Re: [OSM-talk] bot proposal: shop values cleanup (low use values only, 1 used 250 times, three over 100 times, many used less)

Some of the entries on your I disagree with that blanket "Bad Thing". It is much more likely that a general map will show shop=lessrarevalue with a specific icon than shop=veryrarevalue. So if you are using shop=veryrarevalue instead of shop=lessrarevalue you might lose detail in the database, but in practice you will gain detail in actual use. There is probably a sweet spot somewhere in the middle, enough detail to allow to differentiate "important" differences while not adding too much detail overwhelming anybody who wants to use the data.

[...] Very interesting way of framing the issue. First you assert that Facebook is in compliance. Then you talk about "Parts of the community" who want something "beyond the ODbL.". But that's a straw man [1] argument. This argument is not about people wanting something beyond the ODbL. This is about a difference in opinion how the license is to be interpreted. Facebook simply reads the license in a different way than other people. This framing is especially interesting, because as board member you would have to defend the ODbL and have a conflict of interest over any issue where different interpretations of the ODbL between OSM/the community vs. Facebook are involved. But you would not have a conflict of interest over anything "beyond the ODbL". So by framing the issue this way you argued yourself out of your conflict of interest problem in this issue.

Re: [OSM-talk] Updating of land/water polygons (based on natural=coastline) is too slow and unreliable
, the processing stops. When there are no major problems, changes show up within a day which is slower than other changes users do and that's certainly not ideal. Can we improve this process? Sure we can run it more than once a day. But that wouldn't help if it became stuck if there are large changes. It would help if the process could somehow stop the large changes in one area while letting changes in other areas proceed. This would give us some time to fix breakages and to discuss larger changes while not annoying mappers everywhere else. So if somebody can come up with a way of doing this coastline processing in a better way and actually implement it, this would be a great thing in my view. But in the end this is less an issue of the tools, but more of an issue of how the community organizes itself. We have organized editing guidelines and import guidelines for a reason and this case isn't that much different. If you want to do large scale edits that affect a lot of people, you have to discuss them beforehand in a suitable forum. And if you don't do that, we have an established procedure how to handle that: The DWG can step in and revert the change and then we can have that discussion. In the case of the changes in the Chesapeake Bay the mappers seem to have discussed those changes on a Slack channel somewhere probably not realizing how large the change was that they were planning and how many people it would affect, so they chose a forum that wasn't suitable for such a large scale change. We, as a community, could try to better define what kind of changes must be discussed where. But sometimes it is hard to see what consequences some change will have so these things will happen again and that's why it is good to have some safeguards built in like the change check in the coastline processing. I just wish it wasn't me having to deal with that, but some kind of community process.

Exactly. I expect to find information about GPS, about GPS use in OSM, about GPS receivers, about software to work with GPS traces, etc. So I expect to find exactly what I found. Except that I expect to find 10 useful pages, not 5. If the outdated pages were not there, who knows what useful pages I might have found!

Go to wiki.osm.org. Type "GPS" into the search field and look at the suggestions: * GPS (redirect to "GNSS tracelog", looks okay) * GPS device reviews (helpful page and seems to be maintained) * GPSBabel (still useful software, okay) * Gpsmid (software that seems to be maintained, okay) * GpsPrune (not the newest software, but probably okay) * GPS receiver (meaningless page only referring to a few others) * GPS navigation & maps (page says on top: "No longer maintained since 2015") * Gpsdrive (last version from 2012, does it still exist?) * GPS Units for Loan (totally outdated) * JA:GPSトレースの公開性 (I don't speek Japanese so I can't judge this) So from the 10 suggestions, I would say that half are useful, half are not. The wiki is not perfect and will never be. It is okay if you occasionally encounter something outdated or have to do a "single click" further. But single clicks also add up. And it is not so much about the click but about the need to read the contents of the page first. Might be okay for you and me because we have been around long enough to see quickly what's interesting and what isn't. But if you are not familiar with OSM this is daunting.

I just realized that in my other reply to this post I didn't address the question you started with, namely whether tagging proposals are worth keeping. I still think that we should not be overly cautious. We should delete things when in doubt. Otherwise we'll never get the wiki to a manageable level. But there are things worth preserving. And a discussion about tagging might be one of those things. If there is real content, people having different ideas about something explaining their reasons etc., then this is valuable. Tag discussions have the tendency to come back up and often discussions are done again and again because we forget what we talked about the last time or new people don't have the context. So in those cases having some kind of history around could be useful. But there probably are plenty of pages where somebody had some idea that never got any real discussion, maybe about something that found a totally different solution in the mean time. Those pages might not be so important to keep. So as always you have to look at each case. If a page contains content that is still useful for our current world, keep it. But if something is merely interesting for historical reasons then it can be deleted. And yes, there is a gray area there, but humans can be trusted with these decisions and the world will not end if occasionally somebody makes the "wrong" decision. But stalling any progress in the wiki by requiring discussions about any change is certainly not the right way. Look at OSM itself, we allow anybody to delete anything there, too, and it seems to work out mostly.

Re: [OSM-talk] An Archive namespace for the OSM wiki?
One problem with the wiki is that you can't find current stuff because of all the old stuff in there. Deleting helps. Marking them as obsolete doesn't. And moving them to a different namespace is even worse, because it breaks links but doesn't make the page invisible. Anything that makes pages invisible (to users and search engines indexing the wiki) but allows switching on a special "archive mode" where you still see those things would be fine. But as long as a search on the wiki or on the search engine of your choice finds all that old crap, the problem is still there. You still have to click through all the pages you found to see that they are marked as outdated. Preserving history is a worthy goal, but not at the expense of making the current information much harder to find and use. Let archive.org do the history keeping. And if all else fails, it should be possible to revive deleted pages from the mediawiki software.

Hi! this might or might not be related to the hourly change file with the number 56107 being "strange": Osmosis can not read the file 107.osc.gz, it reports a UTF-8 error. But if I gunzip the file, Osmosis can read the file fine. So this points to an error in Osmosis' handling gzip'ed files. Unfortunately Osmosis is no longer maintained. Generally errors like this should probably be reported on https://trac.openstreetmap.org/ or the dev mailing list or #osm-dev IRC channel would be a good place.

It seems you haven't understood the on-the-ground rule 5 years ago and you still haven't. For all intents and purposes there is such an address. Mail will arrive there, people can find the house when looking for it. It doesn't matter what the official record says.

Meines Erachtens stiehlst Du Dich damit nur aus der Verantwortung als Mapper. Du kannst noch so viele Tags irgendwo dranhängen, um mit immer mehr und mehr Detail zu unterscheiden, was etwas ist. Natürlich wohl wissend, dass keine Anwendung diese Details unterscheidet. Und wenn sie das tut, der User nicht unterscheiden kann zwischen den 17 verschiedenen Strichlierungen des Weges und was das für ihn bedeutet. Letzlich bleibt es immer eine subjektive Entscheidung. Und wenn ich eh eine subjektive Entscheidung treffe, dann kann ich auch gleich sagen: Okay, das ist ein Weg oder, okay, das ist kein Weg. Das schöne an OSM ist, dass Menschen sowas entscheiden und nicht Algorithmen. Und Menschen können viele Informationen in diese Entscheidung einfließen lassen. Dazu gehört, wie etwas aussieht, aber auch wie die Umgebung aussieht (wenn es in der Nähe einen offiziellen Weg gibt, dann mappe ich den inoffiziellen vielleicht eher nicht z.B.), wie die beobachtete Nutzung durch Leute vor Ort ist usw. Und ja, da macht man Dinge auch mal falsch. Aber das ist okay, weil andere Mapper nach mir kommen und Dinge korrigieren können.

If the outer ring is a single closed way it is a polygon in its own right and it is perfectly okay that it has its own (polygon) tags. Those tags only apply to this particular way then. If the outer ring is made up of several ways, the tags on them only apply to each way by itself. If those are "line" tags, like highway, or something like a wall, that is fine. But they can't be "polygon" tags like landuse etc. because there is no polygon there. If you need this, you'll need another multipolygon relation combining those ways. This is somewhat different than the older interpretation when we still had old-style multipolygons. But with the new-style multipolygons interpretation, the tags from a collections of objects are *never* aggregated into a larger whole.

When the old-style-mp support was disabled on the main map, this left about 50,000 broken multipolygons, in many cases clearly visible on the map. I didn't see a single complaint about this. So, no, I don't think being a bit more strict with broken MPs will be a problem with the map or would be a reason to delay deployment of a new osm2pgsql version. 10,000 intersection problems in 300 million polygons is a rounding error. Note also that Mapbox has been using libosmium code for a while and they are actively fixing large broken MPs every day to keep the map from breaking in a bad way.

What has changed is that now without the complication of the old-style MPs it is easier to check for correctness of the data in editors and other tools.

I don't understand why the "OpenSomethingMap" issue has you so spooked. I don't think anybody but you thinks something like "OpenWeatherMap" is necessarily related to OpenStreetMap in any way. Why wood you? We all know what a "weather map" is, so this is an "Open" one, which doesn't mean much these days. The biggest problem we had with OpenSeaMap was always not that they were somehow leaching from the great name we have, but that they presented themselves as this great project when all they are is a thin layer on top of OSM. They always downplayed their relationship to OSM instead of using it to build their own reputation by piggybacking on ours. I had to explain to many people that, no, they are just this little offshoot of OSM. Albeit with better marketing. Anyway, this is all moot, because nobody believes that the OSMF would actually sue anybody, let alone a small helpless hobby project, to get hold of their domain or force them to sign some agreement. Especially not when all they are doing is using a name that a judge might or might not see as similar enough to the OpenStreetMap trademark. I am sure you have the best intentions of defending OSM against the big bad conglomerates, but I think the best defense is having a large and open community and eco-system, one where you don't have to ask for permission before you contribute.

My number was not referring to domains alone, but also to other projects, software etc. See below. And, no, the policy is not clear at all.

You are "mainly interested in". Maybe you should put that in the policy then... And write down what the difference is between "commerce and similar/related activities" and things that are purely hobby, which I suppose is okay? We have been through this discussion a thousand times in relation to copyright and the non-commercial clause in some CC licenses and why it is bad because we can't differentiate between commercial and hobby use really. Why is this different here? Can we differentiate? The policy as it stands now certainly doesn't seem to make a distinction there. Back to the question of software and github repo names: The policy doesn't even mention "software" or "apps" as a category. So I look for the best fitting case which seems to me 4.3 "Publications" for which I would need a license. Is this a wrong interpretation? Do I understand you correctly that I can have a software with the name OpenStreetMap in the title in a github repo and it doesn't fall under this policy?

It seems to me this distinction is difficult to make in a legally strict form. Is one edit enough to be a community member? Or if you come to a mapping party? Traditionally the OSM community has been defined as "everybody who feels like they are a member is a member". But even if the new rule is somewhat stricter, "at least 3 edits" or whatever, this isn't something you can easily build legal distinctions on, because anybody who wants to subvert the policy can easily become a member by making this necessarily low hurdle. (And, by the way, I have seen much more activity from OSM community members than from outsiders that is giving OSM a bad name...) So the distinction has to come not from what you *are* (member or unrelated) but what you *do*. This distinction is used for two things in the document, one is about *what you are* "Community members are generally free to use all OSM marks for community-focused events" (1.3.1) etc. The other is about who the *objects of your activity are* (Community-focused events 3.1 etc). I think the second use makes sense, but the first use is a bit questionable and hides the fact that the community members have the same restrictions on what they can actually do than the outside people have.

To show why: there used to be an OSM based project called I think it is totally unrealistic to expect hobby projects based on OSM to ask for permission. I see three likely outcomes: * Most people will not know about the policy or they don't care and they might choose a name that doesn't follow the policy. It takes a while for OSMF to find out about this, get organized, and ask for a license application or a name change. By that time the people are already attached to their name. This will generate bad blood, not to mention what you are going to do if the people ignore OSMF. * People who know about the policy choose a name that doesn't violate the trademark policy. But they are outsiders now. They will avoid to even mention OSM, they will not feel as part of the community any more. We have always argued that everybody who does something with OSM is part of the community, you don't have to be an OSMF member, you don't have to have your service running on OSMF servers. This great eco-system is in jeopardy if you alienate all those people. * You scare people away from doing anything OSM-related because they don't know and understand what they are allowed to do and what not. I can tell you that I will certainly not apply for a license/permission for any of my hobby projects. In the worst case license means lawyers and money, in the best case it means I have signed something that promises I behave in certain ways. What if I do something unwittingly that oversteps the permission in that license I got. What if I change a website I got the license for in some way, do I have to get re-licensed? Sure, all those things are less problematic in reality than they are in the real world. But for a hobby project I don't need this. And there is always something down the line that comes back to bite you. Some of my projects have Debian packages for instance, which for many years called their "Firefox" package "Iceweasel" because of Mozillas trademark policy. (They recently switched back to the name "Firefox", I don't know what changed.) And again the question of the practicality of all this: Even if people have to get licenses and actually do, we are looking at at least several hundreds of projects (There are nearly 3000 repositories on Github that have "openstreetmap" in their name or description). Can the OSMF even handle this?

But it immediately opens a whole slew of questions for me, many of them concerning my own projects. * Section 2.1 forbids anything called something like "OpenThingMap". This form of name is very popular, there are numerous existing examples (OpenPOIMap, OpenTopoMap, OpenSeaMap, ...) Do all of these have to change their names? * I have a written an open source software called "OSMCoastline" (among many others), this clearly contains the "OSM" abbreviation. The use of this software is very specific to OSM data. It doesn't make sense for this software not to have OSM in its name really so much is it tied to the OSM data. Can it keep this name? There is no mentioning of software in the policy at all. * I am running the website openstreetmapdata.com where people can download OSM-derived data and only OSM-derived data. Currently all services there are free, we are only asking for donations (and receive almost none). But I want to reserve the right to charge for services there. The character of this site is in between a community site and something commercial. It comes out of my engagement for OSM and the OSM community, but it is not something run by the OSMF or so. It is run by me and Christoph personally and we might want to move it more into the direction of a commercial enterprise in the future. I know I am not alone with this, there are many sites that are half-open, half-community, half-commercial. And that is, in my opinion a good thing, because it is a way for OSM enthusiasts to move to something where they can make some money with what they are doing and sustain their services. But it raises the question of where community ends and trademark licenses are needed. It is quite clear from the policy that I can not keep using that domain name. What is not clear to me is how I have to do the wording on that site to keep within the Trademark Policy? Lets say I changed the site name to megaawesomedownloads.com, what else would I have to do? All the data on there is 100% derived from OSM data. I don't want to invent any bugus "product names", when I offer "OSM coastline data" for download, that describes best what you can download. Is a website a "Publication" in the sense of the section 4.3? If such a policy is introduced, I would hope that the OSMF provides some proactive guidance to the many many people already doing good things based on OSM and help them get into compliance. I fear many people will rather stop offering their services instead of understanding the legal issues involved. This is especially important, because - from my limited understanding of trademark law - it is necessary to actually defend your trademarks if you want to keep them. So unlike the data license violations which the OSMF can ignore as much as it wants to without limiting what they can do in the future, the OSMF has to actually defend its trademark. So if the OSMF says that, say "OpenSeaMap" is not according to our policy, it HAS to fight it (even if nobody really minds them using this name) to make this stick. So just ignoring some violations and fighting others isn't possible. Which opens the whole question of whether the OSMF is organizationally and financially in a position to actually do this fighting? If not, why have this policy?

Du kannst versuchen, auf die augmented diffs zurückzugreifen, die haben dann alle abhängigen Objekte in der alten und neuen Version drin.

Eine .osc-Datei enthält zu einem Way nicht unbedingt alle Nodes, die in diesem Way sind. Daher wirst Du mit diesem Ansatz immer Probleme haben. Was willst Du denn am Ende erreichen?

An outer way in a multipolygon relations should only have tags which apply to *that way* specifically, not tags which apply to the whole relation. The tags on the relation are for the polygon as a whole, the tags on the ways are for those ways. So if you have, say a wall surrounding a forest, you might have tags for that wall on the ways, but the forest tags belong on the multipolygon relation only. In most cases this simply means that there should be no tags on the ways at all. Of course you should still check all cases against sat images. For instance, sometimes the whole relation can be removed and just a simple closed way be used if there are no inner ways.

Canada stands out in a negative way, because a) there are so many problems. Nearly a third of the cases worldwide are in Canada and b) most of these problems are probably caused by one little program, the program used to convert/import the CanVec data. Mapping Canada "by hand" might be difficult because it is such a huge country and there aren't that many mappers. But the same arguments goes for why you have to be extra careful importing data. If you break something, there are not enough people to fix it manually. And, yes, errors do happen. And if we find them, we fix them and move on. But errors from imports can be so huge there aren't enough people there to fix them manually. So I think it is the job of those who did the import in the first place, to fix their work. If you add data to OSM you take on a certain responsibility. If you add more data, you have a larger responsibility. But saying: We don't have the manpower, so we are taking a shortcut and then, when it turns out the shortcut wasn't so short after all, whining that you don't have the manpower to fix it. That can't be the excuse.

Re: [Talk-ca] Multipolygon problems
Hi! A week ago I wrote this email and nobody answered it yet. Does that mean that nobody feels responsible for the import that created this data and nobody here cares for this data? I see three ways forward: * We do nothing. The broken data stays in OSM. Not a good solution, because every user of the data has to work around this or handle the complaints. * The Canadian community steps up and fixes the data, automatically or manually. * We ask the Data Working Group to remove the broken import.

Hi! Letztes Jahr hatten wir unser erstes Elbe-Labe-Meeting, dass Mitglieder der deutschen und tschechischen OSM-Community in Dresden zusammengebracht hat. Wir hatten Presentationen über Themen von Wanderkarten bis Auto-Navigation und viele interessante Diskussionen. Dieses Jahr planen wir etwas ein bischen anderes: Wir treffen uns in der Sächsischen Schweiz, einem Naturschutzgebiet, dass berühmt ist für seine Felsformationen und die vielen Wanderrouten, für ein Wochenende mit Wanderungen, Mappingaktionen, mit Gesprächen und generell allem rund um OSM. Der Spaß soll natürlich auch nicht zu kurz kommen. Wir haben ein Ferienhaus gemietet, das circa 20 Personen Platz bietet, Internet, Grill, und was man sonst noch so braucht, gibt es auch. Wikimedia Deutschland sponsort das Treffen, sodass es für die Teilnehmer kostenlos ist. Das Treffen findet vom 1. bis 3. September 2017 statt. Alle Details gibt es unter https://wiki.openstreetmap.org/wiki/Elbe-Labe-Meeting_2017 Wir laden alle OSMer ein, dabei zu sein. Da der Platz begrenzt ist, ist eine Vorregistrierung erforderlich.

[Talk-ca] Multipolygon problems
Hi! In the last days the OpenStreetMap Carto Style 4.0 is being deployed on the OSMF tile servers. This new version of the style doesn't take old-style multipolygons (where the tags are on the outer ways instead of on the relation) into account any more. In a huge effort in the last months we have converted all old-style multipolygons to the modern tagging, so this is a good step! Unfortunately, as a side-effect of this change, many multipolygon relations now appear wrong on the map. This is the case for multipolygon relations that have the same tags on the relation as well as on (some of the) outer or inner ways. This is *wrong* tagging, and needs to be fixed. (Note that this always was wrong tagging, even before we deprecated old-style multipolygons, but the way the software worked with old-style multipolygons, this problem was not visible on the map. But now it is.) Here is an example: http://www.openstreetmap.org/relation/1330741 . As you can see (unless somebody fixes this :-) the clearing in the forest that should just have grass, also has tree symbols on it. In many other cases it is not this obvious, there are just islands in a river missing or so. There are about 50,000 cases like this worldwide, forests, waterways, all sorts of areas. But the worst problem is in Canada. There are about 15,000 affected relations, most from the CanVec imports. First, we have to make sure that there are no further imports of broken data. I hope the people who have done those imports (and might still continue) are here on this mailing list. If not please make them aware of this issue and/or put me in touch with them. Second, somebody needs to clean up the broken data, either automatically or manually. 99% of the data has not been changed since the import, so it might be feasible to do an automatic cleanup, but somebody has to do this. Otherwise we'll have to do a manual cleanup, through tools such as Maproulette and the OSM Inspector. I am currently in the process of creating Maproulette challenges for other areas of the planet, but will not do this for Canada at this time. Lets discuss this here first. I can provide OSM data extracts, statistics, etc. if somebody wants to look at the data. All of this is part of a larger effort to fix areas in OSM. See http://area.jochentopf.com/ for more information. There is also a thread on the talk mailinglist at https://lists.openstreetmap.org/pipermail/talk/2017-June/078203.html and this issue https://github.com/osmlab/fixing-polygons-in-osm/issues/36 .

Es wäre ja schön, wenn wir die Arbeit der Mapper und der Entwickler irgendwie verrechnen könnten und schauen, was "unterm Strich" am effizientesten ist oder so. Das könnte man machen, wenn OSM eine Firma ist, die ihre Leute passend einteilen kann. Aber so ist das halt nicht. Das Problem ist ein anderes: Der Mapper denkt, sein komplexes Mapping würde auch magisch irgendwie verwendet. Es erscheint auf der Karte oder ist findbar im Nominatim oder wird beim Routing verwendet. Das ist aber häufig nicht der Fall. Wir sind meilenweit hinten dran mit der Entwicklung. Es gibt wahnsinnig viele Sachen, die theoretisch vielleicht möglich wären, die praktisch aber nicht funkionieren. Vielleicht gibts sogar Versuche hier oder dort, aber praktisch ist das, was wir von den OSM-Daten wirklich nutzen, ziemlich klein. Dadurch fehlt hier aber ein ganz wichtiges Korrektiv: Klassisch ist das so, dass der Mapper sich auf das stützen kann, was auf der Karte erscheint. Mapper mappen solche Sachen konsistent und qualitativ einigermaßen gut, wo sie das Ergebnis anschauen können. Ob das nun gut ist oder nicht, Mapper orientieren sich an der Karte (und auch an der Visualisierung der diversen Tools zur Qualitätssicherung). Aber da, wo es diese "guidance" durch solche Karten und Tools nicht gibt, gibt es einen unglaublichen Wildwuchs. Der Wildwuchs ist gut, wenn aktiv in dem Bereich etwas voran geht. So kann man nämlich verschiedene Dinge ausprobieren und dann das, was am besten funktioniert, systematischer umsetzen. Dazu braucht es aber irgendwen, der die Daten auch nutzt und sagt, was funktioniert und was nicht. Und das fehlt halt in vielen Bereichen. Beim public transport z.B. ist diese "Diskussion" noch voll im Gange, da bewegt sich was und neue Dinge werden probiert. Aber in ganze vielen anderen Bereichen, gerade was komplexe Relationen angeht, da passiert das nicht. Damit OSM als System funktioniert, das sich fortentwickelt und praktische Lösungen liefert, braucht es beides. Die Mapper, die Daten sammeln und erfassen und die Nutzer, die aus den Daten etwas machen. Aus dieser Zusammenarbeit entsteht eine nützliche Datensammlung. Fehlt das eine oder das andere, dann geht es nicht voran.

Es gibt da eine Tendenz immer komplexere Dinge zu mappen, ohne dass irgendwer diese Daten auch sinnvoll nutzt.

[OSM-talk] Old-style multipolygon cleanup is done!
Hi! The old-style multipolygon relations are history! In not even two months the OSM community cleaned up all of the nearly a quarter million relations. You can see the it here: http://area.jochentopf.com/stats/#old_style_multipolygons This is much faster than I (and probably everybody else) had anticipated. There are a few old-style multipolygons around, some of them have no members at all, some only relation members (which isn't allowed for multipolygon relations) and some have been created in the last days. I expect that we will get new ones occasionally from editors and/or mappers who don't know yet, that they shouldn't do that, but that's not a big problem. So that part of the great (multi)polygon fixing effort is done. Huge thanks to everybody involved! But there are still geometry errors to fix.

The map data is updated continuously from minutely diffs, but the map tiles weren't expired automatically, so you might well have been seeing old data. I have added a daily expiry now.

[Talk-us] Fixing Multipolygons
Hi! as some of you might have seen we have a huge effort going on to fix broken multipolygons and re-tag old-style multipolygons (those where the tags are on the outer way(s) instead of on the relation) into the current style. You can read all about it on http://area.jochentopf.com/ . As you can see on the map at http://area.jochentopf.com/map/index.html most of the old-style multipolygons now left are from some large-scale imports, including some in the US. We need your help in cleaning this up! I you have any questions, don't hesitate to ask.

I probably shouldn't have used the word "deprecated", because there is no mechanism in OSM do deprecate anything. This is more "common practice" really. Martin has already described why source tags on objects don't work well. In theory they might or might not be a good idea, but in practice we have seen in OSM that they don't work. The source tag is just not updated in a way that makes it useful. Since we introduced changesets, we can do better: We put the actual data into OSM objects, but the meta-data that describes the why and how of the mapping we put into the changesets. (I didn't know that iD doesn't allow you to set the source on the changesets as somebody mentioned. If that is true, I see this as a shortcoming of iD that should be fixed.) This has the added benefit of putting the meta-data that is seldomly used on the changesets keeping the actual OSM objects lean and mean. Now regarding the splitting up of changesets for different sources. If you are doing different things this absolutely makes sense and, I would argue, is even necessary to be able to add good changeset comments, which you should always do. So if you come back from a mapping survey and add the data you collected outside with source "survey" and then go to a different part of the planet and add a few things from "bing", those should be two changesets. Of course, if you add the geometry of a road from Bing and the name from your survey, it makes total sense to add the source "bing;survey" or something like it. As always, there are few hard-and-fast rules in OSM. That's good because everbody can decide for themselves which arguments they find convincing and which advice to follow. So if you want to keep adding "source" tags, that's fine, too.

Putting the sources on the objects has been deprecated for a while. The source should be put on the changeset only. If you are doing edits that involve several different sources, it is best to split the changes up into different changesets. Of course this is not always possible, then you can also put several sources in the changeset source tag. Adding the source to the objects was deprecated, too fined-grained source tagging simply doesn't make much sense. We can not track every source for every node, way, or relation or the parts of them for every tiny change that somebody does. In the end most data will have multiple sources and figuring out what came from what can only be done going through the changeset tags, not by looking at the tags on the data itself.

[OSM-talk] Broken multipolygons in South Korea
Hi! As you might know, I am on a "quest" to rid OSM of broken (multi)polygons. (See http://area.jochentopf.com/ for info about that and https://github.com/osmlab/fixing-polygons-in-osm/issues/15 for the news about that effort). I noticed a huge number of problems in South Korea, probably related to some kind of import. I have taken those out of the challenges I am generating, because I wanted to contact the OSM community there first. Anybody here who has connections to South Korea and/or knows about what's going on there?

Similarly woods inside woods, etc. "Inner rings with same tags as outer rings" is a subset of old-style multipolygons. Well, as you correctly point out, some of them might be okay, but most of them are especially "bad" cases of old-style multipolygons. And they are another good reason why we need to get rid of old-style multipolygons. There is just no way to figure out automatically, what's right here and what's not. So humans have to fix those.

Looking at the graphs on http://area.jochentopf.com/stats you can see that the number of (multi)polygons is growing steadily, while the number of errors has been more or less flat over the last half year. So either there are not a significant amount of new problems or old problems are being fixed as fast as new problems are introduced. Both leads me to believe that existing QA tools and/or better editors than we had historically keep this problem in check. But, as I said, we'll first need to get the number of errors down to low level and see how things look then. And maybe when there are less cases we can better see specific problems creeping up that can be solved by improving editors etc. Jochen -- Jochen Topf joc...@remote.org https://www.jochentopf.com/ +49-351-31778688 ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Every larger system that allows user contributions has a "report this as spam" button. If a few people click on that, an admin reviews and handles this. Sounds like an obvious solution that could also work for OSM. Not being able to report problems is frustrating to users. The whole question of who decides what is spam and what isn't is a bit besides the point here, isn't it? Obviously somebody is already handling this as you mention and it works. But what would help is a nice button.

So this doesn't really apply. Most of this is about cleaning up the backlog. If you look at the stats on http://area.jochentopf.com/stats/ you'll see that the number of (multi)polygons is growing constantly, but the number of errors is not. This tells me that it is mostly a problem with old data. We could inform authors when new problems are coming up, but I suspect that this is very difficult. For one, there can be several people involved and you don't know which fault is was. Then there is the question of what to tell the user. If you send them an email "Your multipolygon id 1234567 is broken", that is not very helpful for them. We need at a minimum some guidance on how to fix things. But this depends at least on the editor used, the language of the user, the type of problem and the skill level of the user.

We do not want to remove anything from the map lightly. We are doing this only after taking any measure we can to fix those cases. In the long run the situation will get better, because at the moment some of those "critical" polygons you are talking about might not show up or show up wrong on the map because of the errors they contain that the renderer is trying to fix and doing so in the wrong way. We are doing all this to improve the accuracy of the map!

Lets not get this thread hijacked by theoretical ideas about how to detect wooded areas. This thread is about broken multipolygons. The issue at hand here is that there are a lot of broken multipolygons out there. Some are probably from Corinne data. Now there are these options: a) Do nothing. Broken MPs will disappear once osm2pgsql switches. b) Remove existing MPs and start from scratch. c) Repair existing MPs. From some of the posts in this thread, c) doesn't seem to be a good option. Both a) and b) will result in those MPs disappearing from the map first, before things get better. In the case of a) they will all disappear one day, but the broken data is still there. In the case of b) we can go through them and replace them by better data piece by piece. I am willing to talk with the Swedish community (or any other) about how best to approach this. I can generate special Maproulette challenges for specific areas, in fact I think this is a better way then having generic challenges for the whole world. If you work on such a challenge, you might be thrown from an error in Borneo to one in Sweden to one in Antarctica. And the problems are different everywhere. I'd rather have more specific challenges addressing exactly one problem, for instance "Broken multipolygons of certain types of landcover data imported from Corinne in Sweden". That is something I can extract from OSM data and that I can explain to people how to fix after consulting with local mappers on how best to do this.

[OSM-talk] Fixing broken multipolygons
There are a lot of (multi)polygons in OSM that are broken in one way or another. And we have to fix them. While some of the broken ones appear on the map just fine, some don't appear and some mess up the map. And some of those that appear fine on the main OSM map will not show up on other maps where different software is used. A while ago I set up a web page at http://area.jochentopf.com/ and a Github repository at https://github.com/osmlab/fixing-polygons-in-osm devoted to that issue that I never announced properly. Go there and read up in more detail where the problems are and how we are going to fix them. Yesterday I launched several Maproulette challenges that allow you to easily help with the "cleaning up" effort. Read http://area.jochentopf.com/fixing.html for more details on those Maproulette challenges. This is a huge effort that will take a long time and we really need any help we get. The challenges posted today are only the beginning. They only show the about 6,500 ways worldwide tagged as buildings (with less than 100 nodes) where the way intersects itself. I have decided to start with a simple problem like this, to learn how the Maproulette stuff works and how well, you, the community, responds. Especially for beginners fixing those building is much easier than starting with 10,000 node multipolygons with possibly multiple errors in them. (If you want to, you can still do that. All multipolygon errors show up in the OSM Inspector areas view at http://tools.geofabrik.de/osmi/?view=areas ) Jochen -- Jochen Topf joc...@remote.org https://www.jochentopf.com/ +49-351-31778688 ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

[OSM-talk] Taginfo detecting wiki problems
Hi! every night when the taginfo update runs, taginfo parses changed key, tag, and relation type pages from the wiki and incorporates the information it finds into the taginfo database. And it finds lots of problems while doing that. Some are the fault of the taginfo parser, which is far from perfect. But many are the result of some error in the wiki. You can see the report here and use it to find and fix problems in the wiki: https://taginfo.openstreetmap.org/taginfo/wiki-problems A description of the messages seen is here: https://wiki.openstreetmap.org/wiki/Taginfo/Parsing_the_Wiki Jochen -- Jochen Topf joc...@remote.org https://www.jochentopf.com/ +49-351-31778688 ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Interpolation was only intended as a way to get going quickly and easily with lots of addresses. And it has another use: Some non-OSM data sources use a format where a "street" has attributes giving the house number range on the left and right side. This can be reasonable easily be transformed into the addr:interpolation format for importing that data into OSM. It is here like with everything in OSM: There is a trend towards more detail. If you have more detailed information, great. If not, it is better than nothing.

[OSM-talk] Taglists support for rendering examples
Hi! I have now added support to taginfo for showing an example rendering in the taglists on the wiki. If the "osmcarto-rendering" field in the KeyDescription or ValueDescription info box template is set to an image link (typically something like "Image:foo.svg" or "File:foo.svg"), this image will show up in taglists if the taglists have the "with_rendering=true" parameter. A detailed explanation is at: https://wiki.openstreetmap.org/wiki/Taginfo/Taglists Note that the "osmcarto-rendering-size" setting in the infobox is not used. That setting is really not neccesary if the icons have been written in the right way. If you look into the SVG of the icons you'll see the difference: The correct SVG looks something like this: The incorrect SVG looks something like this: So you have to explicitly set the right size. This is a common problem with many icons and they should be fixed in the original repository at https://github.com/gravitystorm/openstreetmap-carto and then re-imported into the Wiki. (And yes, it would make sense if we didn't have to copy the images into the wiki, but there are more issues with that. I am trying to do the next step here, not change everything in one go.) With this change the taglists can be made to look exactly like the old, manually created ones (for instance on the MapFeatures page).

Our "main map", the one with what we used to call "mapnik style" and now sometimes call "osmcarto style" or so is somewhat special. It is the only "general" style that we have that explicitly tries to show as many features as possible. And there is the precedence of showing this style (and this style only) in the tables on the Map Features page and in other places on the wiki. So I think it is not totally wrong to argue that this style is special and is the only style we present in the Info Box and/or Map Features page. But I also agree with your argument that it would make sense to show more styles. For taginfo it is easiest to get the information out of the Info Box. It is also easy to get the info out of the projects json files it already collects. But if we agreed on some different format, that is also something taginfo could support. So which mechanism we choose should not depend too much on what's convenient for taginfo. Taginfo is software that we can change and the effort involved is likely to be small. The effort of maintaining all those icons is much larger. Ideally it is done somewhere, where lots of people can help. At the hack day at SOTM Matthijs and I threw around some ideas on how to best get those icons into taginfo and back out and had the idea that it doesn't make much sense importing all those icons manually into the wiki when they are already in a git repository somewhere. We thought about including the URL of the icon in the info box. But now with your proposal, maybe it makes more sense to leave the wiki out of it completely and just collect the icons all into some format (basically a map legend) and let taginfo read it from there (and then maybe export it into the wiki through the taglists feature). As you mention, we already have a format that would support most of this (the taginfo projects json files). On the other hand all of this leads down the rathole of automatically generating a map legend. It should be possible to create the list of icons more or less automatically, but nobody has ever tried actually implementing this. We can not delay introducing taglists because we are waiting for somebody to implement legends, because this might never happen. Yes, there are better ways of handling all this than copying icons into the wiki manually and all this. But we are trying to solve one problem here (the overcomplex and huge tag lists we manually create) and we can't solve all the problems at once, otherwise we will never get anywhere. So I think the way forwards has to be the simplest thing we can do so that we can actually finish the current task and then, after we have done one thing, we can think of tackling the next one. All of this brings me back to the first proposal: Just put the icons into the info box (we don't even have to display them in the info box, the template that creates the info box is just a convenient place to put this data). Then taginfo gets the data from there and puts them into the list. This is the short-term solution that would allow us to have the same Map Features page we already have, with a hugely reduced (but not totally removed) maintainance burden. Long-term somebody has to implement map legends which taginfo can then understand.

No, count isn't a criteria at all. man_made=mill is simply not included automatically, because there is no wiki page for it. I recommend giving an explicit list of all tags that you want to have in your list. Just using the key only is more of a short-cut to help get you going. In my opinion it makes sense to have a human edit the complete list of everything they want to have in that list. That is the power of the wiki after all, that it is not autogenerated, but somebody actually curates this list. Taginfo should only be the helper here that makes it easier, but it shouldn't decide what ends up on that list and what doesn't.

Just looked at this and it isn't the greatest format for parsing by taginfo due to the wiki-specific syntax: osmcarto-rendering=[[File:Supermarket-14.svg|14px]] Could we make it like the "image" attribute instead, just the name of the image file? image=Image:Sainsbury'sGlos.jpg Or a real URL?

This is a good idea. Historically the "Rendering" images on the Map Features page were often very bad and not well maintained. But looking at it now, it looks quite good, especially for POIs. So, if somebody adds the rendering to the infobox (and tells me about it), I'll pull that data from taginfo and can put it in the taglist tables.

A solution using Taginfo has been available for about a year now, but nobody took this up. (I guess because not many people know that this exists, and I didn't have time to promote it really.) See https://wiki.openstreetmap.org/wiki/Taginfo/Taglists . This "just" needs some people going through every tag list in the wiki and replacing it by the special syntax. The problem ist, as you say, the differing descriptions and such, which need to be consolidated in the process.

I totally agree that the manual maintainance is a nightmare. That's why I added the "TagLists" function to taginfo, which can more or less automatically create such feature lists from the descriptions of the tags in the info boxes on the individual key and tag pages. See https://wiki.openstreetmap.org/wiki/Taginfo/Taglists for all the details. Unfortunately I din't have the time to persue this and nobody else worked on integrating this into the wiki on the MapFeatures and other pages. But the feature is finished and working. It is "just" a matter of replacing the old manual lists by the template. The largest effort is consolidating the descriptions and/or images from the individual key and tag pages and the lists on MapFeatures. Where those descriptions/images are not the same it might make sense to update the descriptions on the individual pages to not loose the possibly better descriptions from the MapFeatures list.

I'd tag these as separate buildings ignoring what's underneath. That's how most people will see those buildings. If you don't look closely, you don't know that they are connected. As for the address, just put the same address on all buildings if they actually have the same address.

Re: [Talk-de] Wann geht eine Bahnstrecke in Betrieb?

Ich gehe hier mal vom Otto-Normal-Mapper aus, der keine speziellen Fachkenntnisse hat. Der guckt sich an, wie etwas aussieht und mappt das dann. Das ist unser Massstab bei OSM. Der sieht eine Bahnstrecke, die fertig aussieht und auf der gelegentlich Züge hin- und herfahren. Dann macht es keinen Sinn, das als construction zu taggen. Das ist ne Bahnstrecke. Ob die Strecke laut Bundeseisenbahnbaundbetriebsgesetz Paragraph 08/15 offiziell in Betrieb ist oder nicht, das ist eine Frage, die für OSM erstmal keine Rolle spielt. Bei einer noch nicht eröffneten Strasse ist durch einen Laien ohne weiteres ersichtlich, dass sie nicht offen ist, weil sie durch entsprechende Schilder und Absperrungen so gekennzeichnet ist. Bei einer Bahnstrecke ist das nicht unbedingt der Fall. Und auch wenn ich mir anschaue, wie das vom Benutzer der OSM-Daten aussieht, komme ich zu dem gleichen Schluss: Wenn ich mich im Gelände orientiere und sehe eine hübsche neue Bahnstrecke, die in der Karte gestrichelt gemalt wird, dann sieht es für mich aus, als ob die Karte veraltet ist, oder ob ich vielleicht an der falschen Stelle bin. Liegt da überall Baumaterial rum, dann erwarte ich was anderes. Routen kann man auf Bahnstrecken eh nicht in der selben Form, wie man das auf Strassen kann. Nur weil eine Strecke offiziell freigegeben ist, heisst das ja nicht, dass da auch Züge fahren. Also ganz klare Antwort: Umtaggen, wenn es für den Laien so aussieht, als ob die Strecke fertig ist. Das ist einfach nur eine weitere Form der "on the ground rule". Spezialinteressen haben bei OSM gegenüber dem, was allgemein nützlich und erwartet wird, zurückzutreten. Meiner Ansicht nach gehört die Information, welche Strecken offiziell freigegeben sind, überhaupt nicht nach OSM, weil es eine Spezialinformation ist, die sich "on the ground" nicht verifizieren läßt. Aber ich werde mich jetzt auch nicht beschweren, wenn die Eisenbahnmapper dafür einen besonderen Tag erfinden.

Re: [Talk-de] Offene Geodaten in Sachsen - Bitte noch abwarten
Hallo Joachim, Du solltest von jeder Eile absehen. Die bezeichneten Datensätze nutze ich teilweise seit Jahren. Sie sind z.T. in Online-GIS eingebunden und wer die Zugänge kannte, der konnte sie als WMS in sein GIS einbinden. Seit Jahresbeginn wurde auf https umgestellt und damit einhergehend eine Liste der WMS publiziert. Ob damit ein Lizenzwechsel verbunden war, kann ich nicht sagen. Als Anwender kann ich nur sagen, dass die meiste Zeit mittlerweile für die Validierung von Datensätzen verwendet werden muss und nicht für deren Beschaffung. Gelangen Fachdaten in OSM, sind sie nur schwer hinsichtlich Vollständigkeit, Alter etc. zu prüfen. Der Kampf mit / gegen Datenmüll ist bereits Alltag. Auch Geometrien sind nicht genauer, wenn sie aus einer Datenbank kommen. Praxisbeispiel aus OSM: die bekannte Datenaufspielung aus NRW von regionalen Straßendaten; darin für eine Teilregion Kreistraßen als 100prozentiger Match mit einem lagekorrigierten amtlichen Luftbild, die untergeordneten Stadtstraßen signifikant verschoben und gedreht. Vermutung: aus kommunalen Altkartenbeständen digitalisiert, falsch referenziert oder umprojiziert, erst später gejoint. Über Sachdaten kann sicher jeder irgendwelche Stories erzählen. Ich finde, WMS etc. sind eine gute Grenze zwischen OSM und den Amtsstuben. Die Mitarbeiter der Fachämter sollen sich auch nicht als wohlmöglich überbezahlte Mapper fühlen müssen.

Da steht nur die Behauptung "Damit sei auch eine langjährige Forderung der OpenStreetMap-Community erfüllt." Das kann ich so nicht nachvollziehen. Was genau war denn diese Forderung? Sicher ist es besser, dass die Daten so rausgegeben werden, als dass es sie nur gegen Geld gibt. Das freut uns natürlich. Aber nutzbar sind sie so für uns immernoch nicht. Und selbst wenn in der Presseerklärung mehr drin stände, eine Presseerklärung ersetzt keine klare juristische Aussage der zuständigen Landesämter. Ich kann die Datenlizenz Deutschland – Namensnennung – Version 2.0 nur so lesen: Wenn man die Daten irgendwie nutzt, dann muss man die Quelle (LGL bzw. halt das Land Sachsen) erwähnen. Diese Forderung "vererbt" sich bis zum Endnutzer der Daten. Wenn die Daten aber mit unseren vermischt werden in OSM, dann fordern wir hinterher nur noch, dass OSM genannt wird. Und damit ist das ganze inkompatibel. Für mich ist also weiterhin klar: Wir dürfen diese Daten nicht in OSM importieren. Da hilft kein rumreden. Entweder die Ämter ändern die Lizenz komplett oder sie geben uns eine klar formulierte Sonderlizenz. Wir haben dieses Thema doch schon tausendmal gehabt mit anderen Datenquellen. Wir brauchen eine juristisch einwandfreie Aussage, dass sie damit zufrieden sind auf http://www.openstreetmap.org/copyright in der Liste der Contributors genannt zu werden und dass sich darin dann ihr Recht auf Namensnennung erschöpft. Wenn Sie das unterschreiben, dann ist das okay, vorher nicht.
