[OSM-talk] keep right! and barrier=*

2009-07-20 Thread John Smith

keep right thinks a node ending in barrier=*, cattle_grid and others I guess, 
where as the road past a lot of these barriers would be access=private and 
usually isn't mapped.

eg http://osm.org/go/ueSEtgYJj--

I don't get the meaning. Could you please rephrase? What is keep right 
thinking?

Keep right shows an error about a way ending near another way.

Thanks for the clarification, especially the permalink.

The issue here is not that the way is ending with a barrier node but the 
fact that in a reasonable vicinity to the ending node there's another 
way. Quite often this means that some mapper forgot to connect the 
ending node to a way. In your example this is indeed a false alert, but 
the rule itself is worth keeping. I found several unconnected ways via 
this very keepright "error".

I'm not saying it's not a valid warning, I'm saying it's most likely not a 
valid warning if the end node being referred to is a barrier=*, regardless if 
it's a grid or gate or whatever.

I disagree. I have had dozens of ways in Bremen alone where someone
mapped the private ways, but ended them at the gate, where in reality
the ways did indeed connect to the public road just outside the fence.

Well what I've described is common for a lot of rural areas I've checked, so 
all that these warnings achieve in these areas is making noise and the more 
noise that exists the less useful something becomes.

Maybe this should be dealt with in a regional setting... ?

+1
that's exactly the point. The existence of a gate is in fact a good
indication _that_ the way will continue on the other side. I agree
that maybe in some less populated / rural areas this could be
different (e.g. access to a pasture).

cheers,
Martin

There's always the possibility of setting noexit=yes on the final node.
