Need to add some `usage=*` values to the `type` key in the vector tiles

[1ec5]

Andrew S. reports on the forum that the more prominent rail rendering only applies to railways that are incorrectly tagged as having a name of usage=main. The following legacy filter and five others like it should be rewritten to compare usage to main, not name to usage=main:

The work-in-progress rail style is also affected:

Thank you! Will work on this this week

I do not see "usage" in v tiles attributes

[vknoppkewetzel]

Checking v tiles itself

I know that we have discussed wanting another attribute added on so that we dont use name=usage=main

---

What I do see here is that industrial is name=industrial which is different than the other rails name=usage=XYZ in OHM vtiles

[vknoppkewetzel]

This may be a case where OpenSTREETMap has the data as usage=main but it doesn't exist in OHM tiles (yet)

[vknoppkewetzel]

The tag usage=main is the correct way to designate main train lines. However the correct rendering of the main line with more prominent features only seems to work when the tag ‘name=usage=main’ is also included.

Example, the only difference in tagging between the two lines shown here (at top left) at OpenHistoricalMap 1 is the presence of the name tag:

Tagging: name=usage=main railway=rail usage=main

---

The second rail is not showing up as main because it is not tagged as usage=name=main, It has no name tag at all so it only shows up in class=railyway and/or type=rail

[vknoppkewetzel]

I can be reassigned when vtiles are updated to include usage - flagging this ticket is an example of updating vtiles. On Wednesday we can chat about whom best to tag to do that work on the devseed side?

Ah, that makes sense. I’ve been wondering when we added usage to the tiles that the style was even considering it already.

[vknoppkewetzel]

Last week in OHM carto meeting we chatted and noted that in some cases, we can grab usage via type in the interim.

I can flag in this ticket which railways allow for that. This is an interim solution, as a path forward, we would either: 1) create a new attribute called "usage" in the data or 2) make sure usage is captured outside of the name=... and place usage into the type category. a minor issue here is that type=rail for some data, but perhaps that doesn't matter as class=railway, so type=rail is likely redundant.

Option 2 seems like a good path forward. type=rail honestly is redundant, as class=railway

Using testbed as reference

---

main branch industrial military tourism spur (service=spur --> this already is how data is styled) siding (service=siding --> already how data is styled) rail (as catch all category - ie "what is classified as railway + rail but doesn't have other category") tram (already classified as type=tram light_rail (styled as part of general rail category) subway (type=subway, already styled as such) narrow_gauge (type=narrow_gauge, styled in rail mini layer) miniature (type=miniature, styled in rail mini layer) monorail (type=monorail, styled in road_rail_tram) funicular (type=funicular, style in road_rail_tram) rail construction (type=construction, styled in roads_rail_construction) proposed (type=proposed, style in roads_rail_construction) disused (type=disused --> roads_rail_old) abandoned (type=abandoned --> roads_rail_old) razed (type=raized --> road_rail_old) preserved (type=preserved, in roads_rail layer)

[vknoppkewetzel]

Confirming it is the following that need to have their type replaced with the below:

• main
• branch
• industrial
• tourism
• military

and ideally we remove rail from type=rail in the data. class=railway already captures rail

@danrademacher - who's the right person to task with updating whatever files need to be modified? (config.toml?)

[jeffreyameyer]

@1ec5 - I renamed this ticket - please double-check that I haven't mischaracterized the ask.

[1ec5]

That’s accurate – this is a top community request for a hopefully straightforward change to the TOML file.

I found only 10 objects that has usage attribute, and I've added the usage attribute in Vtiles - staging. https://vtiles-staging.openhistoricalmap.org/#18.13/-32.93544/151.720113

[Rub21]

These are the objects that have the = character in their names. This can be fixed by manually adding the usage attribute to the names.	ID	Type	Name

198794315	rail	service=spur

usage attributes has been added to production, https://vtiles.openhistoricalmap.org/#18.13/-32.93544/151.720113!!
