[Tagging] How to tag flood prone points and areas?

[Immaculate Mwanja]

Hi there!

In the summer of 2018, we conducted a project called Assets and Threats
mapping

under the Ramani Huria project in Dar es Salaam, Tanzania that aims to make
Dar es Salaam a more flood-resilient city. In this project, we focused on
the assets/amenities in the city that are important to the community and
are at risk of flooding or not.

After collecting all the information, we decided we should upload them in
OSM to be shared with the world since it was a successful project to some
extent. The challenge came when we could not upload these data since there
is no specific tag to use for amenities or AoIs affected by floods, the
only tag that we could find is flood_prone=yes
 but this is mostly
applicable to “roads/ways" that go underwater after heavy rains.

   1. Is there any other tag that can be used for points under flooding
   threat or can we use another tag?
   2. Our initial thought was to create a new tag i.e. asset:risk=yes and
   asset:risk=no or we could overcome this challenge by having one tag that
   is used by the entire OSM community to identify ways, areas, or points
   that are prone to floods


Kind regards,
*Immaculata Mwanja*

some karts do run on full sized auto racing circuits, but kart
specific tracks are generally much smaller in scale.

lots of motorcycle racing on pavement uses the same circuits
as cars. but again, sometimes motorcycles run on narrower
circuits that are unsuitable for auto racing.

i don't have a proposal here, just conveying information.

[Tagging] What sport=* for automobile racing?

[Joseph Eisenberg]

With highway=raceway, the most common tags are sport=motor,
sport=motocross and sport=karting (and even some sport=rc_car for
remote controlled model cars). These are specific types of motorsport,
except for "sport=motor", which can include automobiles, motorcycles
and go-karts, so it's not very specific. There's also some uses of
sport=speedway which is also unclear.

There isn't really a common tag for raceways used specifically for
automobile racing (e.g. NASCAR, Formula One, Drag racing, Rallying,
etc).

There are 5 uses of sport=autocross, 2 of sport=auto, 1 of sport="auto
racing" (with a space).

It would be useful to have a specific tag since automobile racing,
motocross and karting use rather different raceways in most cases.

Perhaps sport=auto_racing would be clear, and generic enough to cover
most types? https://en.wikipedia.org/wiki/Auto_racing

Also, it looks like there are some other types of motorcycle racing,
other than motocross (which is specifically on dirt tracks /
raceways).

Would sport=motorcycle be good for these? It's used 7 times.

Around here those are called poll-barns. They are usually constructed with
utility poles ( or similar ) a roof truss system, and corrugated/galvanized
metal sheets. They cover farm equipment, feed storage, and sometimes
animals.

And that is a pig pen.  But, according to some, also a pig sty.  An
enclosure rather than a building.


This time, I'd go sty, although pen would also be OK.


In common parlance that could be a sty or a pen.  However, I don't think
you'd map it as
building=sty (or even building=pen) because it's not a building.



The one's I've seen in farmyards have had a rudimentary roof in one
corner, with the rest being dirt or mud!


The bit of roof could be building=sty (a bit of a stretch, though).  I'd
be tempted to make it
building=roof.  Especially as that's how somebody might map it if seen
from the road but
no pigs were around at the time.

Don't you mean "pole barns?"

Looking at the tags, it would appear to be an import from the National
Hydrography
Database.  The NHD assigns it an Ftype of ArtificialPath.  That is
explained here:
https://wiki.openstreetmap.org/wiki/National_Hydrography_Dataset#Attribute_to_tag_mapping

I'll leave it to you to figure out the best way of dealing with it,
although I suspect translating
that particular Ftype to waterway=ArtificialPath was an error (possibly a
bulk error from
a bulk import) and it should have been waterway=river, along with a note
saying it's
an NHD artificial path or a source tag saying it came from an NHD
artificial path, or something.

[Tagging] waterway=artificial documentation

[François Lacombe]

Hi all,

I've notice that waterway=artificial is currently used more than 16k times.
https://taginfo.openstreetmap.org/tags/waterway=artificial

This value doesn't appear to be documented, does someone know what is its
real meaning please?
Only this DataItem is availabe :
https://wiki.openstreetmap.org/wiki/Item:Q19211

Efforts has been made to distinguish open flow and pipe flow waterways and
waterway=artificial may fit in both regimes.
It's an occasion to see if a more precise value is missing to cover those
situations.
https://wiki.openstreetmap.org/wiki/Waterways#Artificial_waterways:_pressurised_vs_Open-flow_Waterways
https://wiki.openstreetmap.org/wiki/Key:waterway#Values

Many objects are located in an area in the US, like this one :
https://www.openstreetmap.org/way/46314476
It seems that waterway=river would be more suitable for this one.

All the best

Re: [Tagging] craft=sculpter <> craft=sculptor

[Clifford Snow]

It looks like just a misspelling of sculptor. OR and ER are commonly used
to describe a person or thing doing something.

As far I can see, British English would spell it as sculptor.

Best,
Clifford

I have to admit I couldn't resist and fixed the spelling some of them in
Europe. While checking the objects I noted some artworks that had been
mistagged with the craft key. If you check around your area for these
you'll maybe find similar problems.

I think it's just a misspelling. I'm a native english speaker and I had 
to check which is the correct spelling (“sculptor” FTR ). I suspect 
that's what's happened here.

This is certainly a valid idea for inventing a new tag and it is good 
that you open up discussion early.  Let me take this as an example for 
two things that have in the past been decisive on the broader success 
of tags:

* local verifiability.  The primary definition of your tag is for areas 
in a certain region that are in the cultural tradition of that region 
called a certain way.  You try to list a few verifiable criteria what 
not to use the tag for - but these are one sided criteria.  Because 
natural=wood does not rule out use as pasture (and neither does 
landuse=orchard, which is also used for cork oak plantations), 
landuse=farmland does not rule out the presence of trees or the use as 
pasture and many savannas (for which we have no specific tag at the 
moment) are created by human influence.  A good tag is one where a 
local observer, even a casual one like a traveler quickly coming 
through, can without much difficulty determine locally if the tag 
applies or not.

* generic meaning.  As already mentioned you draft this as a region 
specific tag although agroforestry is a practice that exists in many 
different parts of the world in different forms.  Such tag will either 
stay a local speciality tag without much chance for being interpreted 
by global data users and possibly mirrored by other region specific 
tags with similar but slightly different meaning or it will morph into 
a broad umbrella tag - for example for any kind of 'area with trees 
that does not really qualify as wood/forest'.  Well known examples for 
such tags are natural=fell and landuse=village_green.

There are three potential tagging concepts i could imagine could be 
derived from your idea that would seem more promising in that regard:

* a tag for agroforestry landuse.  This of course would only be locally 
verifiable if there is active agricultural use.  That would only 
qualify those dehesas that are actively used for agriculture as such.  
And it would say very little about the physical appearance and 
ecological characteristics of an area.

* establishing a generic tagging concept for secondary characteristics 
of areas - like use of orchards as pasture, underbrush in a forest or 
scattered trees on a meadow.  This could be quite easily implemented 
using natural:secondary=*, landuse:secondary=* etc.  Dehesas would 
under such scheme be something like

- landuse=farmland + landuse:secondary=orchard
- landuse=meadow + landuse:secondary=orchard
- landuse=orchard + landuse:secondary=meadow

* creating one or more region specific secondary tags for exising 
primary tags like landuse=farmland or landuse=orchard for documenting 
the region specific ecological characteristics of the area.

[Tagging] Feature Proposal - RFC - Dehesa

[Diego Cruz]

Hi everyone,

This is the first time I use this mailing list, so please excuse me if I'm
accidentally ignoring any step in the proceedings.

I have recently proposed a new tag in the Wiki, because none of the
existing landuse tags seem to match it. A dehesa is a type of land that
combines a forest with either fields or pasturelands (or both) at the same
time. It is extensively used in the Iberian Peninsula, both in Spain and
Portugal. Please see the details in my proposal below:

https://wiki.openstreetmap.org/wiki/Proposed_features/Dehesa

Thank you in advance for your contributions
