Available languages — Wochenaufgabe

The Wochenaufgabe @osmwa is the Weekly Task of the German OSM Blog (Category:Wochenaufgabe).

Every 1-2 weeks they present a new task to encourage users to map in the following days. Everybody can suggest these tasks (blog@openstreetmap.de). Usually they are small POIs like a charging station or certain type of vending machine.

Switch heatings KW 1/2

Geothermische Weichenheizung BHF Vilseck.jpg

Because large parts of Germany were coverd by snow for a few days, German OSM Blog asked mappers to map switch heatings. They can only be detected if there is snow between the rails. If the heating is on/existing, the snow melts at the switch while it keeps frozen at all other locations.

Public transport changes due to anual timetable change KW 51/52


Every year at the second weekend in December timetables in Germany and many other European countries change. During this weekly task changes were done in OSM and public transport routes were changed to current Public Transport Version 2 mapping scheme.

The blog post includes a long description of current public transport mapping in German.

More information see:

Turning indications per lane KW 47/48 (2014-11-19 – 2014-11-30)

U turn A2 Lithuania.JPG

A more demanding task asks contributors to dive into the challenges of tagging more complex road intersections where road markings and/or signs indicate the direction in which a way or a lane will lead. This will help routing engines to actually use turning lanes.

The blog post includes an extensive description in German, a comprehensive tagging description in English (as well as DE, FR, HU, PL and RU) is also available in the wiki.

Recycling KW 43/44 (2014-10-22 – 2014-11-04)


This weekly task is about tagging recycling container or centre, in particular the materials you're able to recycle.

For tagging, please see description in blog (link below)

Proposals for future actions


While running an action, the documentation in the Wiki should be consolidated and updated.

Trello Staging / Stati in Trello

The Wochennotizteam plans the Wochenaufgaben with Trello. https://trello.com/osm_wa. The cards are public.

There are several card stages defined:

Ideen (unvollständig) / Ideas (incomplete)
Everything suggested as Wochenaufgabe can stay here. But the ideas has to be precised, so that they can fit into the 2 weeks Wochenaufgabe format.
Ideen (Owner gesucht) / Ideas that have no owner
The idea is so concrete, that it can be run as a Wochenaufgabe. There is no owner, that does the necessary staff to run the Wochenaufgabe yet.
Ideen (mit Owner) / Ideas that have an owner
The idea is so concrete, that it can be run as a Wochenaufgabe. There is an owner, that is willing to formulate the text for the Wochenaufgabe and takes care about the definition of the tooling.
The idea is missing the text, and/or - if necessary - a tooling.
Erstellung Text / Tooling / preparation of text and tooling
The text and tooling preparation is in final stage, the Wochenaufgabe will be prepared for the final go live in this stage.
WA terminiert / läuft / Wochenaufgabe scheduled / running
Everything is fine, the Wochenaufgabe has a concrete date, when to start, or is already running
Nachlese schreiben / pickings have to be written
After a Wochenaufgabe has been run, there should be a small summary which contains, what went well.
Abgearbeitet / Done
Fine everything is done, OSM Quality is better now. Everyone had fun (we hope) and the Wochenaufgabe is waiting for rerun.

Future Wochenaufgaben

Completing hotel information by website, phone and e-mail

Motivation: When looking for a place to stay, commercial booking services deliver only limited geographical information. With a simple overpass API call http://overpass-turbo.eu/s/4TM, hotels in a specific area are delivered. It then would be nice to have the contact information readily available. This project actually should be done world wide. --Fx99 (talk) 05:31, 4 September 2014 (UTC)

100k new addresses in Germany

Motivation: obvious--Fx99 (talk) 05:31, 4 September 2014 (UTC)

from building=yes to something more useful

Motivation: The standard for mapping buildings seams to be still building=yes This could be done a lot more precise taking the tagging scheme in the wiki: http://wiki.openstreetmap.org/wiki/Key:building --Fx99 (talk) 05:31, 4 September 2014 (UTC)

also building levels, colors roofs could be added in this shape to make maps like this more nicely: http://demo.f4map.com/#lat=48.1368676&lon=11.5757716&zoom=17&camera.theta=58.628&camera.phi=-34.238 --Morray (talk) 18:59, 11 September 2014 (UTC)

from surface=paved or surface=unpaved to something more precise

As already mentioned in surface=*: use a more precise value if possible
Overpass-Query: http://overpass-turbo.eu/s/4UU -- Haribo (talk) 06:01, 5 September 2014 (UTC)

Amenities/shops which lack an opening_hours tag, but have a website tag

As proposed by user ypid in his diary: Often the opening hours can be found on the website. This can be done remotely and worldwide.

Map (by ypid, too): http://openingh.openstreetmap.de/?setLng=en

Overpass-Query: See diary for the current version.


Bei mit access=designated oder access=destination getaggten Ways die Beschilderung prüfen

Grenzen mit Landuse und Straßen

Ways mit boundary=* von Ways mit z.B. landuse=* oder highway=* trennen (besonders schlimm in DE-RP)

beinahe Verbindungen korrigieren

Die Wochenaufgabe soll eine vor einem Jahr durchgeführte "Wette" wiederholen, bei der beinahe Verbindungen mit keepright korrigiert werden. Der Weg muss entweder verbunden werden, oder ein noexit=yes dran oder (wenn man es von der Couch nicht lösen kann) der Fehler evtl. in OSM-Notes gemeldet werden.

Eine Beschreibung hierfür existiert bereits. Der Einsatz des QAT Scripts verwandelt das Korrekturerlebnis wie eine Maproulette-Challenge (wo es damals im Übrigen darum ging, beinahe Verbindungen in ganz USA zu korrigieren).

Motivation: Routingfähigkeit der (im Sommer erfassten) OSM-Daten wieder herstellen! Wenn die Wege nicht verbunden sind, können (bspw. Abkürzungen) nicht geroutet werden.

Was brauche ich: jemanden, der eine Overpass-Abfrage erstellen kann und eine kleine Statistik führt (oder mir sagt wie das geht). Möglicherweise wieder als Wettbewerb der Bundesländer. Den Support im Forum kann ich übernehmen. --Poppei82 (talk) 07:41, 11 September 2014 (UTC)

Kannst du in kurzen Worten beschreiben, was die Overpass Abfrage leisten soll? Couchmapper (talk) 13:43, 14 September 2014 (UTC)

Fehlende fire_station mappen

--Fx99 (talk) 09:21, 14 September 2014 (UTC)

siehe http://forum.openstreetmap.org/viewtopic.php?id=26968

Beispiel Hessen: http://overpass-turbo.eu/s/51A

Eine verbesserte Overpass API-Abfrage findet sich in der Overpass API-Beispielsammlung. Relevant ist hier die Variante mit map_to_area. Mmd (talk) 17:36, 7 April 2015 (UTC)

Standorte von Feuerwehrhäusern lassen sich oft mit google finden, indem man "FF <Gemeinde/Ort>" im Netz sucht. Viele Feuerwehren haben Webseiten. Und wenn sie dann noch ein Foto des Gerätehauses haben, kann man meist das Haus auch aus der Entfernung zuordnen, wenn das Luftbild gut ist. --Gormo (talk) 07:27, 13 October 2014 (UTC)

Erfassen von Fahrspuren

--hurdygurdyman (talk) 09:13, 10 October 2014 (UTC)

Siehe: https://drive.google.com/file/d/0B_3PJBM5cOz5dUlXSUt1d29FXzg/view?usp=sharing

Die umfassende Erfassung von Fahr-/Abbiegespuren in OSM eröffnet die Möglichkeit, auf Basis der OSM-Daten Fahrspurassistenten in Routern als Alternative zu kommerziellen Anbietern weiter zu entwickeln.

Hast du die pdf erstellt? Beim ersten Bild ist "Lanes:backward" jeweils groß geschrieben.
Übrigens unterstützt OSMAND seit neuestem turn:lanes. http://osmand.net/en/blog/96-osmand-19-released.html Testen konnte ich es allerdings noch nicht. --Klumbumbus (talk) 13:48, 10 November 2014 (UTC)

Diesen Abschnitt könnte man jetzt eigentlich archivieren, oder? --zarl (talk) 14:19, 30 November 2014 (UTC)
