Our friend Никита (user Xxzme in the wiki) put his opinion in the wiki
regardless of the opposition.
Since, as far as I can see, the discussion is still ongoing, I reverted his
changes.

Yes, this is about what I had in mind:
- Either take a section of natural=coastline and overload it with 
man_made=quay

- Or draw a dedicated man_made=quay way on top of a natural=coastline

I have no idea which one would be best. I lean towards the first one for

Speaking of Vatican, i.e. Roman Catholic Church, Mary is Blessed, not
Saint. Her title is Beata Virgo Maria (Beata Vergine Maria in Italian,
Blessed Virgin Mary in English). She is an unordinary Blessed, as she and
her feasts are more important than those of the Saints; anyway, "Saint
Mary" is nothing but a popular name :-)

[Tagging] length=

[Mike Thompson]

I have noticed a "length" tag used on some linear ways [1]. It seems
that this is redundant, as the length could be calculated from the
geometry itself.  It could also be the source of future errors should
someone split the way, for example to add more detailed tagging, such
as varying smoothness.

The length key does have a wiki page [2], but the page doesn't have
much content.  Perhaps it is only intended for nodes?

What do you think?  Should the length tag be used with ways and
relations where the length can be calculated from the geometry itself?
Am I missing something?

I think he was banned from this mailing list for the time being, so he
would have to apologize elsewhere; but I agree that would help make amends.
I would also ask him to avoid making the issues personal.

But to be honest, I don't think it will happen.
He has an history of communication issues in the wiki[1][2], and apparently
in the russian community [3].

I think this discussion got derailed a lot, but I saw some goals:

semicolons; and
(2) what are the merits of semicolons and "indexed" keys.

I recommend we start a new thread to focus on that.

On a node it makes perfect sense. At least as long as it is not

But on a way? Hm... Any real-world examples for me?

Hi Mike,

I don't find it redundant since the length=* tag can give the real length

The way in OSM is only a (sometimes not precise) drawing of an existing

The wiki can be completed with such a nuance.

To be more precise : OSM is based upon a 2D geospatial database.
In my mind, a road climbing a mountain won't have the same length in
reality than in the DB : the Z dimension may have influence too.

Dealing with this problem with a length key instead of introducing a 3rd
dimension in OSM is dirtier but far more simpler ;)

Ok - understood. Although I doubt, that there is real usage for that
example. But I had a quick look in overpass: besides aeroways it is quite
often used on bridges and tunnels, where the actual (official) length can
be observed. Makes sense.

Re: [Tagging] length=

[Yann Kacenelen]

Hi Mike, hi François, hi all,
 
I don't find the "length=*" tag redundant either for linear objects
like streetlines, especially in the case of pretty steep ones: as
they're projected for mapping purposes from 3D to 2D, their actual
length is not the one you measure on the map but you should consider
dividing it by cosinus(A) where A is the angle of inclination between
the local horizontal plan and the linear feature. Pythagore said it, man
;-)
E.g.: a 17-degree mapped mountain road or San Francisco street's will
get its actual length a 5% bonus compared to its real-life counterpart.
Pick a 100-meter-or-more road, it's not just a bunch of cm. Depends on
the accuracy you need, mostly for analysis purposes.

But how to handle it one ways considering splitting and combining ways ?

For bridges and tunnels this info belongs to the area or the relation
but not to an unclosed linear way.

About aeroways we already have an own thread as we have more problems
with them.

How precise is the value of the "length" tag? From what is the value derived?


> To be more precise : OSM is based upon a 2D geospatial database.
In my mind, a road climbing a mountain won't have the same length in
reality than in the DB : the Z dimension may have influence too.

For most highways this will have little difference.  10% (10 vertical
meters per 100 horizontal meters) is considered a steep highway grade.
In this example, the actual road length will be 100.5 meters
(sqrt(10^2 + 100^2)). For ski slopes and aerial trams, yes, it will
have a larger influence.

Perhaps "official_length" or "signed_length" might be more indicative
of what actually is being recorded.

True, but such roads are not very common (17 degree ~= 30%). There are
a few short streets in places like San Francisco that are this steep.
In these cases if someone actually went out and measured them with
suitably precise equipment it might make sense to have some sort of
length tag, but I would suggest something to differentiate it from a
purely horizontal measurement. Of course, you could also drape the OSM
data over a suitably detailed DEM (digital elevation model) to get
your answer as well.

If you need that level of accuracy you may want to consider data
sources in addition to OSM.

In my experience of hiking trails in Ireland, the length advertised
on-site and in leaflets is often 10-20% off (as measured by my treking
GPS that takes relief into account). I expect OSM + SRTM to be more
precise. YMMV of course.

Like Francois said, keep it alive.

The length and width are
perfect keys or tools to determine the size of a bridge, in case of a heavy
load. That the tags don’t have heavy users, too bad, we could do better. But
everyone tags what he thinks is useful.

something ? Considering how well-used man_made=pier is, I am 
surprised that quays get such scant attention. man_made=quay anyone ? 
To quote the IHO dictionary: "quay. A WHARF approximately parallel to 
the SHORELINE and accommodating ships on one side only, the other 
side being attached to the SHORE. It is usually of solid 
construction, as contrasted with the open pile construction usually 
used for PIERS."


So yes, your reasoning is correct & that section of the coastline 
that forms the quay could indeed be tagged "man_made=quay".


Yes, this is about what I had in mind:
- Either take a section of natural=coastline and overload it with 
man_made=quay

- Or draw a dedicated man_made=quay way on top of a natural=coastline

I have no idea which one would be best. I lean towards the first one 
for easier editing - ways exactly on top of each other are difficult 
to select.

Off topic.
http://wiki.openstreetmap.org/wiki/Proposed_features/Harbour#Quay .. is 
dated .. 2008 or before .. 8 years ? proposed? Ridiculous! Abandoned .. 
why? And what is used in its place? Very poor documentation - nothing 
directly on why it failed.




 One could also use waterway=quay or waterway=wharf. This would 
associate it with a waterway, might be a natural feature (think of a 
solid sandstone bank used as a wharf), or man made so why not waterway?  
Does not sit with man_made=pier .. but those don't occur as natural 
features? My thinking is to follow highway=* tagging where traffic 
lights are tagged hightway=traffic_lights rather than 
man_made=traffic_lights. This groups things together for a more logical 
system of things that would be associated all in the one main tag.

As the coastline in some places is man made .. I'd much rather see 
coastline as waterway=coastline rather than natural=coastline. This 
comes back to my thoughts on OSM tagging philosophy/thinking/order ...

True, but such roads are not very common (17 degree ~= 30%). There are
a few short streets in places like San Francisco that are this steep.
In these cases if someone actually went out and measured them with
suitably precise equipment it might make sense to have some sort of
length tag, but I would suggest something to differentiate it from a
purely horizontal measurement. Of course, you could also drape the OSM
data over a suitably detailed DEM (digital elevation model) to get
your answer as well.




Or you could tag the slope/gradient of the road .. I've tagged a short 
section of my street at 17% .. that is averaged .. it peaks at 23%. You 
can then use that to work out the travelled distance, height gained/lost 
etc.


As for tracks being out by uptp 20% .. that is faily normal expection on 
outback roads .. they are dirt and if the grader driver (or his boss, 
the local farmer etc) think it would be better off over there .,. then 
that is where it goes .. can add some distance to what is on the map or 
road sign. I've come across a road that was realigned in such a manner 
for over 100 miles.

Re: [Tagging] patron saints

Probable all christian churches (buildings) and most chapels are dedicated
to patron saints.
E.g. the Basilica Sancti Petri (Saint Peter's Basilica) in Vatican City is
obviously dedicated to Sanctus Petrus (Saint Peter). As in this example, the
patron saint is often part of the common name of a church. But this example
also shows that an automated extraction is almost impossible.


This depends upon which branch of Christianity you are talking about. 
Many Protestant denominations do not recognize the existence of saints 
in the Roman Catholic sense of no-longer-living humans who serve as 
intermediaries between living humans and God.  We colloquially refer to 
some of the early church leaders as saints, referring to Saint Peter or 
Saint Paul, but feel that prayers should be directed to God, not to any 
lesser being.

[Tagging] RFD pipeline sub tag substance

[Warin]

Request For Discussion

http://wiki.openstreetmap.org/wiki/Key:substance

Pipe lines currently exist for non drinking water in various part of the 
world. And have done for some time. They are becoming more numerous as 
efforts to save water and reduce environmental impacts increase.


Unfortunately this does not have a tag for non drinking water .. 
possible values could be


non-potable_water

grey_water

Not recycled water as that is too restrictive .. it could be from a 
river/lake that is not suitable for drinking. Or even rain water that 
has not been checked for drinkablity.


I note that"if the medium of a pipeline you are tagging is not listed 
here, please choose a meaningful value at your own discretion."However 
that will lead to multiple values all meaning the same thing or be too 
restrictive.



Should this be a 'RFC' as in a request for comment?

According to taginfo the values in decreasing use are water (30%), gas, 
heat, sewrage, oil, hot water (20%), electricity (should be 'cable' 
according to the wiki), sewage (3%), oxygen, coal, lng, fuel.


I note This tag has a status "unspecified' .. that probaly means it has 
not been voted on here.
