 * Using Wikimedia credentials on an external site would be best done by Wikimedia being an openid provider, or as a distant second option, supporting it in omniauth Pnorman (talk) 03:36, 25 September 2015 (UTC)

WM IT

 * I brought this to the attention of WM IT, which at some point will also become the Italian chapter for OSM, thanks to the efforts of User:Cortesi and others. HTH, --Elitre (WMF) (talk) 16:38, 26 August 2015 (UTC)

Controversial borders
Hi,

I noticed some controversial borders at https://maps.wikimedia.org :
 * The border between Crimea and Kherson is shown as international, which is the Russian Federation POV.
 * South Ossetia and Abkhazia are shown as countries, which is the Russian Federation POV.
 * The border of Kosovo looks like a border of an independent country (Kosovan POV), but it doesn't have a country name (weird POV ;) ).
 * As a technically opposite example, there's no border in the middle of Cyprus (Greek POV), but there is a label for the Turkish Republic of Northern Cyprus (Turkish POV).
 * The border between Israel and Syria is shown according to the Israeli POV.

There are possibly more issues of this kind.

Wikipedias usually show maps of disputed territories quite well. For example, maps of Russia and Ukraine usually show Crimea in a special color - even in the Russian Wikipedia.

I understand that at the moment Wikimedia's maps service probably just takes whatever OSM provides, but ideally it should do something similar to what the Wikipedias do and be as neutral as possible.

(I tried to be as neutral as I could in this post ;) ) --Amir E. Aharoni (talk) 19:39, 17 September 2015 (UTC)
 * There is no neutral way to display map borders. Not making a choice is inherently taking a side --Guerillero (talk) 01:10, 18 September 2015 (UTC)
 * Exactly - indicating a border is disputed is taking a point of view, just like representing a border as not disputed is. Countries often do not agree on if an area is disputed or not. Pnorman (talk) 08:17, 25 September 2015 (UTC)
 * Thanks ! Filed as T113008. Indeed this does not look very NPOV. The data comes directly from OSM, so we should ultimately work with the OSM community to solve this (unless it is already present in the data with some extra flags that we should look at and draw accordingly). Also, if OSM community chooses to follow a different route, we might have to introduce a separate database of such cases and allow community to edit it. Obviously I would much rather have it fixed in OSM (if it is indeed broken there).  --Yurik (talk) 01:14, 18 September 2015 (UTC)
 * Thank you Yurik. Sounds sensible. --Amir E. Aharoni (talk) 08:19, 18 September 2015 (UTC)
 * OSM usually follows an "on the ground" POV about borders. Areas are not shown in the countries they "should" be or they rightfully belong -according to any given criteria- but they show which state de facto governs the territory. It's a simple approach that fits initial OSM goal -to provide road maps to travel using a GPS- but it couldn't be the better approach for an encyclopedia.--Pere prlpz (talk) 18:48, 21 September 2015 (UTC)
 * The OSMF policy on disputed territories is best explained at http://wiki.osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf. Crimea is a bit of a unique case as it is mapped as being in both Ukraine and Russia, as per http://wiki.osmfoundation.org/wiki/Working_Group_Minutes/DWG_2014-06-05_Special_Crimea.

How to submit patches?
It's a bit unclear from the page, but it looks like https://maps.wikimedia.org/ is run by kartotherian? I've whipped up a provisional patch for hi-dpi/retina display support but can't submit it via 'git review' as there's no .gitreview in the repo. --Brion Vibber (WMF) (talk) 20:31, 17 September 2015 (UTC)
 * It's all in GitHub. Also, the index.html you're probably trying to edit is just an example, we're not intending it to ever be a full-featured map:) Max Semenik (talk) 20:35, 17 September 2015 (UTC)

Missing fonts
It seems the map server is missing some fonts to render characters of place names in what I think is Georgia: https://maps.wikimedia.org/#9/41.8297/44.2474 —Galaktos (talk) 21:39, 17 September 2015 (UTC)
 * Its a Unicode bug in Mapnik, tracked by T108846. --Yurik (talk) 21:52, 17 September 2015 (UTC)
 * Alright, thanks. —Galaktos (talk) 22:09, 17 September 2015 (UTC)
 * Other case here If you zoom out, the entire name of the city is shown. Sturm (talk) 11:00, 23 September 2015 (UTC)

Geopedia
(HTML 5 / mobile and desktop)

I developed a tool called Geopedia (http://www.geopedia.de), where I could add your map too. Currently I use leaflet and the DE open street map, as I use it primarly for travelling and wanted to have latin city names... I could also add your maps through a layer selection in the settings. Let me know what you think - also very open for further ideas and improvments..

KML
Will we be able to overlay KML layers onto the map? i.e. will we be able to include links in w:en:Template:Attached KML and w:en:Template:GeoGroup (and similar templates on other language wikipedias or other projects)? Current uses are, for example: - Evad37 (talk) 04:01, 22 September 2015 (UTC)
 * Interstate 96: Route map links at top-right of page, and in box at bottom of page, from
 * Circle line (London Underground): Map all coordinates links in box at bottom of page, from )


 * Overlaying a KML layer would generally be done by the map library, (e.g. leaflet), and there would be no problems doing so with these tiles. Pnorman (talk) 23:38, 24 September 2015 (UTC)

/style/z/x/y.png format doesn't work!
says
 * https://maps.wikimedia.org/{style}/{z}/{x}/{y}.{format}

but this doesn't work and returns 404 "Cannot GET /osm-intl/7/43.66/4.719.png ", e.g.
 * https://maps.wikimedia.org/osm-intl/7/43.66/4.719.png

If I go to maps.wikimedia.org and pan around, it only updates the URL fragment without any  or path at all, e.g.
 * https://maps.wikimedia.org/#7/43.66/4.719

?? -- SPage (WMF) (talk) 02:04, 23 September 2015 (UTC)


 * {z}, {x}, and {y} are the standard slippy map tilenames, not latitude and longitude. http://wiki.openstreetmap.org/wiki/Slippy_map_tilenames has more information, including example code for converting.
 * The page at https://maps.wikimedia.org/ is a preview page to display the map, not the map tiles themselves Pnorman (talk) 23:36, 24 September 2015 (UTC)

Isometric projection
When I went to last Wikimania I could talk to some WMF developers, specially to Yuri, about this question (during the OSM workshops), and sorry if this not the proper place to discuss / ask for it. But, here we go! ;) Despite the main OSM visualization, there is also a isometric projection (take a look here also) implemented by the OSM Buildings website. How difficult is to offer such visualization on Maps Wikimedia? Sturm (talk) 11:09, 23 September 2015 (UTC)
 * Another very interesting "3D OSM data converter" is the OSM2World, a converter that creates three-dimensional models of the world from OpenStreetMap data. It is published as open source (LGPL). Sturm (talk) 18:27, 29 September 2015 (UTC)

Marble KDE
I find that Marble, a virtual globe application (totally open source, years of development under KDE Educational programs) which allows the user to display many planets and satellites as a 3-D model, could be a great joint venture to the Maps Wikimedia project. They have a large list of public domain and CC maps applied to it, as you may see here and they also have an app running beta, take a look here. Sturm (talk) 11:20, 23 September 2015 (UTC)
 * During last Summer of Code (GSoC), they made significant improvements in OpenStreetMap vector rendering, for example. Sturm (talk) 11:23, 23 September 2015 (UTC)

Documentation
I know that Maps Wikimedia is still a very starting project, but it would be very useful to see some version informations, release dates, changelogs, roadmaps etc. It helps a lot to understand about the project and help it. Regards, Sturm (talk) 13:08, 23 September 2015 (UTC)

Style improvements
The map style is already nice for an basemap :-) I noticed some small issues that might be worth to get fixed: Maybe somebody can see if this makes sense --MyRobotron (talk) 16:18, 24 September 2015 (UTC)
 * Area highways missing https://maps.wikimedia.org/#18/54.08876/12.13958

Requested feedback
User Feedback for UK looking for details in. Using Firefox on Linux

1. Map opens on the wrong continent- not on the location of the last article I saved.

2. Zoom level 7- the town names given are weird. Liverpool- but not Manchester, Sunderland but not Newcastle-upon-Tyne which is a factor of 10 bigger

3. Zoom level 8- the town names seem to relate to cathedrals not centres of administration or population. Canterbury (55,000)but not Maidstone (113,137). Greenwich Bromley Ipswich all missing. But we have St Asaphs with a population of 3,355. (no that isn't a typo!)

4. Level 9. Names are truncated- Barnoldwick has become Barnoldswi moving south we have Whitworth|Whitwor, then Bollington|Bolling and Macclesfield|sfield. b 5 Level 12 appears OK but level 13 its back again. In level 13 we have a new set of names- that seem

6. The one thing we need from a map is the ability to place a cursor over a spot and see its lat/long geotag- like [.[Co-ord|53.7028|-2.3806|display= title, inline]] Then to copy this to the clip board with a right click- sadly this shows https://maps.wikimedia.org/osm-intl/10/504/329.png not 53.7028/-2.3806. Extracting this from the url doesn't help as there is no indication whether this centre, top left or what

7. How do I turn off selected layers?

8. How do I access the layer showing location of Wikipedia articles? ...commons images? ...wikidata?

I look forward to watching this project develop--ClemRutter (talk) 23:36, 25 September 2015 (UTC)

Project goals?
Longtime Wikipedian and OpenStreetMap contributor (and data reuser) here. It would be great to have a summary on this page about the actual project goals. Is it really just to produce another source of OSM-derived map tiles? Presumably there is some reason that OSM's own tiles, or another provider like MapBox or CartoDB could not be used - could this be explained? Is there something special that WMF wants to bring to the cartography? Novel sources of data? Different hosting requirements?

I'm probably not the only wondering why exactly WMF needs its own tile server, and how this helps "our knowledge engine ... to be powered by multiple entry points". Stevage (talk) 13:54, 27 September 2015 (UTC)


 * Stevage, I am not a member of the Discovery team, so I cannot speak on behalf of it, but I think the immediate needs were to integrate OSM easily with Wikimedia sites without creating a huge tax on OpenStreetMap servers. I do not know if that is the case anymore, but I remember at some point OSM administrators asking to ease the load from some Wikipedia functionality. Having our own tile and static image servers will allow, with enough resources, support both the huge traffic that Wikimedia sites have, and -at the same time-, not sending traffic from our users to 3rd party sites, some of them commercially driven and with privacy rules potentially not so strict than ours (anonymous, not sharing, short data rentention).
 * I know that there is a desire to also bring additional features not present on simple image tile servers (I heard about vector tiles). But you should ask about those directly to Yurik. But if it would only help to have an OSM map on every wikipedia page (not possible before), it will be positive for both Wikimedia content and OSM visibility. --JCrespo (WMF) (talk) 14:58, 27 September 2015 (UTC)
 * Regarding OSM's own tiles, see http://wiki.openstreetmap.org/wiki/Tile.openstreetmap.org/Usage_policy and https://switch2osm.org/using-tiles/ - they make it quite clear that they don't want people to use their tiles directly. - Nikki (talk) 15:45, 15 October 2015 (UTC)

Proposed IEG project
I've proposed an Individual Engagement Grant project to do some work on the maps style: https://meta.wikimedia.org/wiki/Grants:IEG/Wikimedia_Maps_Rendering_Improvements

I'm proposing working on road labels and borders. I'm not proposing to work on place labels as part of the IEG, because I had trouble defining good acceptance criteria. I didn't want an open-ended project where I'd have a hard time calling it done. Pnorman (talk) 19:34, 29 September 2015 (UTC)

Coordinate tagging
I think one of the simplest easiest things that we could do with the new server is tagging coordinates of photos in Commons, and tagging coordinates of articles in wikipedia. We could have a coordinate TemplateData field and hook up a dedicated editor to that. Would be awesome, relatively simple to do, and not put too much load at once on the servers. —Th e DJ (Not WMF) (talk • contribs) 09:28, 10 November 2015 (UTC)

Uniform coordinates across projects
This has very little with tiles to do, but I think this is essential. There should be a recommended, documented and tooled way of creating geodata that will be reflected in all Wikimedia projects. In my humble opinion the point or line or area for the topic of a Wikipedia article should be expressed in OSM, the data should be reflected in Wikidata (through tagging in OSM), from where the data should be displayed in all Wikipedias. A related topic is where to store the geodata that is not current street map data: historical street map (for which OpenHistoricalMap project is targeted) or thematic data (for which there is no solution). --Susannaanas (talk) 18:32, 10 November 2015 (UTC)
