Dear all,

I wanted to check with you which is the best way to map farmlands

for general crop in one part of the year and left it at rest for the 
remaining part of the year, being actually used as a meadow for 
animals grazing there.


Which would be the best way to tag such area?




landuse=farmland

Optionally add?
description=crop rotation
produce=crop (this is non specific... possibly add detail with 
produce=wheat,barley,crop is specific crops are known?)

comment=crop rotation

When a field is fallow then I would not use farmland=meadow as this is 
incorrect ... unless it is truly used as animal grazing or harvesting 
the plants. Some crop lands are used after harvesting from grazing of 
animals but this is a temporary thing that is a small percentage of the 
time, so I don't map it.. too much to keep upto date and that would be 
confusing for maps that don't update on a weekly basis.

it is not our fault that bicycles are treated differently by the law than 
automobiles or horses. ;)
the tag “bicycle” is not about bicycles as an object, but about the legal 
possibility / right to ride a bicycle.
Typically, people pushing a bike are legally pedestrians. That’s why 
bicycle=dismount and bicycle=no are synonymous, and why neither of them is 
suitable to describe whether you can bring a bike as an object, without riding 
it.

I think the last few messages are pointing us in the right direction,
but let me share some entertaining insights to answer your question.

Under our jurisdiction, a person pushing a bicycle or a moped (mofa)
are specifically mentioned at various key points in the law.
https://net.jogtar.hu/jogszabaly?docid=9751.KPM

The law legally regards you as a pedestrian when you (Appendix 1, II/a):
* push a bicycle,
* push a moped,
* ride a (slow enough) wheelchair,
* push a wheelbarrow,
* push a stroller.

The following road users are regarded as drivers (Appendix 1, III/a):
* person driving a vehicle (except person pushing bicycle or moped),
* person riding/driving/leading an animal.

Pushing a cart seems to be a mixed bag:
* you don't need to hold a driver's license,
* you are not considered a pedestrian, hence can not use the sidewalk
and must abstain from alcohol consumption.

Pushing any other vehicle (e.g., motorcycle, automobile) is considered
dangerous and not recommended, except for moving them to safety until
it can be towed. The pusher in this case is legally considered a
driver, the act itself is legally considered driving the given vehicle
and hence must hold a valid license and must also abstain from
alcohol.

So to sum it up, when you are pushing your car, the same OSM car
access restrictions apply to you as if you were sitting inside and
using the engine. When you are leading your horse, the same horse
restrictions apply to you as if you were riding it (i.e., you should
not lead a horse on public roads when you are drunk because you may
not be cautious enough to protect the animal from causing an
accident).

Exactly, foot=no doesn't mean that feet are not allowed, it means that
using a mode of transportation that primarily uses feet  ("foot
travel"/walking/running/hiking) isn't allowed.
bicycle=no is consistent with this, it doesn't mean that bicycles are
prohibited, it means that a mode of transportation, (bicycle riding) is
prohibited.
horse=no is apparently a  little different as you point out.  It seems to
refer not just to a mode of transportation, but to the possession of the
animal in general.


I disagree. In both cases, what is prohibited is the horse/bicycle 
touching the ground.


Based on that, you could argue that bicycle=no means you can *carry*, 
but not *walk* (push) your bicycle. I would be *tentatively* sympathetic 
to such an argument... depending on how obnoxious it is for you to be 
dragging around a bicycle. For something like a foldable, or if is 
dismantled enough to not be a large, ungainly object, then I would lean 
toward that being okay (which is where we get into prohibited=bicycle or 
whatever spelling).



It is similar to dog=no. dog=no doesn't refer to
whether you can use a dog as a mode of transportation, it means you can't
possess a dog at all on the given way (even if you carry it).


*This* is where things become inconsistent :-). Although, as we've 
noted, in some instances you *can* carry your dog.

Tough call.  In isolation it looks like a parking lane, but it has markings
for car parking.  On-street parking (at least where I am) doesn't usually
have that.  However, when I switch to Virginia imagery (much clearer)
I see the parking extends around the corner.


The Virginia Ortho isn't bad, and I sometimes use it as a secondary 
reference, but MapBox is even better. (That doesn't seem to be the case 
everywhere; in some places, MapBox is apparently quite bad, but for much 
of the US east coast it seems to be the highest-resolution imagery 
available. NAIP is the *newest*, but it's lower resolution than many 
other sources.)



From the geometry, I'd say that was a parking lot.


Currently, I have the non-parallel spots marked as a lot. To my mind, 
parallel parking and on-street parking are nearly synonymous. That said, 
I can see your argument, especially if I look at JOSM's lane rendering 
as a gauge for whether normal traffic flow would be occluded by parked 
vehicles. In that sense, there are a lot of folks parking on e.g. 3rd 
and 4th Avenues (where there are additionally not marked spaces) that I 
would definitely call "on street parking". (I'm also not at all inclined 
to tag that.)



but would you argue that all of Potomac Avenue
(https://www.openstreetmap.org/way/686513005


From the fact that parking spaces are marked, it's not a parking
lane, in my opinion.


Well it's certainly not a parking *lane*; you clearly are not meant to 
possibly drive through it. I was thinking that the fact the parking 
spaces are arranged so as to not occlude traffic was what was inclining 
me to model it as a "lot".


Really, it's the notion of a parking lot for which the aisle is also a 
main road that's throwing me... Maybe I should look at what's been done 
somewhere like Manhattan...



Actually, I did mean the six spaces on the west side of Broadway. I
recommend looking at e.g.
https://www.openstreetmap.org/edit#map=22/38.52057/-77.29185 for all of
those, it will be easier to tell what's centered.


That's a parking lot rather than on-street parking.  At least, that's how
I'd map it.  If no cars were parked you couldn't drive along it without
some turns.  If you mapped the highway itself as an area, that
parking would be a pregnant bulge.


Yeah, that line of thinking is similar in effect to asking if it 
occludes normal traffic flow. Different questions, but likely to have 
the same answer.



This is how I handled a similar one:
https://www.openstreetmap.org/?mlat=52.08562=-4.65829#map=19/52.08562/-4.65829

Somebody objected that whilst that looked right when rendered, when
you examined it in the editor it misleadingly implied that you could
park with one end of your car blocking half of the street.
Well, there's an easy solution to that; map the spaces, also ;-). That 
said, I find that attitude slightly asinine; it's normal for a parking 
lot area to include at least parts of the aisles.



I did one car park which attempted to deal with that complaint:
https://www.openstreetmap.org/?mlat=52.10572=-4.37367#map=19/52.10572/-4.37367
but it looks so ugly that I doubt I'll do that again.


Agreed (on the 'looking ugly'). I also tend to line up edges of lots 
along ways (example: https://www.openstreetmap.org/way/826298876). 
However, part of that was from an effort to make the lot only cover the 
area where you can actually park, without disconnecting it from the ways 
that serve it (the aforementioned lot is a good example of my 'older' 
technique). However, now that I am drawing the spaces also (thank you 
gridify!), I'm generally mapping the entire surface, up to some 
semi-arbitrary cutoff representing the entrances. I suppose if the roads 
were also mapped as areas, I would probably connect those rather than 
mapping them as separate driveways, although I'm on the fence there 
also. For example, with https://www.openstreetmap.org/way/826239218 I've 
connected the parking aisle directly to the main road, but in other 
places (e.g. https://www.openstreetmap.org/way/829371430) I've modeled a 
separate driveway first.


Anyway, your example would be much more sane if the entire road had a 
mapped area, rather than just the little piece by the parking lot.



In the end, do what works for you and hope nobody else who comes across it
thinks it so egregiously wrong that they change it.  At least not until
you've finished your project.


As long as they don't *remove* information, I don't mind people 
fiddling. That said, I'm not going to hold my breath, there doesn't seem 
to have been much activity on the base until I started working on it.


...and to be honest, another argument for modeling as lots is that the 
parking_lane tagging is rather more obtuse...


Anyway, thanks very much for

And now I have the perverse desire to suggest that if bicycle=no prevent
(bi)cycling we should use bicycling=no to prohibit the bicycle itself. But
that would be as terrible as I am currently finding it funny.

I'm happy with it being tourist information.  Well, sorta.  Essentially it's
just information.  But if you lived there you'd know anyway.  So it's
information
for tourists.

But it's not only for walkers and hikers.  Not when it's on a public road.
In the middle of a set of trails, it's for walkers and hikers, travelling at
walking speed, and with time to investigate.  It's also a waypoint for
motorists when it's on a public highway.

Now explain why you feel the need to differentiate a blaze from a
guidepost.  It's all just information about a route.  We could condense
everything into information=route.  In fact, we don't even need that.
Just tourism=information is sufficient because if it's in a wilderness
area next to a trail it's information about the route.  Problem
solved.  It's all just tourism=information.

I suggest that if what is prohibited is pushing the bicycle, then we make
an explicit tag for that bicycle_pushing=no. The same with regards to
carrying the bicycle. If possession is prohibited all together, then
bicycle_possession=no.

I suppose that you therefore consider that the principal tag for these

that the informative function rather than the shape is the important
attribute?

And I guess I had better go back and get a better picture of
https://www.flickr.com/photos/ke9tv/9438767603 because in the photo I can't
really tell whether that's a poorly-set post made from a fallen tree trunk,

it was likely obstructing the trail. (Which would be fine; I haven't
climbed Indian Head in a few years, and it's got a nice view. It'll have to
wait, though, until the local authorities give me a less ambiguous 'green

Yes, I think that would be workable.

Nonetheless, I completely agree with you, =no should mean =no! But I
fear we're in the minority, and that the sloppy tagging of the
past has
a formidable inertia.


I disagree, see my other answer relating to agriculture.

Also, it contradicts the principle of least surprise that most
countries do not have such restrictions, hence regardless of how you
would like to redefine `bicycle=no`, half of the world would still
keep tagging it incorrectly.


As I see it, having bicycle=no imply permission to push a dismounted
bicycle violates the principle of least surprise because it's
inconsistent with other *=no access tags. I wouldn't presume I could
push my car along a motor_vehicle=no way, or dismount my horse and lead
it along a horse=no way.

I'm not asking for a stricter redefinition of bicycle=no because I
suspect it's simply not feasible at this point, especially given the
continued popular support for the interpretation that allows dismounted
travel. But it's clear why there's confusion here. Precisely because of
this inconsistency in the meaning of *=no, the strictest documented
bicycle tag value does not correctly describe the strictest real-world
cases (which are not rare.) And I guarantee that many mappers do not
know that they're implicitly permitting dismounted bicycle travel when
they tag bicycle=no, especially if they're aware of the bicycle=dismount
tag.

At the same time, I fear that defining a new value, stricter than =no
(eg =prohibited, =banned, etc) would probably cause more problems than
it would solve, given the number of data consumers that would need to
adapt to this change. This is why I reluctantly suggested adding a
second tag (dismounted_bicycle=no) alongside bicycle=no, even though it
feels like an ugly hack. Other possibilities might be
prohibited=bicycle, bicycle:prohibited=yes. foot:pushing_bicycle=no,
foot:conditional=no @ (pushing_bicycle)... all pretty hard to love.

Maybe I'm wrong and a stricter-than-no value could be adopted without
too much pain? There is already limited use of bicycle=prohibited. (OSRM
currently appears to ignore it, see

it's not on-street parking (my opinion).  I would class

To me a guidepost is a guidepost, no matter whether it has fingers and a

I think this matches very well the style many other tagging rules are

That may well be true.  And so you see that your square peg is small
enough to fit into the round hole without force being required.  It serves
the same function, as far as you are concerned, so it's the same thing:
information about a trail.

I gave fingerpost examples in my previous post because that's what's common
in my country.  The tag is for guideposts rather than fingerposts, and many
of the wiki examples don't have blades or fingers either.  But they DO
have posts.

You got your square peg through the first round hole, but there's another
round hole, a smaller one, that your square peg also has to fit through.  A
different cultural expectation from the one I think you're assuming.

Here's an example I used to travel past regularly.  But that was years ago,

https://goo.gl/maps/fWvzsKneyMtSAFuW6  I remember roughly where it was,

the fingerpost.  So you'd be looking for a fingerpost.  You might not notice
a rock on the ground daubed with some graffiti.  If you did notice the rock
you might not realize it was the "sign post" you were looking for.  At
typical
driving speeds you probably wouldn't have time to read the graffiti, and
even
if you did read it you might not realize that it was marking the trail you
expected to see a fingerpost for.  You probably wouldn't have looked
where the trail went anyway, as you were just concerned with seeing
a sign post.

Different cultural expectations.  You're looking for information about a
trail and don't care what form it takes.  I'm looking for a sign post and
don't care (unless there's another one close by) what it says or where
the trail leads.

Sometimes 'expectations' turn out, on examination, to be 'cultural
assumptions'. I tend to prefer, where possible, to interpret tags _sensu
lato,_ because otherwise there's a tagging quandary any time something
doesn't fit the definition _sensu stricto_.

In the strict sense that you are advocating. I suspect that my area has
absolutely nothing that you would call a 'guidepost',.

https://www.flickr.com/photos/ke9tv/14276154341 is probably the closest,
since the signs are outboard from the support, but even there, they aren't
finger- or blade-shaped; they are rectangular signs hanging from a
cantilevered arm.

Cantilevered arms are unusual. Commoner practice around here is just to
nail the signs to the support as with
https://www.flickr.com/photos/ke9tv/15541120652 and
https://www.flickr.com/photos/ke9tv/7881561738

Using a post is also uncommon. It's much more usual for the signs to be
placed on whatever is available. Most commonly, that's a tree:
https://www.flickr.com/photos/ke9tv/14276103771
https://www.flickr.com/photos/ke9tv/14092717700 but it can be a utility
pole https://www.flickr.com/photos/ke9tv/6936695538 a building
https://www.flickr.com/photos/ke9tv/14190539728 or some other convenient
surface. (I've seen them on cliff faces, boulders, cairns and bridge
railings, but I don't have photos to hand.)

The common thread in all cases is that there's an enumeration of
destinations, with directions identifying the ways that go to them, and
(usually) the distances to the destinations. I distinguish a guidepost from
a trail blaze in that a trail blaze ordinarily identifies only the trail
you're on - or even just that you're on a trail - and sometimes (more
often, just by implication) the direction to follow.

Depending on the land manager's practice, around me a blaze could be a
simple splash of paint https://www.flickr.com/photos/ke9tv/14018094576, a
generic marker in tin or plastic
https://www.flickr.com/photos/ke9tv/14018066876, a slightly less generic
marker showing a trail purpose such as a spur leading to a campsite
https://www.flickr.com/photos/ke9tv/10282365273, a sign with a route number
(here also augmented with a generic blaze for a snowmobile trail)
https://www.flickr.com/photos/ke9tv/14318057029, or the logo of a
particular trail. For example, in
https://www.flickr.com/photos/ke9tv/7881583380 the stylized AT is the
symbol for the Appalachian Trail, which goes through the crawlway as
indicated by the arrow. The white rectangle (about 5 x 15 cm, long axis
vertical) is the AT's usual blaze. On the sign already shown at
https://www.flickr.com/photos/ke9tv/14092717700, there's a Long Path marker
at upper left, with that particular trail's logo on it. (Its customary
blaze is a 5 x 10 cm rectangle in aquamarine, already seen at
https://www.flickr.com/photos/ke9tv/14018094576.

Usually the only directional indication with a trail blaze will be an
arrow, and it's commoner to indicate the direction by conventional
placement of the markers. In https://www.flickr.com/photos/ke9tv/4988268609,
there are two markers on the tree at right, with the top one offset to the
right, indicating a right turn.

I don't ordinarily map trail blazes unless they're otherwise interesting
for some reason. I make route relations for them.

Sometimes, where a trail crosses open country (farmland or marshy ground)
where there are no stones to build a cairn or natural surfaces to paint a
blaze, a trail will be marked using posts with the blazes marked on them.
Confusingly, the word 'guidepost' is also used in common speech for these,
but I wouldn't use the 'guidepost' tag for them!

I don't think I've ever seen a UK-style finger post on a trail or road
around here.

Actually I could indeed think of a place where you are only allowed to
be present in case you are pushing a bicycle. Imagine a bicycle
adventure park that only contains bicycle roads. Let's say that the
terms of service declares that visitors must not leave their bikes
unattended (i.e., no parking).

Now let's pretend that there's a small bridge in the middle of the
park that includes a small stretch of stairs that has bicycle pushing
rails (or substitute with just a single wooden bridge in a bad shape
that has a bunch of long cracks that could easily lock your wheels if
you ride over it - true story, we had a bridge just like that). A sign
would be posted here that disallows bicycle riders from accessing it,
but pushing through would be possible.

How could you be walking on to this bridge if you were not in
possession of a bicycle in the first place?


Interesting. I suppose the question becomes, if there were such a way, 
would you tag it foot=no + bicycle=dismount?

This should be more applicable in case the person walked by the said

Also, I'd like to stay neutral in this question as of now, but I think
it would be possible to implement heuristic algorithms to reconstruct
the history of a way even if it was split and to walk backwards on
changesets to check where "survey" was also mentioned as a "source".
We had a talk about just this on our local list some years ago.

A little preprocessing could go a long way, and such data structures
could be generated weekly or even less often - as the issue itself is
that a long time has already passed since the said objects were

Alright, I didn't know you were only asking for the entertainment
value, but then I accept your challenge.

Actually I could indeed think of a place where you are only allowed to
be present in case you are pushing a bicycle. Imagine a bicycle
adventure park that only contains bicycle roads. Let's say that the
terms of service declares that visitors must not leave their bikes
unattended (i.e., no parking).

Now let's pretend that there's a small bridge in the middle of the
park that includes a small stretch of stairs that has bicycle pushing
rails (or substitute with just a single wooden bridge in a bad shape
that has a bunch of long cracks that could easily lock your wheels if
you ride over it - true story, we had a bridge just like that). A sign
would be posted here that disallows bicycle riders from accessing it,
but pushing through would be possible.

How could you be walking on to this bridge if you were not in
possession of a bicycle in the first place?

/OFF: Yep, the included whip antenna of an RTL SDR can receive these
beacons from an impressive range.

[Tagging] Map maintenance with StreetComplete - Preferred tagging

2020-07-23 Thread Tobias Zwick
Hello everyone

As you may or may not know, my microgrant proposal "Map maintenance with
StreetComplete" [1] was selected to be funded by the OSMF. So, I am
happy to have the oppurtunity to invest the time  extending the app,
hoping that it will help to keep the map up-to-date and unburden people
and communities invested in that topic.

I am pitching this here because there are three details on which I would
like to hear your input. Two of these are about tagging.

But first, how will it work?


So, what StreetComplete will do is to scan the map for whether certain
properties (tags) of map features haven't been surveyed for a certain
time. If this is the case, users will be prompted to answer the question
for that property again. For example, if the app ascertained that the
smoothness of a road hasn't been changed for 5 years, it would ask users
again about the smoothness of the road.

Challenges
--

Now, you might imagine that this is not so straightforward to implement,
and you would be right, for several reasons:

Firstly, the OSM API has no notion about when a particular property of
an element has last been changed, only for when the whole element has
last been changed. But elements are changed all the time for various
reasons. Roads for example tend to be changed especially often, splitted
up to accomodate bus routes, turn restrictions, when detailing
intersections, etc.

Secondly, there is only the date of the last change, but that doesn't
mean that is the date of the last survey. Even though that would be the
information we are interested in: when has the element last been checked
on-site?

Thirdly, the OSM API does not offer users to record solely that they
checked something and that it is still up to date. Any new record in OSM
must always come with a tagging change.

Solutions
-

In the absence of direct API support, fortunately the community came up
with a solution: Add the check_date tag to the element that has been
checked on a survey - or with the namespace if it concerns only a
certain tag of a map feature.

This works well and is actually already used by Streetcomplete in the
"Is this construction site finished?"-quest:
If the element as a whole hasn't been changed for 6 months *or* the
check_date key is present and its value is older than 6 months, the
quest is eligible to be asked again. When the user answers the question,
the check_date is set to current date.

Your input
==

Now here is where I would like your input:

1. Use check_date:smoothness or smoothness:check_date?
--
check_date with a namespace isn't used all that often yet, both variants
are used and thus there is no real winner yet. What variant do you
prefer and why? And most importantly, which variant would be most
consistent with existing tagging practices?

2. Always record check_date or avoid tagging it where not absolutely
necessary?
---
If something is resurveyed and it is acknowledged that nothing changed,
it is absolutely necessary to tag check_date. If something changed, it
is not strictly necessary because that the element changed as a whole is
itself also recorded.
But as already mentioned, elements can and do change all the time. One
can not assume that if an element has been changed that it has been
checked on-site. And even if one could, maybe not all the things were
checked but for example only the bus route relation, or maybe only the
presence of a sidewalk, or someone made the way a little more detailed etc.

The topic whether StreetComplete should only tag the minimum of what is
necessary to ensure functionality or always tag check_date (at least for
properties that are eligible for re-survey) was already subject to
discussion in the issue tracker here:
https://github.com/westnordost/StreetComplete/issues/1836

Maybe it is obvious that my opinion is that StreetComplete should always
tag check_date as it also adds valuable information for other surveyors
that do not use StreetComplete. Nevertheless, in the GitHub ticket
linked above, I played a bit of a devils advocate for the other point of
view - for being frugal with such meta-tags.

So, I'd like to collect what are the advantages and drawabacks of adding
check_date to all the tags surveyed on-site, with your help.

3. At what intervals should questions be asked?
---
Certain properties can be expected to usually not change in tangible
amount of time. For example, properties such as the structure of a
bridge, the levels and roof shape of buildings, street names and
housenumbers don't or change so infrequently that it is not worth
sending users every once in a blue moon to re-check the data. Others
will change more frequently, such as the smoothness of roads and ways or
anything related to businesses as they close and other shops open in

Transponders on civil aircraft implement a subset of the military
Mark XII IFF system.  This is no coincidence: military aircraft
should treat civilian aircraft as friendly...  Mode S (civilian)
and mode 5 (encrypted version of mode S for the military)
are used by TCAS to avoid collisions.  So civilian
transponders are IFF systems with restricted capabilities.

This is probably not a suitable place to discuss this further.

I cannot think of many roads where you can walk but not cycle, other

All of those examples appear to allow regular pedestrians (foot=yes), 
which is common. I am asking if there are any places where walking is

It didn't make much sense to me with either interpretation, but I assumed

Good question.  But it more closely resembles a guidepost than a blaze.
Whereas the things being shoe-horned into guidepost in this thread more
closely resemble blazes.  Elaborate blazes with text.  Not that I'm
arguing we should abuse either tag by using for other things that
go against expectations.

Since we already have blazes and guideposts, the argument that
we need to ram all the square pegs into a single round hole doesn't
fly.  We've already breached that barrier.  Virgin no longer.

So the question is do we want meaningful tags or misleading tags?

Within the way drawn for the office building, you should place a separate
node for the office POI. This node should be one having the given access=*
tag. Although, I think if I can visit a public office, that usually implies
that I have access to the given building as well, we usually do not add
access=* to buildings.

I don't quite understand what you are trying to get at with the question,
but let me list a few places where I think bicycle=dismount is implicitly
encoded:
* footways;
* "road closed" (unless certain extensions are added below)
https://commons.wikimedia.org/wiki/File:Estonia_road_sign_311a.svg
* within buildings (train stations, subway stations - you are free to carry
your portable bike around here);
* one way streets from the wrong way (should push either on the sidewalk if
it exists or on the road).

Maybe I didn't make myself clear in that sentence. I referenced a statement
from a different tagging thread a few weeks ago.

The gist is that if a mapper encounters a given tag (like
bicycle=dismount), a given definite meaning should be understood. This may
be _refined_ by further tags on the same POI, especially subtags, like
highway=service + service=driveway. Meaning shall not be redefined, rather
made more specific in these cases. However, I can't say that
highway=service + not_really_service=yes, i.e., a certain combination of
independent tags may not carry a meaning that greatly contradicts with any
subset of the said tags.

For example, bicycle=dismount should be understood that bicycle access is
only allowed if a rider dismounts. However, if we had to write
bicycle=dismount + foot=no, then the meaning basically becomes: neither
riding your bicycle nor walking is allowed here, which is quite the
opposite compared to what bicycle=dismount would mean if it were placed
alone on the POI. Hence the correct way to tag this should be bicycle=no +
foot=no.

I really enjoyed Phil's joke and I recommend that you think about it as
well.

These are a very similar situation to the one regarding bicycles that we
are discussing because we have to differentiate between possession of the
item (and how exactly it is possessed - e.g. open vs. concealed carry, vs.
locked in trunk of vehicle of a firearm), and using the item (discharging
the firearm, consuming the alcohol).  For example, it is legal in many US
National Parks to carry a loaded firearm, but in most cases it is illegal
to discharge it while in the park.

You are trying to address a reaIly (numerically) big problem.
I would have thought anything with office=* may need an indication of the
presence or less of customer service.
Most likely anything that is shop=* would implicitly offer customer service.
So for the 700k office=* we need to retrofit an indication, whether they
offer or not customer service.
As I said above, this looks to me like a gigantic task to start with, but I
also see a problem with the proposed tag:
If an office offers customer service I add amenity=customer_service, but
how do I indicate that they don't?
So it would have to be customer_service=yes|no at least.
That would also permit to check which offices have been evaluated by
mappers for the presence or less of customer_service.

But also consider that it wouldn't make sense to tag a motorway as
foot=no + bicycle=dismount (+ moped=dismount + mofa=dismount +
auto_rickshaw=no + agricultural=no), because the combination of tags would
create a completely new meaning, and that is not a preferred tagging
practice in OSM.

I.e., bicycle=dismount means that you can proceed after you dismount,
however if a certain combination of other tags are also present (foot=no),
a data user would need to ignore this, making this more confusing than
necessary (bicycle=no).


I'm trying (and failing) to imagine a road/path/whatever that you are 
allowed to walk on *iff* you are pushing a bicycle (or moped or...). Do 
you know of any examples?

One use that comes to mind, where shop is inappropriate, is my county
council.  It has small (one- or two-person) offices in major towns that
deal with queries, complaints, accept rent payment and council
tax payment, hand out rolls of recycling bags, etc.  It also has
a headquarters with many buildings housing various departments,
most of which do not accept walk-ins (but may invite people to
attend in special circumstances).

Yes, and in such cases shop should be used.

But in some cases where office=* is used
there is no known to me tagging scheme 
covering this, such as car of energy 
company customer service location.

It is place where you may handle overdue
bill payment plans or attaching new property
to power network or dispute bill.

Is there shop tag for that?
At least in my region people always tag
it work office, and it seems to not be
really fitting for shop key.

Could you perhaps use existing tags instead of this?
office=company + access=customers
vs.
office=company + access=private

It is also a confusing term to have chosen as prior to reading your
page I had a Customer Services desk in my mind. Typically this is where
you go to exchange purchases, get refunds.

That is one viewpoint.  It is something indicating the path of a route.
Collect them all under one tag because they all specify that kind
of information, no matter what they look like.  It makes overpass
queries easier, etc.  That's why trail blazes are
information=trail_blaze and not guidepost.  Ooops!

Another viewpoint is that these things LOOK different even though they
may convey the same information.  As waypoints, if you're looking for
a signpost you may discount what looks like graffiti on a distant rock.

These are signposts.  They are signs.  On posts.

What you are describing is not a signpost.  It's more of a blaze
with text.  If I were insistent upon ramming a square peg into
a round hole, I'd abuse trail_blaze rather than guidepost.
Because THERE IS NO POST.

Re: [Tagging] Is there a good way to indicate "pushing bicycle not allowed here"?

2020-07-23 Thread Alan Mackie
Do we have any tagging for areas where e.g. open alcohol containers are
prohibited,  where firearms are specially prohibited* or disallows
possession of a recording device or camera? A separate 'specific item
banned' tag is starting to sound like it would avoid further muddying the
transport mode tags.

*in jurisdictions that permit them in the first place of course.

In a US Wilderness Area, any form of mechanical transport is
prohibited, so the AlphaDog is out.  Animal transportation is regulated
on a case-by-case (and area-by-area) basis, but in general, horses,
llamas, and donkeys are allowed, while camels and yaks are a "maybe".
Elephants would almost certainly be prohibited because of their
potential to damage the "wilderness character" of the area.
