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.
