Those tags are for things that are still there, if what remains is still 
identifiable as a building/railway/road/bridge then that should be 
mapped in OSM.



Historic things should be mapped into OHM, even if they are no longer 
there or still remain ( a start and end date are usefull in OHM as a 
date slider can be used to revel what is there at that date).

Advise them to enter the historic railway into OHM ... or any
historic object for that matter. This satisfies them that the
object is mapped and frees OSM from it.

(1) sorry for an empty email send earlier

(2) we have plenty of things that should not be added
https://taginfo.openstreetmap.org/keys/mapper - single paid
 mapping group produced 800 000+ instances of an unwanted tag
(they promised recently to fix it)

(3) sometimes this tags are used to describe still existing remains
that is OK, though I would tag it differently
(map existing embankment rather that railway that used to
be located on still existing embankment)

(4) Wiki documents used tags, not just desirable ones
In some cases it documents tags as a very bad idea.

(5) Some people thought/think that mapping completely
gone objects in OSM is OK. AFAIK they used to be more
prominent in the past.

Re: [OSM-talk] CyclOSM Lite a new cycling infrastructure map layer

2020-05-26 Thread Florimond Berthoux
The concept is understood outside Germany and actually rendered in CyclOSM
It's more or less the same concept as cyclestreet=yes, we render it the
same way.
https://wiki.openstreetmap.org/wiki/Key:cyclestreet

Example in Netherland
https://www.cyclosm.org/#map=18/51.56239/5.07029/cyclosm
Example in Germany https://www.cyclosm.org/#map=17/49.88046/8.66031/cyclosm

And yes, CyclOSM Lite should render it also.
https://github.com/cyclosm/cyclosm-cartocss-style/issues/380

Bicycle parking will not be rendered, only road infrastructure.

The legend is crafted by hand with sometime much pain ':)

bicycle_road have some limited motor traffic allowed on it, cycleway none or 
extremely limited

on the contrary, it probably matters !
I'm not surprised that a tag that is incomprehensible outside
its country of origin is not rendered by a style that does not
come from its country.
Despite all the explanations, at worst, it should have been
a value in cycleway, for ex cycleway=bicycle_road (or =road ?)

well, tagging reality disagrees, and it is also a different legal construct
than a cycleway here in Germany.

By that logic you could also say we don't need highway=pedestrian as
irrelevant of construction it is just a footway ...

There is, although it is somewhat hidden. It starts with

"In Germany the following tags are implied but they are usually still
tagged:

vehicle=no (all vehicles are prohibited)
bicycle=designated (except bicycles, road is designated for this
vehicle type)"

but at least in my area most of these roads have the extra
"motor_vehicle=yes" from the bottom of the "additional signs" list.

Also legally it is not just "be aware of cyclists" (for that we have
a different sign, white triangle with red outline and a bicycle icon),
it is "this road is primarily for bicycles, in case of conflict, e.g.
if a space is too tight to pass for both at the same time, the motor
vehicle has to stand back", and it also comes with an implicit
max. speed of 30km/h for motor vehicles, among other restrictions ...

While for the "pure" bycicle_road I'd somewhat agree to "these are just
extra wide cycleways", but for those with "motor vehicles allowed"
exception (which is more like the norm in my area) it is really a
different class of road.

But in the end it doesn't even really matter: such rows should be
visible in the overlay, even if simply rendered the same as "normal"
cycleways ...

Maybe.  If it clearly has lanes marked out, I tend to consider this a
cycleway even if there's no sidewalk as it was clearly built for bicycles a
forethought with minimal, if any, consideration for pedestrians in such a
case.

There's no mention of that on the English wiki page. Looks more like a

Greetings.


Recently, a user mapped “razed” railways inside a construction zone 
(link below). These rails had been removed by our local mappers since 
they don’t exist anymore. Using the latest imagery (Maxar), you can 
see the rails have been completely removed from “Project 70”, a $1.2 
billion Denver-area transportation corridor construction project.



I think this mapper has good intentions, but what is the point of 
mapping something that does not exist? Doesn’t this clearly contradict 
the OSM Good Practice wiki in regards the sections, “Verifiability”, 
“Map what's on the ground” and “Don't map historic events and historic 
features”? The last section states, "*Do not map objects if they do 
not exist currently*."



Should we tag (invisible) razed sidewalks? Should we leave (invisible) 
destroyed buildings in place, tag them as razed and then create new 
buildings on top of them?



https://www.openstreetmap.org/edit#map=19/39.78016/-104.94562




Advise them to enter the historic railway into OHM ... or any historic 
object for that matter. This satisfies them that the object is mapped

looking at my area I'm missing highway=bicycle_road being rendered

And in rather unrelated news I'm wondering whether you generated that
