Worldwide routable Garmin maps: URL REMOVED

Lambertus:

I installed California in MapSource and searched for a few streets and every one of them worked well. Can you provide a streetname and cityname so that I can try to replicate the problem?

But unfortunately address search is still very problematic. On some older devices things work a bit better then the newer (e.g. Nuvi’s) but still not perfect. Improving this has been a slow process and there is not much I can do about that.

See e.g. Mkgmap wiki page and the Mkgmap mailinglist
The main changes since 1625 are:
Continued improvements in the polygon / relation support
Command line options are now checked.
Lots of bug fixes and improvements. 
Major things missing/broken
Routing over several (more than 2) tiles in Mapsource
Address index still not 100% correct (works in Mapsource, in the active tile only on "old-style" GPS like etrex/60CSx/edge, does not work at all on GPS like Nuvi, Oregon)
Overview map for Mapsource empty (a non empty overview map would pan around quicker) 
I’m going back to the stable version (r1867) for the next update and it would be nice if you can test if things are any better.

I’ve recently been using the Canadian maps on my Mac with RoadTrip and a Garmin 60CS. The maps are great, but I’ve noticed the search is incomplete as well. The wiki for mkgmap mentions a --index option to generate a .mdr file that is related somehow to indexing and searching. Am I missing this file? Is there a way to generate it with the map download from the site?

BTW, thanks for a great site and service.

The --index option is used and the .mdr file should be included in the .gmapi. Without these two you would not be able to find anything.

You’re welcome!

On the front page it currently states that “Maps are based on OpenStreetMap data from: 01-07-2011”.
At what frequency does this date change? I.e, when will data from say 04-07-2011 make it to the maps?

Thank you for a great service.
I really appreciate it.

A new version, based on OSM data up to 17-07-2011, is being uploaded at this moment and will become available somewhere today.

I saw on the Mkgmap mailinglist that there is a new (special) Mkgmap version that should really improve the address search (ability to find a street on devices where basic searching is already working, not supporting more GPS devices). I’m thrilled to give it a go for the next update.

Lambertus:

Peter, I’ve confirmed the problem by just looking at the NZ Auckland tile. It’s quite possible that the 180 degree line is the problem, but how and where (i.e. Splitter or Mkgmap). I’ll gather some data to test with and write about this to the Mkgmap dev list.

Funny thing is that I can zoom in normally to 100 km, but one step further and the map disappears. Then, if I move the map to the left (i.e. scroll towards the 180 degree line) the map shows up again and when I zoom in again the map disappears again. This process can be repeated a few times more, but you end up looking at the empty ocean off the east-coast of the Northern Island in closeup.

Thanks for your report.

Edit: Ah, now I see. The problem also appears if you zoom in on the western part of the tile. You can keep zooming in as long as you keep a tile edge visible in the screen, but this doesn’t apply for the top or bottom tile edge; only the vertical tile edges. As soon as you scroll the left or right tile edge out the window the map disappears.

Any progress on this?

Thanks,

Peter

Thanks, got it.
I take it there is no defined schedule for when the data is updated?

Lambertus · July 19, 2011, 8:03am

No, I forgot Sorry about that. I’ll have a look this evening…

Indeed.

Thanks once more for http://garmin.openstreetmap.nl - an fantastic resource.

Is there any way to include contour information, a-la http://www.opencyclemap.org/?zoom=13&lat=-39.43924&lon=-73.18335&layers=B0 ? We’re leaving on a cycling trip soon and it would be quite useful!

Lambertus · July 21, 2011, 9:22pm

I don’t offer a contour layer but some others do, e.g. openmtbmaps. They also have a page about creating your own contour layers.

hello all,
new to Openstreetmap and I have a beginners question I suppose… I downloaded the Netherlands map and installed it. In Mapsource the map appears with all the roads etc. but with lines instead of coloured areas. Also, when zooming in the lines thicken. This last problem is solved by zooming out and then in again. I can’t figure out how to fix the coloured areas problem. Any help much appreciated.

Did you download these maps from garmin.openstreetmap.nl?

nielskris · July 22, 2011, 4:45pm

yes, http://garmin.openstreetmap.nl/

Lambertus · July 22, 2011, 5:46pm

Ok, I was amazed to see water color in the Waddenzee. Didn’t know my maps could do that…

Anyway, I think the shading around the roads is one of the “improvements” made in MapSource over time. Perhaps it is possible to turn them off otherwise it’s better to downgrade to an older MapSource version. The hatched (Dutch: gearceerde) areas are a normal Garmin standard drawing method for filling areas.

nielskris · July 22, 2011, 6:39pm

ok, thanks Lamberus, I didn’t know that was Garmin standard.

It was a nice surprise to me too, water colour in the Waddenzee and even waterways.
Combined with the most recent waypoints (http://www.filo.nl/users/nopoints) I will try it for navigating the Waddenzee, beginning with a trip to Schiermonnikoog.

Thank you for creating and maintaining all this wonderful OSM stuff!

Lambertus · July 22, 2011, 9:08pm

You’re welcome.

You (and others) may note that I hope to be able to offer a marine map in the near(?) future. Please notify me if you know of a marine oriented stylesheet for Mkgmap!

ligfietser · July 23, 2011, 8:07am

The ‘water’ colours in the Waddenzee are caused by the natural=wetland (marsh) tags, not by the sea which is not generated in Lambertus maps. Because he doesn’t render the sea the strange shading occurs (I dont see this effect on my openfietsmap). You can get rid of Garmins default ugly hatched areas by using a typ file, like the optional Mapnik one.

nielskris · July 23, 2011, 9:05am

that would be wonderful. What about OpenSeamap - would it be possible to combine the efforts somehow?

nielskris · July 23, 2011, 9:13am

thanks ligfietser, going to try that.

Lambertus · July 23, 2011, 1:02pm

Thanks for this information ligfietser. I also stumbled upon a previous email from you to the Mkgmap mailinglist which explains it a bit more (I think):

Aargh, so much to work around and keep in mind when working with this Garmin stuff …

Seldom · July 23, 2011, 3:20pm

ligfietser, it the background you are talking about an 0x4b polygon?
