Module talk:Mapframe/FAQ

Q1: Where to file a bug report when there is a problem with the base map? (e.g. a missing lake)

A1: If the problem also occurs on OpenStreetMap, it needs to be fixed there. If the problem is only on Wikimedia's maps, it can be reported on Phabricator (you can log in with you Wikipedia account). See mw:How to report a bug for instructions (for the tags, use Maps). (Alternatively, you can try mw:Help talk:Extension:Kartographer)

Q2: Where to report other bugs or problems with the maps?

A2: This may be a problem with the Wikipedia module, or it may be an underlying software bug (there are lots of those).

• If the problem also occurs when using plain <mapframe>...</mapframe> tags, then it should be reported on Phabricator (you can log in with you Wikipedia account). See mw:How to report a bug for instructions (for the tags, use Maps). (Alternatively, you can try mw:Help talk:Extension:Kartographer)
• If the problem only occurs with Wikipedia's template/module, or you're not sure, report it here. (Alternatively, you can try Wikipedia:Village pump (technical))

Q3: Why does the thumbnail map render as a static image when viewing pages, but is interactive when editing pages?

A3: On Wikipedia, and most wikis other than Wikivoyage, the emdeded thumbnail is a static map, and the full screen map needs to be opened before the map can be zoomed or panned. This is for for performance reasons, and to present some content if javascript is disabled, and for printing.
That preview mode shows an interactive map is a bug, phab:T203863 (and also a performance issue). Further explanation can be found in the comments on phab:T202793.

Q4: Why is a line or shape feature from OpenStreetMap not being shown?

A4: There are several possible causes:

• The feature on OSM needs to be tagged with the Wikidata id, per mw:Help:Extension:Kartographer/OSM. It is not enough to just set (P402) on the Wikidata item.
• Only certain OSM relations (those with type=multipolygon, type=route, type=waterway and type=boundary) can be used, and not others like buildings and public transport master routes. See mw:Help:Extension:Kartographer/OSM#Limitation and phab:T156433.
• It can take 1 or 2 days after tagging on OSM before the data is available here.
• Wikimedia occasionally has problems replicating OSM data (e.g. phab:T218097), or intentionally disables replication due to other problems (e.g. phab:T243609)

Q5: Why are line, shape, or point features are not shown after editing or adding a map, even though they were shown in the page preview?

A5: This is a bug related to generating thumbnail map images. It should fix itself in an hour or two. See phab:T269984 for details.

Q6: A page using mapframe's |raw= parameter is showing error messages of "The time allocated for running scripts has expired." What can be done?

A6: If the amount of raw data to be processed is too large, that timeout message may be shown. You can try moving the raw data to Commons (example) or replacing the mapframe template with the equivalent wikitext using Special:ExpandTemplates (example)
