We want to investigate various ways that maps can be broken and record them. This will be used for future evaluation to decide which might be able to be improved, which might need error messages, etc.
Broken might mean missing information, parts of maps not loading or complete maps not loading. What are the different states, and different problems encountered in each? What are the types of information that can be missing? What does it looks like? If known from this investigation, also note the reasons for things not loading but this can be in follow-up tickets as well.
Different states to investigate (list incomplete, needs thought, just a starting point):
[] Loading (nothing visible)
[] Static maps not loading
[] Dynamic embedded maps
[] Full-screen dynamic maps
[] Tiles not loading
[] Geoshapes not loading (sometimes they load in the small and not the big, sometimes only the full screen but not small)
[] Objects in OSM not visible
[] Editing, preview, final
== Review: Examples
Please add here as you come across more examples. Also check the notes section considering possible solutions.
| Description | Screenshot | Notes |
| Broken | {F35039203} | Should be possible to add an error message. |
| Loading | {F35101431}{F35101444}| The loading displays a broken map stage for a short time: {F35106087} |
| Map tiles missing | {F35101425} | Mostly happens while loading. |
| Map doesn't load, but markers do | {F35101428} | |
| Map not visible in VE | {F35101438}| |
| Geoshapes and markers missing (interactive) | {F35101662}{F35101663} | Should be possible to add an error message. See also {T306987}. May be because the mapdata is missing or unavailable. |
| Geoshape and markers missing (static) | {F35101684}{F35101685} | Should be possible to add an error message. |
| Empty map without an error message for a failed sparql query | {F35102704}| Should be possible to add an error message. |
| Cropped labels | {F35102560} | This is a OSM issue. See also {T228812}. |
| Entire world is repeated twice | {F35129729} | Happens when the map width is larger than the proper aspect ratio. This can also happen when a mapframe is set to automatically choose the bounding box based on a geoshape, but the shape doesn't load. |
