Help talk:Extension:Kartographer

Welcome to the Maps discussion. This is a place to provide overall maps feedback.

• Add specific bugs and issues to the Phabricator and tag them with the #Maps tag.
• The existing tasks are here

Previous discussion was archived at Help talk:Extension:Kartographer/Archive 0 and Help talk:Extension:Kartographer/Archive 1.

At w:Claremont Colleges#Colleges, it used to render properly, but checking recently, the southernmost college (Pomona) has only an outline, whereas the others have the fill. Any idea why that's happening?

Pomona is (I think) the only one to have a proper relation on OSM, so that might be part of it, but it shouldn't be an issue as it's still linked from OSM to Wikidata.

Generally, that means the relation on OSM has a hole in the outline and thus fill is not possible

Hmm, I just double-checked, @TheDJ, but neither the relation nor the underlying way has been edited in the past 2 years, and I do not spot any holes.

Why is the relation not shown?

It's apparently a geoline. When I mark it as such it works.

The fact it doesn't work here on the talk page is a fascinating edge-case. As far as I can tell maps with external data just don't work on Flow talk pages because of it's architecture which bypasses pretty much everything other extensions like Kartographer expect.

I hope this helps.

Thanks, that helps a lot! But I guess the parser still has problems with this relation. If I enlarge the map on en:User:Bigbossfarin, the relation disappears. Also changing the color is not possible. One problem could be that the relation consist of many paths.

I included the map in w:Delaware Aqueduct.

Is it possible to set fill-colour (or not fill at all) when showing a .map-files, or are you stuck with the shaded interior?

The .map file can have colors. Here is an example: commons:Data:Bulgaria/149SUSchoolSector.map. Mixing properties when the data source in a .map file is currently not possible. There is an ongoing discussion if this should change, see phab:T323559.

Thanks for the advice!

Tracked in Phabricator
Task T195319

I understand that on the English Wikipedia, the maplink template creates static maps without zoom buttons and without a scale. Would it be possible to add the scale to those static maps? I find scales really important when dealing with maps, for orientation. Cheers, ~~~~

in desktop version you can click on a maplink frame, to get an interactive version. Greetings

Task T195319

Can I add a linear scale to a map?

This is possible in leaflet (the js map library kartographer uses) however as far as I know it is not implemented in the extension.

the examples on the page show coordinates with a precision of 14 digits. This is silly, and uneducational. My proposal is to truncate the example precision to 4 or 5 digits.

Go ahead, it's probably just a result of editing tooling.

Could you please provide an example to draw a geoline based on a OSM way? All of your examples seem to refer to relation objects in OSM, not to ways. I wasn't able to modify the geoline example "Interstate Highway I-696" to work with an OSM way. If this is a technical restriction, it should be mentioned in the docs. Thanks a lot!

Hi, when you zoom in the examples in the "External data" section, you may see that, for example, Alaska is shaded not only on the continent, but also on 20-km range in the sea. What is the reason? It looks wierd when you use this feature to color one province and not the neighbouring provinces.

Ok, I guess the shape from OpenStreetMap is retrieved. I wish it could use https://commons.wikimedia.org/wiki/Data:Alaska.map (although this one seems imperfect).

It's the extend of the administrative area which extends beyond land area. If you zoom in on the west or east coast you will see the same thing.

Ok, thanks!

Hi all

I want to create quite a lot of maps which species distribution on Wikipedia articles e.g https://en.wikipedia.org/wiki/User:John_Cummings/Experiments/Species_distribution_map_multiple

I think I've got a point where I can start creating them on mass but I can't work out if there is a way to automatically scale it to the part of the map that is displaying the shapes. Is this possible?

Thanks very much

By default, it will try to zoom to make all the shapes fit into the viewport. But it is important to NOT specify a zoom factor in order for that to work and no centerpoint either. If your shapes span the entire earth as in your example, then zooming of course also will not work. In fullscreen mode, the zooming seems to assume a square viewport causing parts of the shapes, to sometimes spill out at the top or bottom (someone should probably file a ticket for that). And lastly, if you are in preview mode it also seems to work a bit different (not exactly sure why that is)

Note that TheDJ's descriptions relate to using the maplink template, rather than using a direct call to <mapframe>, with all in geoJSON. Template:maplink is easier to edit, will do the zooming etc for you , and I think will handle the multiple id entries in the way you need.

No I'm not

Task T259868

Are there any plans to allow usage of the extension for 3d arty wikies?

The extension itself is open source. But I guess you would like to use the Wikimedia maps infrastructure. The page for that is Wikimedia Maps and specifically the note about external usage.

Yes, I meant to use Wikimedia Maps )

I just installed the Kartographer extension and it is not working for me. Here is my LocalSettings.php:

wfLoadExtension( 'JsonConfig' );

wfLoadExtension( 'Kartographer' );

$wgKartographerMapServer = 'https://tile.openstreetmap.fr';

$wgKartographerDfltStyle = 'osmfr';

Then I created a test page with just this simple entry:

<mapframe text="San Francisco" width=600 height=600 zoom=10 longitude=-122.3988 latitude=37.8013 />

but the only thing I get is a blank box.
