Yes, it's about a license change by OSM.

I don't think it's outlandish to assume that at least some data donors 
are comfortable with such terms. After all, this is something that we 
expect of individual contributors: The Contributor Terms which every 
person with an OSM account has signed grants us (meaning the OSMF board 
and a 2/3 majority of active contributors) the right to switch to any 
unspecified open license in the future.


Could you expand on what you mean by 'legal text'. Is it a legally 
binding contract?


Answering by way of example: I would expect a similar implementation to 
the standard waiver we ask for before we import CC-BY data:

You have a point that it seems practical to look just at the more narrow 
scenario of another license that requires attribution of OSM. After all, 
a license change is not a high-probability event in the first place, and 
a change to a license that doesn't require some form of attribution 
seems even more unlikely. So it would be useful to be able to record 
something like "as long as attribution is ensured" for an import's 
license change compatibility.

Ok, this is clearly imprecise wording.¹

The context is that we would like to offer data donors a standard legal

that we would expect it to survive a hypothetical license change. And 
yes, this would perhaps look similar to a CC0 waiver, except that it 
could potentially be a bit more limited (in a similar way the CT limits 
the set of licenses under which the OSMF can choose to publish the

So the column would be mostly about whether this legal text or something

has the ability to survive a license change by default could also check

[Talk-de] Kandidatur für den OSMF-Vorstand

2020-12-04 Thread Tobias Knerr
Hallo zusammen,

morgen beginnen die diesjährigen Vorstandswahlen¹ der OSM Foundation,
und wie einige von euch schon wissen, habe mich entschieden, noch einmal
anzutreten.

Ich bin ja jetzt seit zwei Jahren Vorstandsmitglied. Nicht alle Ideen,
die ich bei meiner letzten Wahl hatte, waren im Vorstand mehrheitsfähig,
aber einiges konnte ich doch umsetzen – etwa die Mehrheit der Punkte,
die ich in meinem damaligen Wahlprogramm² aufgeführt hatte.

Nichtsdestotrotz ist das eigentlich eine Daueraufgabe. Manche Probleme
sind wir angegangen, dafür kommen neue Herausforderungen auf uns zu, z.B.:

* Die zunehmende Firmenpräsenz in den Working Groups der OSMF.
* Die Risiken, wenn Arbeit in der Foundation zunehmend durch bezahlte
Kräfte erledigt wird.
* Der wachsende Anteil bezahlten und organisierten Mappings an den
Beiträgen zu OSM, und die Nutzung von Werkzeugen wie RapiD.
* Die immer noch unzureichende Durchsetzung unserer Standards für
Namensnennung, gerade bei prominenten Datennutzern wie Facebook.

Dafür zu sorgen, dass die Interessen der freiwilligen Mapper bei den
Veränderungen in OSM nicht unter die Räder kommen, wird also weiter ein
Schwerpunkt für mich sein. Allerdings will ich mich nicht darauf
beschränken. Mir liegt auch am Herzen, den Innovationsstau bei der
zentralen Infrastruktur von OSM zu lösen: Dass etwa die API seit über
einem Jahrzehnt keine großen Updates mehr erlebt hat, die OSM-Hauptseite
nur einen Bruchteil der Möglichkeiten von OSM zeigt, die Leute von Forum
und Mailingliste in proprietäre soziale Netzwerke abwandern oder dass
wir lange gewünschten Website-Features in den letzten Jahren kaum einen
Schritt näher gekommen sind. Da die OSMF diese Dienste betreibt, sollten
wir auch dafür sorgen, dass sie mit dem Rest des OSM-Universums Schritt
halten.

Die offizielle Sammlung³ der Antworten und Positionen aller Kandidaten
wurde inzwischen veröffentlicht, meine findet ihr hier:
https://wiki.openstreetmap.org/wiki/Foundation/AGM20/Election_to_Board/Answers_and_manifestos/Tobias_Knerr

Dort äußere ich mich sehr viel ausführlicher (auf Englisch, aber es
überlebt eine automatische Übersetzung einigermaßen heil :)). Ich stehe
euch aber auch hier auf der Liste gern Rede und Antwort!

Viele Grüße,
Tobias


PS: Ich möchte euch bei dieser Gelegenheit die zusammen mit den Wahlen
stattfindenden Abstimmungen über eine Ausweitung der Beitragsbefreiung
für aktive Mapper auf die normale Mitgliedschaft sowie die beiden
Vorschläge zum Schutz vor Übernahmeversuchen (Mindestvoraussetzungen für
die Mitgliedschaft, Verbot von durch den Arbeitgeber gesteuerter
Stimmabgabe) ans Herz legen. Die letzten beiden sind zwar noch keine
konkreten Änderungen, sondern nur eine Aufforderung an den Vorstand,
entsprechende Vorschläge zu erarbeiten, aber ein klares Ergebnis würde
dennoch ein wichtiges Signal senden.

When I asked him, Spanholz said he would be happy to see the questions

Which open platform? Up to whoever volunteers. :)

Re: [OSM-talk] reddit AMA with some OSMF Board members. 15:00Z 9 Nov

2020-10-29 Thread Tobias Knerr
I've been considering the downsides of using a proprietary channel when
I was invited to participate. My thinking is:

* The questions and answers are publicly visible. (Yes, Reddit may nag
you sign up or install their app – close that noise.)
* Spanholz, the user who has been most active in organizing this AMA,
has already offered to post questions on behalf of other people. So you
can send in your questions without needing to sign up to reddit.

For something that's not an official event (just something individual
board members participate in), these options seem good enough.

Is it ideal? No, and I would be more than happy to participate in an
event hosted on our open platforms. But it's an initiative that I want
to encourage, as I hope it could get more OSM community members
interested in foundation matters, and the foundation could use more
active participation. It would be even better if community members took
the initiative to run more fun events on our self-hosted platforms –
that would probably do more to make them more lively and active than the
board could ever hope to achieve with its decrees.

(And of course you can ask questions on OSM channels around the year, no
need to wait for an "AMA". I know I don't need to tell that to you in
particular, but I wish the bulk of the community was less shy about
speaking up on OSMF issues.)

Not every communication between a member of the board and one or more

Given that they're using Google Maps, I doubt it.

But I do feel there is some potential for a free collection of
crowdsourced 3D models for use with OSM (beyond what's possible with
Simple 3D Buildings). This is the gap I hoped the 3D Model Repository
(https://3dmr.eu/) would fill, but so far it hasn't taken off.

If someone is interested in helping with that, there's a lot to do.
Creating models, helping with coding (gltf support would be nice, for
example), and there's even data we're permitted to import into 3DMR that
hasn't been uploaded simply due to lack of time for converting/cleaning
up the models.

Yours,
Tobias

It loses the information whether or not a route is signed at a
particular signpost. Because, no, it is not the case that every signpost
will always contain directions for every route running closer than x
meters past it.

You may not personally care about that information, but that's a very

enough to spend time mapping, and I don't think there's anything

4 Jul 2020, 07:35 by m...@teczno.com:

Hi Everyone,

Since Tobias Wrede started this thread in May, the Ops group has
discussed the Help site during our regular meetings. We understand
the importance of the Q site and acknowledge that the software
running it is old and under-maintained.

In addition to the possibility of moving the site to a new
platform like the ones mentioned in this thread, we’ve also
verified that all past Q content can be archived [1] regardless
of future platform and talked about potential underlying causes of
the frontend script problems some users have experienced [2].
Currently, the Ops group has two initial conclusions:

1) We aren’t able to confirm the extent of the Javascript problems
described in this thread because we lack a front-end monitoring
that would provide this information. Our existing monitoring
extensively covers the underlying server, shenron [3], alongside
superficial uptime measurements [4].

2) The Q server is shared by Trac and SVN services which are
being deprecated over the next month [5]. Deprecating Trac and SVN
will allow us to better isolate and observe problems that Q is
experiencing, and perhaps solve them by removing these competing
services on one of OSM’s older pieces of hardware.

Over the next two months, I’ll be watching the thread [2] for
reports of new failures. If these continue past August when SVN
and Trac have been deprecated, we’ll add monitoring to better
understand their cause and determine what work may be needed to
fix or migrate OSM’s Q site.

It would certainly be a improvement for day-to-day work.

The root of the issue, though, is that bounding boxes are a poor basis
to determine whether a changeset is of interest to a mapper watching a
particular region. If a changeset contains a change in France and one in
Poland, then a mapper observing Germany should really just not be
alerted to that changeset in the first place, and it should be possible
for a mapper in Poland to view only the subset of the changes that
affect their own country.

IMO, an ideal changeset represents one logical unit of work. It
shouldn't contain multiple unrelated changes, but at the same time,
related changes should not be split across different changesets. Right
now we're intentionally doing the latter to work around the limitations
in our tools, and I understand and support that, but I hope this view of
"large bbox = bad" doesn't get too firmly entrenched. Let's keep in mind
that it's essentially a workaround for missing software features, that
the proper fix is to improve the software, and that we should drop this
rule once the reasons for it no longer exist.

The =construction + construction= tagging is only really

Other tags are more likely to use to use lifecycle prefixes:

Re: [OSM-talk] Let's talk Attribution

2020-04-30 Thread Tobias Knerr
Hi Alexandre,

it's true that too many projects using OSM do not provide the required
attribution. However, I'm surprised that you got reactions of
"this is fine" for some of the more egregious examples you mention in
your email. While individual mappers will of course hold a wide range of
opinions, that is not the position of the OSM Foundation.

On 27.04.20 19:49, Alexandre Oliveira wrote:

I assume this is the same issue as the one described here:
https://github.com/grischard/osm-lacking-attribution/issues/8

Facebook was contacted about this specific problem 2.5 months ago. They
have acknowledged it as an issue, but have unfortunately failed to
correct it so far. For now, we still have hope that they will just
finally fix it. At some point, we may have to take further steps, but we
haven't really come to an agreement on what those would be.

For OSMF action on issues which are less clear-cut (i.e. attribution is
present, but insufficient), the main roadblock is that we have not yet
approved the attribution guidelines which will make it clearer what
style of attribution we expect. Of course, data users are already
obligated to follow our license today, but hopefully the guidelines will
help to eliminate any ambiguity about whether certain controversial
practices are acceptable. The most recent version of the guidelines
drafted by the LWG is almost there, but has drawn community criticism
about being too generous especially w.r.t. initially hidden attribution.
We are working on them, and once they are approved, we will point to
them when we contact data users about low-quality attribution.

I admit that the OSMF has been frustratingly slow to make progress on
attribution, and I hope we will get better about this.
But there's a lot that can be achieved by the community in a distributed
manner as well. You've already mentioned the #AttributionIsNotOptional
initiative as an example. It's not rare to hear success stories about
mappers simply sending a friendly reminder to some companies, especially
small-scale users who made a honest mistake and forgot about the
attribution. It also helps to report lacking attribution to Guillaume's
previously mentioned issue tracker¹ – the board is keeping an eye on
that and prioritizing issues based on whether the site or app has

[Talk-de] Dienste für virtuelle OSM-Stammtische

2020-04-21 Thread Tobias Knerr
Viele OSM-Stammtische finden derzeit wegen der Corona-Pandemie nicht
statt. Es gibt aber Alternativen! Einige Gruppen haben schon erste
virtuelle Treffen erfolgreich durchgeführt.

Wer noch auf der Suche nach geeigneten Diensten dafür ist, findet hier
ein paar von uns getestete Vorschläge:

* BigBlueButton: Der OSMF-Vorstand benutzt seit April eine gemietete
Instanz der freien Videochat-Software BigBlueButton für
Vorstandstreffen. Diese steht auch der OSM-Community zur Verfügung. Um
sie zu nutzen, muss einer der Teilnehmer des Treffens sich unter
https://osmvideo.cloud68.co/user/signup registrieren. Nach der Anmeldung
findet man dann einen Link zu seinem eigenen "Home Room", den man mit
anderen Nutzern teilen kann.

http://imagico.de/files/bbb1.png

* Jitsi: Die derzeit wohl bekannteste freie Lösung für Videochats. Es
gibt eine ganze Reihe frei nutzbarer Jitsi-Server im Netz, eine Liste
findet sich unter https://pads.ccc.de/ep/pad/view/jitsiliste/latest.  Um
ein Jitsi-Treffen zu starten, wählt man dafür einen eindeutigen Namen
und teilt diesen mit allen Teilnehmern.

http://imagico.de/files/jitsi1.png

* Mumble: Wer auf das Video-Bild verzichten kann oder möchte findet mit
Mumble eine deutlich schmalbandigere Lösung, die aber im Gegensatz zu
den übrigen Möglichkeiten die Installation einer eigenen Software
erfordert.  Wer schon mal bei einem FOSSGIS- oder OSMF-Vorstandstreffen
zugehört hat, kennt dies bereits.  Eine Anleitung findet sich unter
http://podcast.openstreetmap.de/mitmachen/.  Der FOSSGIS-Mumble-Server
kann von allen in der OSM-Community verwendet werden, daneben gibt es
als Ausweich-Möglichkeit auch noch einen Mumble-Server von HOT:
https://wiki.osm.org/Mumble

Egal für welche technische Lösung ihr euch entscheidet - am Anfang mag
dies erst einmal ungewohnt erscheinen.  Aber ausprobieren lohnt sich!
Viele, die jetzt in Zeiten der Corona-Pandemie zum ersten Mal virtuelle
Treffen ausprobiert haben sind positiv überrascht, wie kommunikativ so
was sein kann.  Also: keine Scheu beim ausprobieren und teilt Eure
Erfahrungen in der OSM-Community.

(Danke an Christoph für die Hilfe beim Testen und Texten!)

Agreed, the text in parentheses is problematic. From a moral
perspective, explicitly crediting the foundation would very much feel
like an unjust appropriation of the mappers' work, regardless of the
legal technicality that the OSMF is publishing the database.

+1. To me, the foundation is not OpenStreetMap. It's an entity that
exists to *support* OpenStreetMap. (It's good that the OSMF makes this
mental distinction visible by using separate domain, osmfoundation.org.)
When I think of OpenStreetMap, I think of the many people who help build
our map, not a formal incorporated entity. I hope that other mappers
also see themselves as part of OpenStreetMap. So as I said before, I
like the core of the suggestion – but it could have been presented
better by leaving the foundation bit out of it.

Re: [OSM-talk] OSM is not the place for dissemination of authoritative data sets

2020-03-19 Thread Tobias Knerr
On 19.03.20 17:54, Jóhannes Birgir Jensson wrote:
> So - why are authoritative data sets an unwelcome addition?

At its core, OSM is a platform for collaboratively editing geodata. So
the following would be strong reasons not to import a dataset:

- other mappers should not edit it (because the dataset is the official
source and changing it would just make it wrong)
- other mappers cannot meaningfully edit it (because we cannot see the
object in the real world and don't have access to useful sources).

The way you describe it, collaborative editing doesn't seem to be a net
benefit to your scenario, and in fact makes it harder to sync updates
with the authoritative source.

So as a thought experiment: Why not just convert your dataset to the OSM
format to make it compatible with the OSM ecosystem, but skip the import
into the main OSM database?

In practice, I guess part of the answer for that is discoverability: Who
wants to hunt down datasets scattered across various servers and
portals? So it's tempting to put it all into a single big database. And
I guess that's ok as long as it doesn't get in the way of the main
purpose of that database too much – which is collaborative editing, not
data distribution. But surely, with a decent implementation of
compatible data layers tracked in some central repository, authoritative
data could be used *with* OSM without being *in* OSM.

among the open source options, at least the Blender plugin blender-osm²
and the OSM2World renderer have terrain support.

As maintainer of the latter, I feel I should point out the current
limitations, though: While OSM2World has support for terrain based on
SRTM, that feature is still very experimental. In particular, there is
no level of detail mechanism for terrain (which makes it not scale well
to wide open terrain in the countryside) and the workflow in the desktop
software is inconvenient (need to download SRTM data manually and update
a config file with the path pointing to the dataset).

Due to these quality and performance issues, the first version of our
still-not-finished WebGL client¹ will most likely not include 3D
terrain. But the goal is to eventually get there, so if you see
potential synergies, please reach out!

I probably wouldn't add the "Country" template. It promises more than
the current page can keep. The page is quite stale at this point, so a
visitor isn't going to find "national events, ongoing projects" or
things like that, unfortunately.

Re: [OSM-talk] Attribution guideline status update

2019-08-09 Thread Tobias Knerr
Thank you for your work! I believe that clearly documenting our
expectations is a very important step towards solving the current
problems surrounding attribution. It will help well-intentioned data
users to avoid accidentally messing up OSM attribution, and it leaves
fewer excuses for the less well-intentioned ones – making it easier for
us to put pressure on them to improve their practices.

I do have a couple of questions/comments about the current draft:

* Can you confirm that the current attribution practices on Wikipedia
and many similar projects would be covered by the "small images" case?

* I believe video games/simulations should be given similar treatment as
fictional movie productions by permitting attribution in the credits as
an alternative to the current options. Not allowing this seems to
contradict the larger "in a location where customarily attribution would
be expected" principle, as rolling credits are customary for many gaming
genres. (I'm mostly thinking of traditional PC or console games here,
not so much of mobile apps.)

* What's the guidance on scenarios where software does not ship with OSM
data, and does not display online maps, but e.g. allows downloading map
data for offline use? Would it be acceptable to make the license
information part of the download process, or is it still required that
attribution is visible on-screen during use?

there were two surveys run by the OSMF in the past months. One was the

Unfortunately, we cannot share the raw dataset as we failed to ask the

if you have specific questions about the results, we'll try to answer if
possible!

The most commonly mentioned concerns were discussed immediately at the
boards face-to-face meeting in Brussels, and board members are currently
tasked to work on several of them. There were also some ideas which we
felt were not part of the board's responsibilities, so we decided to
forward these to the appropriate parties.

A second, more recent survey was directed to working groups. This effort
is still ongoing – not all groups have responded so far, and I believe
we haven't evaluated the responses in detail yet.

In my opinion, the practices that you've turned into subheadings of the
verifiability section are not merely special cases of verifiability.

For example, temporary features are perfectly verifiable (until they
cease to exist, of course). The reasons why it's not usually considered
good practice to map them include the unsustainable maintenance effort
and the impact on offline use of our data.

So I feel these items are really their own separate practices, not part
of verifiability. If you want to avoid having too many top-level

The way it works is that every tag has a "data item". This is the one
for natural=isthmus, for example:

https://wiki.openstreetmap.org/wiki/Item:Q19327

Of course, you're not expected to find this numeric URL yourself. You
can get there from the wiki page for that tag by clicking on a "pencil"
icon next to the description in the infobox, or by using an
"OpenStreetMap Wiki data item" link that appears in the left-hand menu
on every page that has a data item associated with it.

The idea behind data items is actually quite similar to how templates on
the wiki work: There is a number of possible properties that you can
fill in with information. The properties which are currently available
are mostly identical to the ones used by the templates: Whether the tag
can be used on nodes/ways/..., links to related/required/implied tags,
an image, and descriptions in various languages.

If some information is omitted from a wiki page, the infobox will pull
it in from the tag's data item. Otherwise, the information written
directly on the page will take precedence.

A potential benefit of data items is that language-independent
information does not need to be manually copied to each translation. And
while software like Taginfo has been able to extract information from
the wiki for a long time, the hope is that this kind of extraction will
eventually become easier thanks to data items.

I do not believe there has been a community decision to stop adding
information directly on wiki pages. So the other wiki contributor's edit
was probably premature.

Of course, though, the current situation with content duplicated between
data items and wiki pages isn't really ideal. But there's probably still
some work left until data items can fully replace the existing systems
(updating data consumers, plus working on usability and documentation).

I'm in full agreement with the overall sentiment, and this paragraph
sums up a lot of my objections to the proposed deletion policy.

However, I believe that a lot of the social conflicts surrounding this
topic are caused by how MediaWiki implements "deleting" things: Only
admins can restore a deleted page or even view its history. In contrast,
everyone can undo a regular deletion in the OSM database (at least in
theory), and the history remains publicly visible.

So after a similar discussion several years ago, we created this
template for archiving proposals:
https://wiki.osm.org/Template:Archived_proposal

It basically amounts to removing a page's _contents_ (but not the page
itself or its history) and replacing it with a link to a previous
version of the same page that still had the original content. There's
also typically some basic information left on the page so that users
arriving from an external link know what they are looking at. This is
what a proposal "archived" in this style looks like:
https://wiki.osm.org/Proposed_features/barriers

It mostly achieves the same goal as deletion, especially reducing the
likelihood of getting in the way of searches (because there's little
content left to be indexed). Actually, it may do so a bit too well –
I've always been a bit concerned that it makes it hard to find old
proposals even when you're explicitly looking for them – but because
there are other approaches for finding proposals in particular (the RFC
mails, and the infobox links on key/tag pages back to the proposal),
they can still be found reliably.

The main benefit, though, is the ability for others to easily revert
this kind of change. It's easier to be bold in cleaning up the wiki when
you know that that others can quickly undo any edits they dislike.

Das scheint die herrschende Einstellung zu sein, ja. Zitat Bryan Housel
frisch von letzter Woche: "I basically just disregard everything on the
tagging mailing list and the OSM wiki."

https://github.com/openstreetmap/iD/issues/5835#issuecomment-477696136

Das ist natürlich nicht die erste entsprechende Äußerung und der Link
wirft auch sonst kein schönes Licht auf die iD-Entwicklung: Bryan äußert
sich negativ über die Community, vertritt kontroverse Taggingansichten,
die er via iD durchsetzen will, und sperrt beim Aufkommen von Kritik die
Github-Diskussion für Nichtentwickler. Letztlich geht es auch hier
wieder nur um eine Kleinigkeit, aber das Gesamtbild aus diversen solchen
Vorfällen macht auch mir inzwischen Sorgen.

Dass das alles mittelfristig ein Problem fürs Projekt werden kann, ist
aus meiner Sicht ziemlich offensichtlich. Bei der Frage nach Lösungen
würde ich mich im Großen und Ganzen Michael anschließen. Die wesentliche
Hürde für eine (über die Kritik an Einzelentscheidungen und eventuelle
Eskalation via Abstimmungen und DWG hinausgehende) Reaktion ist m.E. das
Fehlen plausibler Alternativen. Wenn sich jemand fände, der eine auf
Community-Konsens zurechtgestutzte Version der Tagging-Vorlagen von iD
pflegt, sähe das schon ganz anders aus.

The same message was also sent to personal mail addresses of OSM

Additionally, it was posted to several other lists on the lists.osm.org

dead "party" list¹.

Overall, this is the 5th time I'm receiving a copy of this questionnaire

Mostly for the reason which Mateusz has mentioned in his response:
Keeping obsolete tagging around for years or decades adds to the burden
of concepts that new community members need to learn to fully understand
our data.

But additionally, I would argue that removing them all at once actually
results in a cleaner history than automatic removal by editors. It seems
to me that performing these edits in one clearly labelled changeset fits
our best practices – grouping related edits into a changeset and using
meaningful changeset comments – much better than mixing them into
completely unrelated changes would.

Ja, solche Relationen werten normalerweise nur 3D-Renderer aus. Die
Informationen, die auch andere Anwendungen brauchen, sind daher am
Umriss besser aufgehoben.

Als "belastbare Doku" würde ich "Simple 3D Buildings" heranziehen, den
Taggingstandard fürs 3D-Mapping: "Building attributes (e.g., address,
name, overall height, operator, etc.) must be tagged on the building
outline."¹

In diesem Beispiel ist die Relation übrigens auch für 3D eigentlich
nicht notwendig: Sämtliche Gebäudeteile liegen innerhalb des Umrisses
und es gibt keine Überlappungen/Mehrdeutigkeiten mit anderen Gebäuden.

As you seem to remember what was going on at the time, maybe this is an
opportunity to get an answer to a question that I've raised back in
2012, but (iirc) never got a response to: Who made the decision to add
this requirement to the copyright page?

https://lists.osm.org/pipermail/legal-talk/2012-October/007306.html

I don't perceive off-map attribution as a recent trend: This style of
OSM attribution was reasonably popular even back then, especially in
mobile apps. And I don't remember any widespread calls for restrictions
on the practice. In fact, the only mailing list discussion I recall is
the one linked above, which had barely any participants: Three people
questioning the then-recent change¹, and no one showing up to explain or
defend it.

So while I would agree that it's important for data users to respect the
community's policies, it's not yet clear to me that these highly
specific requirements on attribution placement did originate with the
community in the first place.

> a) we are happy for attribution to be behind a credits screen and we

This is my personal preference, but I would still require equal
prominence with other brands. Showing "Mapbox"² on-map, but moving OSM
elsewhere, does not feel fair.

Especially in situations where a data user does make other efforts to
put OSM in the spotlight – e.g. by telling the user about OSM during map
downloads or through a long-lived, or interactive, splash screen – I
believe we should not insist on the corner placement.

Tobias

> I mainly wanted to make everyone who is not active on the wiki aware of

For the benefit of people who don't know the background, it's worth
mentioning that these bot edits did not distort the actual meaning of
the wiki pages, but were purely performing a trivial technical
maintenance task.

Here's an example:
https://wiki.osm.org/w/index.php?title=Tag:waterway%3Driverbank=1805725=1650789==2015

To explain what's going on: The infoboxes on tag documentation pages are
available in different languages. In the past, users editing the wiki
had to manually set the desired language for the infobox with parameters
such as "lang=en". That's no longer necessary because the infobox now
automatically recognizes that it's part of an English page, and that it
should probably display "Description" rather than "Descripción" or
"Beschreibung".

So as there is no longer a point in having "lang=en" parameters, they
were recently removed by a bot. These edits are marked as bot edits,
which not only makes it transparent that the edit was performed by a
bot, but also solves the practical issue of watchlist spam (because such
edits can be easily filtered out from the watchlist).

Note that this wasn't some AI making decisions on its own, either, but
simply a human editor deciding to remove a particular line of text from
more than one wiki page at the same time. The bot API is just a tool
that makes this process less tedious.

Moin,

es tut mir aufrichtig leid, zwei positive Antworten als solche mit  
meinem Dank versehen als Beispiele zum Denkanstoß für einen  
Mitstreiter "mißbraucht" zu haben, dessen Antworten einen sachlichen  
Themenbezug vermissen lassen. Wird definitiv nicht wieder vorkommen!


Zu den Themen selbst, beschleicht mich mittlerweile die Vermutung,  
dass auf breiter Linie fast nur geblockt und gemauert wird, als das  
sich sinnvolle Ideen umsetzen lassen würden. Jeder will pünktlich  
seine Pakete, jeder will volle Regale, jeder möchte möglichst  
ungehindete Fahrt auf "seinen" Wegen, aber die Bereitschaft od.  
Erkenntnis bereits vorhandene Informationen einfach nur sichtbar zu  
machen, tendiert gegen Null. Statt dessen wird auf Spezialkarten  
verwiesen, deren Existenz damit überflüssig gemacht wird und die  
tatsächlich nur schwer gefunden werden können. (ich habe die  
Suchmaschinen VOR meiner Anfrage mehrfach gequält, denn mir war die  
pure Existenz dieser Spezialkarten durchaus bekannt).


Sowohl die Aussage, dass keine Verkehrszeichen gemappt werden, als  
auch die, das der Kartenstil "überfrachtet" wird, sind schlicht und  
ergreifend falsch. Ampeln SIND Verkehrszeichen und das Tor im  
Gartenzaun oder die Feuerstelle im Wald haben die gleiche  
Berechtigung wie ein ganz reales Nadelöhr aufgrund von  
Beschränkungen in den Abmessungen und/oder Gewichten, zumal es  
hierzu einen wesentlich größeren Interessenten- und Betroffenenkreis  
gibt, nämlich jedesmal dann, wenn ein Fahrzeug vor solch einer  
Höhenbeschränkung wenden darf und alle anderen deshalb im Stau stehen.

[Talk-de] Kandidatur für den OSMF-Vorstand

2018-11-06 Thread Tobias Knerr
Hallo zusammen,

ich habe dieses Wochenende erfahren, dass Peda (Peter Barth) aus dem
Vorstand der OSMF ausscheiden und nicht erneut kandidieren wird. Peda
hat aus meiner Sicht einiges erreicht, was das reibungslose
Funktionieren unseres Projekts, die Transparenz der Arbeit des Boards
(z.B. durch öffentliche Vorstandssitzungen und die Veröffentlichung von
Abstimmungsergebnissen), das Bekenntnis zu freier Software und offenen
Kommunikationsplattformen und nicht zuletzt die Vertretung der
Interessen von ehrenamtlichen Mappern angeht. Ich glaube, dass Peda auch
deshalb wertvoll für die Community war, weil er derzeit als einziges
Boardmitglied keiner Firma oder humanitären Organisation mit
geschäftlichen Interessen an OSM angehört. Für seine gute Arbeit möchte
ich ihm hiermit herzlich danken!

Da es mir wichtig ist, dass diese gute Arbeit auch in den kommenden
Jahren fortgeführt werden kann, werde ich mich für den Vorstand der OSMF
zur Wahl stellen. Ich bin in der OSMF seit 2009 Mitglied und auch in
einigen OSMF-Arbeitsgruppen gelegentlich aktiv. Vor allem aber bin ich
seit langem als Mapper und inzwischen auch als Hobby-Entwickler in der
OSM-Community zu Gange. Auch aus dem Forum oder Wiki dürften mich einige
von euch schon kennen.

Ausführlichere Infos liefere ich später noch nach, auch über die
offiziellen Kanäle: Es soll auch dieses Mal wieder Wahlprogramme sowie
die Möglichkeit zum Einreichen von Fragen an die Kandidaten geben. Da
die Vorstandswahl im deutschen Forum dank der fleißigen
Mitgliederwerbung von Nakaner aber bereits Gesprächsthema ist, wollte
ich den sprichwörtlichen Hut schon einmal in den Ring werfen. Und
natürlich dürft ihr mich auch jetzt schon mit Vorschlägen, Kritik und
Fragen löchern!

Viele Grüße,
Tobias

Das ist unstrittig. Strittig ist, was die "Strecke" ist. Bei einer

Again, the max weight is not the same as the max allowable weight. Using 
maxweight in this context is wrong.

See the Key:hgv wiki page where I added an explanation and examples.

Re: [Talk-GB] Access restrictions for lorries above a certain GVM

2018-09-26 Thread Tobias Zwick
Thank you for the answers given. Perhaps there are some
misunderstandings, so I want to clarify two points:

1.
A HGV is defined as a vehicle with a max allowable mass of above 3.5t,
even in the UK. Tagging "hgv=no" when seeing this sign is plain
incorrect, except if we specifically redefine only for OSM what
constitutes a HGV contrary to what can be found in the actual
legislation. I don't think it is wise to do that.

2.
How HGV are defined (>3.5t) and what can be seen on signs like these
(7.5t) is NOT THE WEIGHT but the maximum allowed weight. This is very
important.
The maximum allowed weight, also known as the gross vehicle mass or GVM
or GVWR is the maximum permitted weight of the vehicle at full load, as
specified by the manufacturer. (See
https://en.wikipedia.org/wiki/Gross_vehicle_weight_rating)

Just to be clear, an example. Let's say there is a lorry with the
following properties on the road:
- Without any load it weighs 2 tons -> this is the unladen/empty weight
- It carries 4 tons of gravel -> this is the tara/load
- It currently weighs 6.5 tons
  -> this is the current/actual weight. Used for maxweight=*
- It could load up to 7 tons -> this is the maximum capacity
- It is permitted to weigh in total up to 9 tons
  -> this is the maximum permitted/allowed weight/mass, aka gross
 vehicle mass, aka GVM
- in other words, GVM = unladen weight + maximum capacity

Thus, using maxweight=7.5 is incorrect already because the maxweight tag
is about the maximum CURRENT weight. A HGV whose permitted maximum
weight is above 7.5 tons but which currently weighs below 7.5 tons is
not allowed on roads signed with the linked sign.

So, these are the points I wanted to clarify. Also, turns out that
someone else already noticed the exact problem and created a proposal
for this, which seems kind of abondoned, as usual:
https://wiki.openstreetmap.org/wiki/Proposed_features/gross_weight

How can we get this proposal started again? Because, the only correct
way to tag the sign initially posted here would be with

maxweightrating:hgv=7.5

(if the proposal is unchanged)

Greetings
Tobias

The content stored in Wikibase is editable by wiki users using a regular
wiki account, same as with other wiki pages.

Ultimately, this is simply a different implementation of the infoboxes
that already exist on the wiki's key and tag pages. An implementation
that will be easier to maintain and easier to parse for projects like
Taginfo (which already parses today's infoboxes, but has to jump through
a lot of hoops to do so). But it isn't any more restrictive than filling
in the parameters of today's infobox.

Indeed, the search field is pretty much broken at the moment.

However, this has been brought up on the wiki talk page, and Yuri said

As one of the more active editors of the wiki, I'm very hopeful for this
project. The current "solution" for this kind of data is to manually
copy templates across several pages. This is a massive pain point and
leads to pages unintentionally getting out of sync all the time.

Of course, it's still too early to say whether the idea will work out.
But I'm willing to help it succeed.

Im Allgemeinen tendiert der Konsens in der Community dahin, Relationen
nur dort zu verwenden, wo sie notwendig sind.

Aus diesem Grund ist auch in Simple Indoor Tagging anders als bei dem
von dir verlinkten älteren Indoor-Proposal vorgesehen, dass der
Gebäudeumriss + level-Tags an den enthaltenen Elementen für die
Zuordnung zum Gebäude ausreichen soll.

Einen sehr ähnlich gelagerten Fall gibt es übrigens bei
3D-Gebäudemapping: Auch dort ist die Nutzung von Relationen zur
Zuordnung von Gebäudeteilen zum Gesamtgebäude in den allermeisten Fällen
optional¹ und unüblich – die weit überwiegende Mehrheit der 3D-Gebäude
verzichtet darauf.

Wenn du dennoch eine Relation verwenden willst, dann ist die
building-Relation die gängigste Wahl. Ich würde aber wie gesagt eher
davon abraten. Auch eine geringere Fehleranfälligkeit von Relationen
halte ich in der Praxis nämlich nicht für gegeben: Es ist einfach zu
schnell passiert, dass ein Mapper z.B. ein neues Objekt ergänzt, es aber
nicht zur Relation hinzufügt.

One trait we're looking for in GSoC students is familiarity with the OSM
community. So at this point, it might not be a bad idea to do some
mapping in your local area, to explore the ecosystem of OSM-based
software, and so on.

In 2019 (assuming OSM will be selected as a mentoring organization), we
will publish a list of project ideas, much as we did this year. At that
point, you will be able to get in contact with the mentor(s) of the
specific ideas you are interested in, who may be able to suggest some
preparations more closely related to the development project in question.

Of course, you can also get in contact with developers directly if you
already know that you're interested in a particular open source project
under the OSM umbrella.

For routing purposes, barriers are usually connected to the highway=*
way somehow. When barriers are mapped as nodes, this is achieved by
tagging one of the way's nodes with the barrier tags.

How would we do this for barrier=block mapped as areas?

Note that the block(s) will not always be exactly on the centerline of
the highway, so we may not be able to even share a node between the area
outline and the highway way if we want to accurately represent the area
covered by the block. Due to this, I see no easy solution to map blocks
as areas while still making them topologically part of the routing network.

These tagging schemes are for 2 different real-world features:
* roads/paths (i.e. linear features with a direction)
* plazas/squares (i.e. open areas where people will walk across in all
directions)

Linear roads/paths are mapped as highway=* ways, optionally with an
additional area:highway=* polygon.

Plazas/squares are mapped as highway=* + area=yes polygons.

So the area:highway key is never an alternative to highway polygons with
area=yes! In any given situation, only one or the other will be correct.

Ich stimme zu, dass es einen Unterschied macht. Schöne Tagging-Lösungen

derzeit nur, das Ergebnis der Überschlagsrechnung als height-Tag am

Im Prinzip könnte ein Renderer natürlich abhängig von

Das ist ein häufiger genanntes Problem, für das es meines Wissens
ebenfalls noch keine Lösung gibt – Interesse hätte ich und würde das
z.B. auch in OSM2World gerne einbauen.

Nicht ganzzahlige building:levels-Werte sind leider nicht gut
auszuwerten, weil man nicht weiß, _wo_ am Gebäude das halbe Stockwerk
ist. Das ist für die reine Höhenschätzung kein Problem, wohl aber wenn
man z.B. Fensterreihen einzeichnen oder Indoor-Mapping ins Gebäudemodell
einpassen will.

Theoretisch gäbe es sogar eine Lösung unter Verwendung von bestehenden
Tags, nämlich Simple Indoor Tagging: Man kann eine Fläche fürs
Erdgeschoss einzeichnen (indoor=level + level=0) und mit min_height=0.5
taggen. Aber eigentlich sollte ein so häufiger Fall einfacher abzubilden
sein, vor allem ohne den Pflegeaufwand von zusätzlicher Geometrie...

Re: [Talk-it] Should StreetComplete stop adding addresses in Italy?

2018-07-13 Thread Tobias Zwick
Hmm, I was hoping for a more definite answer than what I got from this
thread so far. I will give you some more input.

Regarding the ideas expressed so far:
Adding a node within the building with the housenumber is not possible,
because StreetComplete can only change the tags of an element, neither
add, delete or change the geometry of elements - but it doesn't matter
really if there is a node with an address within the building with a
fixme-tag or the address is just on the building: It requires cleanup to
conform to the Italian address guidelines in either case.
Also, a detection whether a housenumber is "nearby" specifically for
Italy is also something I will not do, because such a detection would be
too fuzzy to be reliable. But it needs to be reliable.
Finally, regarding the idea to let StreetComplete ask for the addresses
on gates and entrances instead of buildings in Italy, that would create
lots of false-positives (not every gate or entrance has an address). I
think if the building is already mapped in such a detail that the
entrances are also mapped, someone must have been there to survey it and
then he will have also specified the housenumber (if that entrance has one).

To summarize, I see no chance how StreetComplete, or for that matter,
any automatic algorithm, would be able to automatically determine where
and which housenumbers are missing on the map, when housenumbers are
mapped on plot boundaries instead of always on, in or at the entrances
of buildings.

---

Certainly, StreetComplete can be very useful in filling the white spots
regarding addresses in Italy, and it is true that as OSM is a
collaborative project, other mappers can later separate the address from
the building outline and put it on the entrance(s) to make it conform to
the guidelines. Also, most (inner-)town buildings will have their
address on the entrances and many buildings just have one entrance, so
there is no problem.
However, you also have to consider that StreetComplete will definitely
be a disruption in areas where the address is commonly (mapped) at the
gates leading to the properties (=outside the building outline). In
these areas, the buildings may be spammed with either duplicate
housenumbers or noaddress=yes tags. Worse still, if you clean up the
duplicated nodes after a StreetComplete user added them, they may appear
again later, when another user adds them again, and so on.

So, you have to weigh the these up against each other and decide.

Anyway, thank you for the praise :-)

[Talk-it] Should StreetComplete stop adding addresses in Italy?

2018-07-12 Thread Tobias Zwick
Hey there

Since early 2017 till now, users of my app StreetComplete have been
adding house numbers to buildings.
Should I disable this functionality for Italy?

For buildings of certain types, such as "apartments" or "house"s etc.
(but not "yes"), which do neither have an address tagged, nor have any
node on or in their outline with an address tagged, nor are in any area
that has an address tagged, the app shows a pin on the map, like this:

https://raw.githubusercontent.com/westnordost/StreetComplete/master/fastlane/metadata/android/en/images/phoneScreenshots/screenshot8.png

This pin is shown to every user of the app, until it is solved. To solve
it, the user taps on the pin and can input the housenumber for the
building in the form that pops up then. The user can also answer that
the building has no housenumber, in which case the app tags noaddress=yes.

They will, but at a lower rate. Mappers often look at existing tagging
to find out how things should be tagged. This is further reinforced by
tools such as JOSM's autocompletion. Thus, I believe the current dataset
should always be as.clean as possible in order to set a good example.

Mostly eliminating the FIXME spelling now (instead of waiting for it to
disappear naturally over the next decade) will also allow us to simplify
the wiki documentation a little bit, get rid of special cases in tools
and so on. That may only be a small benefit, but it's the sum of all
these small exceptions, duplications and special cases that make
learning the OSM data model unnecessarily hard for mappers and data
consumers alike.

In my opinion, software should not _need_ to deal with both. Working

razed:man_made=watermill -> Eine Wassermühle, die "razed" ist.

demolished=yes -> auch kein dokumentiertes Tag, oder? Sollte wie oben

Aus den drei Tags sollte meiner Meinung nach genau eins werden:
razed:man_made=watermill (oder demolished:man_made=watermill, der 
Unterschied ist nicht wirklich scharf und nachvollziehbar)
Mann könnte sogar auch noch ein razed:building=yes ergänzen, wenn es 
sich hier nicht um eine offene Mühle gehandelt hat.


Wenn man den Standpunkt vertritt, ein nicht mehr vorhandenes und

Abrissdatum ist drin, es ist explizit darauf hingewiesen, dass das 
Gebäude abgerissen wurde.


Im Gegensatz zu so manchem erfassten "abgerissenen" Gebäude ist in 
gewissem Maß sogar das Gebot "nur mappen was vor Ort nachvollzogen 
werden kann" gewahrt. Eine Tafel vom Spessartbund (hier verläuft ein 
Kulturweg, der auch mehrfach auf die Mühlen hinweist) verweist auf den 
Standort. Kann also für jeden nachvollzogen werden auch ohne 
"Ortskundige" zu fragen.


Hintergrund für das Anlegen des Knotens war, dass ich gerne einen 
Eintrag dafür hier haben wollte:


http://gk.historic.place/historische_objekte/translate/en/index-en.html?zoom=17=49.96999=9.63967=HaHbHcSaHe 



Steht da auch korrekt als "former watermill location".

Weiterhin nutze ich den Knoten auf der Karte des Heimat- und 
Geschichtsvereins um Infos zum (ehemaligen) Gebäude auf die Karte zu 
packen:


http://karte.hgv-steinfeld.de/

Wie ist die Meinung hier dazu. Wenn es komplett falsch ist, sowas zu 
mappen, dann kann ich das mit meiner Karte auch anders lösen.


Ich selber tendiere aktuell dazu den Fehler mit einem Hinweis auf die 
Tafel, die auf den Standort des ursprünglichen Gebäudes hinweist, zu 
schließen.

I'm in favour of proceeding with the proposed mechanical edit. The tag

I'm not familiar enough with their communities to give a recommendation.

Hi Tim,

I'm going to split this reply into two parts: About the content, and
about the software itself.


As for the content, a lot depends on if you can publish the images under
the terms of an open license.¹ That's a legal question, but probably
also a bit of a social one (i.e. would this be in line with what the
creators expected when they shared their images on your app, or would
they be unpleasantly surprised/unhappy about this).

Assuming the answer is that yes, you can publish them, the next question
is what to do with the images. OSM does not currently have an image
hosting platform, so if we're only talking about contributing the
images, they would need to be donated to a separate platform.

The obvious recipient for such an image donation would be Wikimedia
Commons, as they're the most popular repository for open-licensed media.
Images on Commons can be linked with OpenStreetMap POIs² and are used as
such by some OSM-based maps. Of course, they're also used by Wikipedia
and its sister projects – notably Wikitravel, which is a crowdsourced
travel guide (although much closer to the traditional book format than
your project).

A caveat is that such a donation would likely require some manual effort
to filter out lower-quality pictures or duplicates, and to add
meaningful descriptions. Still, assuming the legalities work out, it
seems feasible to donate the images and would be a generous contribution
to the open content ecosystem.


Ok, so let's talk about the app and backend a bit. I'm not sure how
familiar you are with OSM's organizational model, but as a rule we're
very decentralized – even core components of OSM are being developed as
mostly independent Open Source projects. For you, this means that even
if there's community interest, any re-use of your project would probably
still start out with _you_ spearheading its development, re-imagining it
as something you believe fits a need of the OSM community, and trying to
gain mindshare in the OSM contributor and developer community. Of
course, this may be at odds with your goal to focus on other projects.

If this does not discourage you, though, let's consider what needs the
software could serve. I don't have any amazing ideas to offer, but I
could see two basic roles in the OSM ecosystem an image platform might
potentially be able to fill. Broadly speaking:
* Images could be used internally by OSM contributors as a data source
for mapping in addition to sources as aerial imagery and GPS tracks.
* Images could be displayed by user-facing sites and apps alongside OSM
data. (I believe this is what you were getting at with your Google Maps
comparison.)

The former use case is already partially covered by
Mapillary/OpenStreetCam, so the question is if there's enough of a niche
left for another app.

The latter seems more ambitious. As I mentioned before, mappers are
currently using tags like image=* with links to external platforms to
add images to OSM POI. Those links can technically point anywhere,
although Wikimedia Commons currently appears to be the most popular
platform to host the images. Inviting users (including non-mappers) to
easily contribute images to a dedicated, OSM-affiliated platform might
be a worthwhile cause. Not sure how well this fits your platform's
existing social features, though.

Hey Phil

The quest pin is still in your application's cache. The app downloaded
the quest more than 8 months ago.
In any case, no need to worry. In case you solve a quest that turns out
to be outdated (=there is a conflict with actual data), it will discard
that answer and invalidate the cache of the area. You can manually
invalidate the cache in the settings.

Also,

6. Did you come up with the term "restricted" or is the term actually
used within the same context as single / dual carriageway in the UK
legislation? Because, that term is usually used for quite another thing
in OSM context (restricted access roads). But, as long as the nsl_*
taggings in themselves are consistent (in that they use the terms from
the UK legislation), that's fine, I guess. Otherwise, we should perhaps
look for a more fitting name before I cast it into code.

So then, in case the user answers in the app that there is no sign, the
app could ask the user whether the street is lit. Only if it is not lit,
it tags the street as nsl_single/nsl_dual. Would that solution be correct?

Re: [Talk-GB] Implicit speed limits: What to tag in built-up areas?

2018-05-01 Thread Tobias Zwick
This tag is not invented, it exists in other countries where slow zones
exist as well.
Also, there *is* something special about it, otherwise the sign would
not be different from a normal maxspeed sign, wouldn't it? (And the
wikipedia article wouldn't exist)
The special thing about it, is that the posted maxspeed is valid for the
whole zone, in other words, until the maxspeed zone is explicitly posted
to be over. No repeater signs on crossroads and not even for adjacent
streets.

Yes, there is a certain similarity with the "normal" 30 mph limit in the
UK, that is why I mentioned "maxspeed:type=GB:zone30" in my original
post. Remember that OSM is a worldwide project, as long as something is
not the same in the whole world, it is not "normal".

Re: [Talk-GB] Implicit speed limits: What to tag in built-up areas?

2018-05-01 Thread Tobias Zwick
Okay, I have the impression that the tenor of the answers I got so far
is that a "maxspeed:type=GB:something" tagging would not be necessary
because in practice in the UK, any 30mph limit on lit streets will be
posted explicitly. Thus, the maxspeed should be specified explicitly
(along with "maxspeed:type=sign").

To those who find I summed up their opinion on that matter correctly, I
would like to confront you with an actual problem I encountered with the
surveyor-app StreetComplete of which I am the author of. I linked the
ticket to this issue in my original post.

I am quite sure that this problem can lead to wrong tagging,
specifically that normal urban roads, even residential ones, are tagged
with "maxspeed:type=nsl_single" when they should not.

So I very much want to solve this problem as soon as possible and I am
hoping you can help to find a solution to it and/or understand my point
of view that *some* "maxspeed:type" or similar tagging might be necessary.

I will now explain how this mistagging might come about in the dialogue
of the user with the app:

The app shows the street section which it is about highlighted and asks:
*"What is the speed limit sign for this street?"*
The user can then either fill in an explicit speed limit or answer
"There is no sign".

So, in case the user does not see any sign, as he would on a typical
British urban street, he answers: *"There is no sign"*

The app asks: *"Are you sure no limit is posted? Did you check at the
ends of the street? If there are no signs along the whole street which
apply for the highlighted section, default speed limits apply."*
...and in case of a road tagged as residential, it shows a slow-zone
sign and adds:
*"If there is a sign like this at the main street intersection, you
won't find individual signs within the zone because the speed limit
posted there applies to the whole zone."*

When the user answers *"Yes, no sign"*,
the app just asks (for GB): *"Are the carriageways of this road here
physically separated (i.e. through a barrier)? The default speed limit
depends on whether this is the case or not."*
The app then tags "maxspeed:type=nsl_single" or "maxspeed:type=nsl_dual"
based on the user's answer.

So, if I understand correctly, this "default 30mph limit" within lit
sections of British roads is always signed, yes, but otherwise behave
like 20mph zones in that there are no repeater signs at intersections
and *not even* in roads that branch of this main road and roads that
branch of the branched off roads (right?).
This would mean, that in Britain, it is not enough to tell the user to
look for a sign at the start of the road, but to, well, what exactly?
This is where I need your help. How should the dialog be changed (in GB)
to not create any misunderstandings here?

[Talk-GB] Implicit speed limits: What to tag in built-up areas?

2018-04-30 Thread Tobias Zwick
Hi there

On tagging implicit speed limits in the United Kingdom, the wiki lists
the following values [1] for "maxspeed:type":

GB:nsl_single (=60 mph), GB:nsl_dual (=70 mph) and GB:motorway (=70 mph)

I understand that the current legislation defines a road with
road-lighting as a built-up area in which a lower implicit speed limit
of 30 mph applies. There is no mention of it in the wiki, no GB:urban,
GB:lit, GB:zone30 or anything like that, so something should be defined
and documented by (you,) the British OSM community.

My question:
How to tag roads in which such an implicit speed limit for built-up
areas applies?

The question is motivated by an issue report for StreetComplete [2]

Cheers
Tobias

Re: [OSM-talk] [Diversity-talk] How do you mapping gender neutral toilets? What should the unisex tag mean?

This may be a stupid question, but where are you all getting this
definition from?

I assumed the key already had the meaning that Rory is suggesting here.
And at least on the Key:unisex and Tag:amenity=toilet wiki pages, I see
nothing to contradict that.

The former page mentions that the tag implies male=yes and female=yes,
but "implies" should not be confused with "is equivalent to".

That's not the case, and it's a bit frustrating to read this just after
I wrote a mail explaining this point. To reiterate:

* With separate ways, we don't know which road section a sidewalk
belongs to.
* This knowledge is necessary for many applications.

For such a fundamental property, "research scientists believe they can
use the spatial proximity" is not good enough imo. It has to be
practical to obtain this relationship from OSM data.

I have to say I'm not a fan of this practice, at least for
straightforward cases.

Yes, there are parts of the world where explicit language information is
necessary. But in many others, there is an obvious default, and it feels
wrong to require mappers to manually repeat this on millions of
individual elements. Don't add extra tags to German names in Germany,
for example – tag the exceptions from the rule instead.

As a less important secondary point, I also consider the specific
tagging (duplicating the name with a different key) counter-intuitive
and would prefer a "language of the name" key, with the language given
as the value. The purpose of that tag would be much more
self-documenting than with the recommendation described above.

That being said, displaying labels in the user's language is an exciting
use case, and I hope we can find a solution that allows your project to
succeed. Could you elaborate a bit more on the technical limitations
regarding regional processing?

You mention increasingly small regions as the obstacle. Would that still
allow for the pragmatic compromise of setting country-level defaults,
and using explicit tagging only for smaller-scale language regions?

Why do you think it necessary to map at all if any particular toilet is
segregated or not beyond whether I can go there as a man/woman? What is
the application?

[OSM-talk] Sidewalk symmetry

The percentage of roads tagged with all these details is vanishingly
small, and will likely remain so for at least another decade.

At the level of detail that's realistically achievable in the medium
term, sidewalk tags make a lot of sense: They're easy to use for the
common case (where sometimes not even the existence of sidewalks is
mapped yet), and still allow for micromapping in pockets of unusually
high data quality.

Comparing the mapping styles solely based on ease of mapping would only
make sense if separate ways were able to express the same information
contained in sidewalk tags.

That's not the case, though: With separate sidewalk ways, it's
impossible (in the general case) to figure out which road section that
sidewalk way belongs to.

Not having this basic information available makes separately mapped
sidewalks unusable for entire categories of applications – sometimes
leading to worse outcomes than not having the sidewalk mapped at all.
And while you could fix that issue with relations, this would clearly
not be easier for mappers than using sidewalk tags is.

As for the original question: sidewalk=separate seems like an attempt to
solve the aforementioned issue, but it does not actually achieve this
goal – it only tells you that *some* sidewalk way belongs to this
section of road, but does not help you to find out *which* sidewalk way
that is. As such, it's not a very useful tag, and not a compelling
reason to map asymmetric real-world situations in a symmetric way.

Re: [OSM-talk] "The Future of Free and Open-Source Maps" Slashdot.org , Saturday February 17, 2018

2018-02-18 Thread Tobias Zwick
I also read this article and I found it identifies some areas in which
(the central infrastructure of) OpenStreetMap could improve.

What I do not like about this article is the deeply pessimistic and
resigned tone of it, like clickbait. It reads like "OSM needs to change
from the core up or else it will be doomed!".

Yeah, I don't think so.

And I do not think that this mode of appeal is that productive. It's
good if it sparks discussions about what we can and want to improve, but
I do not think that it is going to inspire anyone to "save" OSM by
innovating things. This is not how it works in FOSS, and not how
innovation works. AI detections of features from pictures/drone videos
for example is not going to happen because someone writes that we
_really_ need this now to keep up, but because someone is enthused about
the concept (and is able to capture others with that).
Also, Serge maybe doesn't know
https://blog.mapillary.com/update/2015/01/27/traffic-signs.html

That there might be a conflict of interest regarding pulling more
technology and services into the core OSM toolset is an interesting
thought that did not cross my mind before and that may very well be
true. Though on the other hand, I consider the fact that OSM runs on a
"shoestring budget" as something that contributes to OSM's
sustainability: I.e. I observe with concern that Wikimedia apparently
requires more and more money every year to survive.
OSM's minimalistic organizational structure is simply a different
concept than WP.

Regarding the "area" type, I agree that it would be a good improvement
to introduce a more fixed notion of areas in OSM data. To introduce
another data type has quite the ramifications on backward compatibility
but there may be other options. Right now, every single piece of
software needs to maintain an area detection based on tags like this:
https://github.com/westnordost/StreetComplete/blob/master/app/src/main/java/de/westnordost/streetcomplete/data/meta/OsmAreas.java#L13-L28
Naturally, it is different, thus inconsistent, for any piece of software
- and needs to be updated for any tagging scheme that comes up.

If I were to name the biggest challenge for us, it would be the
maintainability of the map data, a topic that he never mentions directly.
