maintained which (obviously) cannot be done while the center is powered.

Cheers

Torsten

Lambertus · 2013-07-21 12:25:37

Thanks for the heads-up Torsten.

Hi everyone,

Im in the UK at the moment using the http://garmin.openstreetmap.nl map in Generic routable style (IIRC) on a GPSmap60CSx. The car routing seems to be ok, but the directions it gives are wrong. It mis-counts the roundabout exits: it asks me to exit the roundabout at the first exit when I have to use the second one. Does anyone else see the same effect?

edit: it seems that these roundabouts were segmented in multiple parts. For the GPS it was probably logical: leave the roundabout at the first exit of this segment...

Does this happen at all roundabouts or only some? If the latter, please give some coordinates.

Segmented: in OSM or in the Garmin img file? If the latter, that is a Garmin requirement: you can't have a road loop back on itself.

mapper_07 · 2013-08-04 15:03:31

there seems to be problems on some roundabouts: (tested on nüvi 205 map generic new beginning of july mkgmap-r2653)
these two aren't recognized as roundabouts for example: http://www.openstreetmap.org/browse/way/24674008 and http://www.openstreetmap.org/browse/way/27364665
where that one the counting is wrong: http://www.openstreetmap.org/browse/way/14986396
coming from http://www.openstreetmap.org/browse/way/27683354 to http://www.openstreetmap.org/browse/way/41532468 he say's it's the second exit (is the first)
at that roundabout counting is also wrong: http://www.openstreetmap.org/browse/way/14986398 comming from west to east counted as 1st exit (is second)
this one isn't recognized at all! eather as right turn or roundabout: http://www.openstreetmap.org/browse/way/14986387
this again isn't recognized as roundabout http://www.openstreetmap.org/browse/way/43791952 (says keep right)

this roundabout is only counted (wrong) from east to north http://www.openstreetmap.org/browse/way/29293978. from east to north it says keep right
