Re: [Tagging] Road barrier

[Paul Johnson]

Most data consumers seem to treat barrier=* as access=no by default; it's a
good idea with barriers to explicitly tag for access on barriers.

This sign doesn't block mofa. I tag this as : motorcar=no motorcycle=no

Depending of your country, rules may be different ( some use 
motor_vehicle=no mofa=yes )

but no need to add bicyle foot =yes, all is allowed by default

I have tagged this sort of thing as a (fancy sort of) bollard. That was
at the suggestion of another mapper in my local area.

[Tagging] Road barrier

[Selfish Seahorse]

Hi

How is this kind of road barrier that prevents access for motor
vehicles but allows pedestrians and cyclists to pass on both sides
best tagged?



Is barrier = yes (+ bicycle = yes + foot = yes + motor_vehicle = no)
enough information for routing engines?

Thanks and have a nice weekend

Thank you, Ralph.
If you look down below (as people started to write bottom up in the XXth
century) you will see that I found Projet de canal Meuse et Moselle

(Genglish
),
seeming to confirm what I wrote: that talus is the remnants of that old
canal, commonly called "canal de l'Ourthe", washed away by the frequent
flooding of the Ourthe and of various fate along its course.
So, what I should normally do is map a canal.
But as nobody ever saw a canal with a single bank looking like a talus,
that would get me in troubles.  Not counting that the rendering, even if
we cannot tag "for" it, would try to fill it with water and cause even
more flooding ;-)

So, good-bye canal, what it has now become is a crumbled bank, a
crumbled wall I suppose..

That is just as queer, so, unless you change your mind, I'll tag it man
made=embankment
,
according to your repeated consent, but only as a single way at the top
of the slope I suppose.
But I'll name it an old canal's bank.

Thanks to all,
Cheers,

André.

Re: [Tagging] opening_hours for public transport routes?

Is it common practice to represent the starts/ends of public transport 
route schedules with the opening_hours tag? For example, Red Rose 
Transit Route 1 in Lancaster, PA uses this 
 
schedule. The leg going out to Park City Mall only starts on weekdays at 
6:50; in the 45 mins before then, the bus just turns around on a 
different street back toward downtown. I would guess that the best way 
to map this would be have two route variants with the appropriate 
opening_hours tag, which are united by a route_master relation.


I don't think OSM is the place to map transport timetables and thus 
opening hours.


Unless you mean the physical opening/closing hours of stations which can 
be closed off to the public (locked gate etc), but opening_hours 
shouldn't be put on a route relation. The opening_hour will be wholly 
different for the start and the end of the line (for longer lines, there 
can be 1.5 hour between start and end!)

Re: [Tagging] [OSM-talk-be] how to map a fr:talus?

[ralph.aytoun]

I have had a look on the Wallonia website. If you zoom out you will see that 
this feature runs exactly parallel to the road to the south of it. It is man 
made. It would have been created at the same time as the road. It was done to 
raise the road to a higher level as a flood defence against the river to the 
north. I do not know but it may be that there is a retaining structure of stone 
or concrete to strengthen it but is covered with soil and grass.

The tag for this could be man_made=dyke with material=soil.

You will see that the farmland to the south of the road has something similar. 
This is not flood defence, it is terraced farming to stop the run off of water 
on sloping farmland.

The tag for this could be barrier=retaining_wall with material=stone/soil (or 
whatever material is used)
Hope this has been helpful.

Ralph

Hi,

I'm looking for how to map what is called in French a talus (Google's 
translation).
I would call this a 1.8m simple step running for some reason for several 100s 
meters across meadows.
Steep slope. There are "top of slope" and "bottom of slope" lines. Rest is 
perfectly flat either side.
It might be the remnants of a old canal's bank whose other side would have been 
eroded by the often overflowing nearby river.
A "talus" made of plain ground is often frequent at one side of a path or track.
According to the wiki, it's not a "scree" nor a "shingle". It's much less 
matter specific.
So what?
I'll use "scree" unless/until I hear of better for a French talus.

Cheers 
André.
I'm not entirely sure this is what you have in mind, but in the cases where it 
is associated with roads, I've seen historic=hollow_way (when the slope is 
caused by the fact that there's an old road), and "embankment" or "cutting" 
when the slope is deliberatly constructed. In other cases, I've seen what I 
think you describe mapped as natural=cliff, which is obviously wrong, but does 
get the message accross. For example where sand or rock was quarried this is 
common to see on the map. I'm hoping someone has seen better ideas.
Thanks for all your fast answers from which I had to choose the first one to

A photo was asked. I might go back there to make one, but you wouldn't see more

It can be seen on this map share, pan it to the left and right.
The two striped, faint lines are the upper and lower edges (rims, levels) from 
the BE SPW(allonie) PICC numerical imagery (JOSM) overlay allowing me to map 
it. As you zoom out, you will see that the aerial photo is darker along that 
line.
The Cartoweb background (Fond de Plan) draws it as the typical "behind which to 
hide" line of old military maps.
Well, in OSM parlance, it's not a cree because there is no cliff (1), not a 
shingle because there is no sea and not an embankment because there is no road 
to be an attribute of.
Well, as I said it, what I'm facing seems to be, as I found more specifically, 
the remnants of this old canal @ N°12. The river often overflows as high as 
above the road. When the water goes back, it washes the left bank of the canal 
towards the river but the right bank is mostly just overflown.

So, there's nothing in OSM for that precisely.
Would man_made=dyke be the most resembling and acceptable with an explanation 
note?

Thanks and TIA,
Cheers 
André.
(1) there's a very beautiful one, but at the other side of the river, called 
"La Roche aux Faucons" (Falcons' Cliff).
