André, i don't really see your point with the argument you made about

When tracing buildings, we should always base our self on the PICC for 
Wallonia or Urbis for Brussels or GRB for Flanders and the relevant 
best imagery in each case (comparing them keeping in mind that 
vectorial data are not up to date everywhere at the same time).

Lionel,

I'm not sure what you read because what you say is exactly what I wrote:

But there is a *BIG WARNING*.*
*PLEASE *DO NOT* use the [Cadastre] WMS to trace, and I suppose that 
the import data exhibits the same problem.

..
For what I have seen of it in Wallonia, the Cadastre WMS map usually 
exhibits an error shift (wrong coordinates) as large as 10m and the 
houses and other elements have a wrong shape and location within the 
parcel.

See example below.
Instead, use JOSM with PICC in Wallonia and AGIV in Flanders.

The Cadastral map can be useful to:

  * find a house number not displayed on other maps
  * find a house not displayed on other maps, but do not rely on the
house location (latlon)
  * trace boundaries, especially former municipalities', but be aware
that Cadastre's boundaries are slightly different from other
sources, in particular because they avoid crossing a parcel. They
are official.
  * use names not displayed on other maps and in particular a very
nice set of locality names
  * maybe use other features not needing a precise location

So, the usage of the cadastre is limited to displaying a JOSM layer, 
just for comparison with the PICC, aerial or other maps.

Even more than tracing, beware of importing cadastral data !
PLEASE DO NOT destroy with cadastre imports patient corrections with 
JOSM and PICC of ID and Potlatch inaccuracies and mistakes !!!

What's the problem?
I'm glad that we totally agree.

About what you write below, if you have contacts with PICC (SPW don't 
always reply)...
You don't define ICAR (not free) but I seem to recall that there is a 
free list of street names.

Could you ask them to specify the coordinates of both ends in this list?
I think that the list is freely usable and those coordinates would allow 
OSM to at last start mapping roads correctly.


Also, PICC welcome corrective remarks but they don't say how to do that 
and they ... don't reply.

I have quite a number of corrections I didn't send because of that.
I suggested reviving OpenStreetBugs or equivalent for OSM to notify bugs 
to PICC ... or equivalent ... no answer.

Support in JOSM would be nice.

All the best,

André.


To quote a report from the last PICC meeting in June, wallonia have 
the following idea on official source :


Wallonia is planning a “*georeferentiel*” (base of layers that are
high accuracy and authentic source) within the application of
INSPIRE.There are 4 major datasets that will be made as accurate
as possible and with one authentic source for each:

  * /buildings/ (in PICC),

  * /admin limits/ (in cadastre),

  * /addresses/ (in ICAR) and

  * /Roads/ (in PICC/”direction des routes” collaboration with
attributes (like primary, secondary, highway, bridge,…) on
road, not only geometry).

from: 
https://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Contacts_with_local_autorities/Wallonia/Compte_rendu_Rencontre_des_utilisateurs_du_PICC_Juin_2018


So cadastre is really about admin. limits and parcels :
- For admin. limits i already talked about it before (as quoted, it is 
even the authentic source for all Belgium apparently),
- and for parcels, there is an open debate about adding this 
information to OSM (mainly because it is huge amount of work to 
maintain it) -> as discussed on the wiki page 
https://wiki.openstreetmap.org/wiki/Parcel


So there is no ambiguity in what official data exist, the only problem 
is that ICAR for the addresses is not yet finished for all 
municipalities (and not complete in the PICC as far as i know ?! but i 
may be wrong about that) and more importantly, it is not open nor 
viewable except for special customers. So we still need to rely on 
tracing from the imagery and the PICC WMS at the moment (for 
buildings, roads and addresses) and now, the Cadastre data (or wms) to 
maybe update admin limits.
Note that these official data are considerably improving over time ! 
They are still outdated or imprecise in some place, but even then it 
is still the official source at the moment (so we should NOT copy 
blindly as you said, but compare with recent imagery and survey !!!). 
The plan is to make an update cycle

Ok .. thinking on it, if the word 'sewer' is confusing for 'native'
English speakers (and dictionaries) it may be best avoided within OSM.
So what word/s to use?
I would think storm_water and waste_water or stormwater and wastewater
might be reasonable values? However that does not name the pipe function.

Perhaps man_made=pipe would do? Then subtags for diameter, substance,
pressure etc.


We already have man_made=pipeline
It is only the nutshell, how the conduit is actually built, not what's
going inside. Substance=water is recommended and useful but not enough to
qualify the flow.
A pipeline may be opposed to tunnel. In the current situation it's
certainly a pipeline and not a tunnel.

I don't think "pipeline" is appropriate here.  My reasoning is the same 
that Martin Koppenhoefer expressed recently in another thread titled 
"Landuse for government offices?"  He said, "A lot of people have an 
adversity to making up new tags and prefer using established tags even 
if the meaning is not fitting perfectly for the thing they map, but this 
is harmful because it devalues/blurs the meaning of the established 
tag."  I think that fits here.  What I
 mean is, I think most people think of a pipeline as being 
pressurized.  If you include something under this heading that is not 
pressurized, I think it blurs the meaning of the tag "pipeline".  I 
think in this case a different tag is warranted.  If "sewer" is 
confusing, I like Warin's suggestion of man_made=pipe.

how did you know which source was off, the cadastral map or the

the abutters tag has a different definition, it isn’t intended for the purpose 
of mapping the context according to traffic law classification. I would not 
start using this established tag differently.

My proposition for the purpose of maxspeed would be using source:maxspeed = 
country/state code:residence or business, unless signposted of course.

everything that you map will be according to your understanding of it, I cannot 
see a good argument for not tagging implicit limits, even more as there is 
judgement needed based on the situation (something humans can do much better 
than computers). Every holder of a driving license should have the requisites 
to recognize the speed limit on a given piece of road in their local area, so 
it doesn’t require specialist knowledge.

We already have a reliable way to distinguish implicit from explicit limits (we 
even have several of them), if you want to treat them differently in your app, 
you can do it.

There actually is a speed limit on most roads, including those without explicit 
signage. Omitting it will leave us in the situation that it really becomes 
unclear whether there is no sign or nobody has bothered to enter it.

Some are in the open, possibly a car park - away from the building where the

Some 'multi purpose' assembly points would also be used for bomb threats.
For bomb threats the location should not be known nor regular as the bomb could 
be placed within the assembly point to cause maximum devastation.
This kind should not be mapped.




Tsunami (height in M)

Fire
Landslide
Flood (out of the path of a possible dam breach, levee break, or flash floods.
Tornado (assumed no, yes has to be explicit)

With certian assembly points, the idea it is "safe" from a tsunami is very 
important. Tornadoes will be basements/bunkers/buried shelters, possibly fallout shelters.

But this would be a very small minority of assembly_points. Most will have no

Perhaps if we can say :tsunami=25 means it is 25m above sea level (the safe top

Many of the assembly points in Japan are chosen specifically because they will 
not be flooded if a nearby dam bursts, to be away from known landslide risks, 
and to have no tall buildings nearby to fall in an earthquake.

:Purpose=foobar locks you into a certian purpose, Whereas :tsunami=yes just means it is

Besides tornado, all are implied yes, so an the assembly point inherits all the

I support this. IMHO it stems from a misconception, someone wrote that 
commercial landuse is typically offices, and other people understood all 
offices must be commercial landuse.

A lot of people have an adversity to making up new tags and prefer using 
established tags even if the meaning is not fitting perfectly for the thing 
they map, but this is harmful because it devalues/blurs the meaning of the 
established tag.

IMHO landuse is never a good tag for a feature (or facility). We can have 
landuse =governmental but it doesn’t mean we should not tag the individual 
offices/facilities as well.

I’m not sure what an ambulance station is, but not all of the features I have 
in mind (a place where ambulances and their staff are parked and waiting for 
orders, usually with a coordinating office and radio unit) are emergency 
related. Some organizations only provide ambulance transports for people with 
special requirements.

In my original landuse=Civic proposal, I included all Civic buildings. 

Later, I split off those kinds of things into landuse=civic_services, as people 
suggested Civic was too broad. 

https://wiki.openstreetmap.org/wiki/Proposed_features/landuse=civic

Landuse primarily for *services* for the public: libraries, community halls, 
fire stations, police stations, etc.  

Perhaps that would be of use.

landuse areas can be as small as the land for housing plot, a factory building, 
or a convenience store. 

https://www.openstreetmap.org/#map=17/36.30597/139.32742 


look at the landuse polygons there. 

Just like parks or farmland, they can be very big - or very small. 

landuse does *not* show zoning or what is “allowed” it is used to denote the 
general purpose of the area when mapped in large polygons **or** to denote the 
extenant of a single map pin (ie, the retail land a mall sits on, the land used 
by a single factory in a industrial zone. if you are in a mixed area - you 
might have a ton of different landuses. ) 

the landuse is often several times bigger than the building, allowing the 
amenities of the site to be grouped together logically 

older tags (like school) use one tag to define the landuse as well, just train 
station or fire station. But this is a tagging discrepancy (to me). landuse is 
used for the other tags discussed. 

I would prefer that this discrepancy is evenutally resolved (landuse=school) - 
but tags like school are way too entrenched to ever be changed. 

new tags created should follow the landuse=* model, but the older way of using 
area=yes+building=yes/no is still common, and some people might like it better 
- or wonder what landuse=* is for.

I cannot find an official name or ref - but I can see their purpose. 

The next time I am on a cycling survey, I will take a picture of any small 
plaques they usually put somewhere on a man_made construction. 

I haven’t been able to find any sign onsite or web site explaining them - they 
are for someone with access to big (military) helicopters, so there is 
little-to-no public facing information at the sites themselves - but somewhere 
someone has a PDF with all the locations marked and ref'ed. 

I imagine it is not important to map them, but since I know what they are, I’d 
like to do it. 

All the signs tell people not to dump garbage, and one that says that the 
public parking lot is an emergency=assembly_point, but that is not present at 
the others - most are just stacks and stacks of blocks fenced in, waiting for a 
helicopter year after year. Some of the areas are very small - 100m2 - but the 
contents are just breakwater blocks surrounded by a fence, and they are stored 
adjacent to the levee - so there is only one purpose they could serve. you 
usually only see these kind of blocks near the ocean, protecting coastlines and 
and stacked into breakwaters.  

all of the permanent levee protection is poured concrete and boulders, so they 
are not normal building materials. 

I have found 15-20 caches of these blocks along the river in my area. Some are 
really old. The more I look, the more I find. I imagine there are several 
hundred Just around Tokyo. 

there are very few things that can stop a levee breach:

https://www.npr.org/sections/thetwo-way/2015/09/10/439106520/japanese-river-levee-fails-flooding-spurs-evacuation-order-for-130-000

Levee_breach_materials is a mouthful, but I cannot think of a shorter way to 
make the tag descriptive enough to avoid mistagging.

Re: [Tagging] Area of Firestations / Area of Ambulancestations

2018-09-21 Thread Colin Smale
There is a parallel discussion going on about
landuse=civil_administration which might include smaller areas for
individual government offices. Just wondering if an ambulance station
(or fire station or police station for that matter) might be analogous. 

I believe that landuse tagging should be monovalent and contiguous -
ultimately, every point on land should come under exactly one landuse
value, with the exception of land that has not been put to any use by
humans.

I personally think that

    amenity=ambulance_station + building=ambulance_station

would work well and fit in the schema we're using for

    * schools
    * hospitals
    * fire stations

but: it's not amenity=ambulance_station we're using at the moment. We're 
using emergency=ambulance_station -- so: How do we solve this?

It depends as some ambulance_station are located inside the hospital
campus, some other are "external services" and are only a sort of "depot"
like for taxi or buses. Personaly, I don't think landuse is a good tag for
that. Why not an amenity tag like everything else ?
(amenity=ambulance_station to be similar to amenity=fire_station ...).

We already have man_made=pipeline
It is only the nutshell, how the conduit is actually built, not what's
going inside. Substance=water is recommended and useful but not enough to
qualify the flow.
A pipeline may be opposed to tunnel. In the current situation it's
certainly a pipeline and not a tunnel.

According to https://wiki.openstreetmap.org/wiki/Key:waterway#Values
waterway=drain is suitable for discharge of superfluous water, which rain
water actually is.
As waterway=canal, a drain is always free flowing in open air. For
pressurised water conduit, use waterway=pressurised (if intake is always
below water level in operation, in the catch basin)
Then usage=sewer or usage=discharge would be ok.

All the best

Yes police and firestation areas are rendered for a while this year in osm-carto, with the same 
colour as military but without the hatching.


Thus I don't understand the 'but'.

Thanks everyone. Apologies in advance for the long reply.

@Graeme I see you tagged the node with
man_made=drain_outlet+substance=rainwater. In your example it makes 
sense
to map the underground pipe because you know exactly where it is, 
but I'd

hate for these to start rendering in the future and bits of incomplete
pipes (a few metres long) start showing up drawing over streets.

The wiki for man_made=pipeline
 says 
it is

meant for "major" pipelines, which these aren't really apply:

By using pipeline are we abusing that tag? Dictionary.com's 
definition of

pipeline also indicates that a network of pipes isn't a pipeline. I too
don't view the reticulated water network of pipes a pipeline, 
however there
would generally be a pipeline going from a water treatment plant to 
a water
reservoir/storage tank; and in the same way the network of sewerage 
drains
aren't a pipeline, but you could have a pressurised or gravity 
pipeline to

move sewage to a treatment plant.

Mark's suggestion to use man_made=sewer didn't sound right to me 
because I

always view sewers as for wastewater which must go to a treatment plant
before entering waterways. Dictionary.com seems to agree, the values 
for
manhole=*  also 
agree, this

OSM tagging proposal also agrees
,
however Wikipedia seems to indicate some people refer to stormwater 
drains

as sewers too, this might be a location thing because I found some
indication that some cities have a combined waste and rain water drain
(these obviously won't directly connect to a waterway).
substance=rainwater;sewage works though.

[...]


FWIW, I worked in the highway construction business for 14 years in 
the US.  In the industry terminology where I was, a "pipeline" 
carrying wastewater to a treatment plant was termed a sanitary sewer, 
and a pipeline carrying stormwater (rainwater) was called a storm sewer.


Humm.. I have always take 'sewer' to mean grey water.
The uk Cambridge Dictionary agrees with me.
The uk Oxford Dictionary agrees with you, and give a reference backwards.

I'll have to do some more digging (err pun).  In general I go with the 
Oxford Dictionary.




Ok .. thinking on it, if the word 'sewer' is confusing for 'native' 
English speakers (and dictionaries) it may be best avoided within OSM.

So what word/s to use?
I would think storm_water and waste_water or stormwater and wastewater 
might be reasonable values? However that does not name the pipe function.


Perhaps man_made=pipe would do? Then subtags for diameter, substance, 
pressure etc.


-
A problem with man_made=pipeline is the description 'major' ... in what 
terms is it 'major'?





Where waste and storm water is combined then only the worst term should 
be used.

Re: [Tagging] Emergency=levee_breach_materials

2018-09-21 Thread Anton Klim
Do these have anything to identify them, like a ref?
3 words for a key seems like a mouthful to me, maybe 
emergency=levee_repair/materials.
