Please complete the wikipage. One picture/screenshot of the map on a garmin device would be nice. --John07 11:21, 18 July 2008 (UTC)

I put these on my eTrex Vista this weekend. It does work...mostly, but it would be interesting to document on the main page how you've managed to create these routable maps. Richard B 10:05, 28 July 2008 (UTC)


My eTrex Vista was loaded up with the UK map on Friday night, and I did a journey of approximately 80 miles on Saturday and Sunday. What was interesting was the route it chose - picking a roughly parallel A-road in preference to a motorway for part of the route. Also, it was telling me to go round a couple of roundabouts in the wrong direction. There were also times when I approached a junction such as a roundabout and it gave me no instructions at all - even if I had to leave what was the signed main road. Are these issues with the data, or issues with the way the data has been converted? Is there anything which can be customised? Is it possible to create these myself somehow?

A few thoughts: You can check if problems are in the OSM data or in the conversion by looking back at the OSM data. If it tells you to go around a roundabout the wrong way check the oneway tag and way direction of the roundabout in question. If it makes weird/stupid routing choices make sure the "best" route is actually connected (as opposed to an intersection being 2 nodes very close together), maybe add maxspeed= tags. It could be that the A-road it took you on was a shorter distance to the motorway, but maxspeed= tags are missing so it thought the A-road was faster. Biogenesis

Routing cars along cycle ways: There is a cycle way near my home that leads to a major highway. The map often routes me along the cycle way to get to the highway. The cycle way is tagged correctly, so there seems to be some issue with the map knowing what type of traffic is allowed on a way. Ebenezer 17 August 2008

I downloaded the executable installation kit for Mapsource (all files for the european countries) und installed it to my Quest. I am astonished: it works absolutely fine if you take in account, that this is in an experimental phase! Tbd: street catalogues (Navigation works only to targets, that are searched and marked on the chart. Using the OSM with the Garmin shows me, where something is wrong or missing and i can immediately mark it and use the trace at home for uploading to OSM. Thank you for this nice piece of software!

I'm using the maps for bicycle routing on an Oregon 300 and it works really good - much better than the Garmin CN maps. The reason is probably that the coverage is much better with the OSM maps than with the CN maps in regards of tracks and cyclepaths. What would be really great is if the toolchain to create the maps would be available to the public. This would help speed the map updates and also it would be possible to customize the map to your needs. Here in Germany for example it is not allowed to ride the bicycle on a footpath if it is not explicitly allowed (bicycle = yes), but the maps seemingly don't know about that. Apart from that: this is great work, keep it up! Radfahrer 23:13, 23 November 2008 (UTC)

Today, I tried the German map on my new Garmin GPSmap 60CSx. I was a little bit disappointed. Because when I want to choose the waypoint and put in the city name it couldn't find the city. Then I recognized, I first have to choose the region. It can find the right city only, if the region is set correctly. But here it comes: for Germany there are a lot of regions named: "Germany", "Germany." (recognize the point), "Deutschland", "Aachen", "Bavaria", "Bayern", "Bochum", "Bundesrpublik Deutschland", and so on. As you can see there seems to be a big problem with the source data. There seems to be missing some kind of convention what data to put where in which way. Because with that, it is almost impossible to find a city, in particular if you are not a German. I don't know where to discuss this issue, or if there is already a discussion on this. But with that there is still a lot of work to streamline the source data to make it usable for routed maps (if I assume the same problem exists for other countries as well). --MisterTS 08:38, 31 January 2009 (UTC)

There is a discussion about this on the mailing list.--Extremecarver 19:14, 31 January 2009 (UTC)


It would be nice if the list of objects used in this map could be listed somewhere, like one would have map_features.csv for mkgmap. Also having tracks, cycleways and pathes as tertiary streets isn't needed. Garmin France Topo shows that routing is also possible on trails and tracks. Without this change there could be better differentiation on what polylines to autoroute as a car vs as a cyclist vs as a pedestrian.--Extremecarver 00:54, 22 October 2008 (UTC)

Creating Routable Maps on Linux


Is there any info how to create routable maps with open-source tools under Linux?

Mkgmap works nicely and I'd like to avoid limited cGPSmapper (btw, no version for x86_64 as well). --gour 20:10, 21 November 2008 (UTC)

Mkgmap routing support is improving. For the moment, you'll need to convert your data to polish format (.mp) using e.g. osm2mp, check out the mkgmap nod branch (svn co and compile using something like java -jar mkgmap.jar --route --gmapsupp Feedback on the mkgmap mailing list would be appreciated.
