[OSM-newbies] Routing issue

[Ed Loach]

Are you able to send a permalink showing the footpath so we can look
at the tagging. If it is tagged highway=footway and there is not a
car permission tag then I would say routing a car along it is a bug
in the yournavigation website rather than anything you’ve done. The
additional foot=yes I don’t believe is necessary, though I think one
of the popular editors (can’t remember whether it was Potlatch or
JOSM as I switch between them depending what I’m mapping) adds it as
a default when you select footway.

 

With regards roundabouts, I take it from your post you are in the
UK. When mapping larger roundabouts (tagged junction=roundabout) the
direction it is drawn indicates the one-way direction of the
junction. The direction is as indicated by the arrows in JOSM or the
little roundabout symbol bottom left in Potlatch.

 

In the case of mini-roundabouts (where a node is tagged as
highway=mini_roundabout, if I remember correctly) these need the tag
direction=clockwise adding in the UK, as the default is
anti-clockwise. If you look at the Osmarender layer at
www.openstreetmap.org then when you have zoomed in far enough you
can tell the direction of the roundabouts by how they are rendered.
Picking a random example somewhere in the UK, the two here:

http://www.openstreetmap.org/?lat=52.06324
<http://www.openstreetmap.org/?lat=52.06324&lon=-2.7183&zoom=16&laye
rs=0B00FTF> &lon=-2.7183&zoom=16&layers=0B00FTF

are both correctly tagged with the direction tag.

 

I hope this helps

Subject: [OSM-newbies] Routing issue

 

I am concerned that a route from my home by car in
http://www.yournavigation.org/ takes me across a local footpath that
I added in JOSM with the tags foot = yes and highway = footway (I
think I put in the additional foot = yes because, being new to OSM
mapping then, other paths already in the area were so designated.).
If this is incorrect or insufficient to avoid a route by car using
such links, I must change all I have done to date, which is quite
considerable in my local area.  I should appreciate some advice.

I notice, too, that in obtaining a route over a longer distance, it
sometimes appears to go around roundabouts to the right instead of
left, with turn instructions accordingly incorrect.  Clearly,
routing highlights many issues which we who enter data into
OpenStreetMap might not be aware of.  Is there specific advice
written anywhere?
