Maximum Kartographer zoom level is now 18. I ask to add zoom level 19 which is state of the art for all modern mapping tools including OSM.
We can deploy this config change once we deploy a new / clean kartotherian / tilerator version.
There is probably also a config update to be done in Kartographer. We'll need someone (collab team) to have a look on that side.
@SBisson to clarify - the last patch https://gerrit.wikimedia.org/r/#/c/409395/ "Add support for zoom level 19 in Kartographer" is included into deployment of wmf.25. The question: I see some inconsistency in displaying zoom controls on maps between testwiki (wmf.25) and enwikivoyage (wmf.24). Both wikis have Extension:Kartographer.
testwiki (wmf.25) does not display the zoom controls:
wmf.24 https://en.wikivoyage.org/wiki/User_talk:Zilant17/Sandbox will display the zoom controls:
I see the zoom controls in betalabs in UI:
@Etonkovidova: testwiki and most of the wikipedias have the "static map frame" configuration with less controls. wikivoyage and mediawiki do not have it so they can show more controls on the maps.
I don't know the history or the rationale for the various kartographer configurations but this difference is deliberate.
For reference, the following configuration variables would have an impact on the user experience:
