Worldwide routable Garmin maps: Missing/incorrect feature requests

I certainly agree with you that there should be a good balance between speed and level of detail.
Unfortunately I haven’t had time to fully test the world-test style yet but I will try it out as soon as I get a chance.

Btw, I noticed while driving last night (using the “world” style in my Nüvi) that a road tagged with highway=construction/construction=trunk was rendered as a trunk road. Just thought I’d give you an heads up if this is not already an known issue.

engels? Surely, that’s not a valid tag? Isn’t there also a syntax error in there?

Looks like a typo but I copied/pasted Lambertus’ parameters. If you google on this parameter you will find it anywhere in Lambertus posts. Maybe you have solved another bug!
Have to ask Lambertus when he is back from holidays.

The “name:engels” tag comes from the transliteration step that transliterates non-Latin character sets (well, only Cyrillic currently, but it could be expanded to other character sets like Thai, Arabic, Israeli etc if someone has the knowledge to make the transliteration tables) to English. The application that does this (named: translit) adds the transliterated name as the new tag “name:engels” to the intermediate OSM data before the data is processed by Mkgmap.

This roundabout in Apeldoorn appears incorrect on the Garmin maps:

http://www.openstreetmap.org/?lat=52.18819&lon=6.004571&zoom=18

On the Garmin maps, the outer ring (highway=cycleway) appears the same as the inner ring (highway=tertiary)

Any thoughts on unpaved roads? I’ve seen some discussions about this, apparently there are two ways to tag these:

highway=track (I’ve seen “unpaved” as well, but this seems to be an incorrect value)

or

highway=tertiary (or another classification)
surface=unpaved (or sand, gravel, grass, etc.)

Only the first example apears as unpaved on the Garmin maps. The second example should be marked unpaved as well in my opinion.

That’s because the default styles don’t make a difference for roundabouts in highway types, they all use the same line. In the modified styles I have made a correction.
You can see the changes in the latest test map, because this area is a little larger and it includes Apeldoorn as well: http://code.google.com/p/mkgmap-style-sheets/downloads/list

This is how the test map renders the roundabout now (you can download the mapnik.typ file and rename it to default.typ to see it in Mapnik ‘style’)

That is already covered by the routing. If you set the routing to ‘avoid unpaved roads’, the highway=tertiary road with surface=gravel will be avoided.
You can’t see the difference on the map between a road with surface=gravel or surface=asphalt though.

This is how the mkgmap styles handle unpaved roads:

Flag unpaved roads.

highway=*
& (surface=cobblestone | surface=compacted | surface=dirt |
surface=earth | surface=grass | surface=grass_paver |
surface=gravel | surface=grit | surface=ground | surface=mud |
surface=pebblestone | surface=sand | surface=unpaved |
mtb:scale=* |
tracktype ~ ‘grade[2-6]’ |
smoothness ~ ‘.(bad|horrible|impassable)’ |
sac_scale ~ '.
(mountain|alpine)_hiking’ |
sport=via_ferrata)
{ add mkgmap:unpaved=1 }
(highway=bridleway | highway=path | highway=track | highway=unsurfaced)
& surface!=* & tracktype!=* & smoothness!=* & sac_scale!=*
{ add mkgmap:unpaved=1 }

Excellent, that’s exactly what it looks like!

Installed the test maps and I see you also managed to refill the Noordzee and IJmeer :slight_smile:
Plus this weekend I drove a route where at some point I expected a “right turn” prompt, but I did not get one. With the test map that’s fixed as well.

Right, that’s fine than. Never new the Garmin maps had this kind of info in them that’s invisible on the screen.

Just downloaded the latest map of Switzerland, and the guideposts still show as toilets :frowning:

Thats because this style file is still not in use.

Thanks for the clarification :slight_smile:

Hey might have mis-posted this under the more general OSM Garmin Maps forum.

I noticed that highway=path is no longer rendered on the OSMGarmin WorldWideRoutable .img files I am downloading. Did something change? Could we get highway=path rendered back on the map?

Routeable paths are the bomb.

cheers,

derrick

Maybe this is caused by an upload failure in the last update? Because nothing has changed in the latest styles regarding to paths.

It would be nice to have the style file changes in mkgmap. I am maintaining the mkgmap default style.

Including TYP files in mkgmap is a bit problematic in my opinion. When I last looked at it, there were no open-source tools for creating TYP files. If the TYP files were to be released as GPL, then it would be good to release some text-based source code for them too. For example, a parameterized source would allow one to specify the product-id and family-id easily. If the TYP file is released just as a binary blob, it is hard to track changes in a revision control system, or to record who did what, in particular, where the icon images are coming from. A text-based TYP file would make it easier to automatically import icons from existing repositories.

Marko I presume? :wink:
I work with typviewer which is capable of handling text files: http://opheliat.free.fr/michel40/TYPViewer3.5/

You can have a look at http://code.google.com/p/mkgmap-style-sheets/source/browse/trunk/typ/world-test/default.txt to see if this is workable or not. I don’t know if this editor is open source, you can ask the developer. And otherwise there is Nick’s Typwiz editor, http://www.pinns.co.uk/osm/

I welcome and agree with your comments, skela. We are here doing this because we felt we were not getting adequate responses on the mkgmap mailing list. Feel free to grab whatever suits you. It is all GPL, after all.

When working on the typ files I have had major problems with the text versions, from editors crashing to cgpsmapper not rendering them correctly, so I have come to the conclusion that only the binary version works at this point. I’m sure Minko will prove me wrong now and in fact, I hope he will.

Are any of these style and typ changes in use by Lamertus’s site yet or is site still using the default style?
Is there a plan on when site will start using your mods or are you planning to wait and see if they will be included in upstream mkgmap default style?

It’s working in a test environment using the country server. I still need to prepare the custom map server to use the new stylesheet.
