[mkgmap-dev] Routing Problems in Mapsource

Sat Mar 16 15:08:43 GMT 2013

Steve, thanks for that, I do need glasses!

First routing problem now fixed (could see the change you made to the footway). And I can now route along second problem route. Unfortunately now having autorouting problems with:
http://www.openstreetmap.org/browse/way/39771111/history

This may be down to the foot=unknown tag. See jpeg attached for Mapsource routing problem. At least this time it is just showing a straight line not taking a long way round.

Consider these fixed (I also extended another track that was disconnected while looking into this – seems to be quite a few in this area), I’ll look at my style file to see what may be causing the third routing problem.

Cheers, Geoff.

Strange, I checked for that in JOSM at least I did for the bridleway?!

Perhaps I need glasses ;-)

Thanks for the corrections, I'll give it a test.

Cheers, Geoff

  Hi Geoff, 

  In both cases, the paths were not joined up in the OSM data. I have fixed it now.

    Hi,

    I generate routable maps for walking in the UK, but have come across a couple of problems trying to route down certain ways in Mapsource. These ways do not cross any tile boundaries in Mapsource.

    For some reason the following unclassified highway cannot be routed along. This may be as it contains a gate at one end, but I do not show gates in my rules files for points of interest. Even though I do not show gates does this act as a barrier for routing purposes?
    http://www.openstreetmap.org/browse/way/166723108/history

    lines style file contains the following lines for unclassified highway:
    highway=unclassified & access!=private [0x06 road_class=1 road_speed=1 level 1]
    . . .
    . . .
    # No routing for private road
    highway=unclassified [0x06 level 1]

    The second one concerns a bridleway with no special attributes:
    http://www.openstreetmap.org/browse/way/39771110/history

    I thought at first it was because the bridleway  I was trying to route from contained foot=unknown, so I forced this in the lines style with:
    highway=bridleway {set bicycle=yes; set foot=yes}
    highway=cycleway {set horse=no; set foot=yes}
    highway=footway {set horse=no; set bicycle=no}

    And it is drawn with:
    highway=bridleway [0x11 road_class=0 road_speed=1 level 1]

    I have attached a couple of jpegs showing how Mapsource is avoiding these ways for routing purposes.

    Any ideas?

    Cheers, Geoff.
