Task T362531

The 'OSM Location map' template, previously using the Graph: extension, has now been converted to get the maps from <mapframe>. One loss from this is the option for a basemap with no names. In Graph this was possible (and quite widely used) by setting 'style=osm' rather than 'style=osm-intl'.

The relevant phrase from the Kartographer installation page says:

$wgKartographerStyles

["osm-intl", "osm"]

Available map styles users can request from your $wgKartographerMapServer via mapstyle="…".

But as I understand it, this has not been made available to <mapframe>. If there is any way this could be given as an option, it would help the various editors who are asking for this at en:template:OSM Location map. Thanks.

Technically, mapstyle="osm" is available. However, I think I discovered a bug that might explain the confusion, see phab:T362531. Can you tell on which wiki you are experiencing issues with this?

It is on En:wikipedia. Having just tried it, I find it does indeed work, but not in preview. When trying different combinations, it had not occurred to me to submit any of the edits, when it didn't preview as working. That is a really useful step forward. If the bug can also be resolved, that would be even better. Thanks

Great, that confirms the issue I have seen. Thanks! The fix should be deployed the next days.

Great news. At risk of pushing our luck ... an editor also mentioned how street names continue to be shown at zooms 14 and upwards, even with the labels supressed. Just in case there was a simple way to remove them as well, I said I would mention it here. Thanks

Whenever I am in VisualEditor and try to click on the map button to add one, it pops up with the window but constantly is loading and doesn't try to show a map. I can't click neither the exit nor save button, but if I press esc then it will let me exit out with nothing. I am on MediaWiki 1.40

> I am on MediaWiki 1.40

So not a wikimedia wiki ?

Yes sorry I tried using it on MediaWiki thinking I could use it like any other extension. But I guess I will have to try to use Maps

How could I draw a circle using Kartographer? This would be useful in describing a radius of action or an operating range.

Kartographer is based on GeoJSON and can only offer what GeoJSON supports. What you can do is to draw a polygon that looks like a circle.

Good day, am I able to use Kartographer on my own personal Mediawiki installation? Thank you.

If you also bring your own map tile renderer. in theory. yes. But that's a pretty theoretical answer. In general for 3rd parties Extension:Maps is a better option.

Thanks TheDJ, experimenting with Maps now, appreciate your feedback.

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!

Probably a too late answer, but OSM cannot identify entities other than relations, in a stable way. Anyone is free to move/replace/split/combine ways "as they like". OTOH, editors usually keep relations in place...

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!

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

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.
