[mkgmap-dev] barriers on major roads

Sun Apr 20 11:24:30 BST 2014

Hi all,

I've just fixed a rare problem with barrier=* in r3206.
Now I wonder if mkgmap should really process nodes with barrier=* 
that are at the start or end of one way.

I found many cases in the past where this was a mapping error,
e.g.
If a small way is connected to a "major" road, and the connection node has 
barrier=gate, the current implementation will not allow cars to 
travel along the "major" road.

The wiki recommends to avoid this situation:
http://wiki.openstreetmap.org/wiki/Tag:barrier%3Dgate
says
"Avoid tagging highway intersections as that does not make clear which way has the impediment"

I think mkgmap should print a warning if that is found and ignore the barrier.
OK?

Gerd
