Re: [mkgmap-dev] Strange long distance routes on Nüvi

Hi, I think TMC is supported only by NT maps. There should be TMC ID somewhere in img and there is additional file with extension *.trf in mapset, similarly like global index. It would need a lot of revers engineering to find how it all works. And there is not much TMC data in OSM. Probably only in Germany. I have done some work in my own styles to improve long distance routing. This include recognizing international roads and increase of road class for junctions. I will try to prepare a patch for default style. -- Best regards, Andrzej
