routing support in mkgmap has improved enough that I now have a sort of usable routable map of Berlin on my Vista HCx. Routing is not always ideal, and there’s some crashes in MapSource, but things seem good enough that this might be interesting to try. Some more testing and feedback would be very useful.
That’s awsome, just in time to match my verbal claims to others that: ‘OpenStreetMap will have opensource routable Garmin maps for the end of 2008’. Just awsome!
The big advantage of Mkgmap is that everyone can use it and the source is available. The routable maps published by others are created with private or closed sourced (commercial) software: cGPSmapper.
I’m getting an error - anyone else have this problem?

It looks like your .mp-file contains a malformed (to mkgmap) node line. It expects these to be of the form
Nodx=i,nid,bd
where x just counts through the nodes in a road, i is the node’s index into the coordinates in the road, nid is the node’s ID, and bd is 0 or 1 depending on whether this is a node on the edge of the map. For example
Nod1=3,240,0
It appears that the bd is missing in your map.
Where’s your .mp from? Maybe it’s legal to leave off the boundary field if it’s zero?
Where can I find the latest build of routable Mkgmap?
I’m using r806 with GPSmapedit, and, although the map I made routes, it doesn’t do it very well.
For example, I have to be 500 meters past the “find” waypoint on my 60CSX before it recalculates. Also it doesn’t detect road intersections although it does route across multiple hiking trails.
I’ve noticed that the IMG file that Mkgmap creates loses some of the information in the MP file it compiles from. The MP file has “Transparent=Y” (to create a transparent map) and the MG checkbox is checked (to detect intersections), but the compiled IMG file viewed in GPSMapedit shoes “Transparent=N” and the MG checkbox is unchecked.
Are transparent maps and intersection detection supported?
looks like the wiki needs updating as alot of the new args for mkgmap are missing
I got the latest from --help
as there seems to be no documentation on some of these
Yeah, I tried to document what I knew but I’m surprised as well that there are so many other options. I guess that’s what you get when you never try the --help option
Question about the “–transparent” argument for mkgmap:
If included as shown above (without the quotes) it doesn’t generate a transparent map.
Is it working? “–transparent=y” didn’t work for me either.
Thanks,
When I try to convert mp to img following error display. How can I convert this file?

Hello, it is difficult to tell without seeing the .mp file, is it possible to
download it from anywhere? Also what version are you using? It appears to be
an older version of mkgmap, perhaps the problem has been fixed in the latest version.
I have succeeded in generating very nice routable Garmin IMG files for Central Asia with mkgmap. When I try to use the same style sheets, only slightly modified, for Russia, neither BaseCamp nor my Garmin nuvi GPS can find street addresses, and streets (highway=*) are identified in BaseCamp as airport runways. Has anyone else faced a similar problem, and does anyone have any thoughts on how I should troubleshoot this?
