 Of course I could bring up the fact that FDR Drive in NYC is spelled
 FDR Drive and  F.D.R. Drive, and F D R Drive, depending on which sign
 you look at. :)



yes, actually it is more common than one would expect, to have different
spellings on different road signs (if you count abbreviations as different
spelling). You could use multivalues on the highway and the single
spellings on the sign objects.

[Tagging] man_made=pipeline - is onewayness implied?

2014-06-20 Thread bulwersator
According to iD editor man_made=pipeline implies oneway=yes in the direction of 
way[1]. It is imho a bad idea, because
- it is not mentioned on 
http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dpipeline
- direction of pipeline may be hard (I mapped some and in every case direction 
was unknown)
- many pipelines are bidirectional

I plan to 
- file bug for removing pipeline from list of oneway tags in iD
- mention on wiki page for man_made=pipeline that oneway=yes or oneway=-1 may 
be applied for pipelines moving material in one direction.

Re: [Tagging] man_made=pipeline - is onewayness implied?

2014-06-20 Thread Bryan Housel
Hi, I’m the one who introduced this change.  I’m happy to roll it back if 
needed.

I think I added pipeline to the list of tags that imply onewayness because of 
discussion here:
http://gis.19327.n5.nabble.com/Underground-Pipelines-td5376988.html

Users can still explicitly tag pipelines as oneway=no if it is known that it is 
used in both directions.  Being in oneway_tags just means that onewayness is 
implied and that the feature is rendered with oneway markers.

Thanks, Bryan

2014-06-20 Thread Bryan Housel
Also, It does say here:
http://wiki.openstreetmap.org/wiki/Proposed_features/PipelineExtension#Pipelines

direction: the medium inside a pipeline usually flows in one direction only. 
make sure the direction of the man_made=pipeline way matches the direction of 
the flow of the medium.

So my reading of that was that pipelines imply oneway=yes.

 different spelling). You could use multivalues on the highway and the
 single spellings on the sign objects.
Do not think multi-values in names are practical in any way.

You are always better of in adding different spellings/abbreviations as
extra keys.

For the explicit tagging of street signs you can always tag them as node
and perhaps include it in the street/associatedStreet relation.

Still in favor of no abbreviations in names.

Flowing direction does not really work with waterway especially
waterway=canal and it will not work with pipelines.

Better use an own tag like flow_direction=forward/backward/both/none or
similar. This way we will cover all three cases mentioned below.

[Tagging] roles for route=hiking/foot

2014-06-20 Thread fly
Hey

As there was a small thread about themed and educational walking trails
on the German mailing list I had a closer look at the wiki.

I was wondering if it is ok to add a new roles for route=hiking to add
the art_work or information boards and use route=hiking with an
additional tag or better use a new type for these routes with own roles.

Well, I had a look at the route relation wiki page [1] and did only find
route_marker mentioned as possible role except of roles for
public_transportation.

According to taginfo [2] guidepost is missing and route_marker should
not be mentioned as it has only small numbers_in_use and I did not find
any proposal. I did contact the user who introduced it in the wiki,
asking about removing route_marker and putting it into a proposal and
discussion the issue at this mailing list but we did not find a consense
so far probably also caused due to language and technical problems.

So, I ask you about statements/opinions.

Cheers fly

[Tagging] man_made=pipeline - is onewayness implied?

2014-06-20 Thread Rob Nickerson
There's no onewayness for natural gas pipelines. They may have a
prevailing direction, but the direction of flow is not determined by the
pipe. It's determined by the pressure differential (gas will flow from high
to low pressure) and this can be changed via use of compressor stations.

A natural gas pipeline should not be tagged as oneway.

Re: [Tagging] man_made=pipeline - is onewayness implied?

2014-06-20 Thread Paul Johnson
I don't believe it's implied, since this situation is the same for pretty
much all but the farthest outreach branches of municipal natgas and water
pipes and electrical powerlines (though potential being the key there).
 Heck, even light rail systems are this way to some extent in many cities;
I must have knocked the oneway tags of the MAX lines in Portland half a
dozen times after I added those tracks before I gave up on that (TriMet's
rulebooks and, heck, even on the ground singage and signals!) clearly
indicate (almost) all tracks go in both directions (the ones that don't are
fairly obvious crossovers near yards, or wash rack tracks in yards
themselves, and I'm honestly unsure on the locations of these save for the
wash racks, and even then, I only have a sneaking suspicion which way
trains move through them; and the 5th and 6th Avenue tracks, are probably
one-way (given the trains run in traffic lanes there), but even then, I'm
not actually sure trains aren't allowed to go against traffic there;  I
know the Yamhill and Morrison tracks definitely do allow travel in both
directions, as I've been on trains on both streets that have gone against
the normal operating direction).

Dear Bryan,

 Better use an own tag like flow_direction=forward/backward/both/none or
 similar. This way we will cover all three cases mentioned below.

+1

Making oneway=yes as a default and make it automatically into the direction 
of flow is not a good solution:

* someone might not know the direction of flow, so just chooses a arbitrary 
direction of the way, which might be opposite to the direction of flow. If you 
have a default like this, you never now if the flow direction known or not.
* as already mentioned, more and more gas pipeline are equipped to work 
reverse-flow. So at least for gas, flow_direction=both will be more and more 
common.
