Proposal

A  Video wall (also called an LED Wall) is a large digital screen, constructed out of smaller  LED panels. Digital screens are used to show video, film, TV, camera feeds, advertising content, or other digital content. They are especially common at large events, and at events venues like stadiums and outdoor cinemas.

This proposal suggests a new tag, man_made=video_wall, which may be used for any kind of digital screen (not just advertising).

Rationale

There is already a tag for screens used for advertising purposes: advertising=screen, but not for screens used for other purposes.

Tagging

Notes:

Other useful tags to use in combination are support=*, operator=*, height=*, min_height=* (see examples below)

Examples


  1. Technically the screen is hanging off the truss, but is nevertheless sitting at ground level
  2. Keep in mind Good Practice: do not map LED walls set up temporarily for an event

Special Cases


Height

Use the tags height=* and min_height=* to map the height of the screen. See the page min_height=* for a good explanation of how to use tags

Rendering

none proposed.

  • I abstain from voting but have comments I have comments but abstain from voting on this proposal. I believe our proposals should be self contained and not contain references to external sources in the definition (which could change at any time, and will be changed regardless of the requirements of OSM, in this case, wikipedia). I also believe it could be helpful to better explain which kind of features are included and are excluded, e.g. what about https://en.wikipedia.org/wiki/Project_Blinkenlights or https://designiwall.wordpress.com/tag/realitiesunited/ ? Currently I am tending towards voting no because of these shortcomings, but believe you could stop the voting, improve the definition and then restart it --Dieterdreist (talk) 08:21, 23 July 2021 (UTC)
Hi @Dieterdreist:, the two links you provided look very similar to one of the examples on this page, sorry if there is confusion about whether those are valid. What would you like to add to the existing definition? ("A Video wall [...] is a large digital screen, constructed out of smaller LED panels.") --Kylenz (talk) 08:46, 24 July 2021 (UTC)
I would go with a functional description rather than a physical one. The examples I gave are not using LEDs (at least the first 2 blinkenlights used standard halogen lights), and LEDs are not a requirement IMHO, the distinctive feature is that you can show video. It should also be said whether the screen must be generic (be able to show any kind of video) or if specific (custom single purpose) installations able to show only a certain kind of animation, count in. —Dieterdreist (talk) 08:57, 24 July 2021 (UTC)
Hi, yes we should add the word 'typically' ("A Video wall [...] is a large digital screen, typically constructed out of smaller LED panels"). Regarding your second comment: The first sentence of this wiki page is the physical description. The second sentence is the functional description ("Digital screens are used to show video, [...], or other digital content"). I hope this is clear enough? The type of video shown on the screen does not affect whether you can map it or not. We can explicitly add this sentence to the wiki page if you like. --Kylenz (talk) 09:14, 24 July 2021 (UTC)
  • I oppose this proposal I oppose this proposal. A direction-side definition is not suitable to be added to a feature which can be potentially be both-sided. For reference (need to check whether they are made from multiple display panels), there are ~50 = ~6% advertising=screen + sides=2 instances. ---- Kovposch (talk) 08:57, 23 July 2021 (UTC)
Hi @Kovposch:, this proposal follows the same logic as the existing advertising tagging scheme. I think it just needs better explaining: By default the screen is one-sided, this means sides=1 is assumed. By default the front is the left side. If you add sides=2 then it doesn't matter which side is the front since it is two-sided. --Kylenz (talk) 08:46, 24 July 2021 (UTC)
This doesn't feel logically rigorous. The reason behind my extra disagreement is there have been questions about both-sided features when a tag has been defined with a direction-side meaning, as I have read in /Talk:Tag:barrier=guard_rail#Tagging_guard_rails_with_two_"inner"_sides and Talk:Key:kerb#"Double_sided"_kerbs. This is a unnecessary requirement. It would need extra caution in drawing, and be prone to errors. There isn't such definition for advertising=* either. By adding a combination through man_made=video_wall, you would be imposing an extra rule to advertising=screen that may affect all advertising=* features. In using it, editors will have to reverse the direction of existing advertising=screen objects when adding man_made=video_wall. Alternatively, if one wants to specify the face, an extra tag eg side=* could be introduced. ---- Kovposch (talk) 09:35, 24 July 2021 (UTC)
To confirm, you think we should just remove the requirement to draw it with the left side being the front? I'm not too concerned about that, although it should be noted that this will make things harder for 3D rendering software. I imagine one day someone will introduce a tag like facing=left/right/both for screens, crash barriers, etc. --Kylenz (talk) 09:49, 24 July 2021 (UTC)

  • I approve this proposal I approve this proposal. I do not think a video wall fits the definition of barrier=wall, but that isn't enough to make me reject an otherwise solid proposal. --Tordanik 16:45, 24 July 2021 (UTC)
