Description

For ExternalData (geoshape/geoline, or Commons .map page), a mapframe map that doesn't specify coordinates and/or zoom in the tag will not automatically zoom and center the map if static maps are enabled, but will work with interactive maps. Due to T203863, this difference is easily noticeable when comparing a saved page (showing a static map) with a preview, from wikitext edit mode, of that page (showing an interactive map).

Geoshape example

<mapframe text="Furillen markerad med grått i kartan." zoom=11 width="200" height="200" >
{
  "type": "ExternalData",
  "service": "geoshape",
  "ids": "Q1474958"
}
</mapframe>

@jmatazzoni I have no idea what this is (except that I can reproduce the issue). This looks Kartographer related more than Kartotherian / tilerator. Can we prioritize this high (or higher) in the collab team work?

Catrope moved this task from Untriaged to In Development on the Collaboration-Team-Triage (Collab-Team-This-Quarter) board.

It looks like Kartographer is deliberately loading ext.kartographer.staticframe instead of ext.kartographer.frame, but staticframe doesn't seem to work correctly.

I can reproduce this bug locally by setting $wgKartographerStaticMapframe = true; in my config.

That was a red herring, it wasn't working because my test domain isn't whitelisted by the server. In production, static maps do work correctly, but only if the coordinates are specified. The map on the Furillen page doesn't specify the coordinates directly but uses a Wikidata Q-ID, and that doesn't work with static maps. See https://sv.wikipedia.org/wiki/Användare:Roan_Kattouw_(WMF)/Sandbox

It looks like dynamic (i.e. non-static) maps have a feature whereby they automatically center shapes drawn onto them if you don't specify a lat/long, but static maps don't have this feature. If you change zoom=11 to zoom=3 in your example you'll see that the map isn't actually broken, it's just centered on an area in northwest Africa while the shape you're drawing is in Sweden.

It seems to me that specifying a map using only a Wikidata ID without setting lat/long, like the Furillen page does, is fundamentally incompatible with static maps (unless we do a fair amount of server-side work), and I don't see how it could ever have worked. Maybe other uses of this tag do specify lat/long? Was the way svwiki uses these tags changed recently?

To clarify: the Furillen page should work just fine if you specify lat/long.

Turns out this is not actually a duple of T155927. That bug is about maps with Wikidata usage in external .map pages, while this bug is about static maps not centering themselves in the right place when using a Wikidata ID. It is, however, related to T178321: Template: Maplink — add ability to use lat/lng or Wikidata Qid for a point .

T158919 seems to be related. Will that task also solve this task here?'

Edit: Indeed, above examples work now that patch from T158919 is deployed.
Thanks for figuring this out!
