[OSM-talk] Nature Trails (was: No_comments=yes)

>How can you tag a way with "route_ref=xyz1" and "route_ref=xyz2" at the 
>same time?

You can't.   Either it would have to be the sugestion of haveing many ways, 
or many routes would have to be placed under the key.  so "route_ref="Green 
Route"; "Red Route""

>But I presume you were speaking of creating a second segment alongside the

Agreed.  It's a messy solution, but its would work visually at least.

>some 10, 20, maybe even 50 metres away from each other.

Well it wouldn't be that far, but I see your point.

No I didn't say to scrap information. I said that the time expected to amke 
a walk can be worked out from additional information.  The fact that a 
suggested walk is there cannot be worked out from other data.   If there is 
information on a sign saying time expected=50mins, then by all means it 
could be added, but I was saying that I don't think us estemating a time is 
worth it becasue on many trails there are too many variables.  If I did a 
trail on bike in august it would be differnt to doing it on food after high 
rain fall.  Sticking ''suitable for elderly=no'' is not what i suggested.  I 
just said it 'could' be an option to stick where a route is particaully 
steep just as mapping companies do on roads.   This may just be something 
that people look out for when planning a walk.  It is not up to us to judge 
weather the old person can hack it, its just a matter of informing them its 
there.  This is just the same as sticking primary=motorway.  If people have 
a phobea of motorways the tag will make the nessesery things render to 
informthem.  I wasnt suggesting adding motorwayphobea=yes.

>The way your argument goes, why not ditch nature trails altogehter and let 
>the computer work out the suggestions?

Nope.  All I said was its not needed to add an approx.

All i'm asking is for suggestions as to how to render multple routes next to 
each other, and what would be a suitable tag to use for marking trails.  I 
gave my suggestion, and am requesting better or approval.   I don't really 
want to have a pointless ML-style debate on the matter.
