Status of WIWOSM?


I wanted to ask what the current status of the WIWOSM project [1] is.
It seems that there hasn't been a data update since March 2015 as
reported via [2, 3].

Is this due to technical problems or does the project lack of maintainers?

Thanks in advance and best regards from Austria,

Maps on Wikipedia

Is there a way to get an extension to display the tile server on
wikipedia? It would be useful to be able to display dynamic maps (with
something like a GeoJson) instead of static SVGs. I know the roads
project would find this extremely useful.

Announcing the launch of OSM Maps for Wikipedia

Wikimedia Foundation has implemented a new vector tile service Kartotherian (Mapbox+Mapnik stack) and launched an experimental tile and static maps service available at Using this service, you can browse and embed map tiles into your own tools using OpenStreetMap data. Currently, we handle traffic from * and * (referrer header must be either missing or set to these values) but we hope to open it up to Wikipedia traffic if we see enough use. 

Tiles are served from, but can only be accessed from * and *  Kartotherian can produce tiles as images (png), and as raw vector data (pbf Mapbox format or json):{source}/{zoom}/{x}/{y}[ <at> {scale}x].{format}

Additionally, Kartotherian can produce snapshot (static) images of any location, scaling, and zoom level with{source},{zoom},{lat},{lon},{width}x{height}[ <at> {scale}x].{format}
For example, to get an image centred at 42,-3.14, at zoom level 4, size 800x600, use,4,42,-3.14,800x600.png  (copy/paste the link, or else it might not work due to referrer restriction).

Editing map style is very easy using the Mapbox Studio, and does not require any data on your machine - simply point it at Wikimedia server.

How can you help?
* Provide us feedback to help guide future features
* Improve our map styles
* Improve our data extraction
* File bugs in Phabricator
* Adapt your labs tool to use this service - for example, use Leaflet js library and point it to

Based on usage and your feedback, the Discovery team will decide how to proceed. We could add more data sources (both vector and raster), work on additional services such as static maps or geosearch, work on supporting all languages, switch to client-side WebGL rendering, etc. Please help us decide what is most important. has more about the project and related Maps work.

We would like to thank WMF Ops (especially Alex Kosiaris, Brandon Black, and Jaime Crespo), services team, OSM community and engineers, and the Mapnik and Mapbox teams. The project would not have completed so fast without you.

WikiDACH 2015 - Wikipedia tut gut

Vom 30. Oktober bis 1. November 2015 findet nun endlich im prächtigen Schweriner Schloss [1] 
die erste WikiDACH [2] statt. Der Landtag von Mecklenburg-Vorpommern gestattet die kostenfreie 
Nutzung damit sich die Welt der Wikipedianer (und aller anderen Wikimedia-Projekte) mit den 
Menschen der Region, sowie ganz Österreichs, der Schweiz und Deutschlands austauschen können. 
Teilnehmer können hier ihr Interesse bekunden [3] und es werden noch Helfer [4] gesucht. Wer 
einen Vortrag oder Workshop [5] anbieten möchte, trägt sich bitte ein. Bitte beschreibt, was 
Ihr anbieten möchtet. Ein griffiger Titel ist dabei sehr wichtig, außerdem natürlich das Format 
und die gewünschte Länge des Slots. Da wir viele Besucher erwarten, die die Wikipedia und ihre 
Schwesterprojekte noch nicht kennen, wäre auch eine Angabe hilfreich, ob sich der Slot für 
Anfänger eignet.

Help needed to finish finding the maps in the BL Flickr stream. 11, 000 maps found so far in first 50%.

Hi everybody,

A quick update on the campaign to find all the maps (and ground plans) 
in the British Library's one-million-image Flickr stream scanned from 
old 19th century books.

This is of particular relevance to the Wikimaps project, because as soon 
as we've tagged all the maps and plans on Flickr, the BL will start 
georeferencing them with its own loyal volunteers, so that in the new 
year we should be able to upload all the maps to Commons, complete with 
a full set of georeferencing control points.

The good news is that in the first ten days, we've gone through the 
Flickr pages for half the books scanned for the collection, and tagged 
11,000 maps and plans, ready for georeferencing.

See latest status here:

The bad news is that the effort so far has almost all been made by about 
ten people, who are now starting to tire.  So the project desperately 
needs more help, if we're to push on and get all the old maps found.

As the status page above shows and links, a lot of progress has been 
made with many parts of the index; but some other parts -- for example, 
index pages of books relating to the United States, and to Scandinavia 
-- still remain almost untouched.

What's needed is very simple.  As explained on the status page, it's 
just to go through each entry that has a pink "Untagged maps?" templated 
link, tag all the images that are maps, then remove the templated link 
from the list on the wikipage.

This should produce an excellent resource for the Wikimaps project.  But 
first we need to identify the maps, so the British Library can 
georeference them.

So if anyone on this list knows anyone who might be interested to help, 
or if anyone could organise a group to help, please do let them know (or 
even please do help with a bit of tagging yourself).

It would be so good to get all the maps and charts and plans found in 
this collection.  But it's going to need a bit more help.

All best,

Looking for 10, 000 maps in the BL flickr stream, from Friday 31 October. Help needed to get the word out.


This is to let everybody know about a campaign to try to find 10,000 
digitised maps 'hidden' in 13,000 books in the set of a million images 
that the British Library uploaded to Flickr last year.

Once they've been identified, the BL will then run the maps through its 
Georeferencer crowd-activity (from which we can download the full 
output).  But first the files need to be identified on Flickr, and 
tagged as maps.

A draft article for this week's en-wiki Signpost can be found under 
development here:

There's also going to be an all-day tagathon session at the British 
Library in London to launch the effort, to which anyone who can make it 
is very welcome.  (Even more welcome if you register first, but that's 
not absolutely essential), see:,_October_2014

There is coverage of maps from all over the world, as shown by this plot 
of 3,000 maps on the globe, that have already been found and georeferenced:

(Non-map images in the collection have a similar distribution).

The BL Labs group are having their annual symposium meeting on Monday 
3rd November.   It would be fantastic, as a demonstration of the power 
of openness, if the lion's share of the index could have been worked 
through by that afternoon.

Make-or-break for that target is whether people can be encouraged to 
help on the internet.

So I would really appreciate anything anyone can do to help get the word 
out -- eg perhaps with mentions in the equivalents of the Signpost in 
other languages.

I'm afraid everything is in English so far, but perhaps there is still 
time to do something about that.

The project status page is here,

which has links to all the geographical index pages, with their pink 
"Untagged maps" templates.

These page will go live at 11:00 UTC on Friday.  (Edits to them before 
then will probably be over-written -- though tags added on Flickr would 
be okay).

I would be really grateful for any help anyone could give with this over 
the weekend, or encourage others to give.  Even an hour, or half an hour 
to go through a block of 15 books in the index, would make a difference.

So anything anyone could do between now and then to get the word out 
would be very very appreciated.

osm-multilingual only in 6 languages?

Around the time of the Toolserver shutdown, WIWOSM started fetching 
tiles from the tile server. But as 
far as I can tell, it only supports de, en, fi, fr, pt, and ru. For 
other languages, it seems to return only a few tiles that had been 
generated before the switchover.

Are there plans to extend this service to the wide range of languages 
supported by the old multilingual tile server? In particular, and the OSM gadget at the Vietnamese Wikipedia both 
make use of the multilingual tiles, but now most Wikipedia articles end 
up showing the default OSM tiles.

graphs, maps, and MW extensions

Per ErikM's suggestion, posting it here. has a preview of the graph extension. The extension is already in production, but will only be enabled for private wikis (zero & fundraising) until we resolve security/privacy concerns (almost done), as well as possible performance implications (node js png rendering)

Graph extension uses vega grammar.

What else needs to be completed for Map Warper, before mass-upload of files and mass usage ?

Hi everybody,

Sorry to have missed the hangout.  I was on the road, then couldn't find 
the correct URL.

Question: what else currently needs to be completed with respect to Map 
Warper, before we can launch a mass-upload of files to it, and try to 
launch a first mass campaign of geo-referencing ?

I asked Tim Waters, who told me he was working on three things, which 
were going well; and recommended I post to this list.

One of the things was letting people log in with their Commons login. 
Unfortunately, I've forgotten the other two, and the email got 
accidentally deleted by mistake.

So what other things do people think need to be altered on the map 
warper, before we
* (a) do a mass upload from Commons to Labs of maps to geo-reference
* (b) launch a campaign for mass-georeferencing the uploads
* (c) use it to display geo-referencing for maps that have already been 
geo-referenced ?

For reference, as an estimate of the scale of what is on Commons already 
(never mind new scans that are being produced), we currently have just 
over 54,000 unique files in Category:Old_maps and Category:Maps_by_year 
together, going down six levels, of which just over 41,000 are in 
sub-directories of Category:Old Maps

There are also
* 4890 maps that we have that already have georeferencing from the NYPL 
(not in the Old Maps hierarchy)
* 315 Ordnance Survey drawings, with georeferencing from the BL (also 
not in the Old Maps hierarchy)
* 1126 maps from the Mechanical Curator collection, of which 107 are 
related to images that have georeferencing from the BL, and the 
remainder should be geo-referenced in the BL's next phase.

(The already geo-referenced maps are or will be accessible in 
subdirectories of
    Category:Maps with links to external georeferencing
-- the BL are there already; I shall be adding the NYPL ones in a couple 
of days, once I have jumped through the required hoops for bot approval).

IMO, it would be nice to get a campaign of geo-referencing underway.

But how close are we to being ready?

All best,
