OpenStreetMap Isn't All That Open, Let's Change That and Drop Share-Alike about 1 month ago

Even though I don't agree with every single argument made in the diary entry, I would appreciate if OSM adopted a different license along the lines of the CC-BY or even CC0 (although the latter is probably not realistic).

It may not be obvious to everyone, but as soon as you try to build something with OSM beyond mainstream use cases like 2D rendering, the ODbL frequently becomes a highly annoying obstacle. I was under the impression that OSM was supposed to enable a broad range of commonplace and creative uses, but the current license hampers that mission.

Money for OSM about 2 months ago

Thanks for your effort maintaining this source of money for OSM, Malenki! I try to use the affiliate ids whenever possible.

Zuviel des Guten about 2 months ago

Ich finde Detailverliebtheit nicht einmal das Problem in diesem Fall - wenn dadurch wirklich nutzbare Daten hinzukämen, könnte man gerne Gehsteige separat mappen. Das eigentliche Problem ist, dass die Frage der praktischen Nutzbarkeit komplett ignoriert wird und daher sogar Funktionalität verloren geht!

Konkret: Wie soll der Router bei getrennt gemappten Gehsteigen noch wissen, dass ich eine verkehrsarme Straße an jedem Punkt überqueren kann? Wie soll er noch "folgen sie der X-Straße auf der rechten Seite" ansagen können? Wie soll ich im Renderer - 2D oder 3D - lückenlos an die Straße anschließende Gehsteige als solche darstellen können?

Mit sidewalk-Tags ist alles oben genannte möglich, mit separaten Ways nicht. Wo ist da die Verbesserung?

iD Newbie friendly feature request about 2 months ago

Perhaps there should be some kind of integration with GeoChat for JOSM, too?

Openstreetmap und Wikidata 2 months ago

Sehr schönes Beispielprojekt, zeigt gut die Möglichkeiten, die in Wikidata stecken! Seit ich Wikidata entdeckt habe, bin ich absolut überzeugt, dass sich da Synergien zu OSM ergeben müssen.

Anders als du würde ich mir allerdings schon wünschen, dass wir doppelte Arbeit weitgehend vermeiden, eine Ähnlichkeit mit Wikipedia-Relevanzdiskussionen sehe ich beim Wunsch nach Koordination zwischen zwei freien Projekten auch nicht gegeben. Meiner Meinung nach ist OSM von der Software und Kultur her am besten für Recherche vor Ort geeignet – und natürlich generell für geografische Daten. Wikidata wäre eher für Dinge, die man über Quellen- und Literaturrecherche findet. Nach dieser persönlichen Abgrenzung sehe ich dann auch population (inklusive historische Bevölkerungszahlen etc.) eher als Aufgabe für Wikidata.

Trotzdem hast du natürlich recht, dass man Zugeständnisse für technische Anforderungen machen muss.

OpenStreetMap - Increasing diversity 2 months ago

I would like the OSM community to become more diverse, but I would not like the foundation to choose goals – no matter how noble – and impose them onto the community. The current activities of the Wikimedia foundation are actually a rather negative example in my opinion, because they appear to be done mostly in a top-down fashion, the exact opposite of how a community-driven project with minimal formal organisation should work. Your ideas feel similar to me, so I'd rather not see them implemented, sorry.

"Anyway, as you say it's a do-cracy. And I have mapping parties to organise..."

That's the spirit! :-)

Attribution and all that (a rant) 3 months ago

Well, if we dropped the various restrictions regarding the precise appearance of the attribution, we could magically turn a lot of incorrect attribution into correct attribution overnight. I feel it is generally irrelevant whether the attribution says anything about "OpenStreetMap Contributors" or just "OpenStreetMap", whether it includes the © sign, and whether it is in a corner of the map, on the bottom of the page or behind a link. The proper attribution for OSM looks exactly like the usual legalese you see on the internet all the time, so users will habitually ignore it anyway.

What brings in new mappers is when an application is nice enough to dedicate a popup or two to alerting its users to OSM, or when the developers blog about it, or when users recommend the great OSM map files to each other, or if the application is popular enough to get us press coverage. Attribution helps very little with all that, except for one thing: It serves as an easy proof that this cool application is made with OSM data, which can be helpful for our own PR and recruiting efforts. But having an "OpenStreetMap" anywhere that we can point to is enough for that purpose.

tl;dr: Let's focus on those who do not provide attribution at all, and relax about the details.

What to do to avoid such fake accounts 4 months ago

As a first step to combat the spam it would be helpful to introduce a way for users to easily "flag"/"report" spammy user pages and comments so that they can effectively be dealt with. Such a functionality is built into the forum software, but elsewhere it's always quite cumbersome to actually bring it to someone's attention when I see spam.

What does the path say? 5 months ago

@Diomas: No, highway=path has nothing to do with "informal" paths - use informal=yes for that. The "path" value can be used for for basically all sub-car highways. Based on the original definition of higway=path, you could technically replace all highway=footway/cycleway/bridleway with highway=path (although the article explains why this might not be a good idea).

Just seen an excellent real-time 3D map of Openstreetmap, the F4 map. 6 months ago

There's a few more example areas of varying quality listed here: http://wiki.openstreetmap.org/wiki/Simple_3D_Buildings#Demo_areas

OSM in 3D 9 months ago

In my biased opinion, OSM2World deserves at least a mention, too. ;)

See: http://maps.osm2world.org/?zoom=18&lat=53.62456&lon=11.41839

No WebGL interactivity and animations (yet), but textures, building levels and a few other features.

OpenStreetPOIs 9 months ago

You will occasionally get multipolygons even for amenities, shops and the like. Some examples (found via overpass turbo):

Compared with ways and nodes they are of course quite rare – Taginfo says that 0.06% of shops are relations, and about 1% of amenity and leisure features. It's up to you whether you think including them is worth the effort.

(Sorry for the slow answer, expected to be notified about replies somehow.)

OpenStreetPOIs 9 months ago

You don't mention relations. Does your code handle POI mapped as multipolygons, specifically if the tags are on the relation instead of the outer ring?

tagging a green roof? 11 months ago

How about roof:material=grass?

Extending to JOSM about 1 year ago

Regarding OSMI: There were some server problems apparently, but it should now begin to work again according to a Forum post by Frederik (in German).

Höhenmeter about 1 year ago

Höhenlinien werden derzeit nicht direkt in OpenStreetMap eingetragen. OSM-Anwendungen, die so ein Feature anbieten, nehmen die Werte normalerweise aus Quellen wie SRTM oder OpenDEM.

In OSM gibt es zumindest den Schlüssel ele, mit dem man einzelnen Punkten eine Höhe spendieren kann. Leider herrscht dort ein bisschen Chaos, was das Messsystem der Werte angeht. Und die Werte werden – soweit ich weiß – von bisher existierenden Anwendungen auch nur zur Beschriftung von Berggipfeln o.ä. eingesetzt.

How can I add tags to traces that I have already uploaded? about 1 year ago

Go to http://www.openstreetmap.org/traces/mine which is a list of traces you have uploaded. Click at the file name of a trace. At the bottom of the overview page for that trace, there is an edit button. Click it. You will now be able to edit the description, visibility and tags of the trace. Do so, then click the save button below the text fields.

@Chaos99: vVvA has already contributed and tagged several nodes and ways, so I'm going to assume that this question is indeed about adding tags to traces, not about adding tags to map elements.

Guided Tagging by Wiki generated JSON-formated rules about 1 year ago

I think what you describe in your post is indeed something that should be implemented and would be very helpful for OSM.

Maybe I can help. I'm actually using a bot to extract template data from the wiki already. Right now I'm doing this for the software templates. The software catalogues have been kept up to date using this automated process for years.

Rewriting this as a more general framework for template extraction (preferably in a programming language that is more popular among OSM developers) has been on my todo-list for quite a while - there are several unrelated ongoing projects I would need this for. But once that tool exists, it could be easily used to expose the data from key/tag description sites as JSON, too.

1 Million Mappers Soon ... No, Not Really over 1 year ago

Like other commenters, I disagree with the idea to delete accounts without map edits. For one thing, it is known that some people only start mapping months after they have registered their account. Furthermore, OSM accounts are needed for other services than mapping: Posting in the forum and on help, uploading gps traces, or even just storing your preferences for osm.org. Thus someone who is not a mapper might still be actively using their account - e.g. a developer using OSM who participates in forum discussions.

If the problem is that "find nearby users" is too cluttered with inactive accounts (and I actually agree with that), then the solution is to filter the accounts showing up there, not to delete them entirely.

In communication, reporting the number of people who have actually mapped something, rather than the number of registered users, would indeed be preferable. But that would be possible even today.

OSM and your city's wiki over 1 year ago

Here in Passau, Germany, we mostly just use the wiki write down links and topics from our meetings: Passau/Mappertreffen (Google translate), though we have a landing page with the usual template, current events (if any) and embedded slippy map, too.

These meetings are also our primary means of coordination, along with the occasional email on our local mailing list. Passau is quite small and we usually get just 3-6 visitors.

Years ago, there was an attempt to establish "mapping status" tables on the wiki. While it seems to have been adopted by a few places quite well, it doesn't really work for us and is unfortunately barely maintained now. What did work, though, was an automated comparison with an official list of street names that helped bring down the number of unmapped streets. I think it mostly worked because it didn't require any additional effort once it was set up: You just mapped a street and it would disappear from the list.
