Re: [Tagging] Dispute prevention: meaning of lanes tag

2012-04-19 Thread Nick Austin
In the UK emergency lanes are called shoulders.

Tags for them have been suggested in the past:

 There is a discussion about PSV lanes, but what about emergency lanes.
 Nobody is allowed to use it, with the exception of people who have to stop
 for a car problem, or by emergency vehicles when there is a traffic jam on
 the other lanes (at least, that's the case in Belgium).

 This is not one place where you can drive to and park your car to change a
 wheel or so, it's a lane along a huge part of the way.

 I think this should be discussed together with the other types of lanes, but
 I won't join further discussion here.

 Cheers,
 Sander

Re: [Tagging] power=tower enhancement

2011-12-14 Thread Nick Austin
The risers I've seen can only be properly identified by close up
inspection, it's generally just a metal half-tube nailed to one side
of the pole through which the cable then passes. Identification of
which poles have risers can only be done by close-up inspection.

However as far as the UK is concerned most of the rural distribution
network is built on private land so only the land-owner would have the
necessary access rights to be able to map risers on their section of
the overhead line..

 I would really like you to expand on why adding
 riser=power_line;tele_communication  would make things difficult to
 map. Though I think it might be hard to visualize making accidental
 deletions a worry.

Hi,

I've heard the term riser used before but only in the context of
getting pipes and cables into tall buildings. I can't offer an opinion
as to whether it's the right term or not.

As far as the UK is concerned this won't help much for many reasons:
1) Poles are often shared with telephone and fibre optic cables and
these also have their own risers.
2) Smaller power lines (up to 11kV) often go down one riser, cross a
road (or other obstruction) then up another riser to continue their
journey.
3) Where three cables meet one of two of them may come up a riser and
it's impossible to tell which is the supply cable and which is leading
to a destination.
4) When underground cables fail they are often abandoned and left in
place. The ends of the cable are disconnected at the top of each
riser.

And finally I think that it's going to be difficult for many people to
verify that the information is correct. I'm not keen on having
information in the OSM database that can only be checked and updated
by very few people.

Nick.

 Hello,

 I would like to propose a new tag on a power=tower (or power=pole) node.
 riser=yes
 to explain that the power line comes up from underground at this tower/pole.

 This would be an equivalent to noexit=yes for the roads, and would allow to
 quality analysis tools to better handle this situation, where a power line
 apparently stops.

 By the way, I'm not a native english speaker. I found this term riser on
 this technical documentation here :
 http://psc.wi.gov/thelibrary/publications/electric/electric11.pdf
 but maybe there exists a better term for this.

Re: [Tagging] Proposed definition for cycleways

 I'll restate it: every way or path *especially* suitable. More suitable than

 Anyway, I'm obviously not getting my message across, so I'm going to have to
 think about how to express it more clearly. I'm not trying to turn OSM into
 a bike project - I'm actually just trying to work out a definition of
 cycleway that people can agree on and that is useful.

The way I see it is that highway=cycleway and highway=bridleway are
legacies from before OSM had access tags (foot=, bicycle-, horse=
etc.).  The original meaning for cycleway and bridleway have
disappeared so now cycleway, bridleway and footway are synonyms with
slightly different defaults for the access tags..

Just to be clear, highway=cycleway is shorthand for highway=footway +
bicycle=yes and highway=bridleway is shorthand for highway=footway +
horse=yes.  There's no need for this definition creep nonsense.

BTW, footway is a bad name.  If OSM was starting over it I'd suggest
that it should be highway=narrowway or similar, used for all ways that
are narrower than a track.

Nick.
