Missing Visual Representation for Node (life_ring)

vcr80 · 2024-07-12T18:04:48.353Z

I don‘t think there‘s anything like „too much information“, especially since one could toggle things on and off. But as far as I’ve seen that’s a feature OSM doesn’t support.

Well, “osm” is just a big pile of data, and you can create whatever maps you like with it (subject to the licence terms). If you look at the link I gave above you’ll see that there are actually 6 layers that can be turned on and off, 2 of which are from OSM data only.

I don‘t fully agree. openstreetmap.org is the somewhat official visualization of that pile of data and should therefore include and visualize all of it.

SomeoneElse:

The fundamental problem here is that any general map style needs to decide what to include and what not to include. That is compounded by OSM carto being limited by the relatively low (by 2024 standards) maximum zoom level of 19. There’s a discussion to be had about whether even at zoom 19 a life ring constitures “clutter”.

Indeed. It’s impossible for one map style to “visualise of all it”. [As far as I can tell, OSM Carto “works” up to zoom 20, but most tile servers are configured to stop at 19.]

I think a 14 x 14 px icon will work at Z19, not least because life rings are spaced out. But you do have to prove that a proposal will work. Most issues get stuck at “Why is my thing not rendered? Please render my thing”, or worse, “This thing hasn’t been rendered for X years. You suck!”.

An interesting question would be whether any vector tile schemas include this data. Going forward, that’s going to be more important than whether OSM Carto shows it.

Shortbread v1.0 doesn’t seem to. I don’t know whether that is being suggested as the “first hosted vector tiles and map styles at osm.org”, but demos of minutely vector tiles have been made using this schema.

I see useful maps goes up to zoom 25. Please add a tape measure, I have not idea of proportions there, is this m, cm, mm?

Hungerburg:

Please add a tape measure

That’s a great idea - if you have any suggestions of how to do that I’m all ears! It’s probably best discussed at https://github.com/SomeoneElseOSM/SomeoneElse-style/ rather than here as it’s not directly related to this help question.

Mapy Cz has length, and area measurement. As well as, aerial imagery, GPX viewing, 3D terrain, and globe view. More functionalities in Czech.

Kovoschiz · 2024-07-14T06:37:18.321Z

While I have my own wishes for Carto, and agree there should be improvements, I see it more as a basemap, besides a rendering benchmark, and editing QA. For raster tiles, an overlay may be more suitable, as seen in OpenRailwayMap, and OpenSeaMap. Then you can show them on any background you want, including with OpenSeaMap, Whitewaters, sports, fishing, AED, fire & rescue, and bathymetry plus waterways or watersheds. The latter can extend to rainfall, flooding, storm surge, wave overtopping, tsunami, etc.

OpenStreetMap Emergency Map

life_ring is also not (yet) displayed, but if you ask @wambacher , I think it is more likely that it will be added than on osm-carto

Not that odd.

I agree, Life-rings are objects which tend to move.

Hungerburg · 2024-07-14T23:10:19.422Z

There is GitHub - ljagis/leaflet-measure: Coordinate, linear, and area measure control for Leaflet maps , but this is stale. Actually, I just wanted usefulmaps to show a scale, because I have no idea what zoom 25 is about!

BTW: In the area of my local knowledge, life-rings are quite stable in location.

Mappy Cz is a commercial, non-open, product. Nothing against that, but promoting it here, particularly without making that clear, would seem to be against the rules of this forum.

Mammi71 · 2024-07-15T08:10:07.364Z

SimonPoole:

es hier zu bewerben, insbesondere ohne dies klarzustellen, scheint gegen die Regeln dieses Forums zu verstoßen.

I’ve never seen that before.
Can you show, link or at least quote the relevant rule?

SimonPoole · 2024-07-15T08:14:25.978Z

Well if we don’t have a rule (written or unwritten) why do we delete spam then?

SomeoneElse · 2024-07-15T08:23:42.846Z

I read that not as a “promotion” but as an idea of what was technically possible.

Mammi71 · 2024-07-15T08:51:20.162Z

SimonPoole:

You’re exaggerating a little.

@SomeoneElse has already formulated it correctly. It was just a hint as to what might be possible.
There wasn’t even a link.

And spam that we delete usually has nothing to do with OSM. After all, MappyCZ makes significant use of OSM data.

Kovoschiz · 2024-07-15T08:59:08.178Z

Spams are irrelevant to a topic, and OSM. How does mentioning an OSM product once in reply to someone in a post violate rules?
In About the Tagging help & support category , I only see Etiquette/Etiquette Guidelines - OpenStreetMap Wiki
According to Category:Proprietary software licenses - OpenStreetMap Wiki , is mentioning the following a act of promotion? Ignoring (paid) games.

Cycle.travel
CycleStreets
Gaia GPS
Guru Maps
Komoot
Magic Earth
Mapbox anything
Maperitive

SimonPoole · 2024-07-15T09:03:45.662Z

Mappy CZ gets promoted a lot in OSM spaces, but it only uses OSM outside of CZ (and doesn’t display specific attribution for those areas that use OSM BTW).

That is perfectly legal (~attribution), but can mislead. I would note that I didn’t report the posting, just felt that it needs pointing out.

Kovoschiz · 2024-07-15T09:05:48.913Z

Ok, fair enough. But there should be clearer rules about that before anyone invokes this risk.
For interest: Recently, I have to mention the Esri product for merging divided roads from OSM, and spatiotemporal join for OHM. It’s unavoidable, not directly available in QGIS. Fortunately I found MobilityDB, that seems to offer the latter in PostGIS.
