Re: [Tagging] Disputed area

2015-07-25 Thread Eric SIBERT

I did some try.

* Mont-Blanc area claimed by France and Italy but occupied by nobody.
I have split the boundary into two branches (an awful job considering 
the number of administrative relations involved).


I defined an area with:
disputed_area=yes
dispute:claim:FR=yes (area claim by France)
dispute:claim:IT=yes (area claim by l'Italie)
dispute:recognized:FR=yes (dispute is recognized as such by French 
authorities)
dispute:recognized:IT=yes (dispute is recognized as such by Italian 
authorities)

dispute:wikipedia:fr=Histoire_de_la_frontière_sur_le_mont_Blanc

I added the area both to relations France and Italia (admin_level=2) 
with role dispute:recognized (each government recognize that there is an 
area within his border that is subject to dispute).



* Juan de Nova island. French island. Claim by Madagascar. French 
government don't really recognize that there is a conflict (I think this 
is the most common case of disputed area).


I added to the island perimeter which is already the French boundary:
disputed_area=yes
dispute:claim:MG=yes
dispute:recognized:FR=no
dispute:recognized:MG=yes

Added to Madagascar relation with dispute:claim role.
Not added to France relation because French government don't acknowledge 
the dispute.


* Tromelin Island. French island. Claimed by Mauritius. French 
government accepted to share fishing right with Mauritius that I 
consider as an acknowledgment of the dispute.


I added to the island perimeter which is already the French boundary:
disputed_area=yes
dispute:claim:MU=yes
dispute:recognized:FR=yes
dispute:recognized:MU=yes

Added to Mauritius relation with dispute:claim role.
Added to France relation with dispute:recognized role.


I see several drawbacks.
- looking at the disputed territories proposal 
(http://wiki.openstreetmap.org/wiki/Proposed_features/DisputedTerritories), 
I would say that my use of recognized is not well suited. Recognized 
would be better fits for foreign governments or international 
organizations (like UN) that recognized the 'de facto' situation. May be 
dispute:acknowledge:CC=* would be best suited to indicate that a 
government recognize that there is a dispute.

- there are several redundancies.
If country AA claims an area out of his 'de facto' boundaries, it is 
both marked as dispute:recognized:AA=yes and added to AA relation with 
dispute:claim role.
If country BB recognize that there is a disputed area within his 'de 
facto' boundaries it is both marked as dispute:recognized:BB=yes and 
added to BB relation with dispute:recognized role.


Indeed, all roles dispute:claim are supposed outside the country 
boundaries and all roles dispute:recognized are supposed inside the 
country boundaries. May be one role should be enough for both.


Or no role/inclusion in relation at all.

What are all the disputed areas within CC and recognized as such by CC 
government? Request all disputed_area=yes within CC relation and with 
dispute:recognized:CC=yes.


Last question : how to indicate that an area want its independence?

Re: [Tagging] Disputed area

2015-07-23 Thread Eric Sibert

I think a good test case for testing if this can handle ongoing and complex
conflicts would be Kashmir, as it's currently five-ways disputed between
Pakistan, India, China, a Kashmir separatist/freedom/independence movement,
and recently displaced-from-Afghanistan irregular Islamic fundamentalist
forces.


I would be cautious about not stabilized conflicts and therefore  
exclude the last group and just focus on the first four claimers. In  
the same idea, I would not try to describe the situation in East  
Ukraine.


First question : can you draw current de facto borders? The northern  
part of India/Pakistan border?


Second question : can you draw areas with uniform claims and de facto  
situation inside?

Re: [Tagging] Disputed area

2015-07-23 Thread Eric Sibert

Overlapping should be the first step to mapping a dispute. Then if you want
to add dispute attributes, you could create a new multipolygon with areas
in question, and add dispute specific tags, wikidata tags, and similar.


In my previous message, I proposed to create a relation for the  
disputed area but a single polygon may be enough in most cases. A  
multipolygon may be used if the same dispute deals with several areas  
(like one country claiming several islands of another country at the  
same time).

Re: [Tagging] Disputed area

2015-07-23 Thread Eric Sibert
Yes, some disputed areas are more stable and, in osm, one may focuses  
first on it.


In a lot of cases, there is de facto one country administrating the  
area. We should use the de facto aspect to draw a closed  
boundary=administrative.


Then we may add to the relation disputed areas with different roles  
whenever they are inside or outside the de facto boundaries.


The disputed area may be itself defined by a relation including the  
area, the boundaries claimed by each government and may be some tags  
to indicate if the disputed area is recognized as such by each  
government and/or attributed to one specific government by some  
international organization (for de jure aspect?).


For my initial case (Mont-Blanc between fr and it), there is no de  
facto occupying country. I would split the boundary into two branches  
corresponding to each government claim. Define a disputed_area  
relation with:

- each branch
- the area
- claimed by France
- claimed by Italy
- dispute acknowledged by France
- dispute acknowledged by Italy
- dispute acknowledged by European Union
Put each branch in the corresponding country relations. Add to each  
country relation a disputed_area_inside with the disputed relation.
The main drawback is that there is an overlap between France and Italy  
that may stress some tools.


Gibraltar : there is a de facto occupying country. I would not split  
the boundary into two branches. Define a disputed_area relation with:

- the UK branch surrounding Gibraltar
- the earth border between UK and Spain
- the area
- claimed by Spain
- dispute acknowledged by Spain
- dispute acknowledged by Uk
Maintain the earth border in the corresponding country relations.
Add to UK relation a disputed_area_inside with the disputed relation.
Add to Spain relation a disputed_area_outside with the disputed relation.

Area claimed by nobody between Egypt and Sudan?
Split the boundary into two branches according to each government.
Define a disputed_area relation with:
- the Sudan branch
- the Egypt branch
- the area
(no claim, no dispute acknowledgement).

Is such a schema suitable for the Indian/China case? Does is allow to  
draw a map like the one presented?

2015-07-21 Thread Eric Sibert

One thing that perhaps might want to be captured in other disputes is
what happens when one country actually occupies and controls the
disputed territory.  There, there's a de facto border and a claim.


Yes, I started with the easy case where not country is occupying the  
disputed area and both countries agree on the limits of the disputed  
area. There should be a similar case between USA and Canada for  
islands near Vancouver.


Although not so completely pacific is the case of Perejil/Tourah  
island between Spain and Morocco with status quo and no one occupying  
it.


In opposite there are a lot of claims that seems mostly theoretical  
like Spain other Gibraltar, Morocco other Ceuta and Melilla,  
Madagascar other Juan de Nova and Europa islands (both inhabited but  
controlled/administrated by France)...
Tromelin island controlled by France but with fishing rights share  
with Maurice republic that is claiming the island.


So I don't know were to put the limit on which territories should be  
tagged as disputed in OSM. May be we can start with areas recognized  
as such by booth governments and not occupies by any one :-p


There is also the case of sea/water disputes like the one recently

Re: [Tagging] Current status of the key smoothness=*

(I think of the roads we drove in Kenya), so any input is welcome even if it
isn't perfect. We ran into some nasty surprises during our trip because the
road quality wasn't tagged at all.


+1.

I also widely use smoothness=* in Madagascar. Indeed, I use it to  
describe practicability of roads or tracks for 4 wheels motor  
vehicles, in somehow to answer the question: what kind of vehicle do I  
need to use this road?


Despite using it often, I still have to check the wiki time to time to  
be sure about values definition. I even more dislike tracktype=gradeN  
that is using numerical values.


Maybe, it is time to define a new key/values. We already have  
mtb:scale and sac_scale.


For instance, practicability for cars:

practicability=*

practicability=no (damaged road)
practicability=tractor_only
practicability=fourwheeldrive_only (and not 4WD_only to avoid abbreviation)
practicability=highclearance_only
practicability=normal (default value)
practicability=lowclearance

Subjectivity still remains. One may consider a road as usable with a  
high clearance car because it is used by 404 taxi-brousse when another  
one may not want to use his Porche Cayenne SUV on it.


It doesn't really describe smoothness. A road usable with normal  
vehicles may be driven at 100 km/h or 20 km/h, depending on smoothness.


One may define some side scales like:

practicability:bicycle=mountainbike_only/trekkingbike_only/citybike/all(defaut)
practicability:motorcycle=*

I agree with your suggestion of using boot bridge=yes and ford=yes as it 
is usually a bridge but sometime behaves like a ford. I would avoid 
flood_prone=yes as it is made to be used when reasonably submerged. 
Adding depth=0 (or -0.5 ?) to indicate that the ford aspect is usually

[Tagging] Ford and other river crossing : (was : waterway=wadi problem)

My apologize for switching the discussion (so I change the title  
accordingly) and also for slowly answering.


First, I was not aware of depth=* use recommendation with ford=yes  
although it is in the wiki for years.


Let me back to Madagascar. We have:

- unpaved road crossing permanent river without specific equipment
ford=yes
surface=unpaved
depth0

- unpaved road crossing permanent river with specific equipment  
(usually made of concrete, radier in French, not sure on the correct  
term in English: raft???)

ford=yes
surface=paved/concrete
depth0

- unpaved road crossing intermittent river without specific equipment
ford=yes
surface=unpaved
depth=0
May we use intermittent=yes/seasonal/flood/winter... to indicate  
period/frequency submersion?


- unpaved road crossing intermittent river with specific equipment
ford=yes
surface=paved/concrete
depth=0
intermittent?

- paved road crossing permanent river (of course with specific equipment)
ford=yes
surface=paved/concrete
depth0

- paved road crossing intermittent river
ford=yes
surface=paved/concrete
depth=0
intermittent?

Do we have also to use flood_prone=yes or (ford=yes / depth=0) already  
imply that it is subject to flooding?


I don't like the wiki page on flood_prone. It is telling that the main  
difference between ford and flood_prone is the danger aspect. Indeed,  
looking at illustrations, especially at the third one, I just see a  
regular ford with depth scale and so on.


I have one last case: some low profile bridge (without parapet) may be  
submerged after heavy rain but may be still usable if water depth  
above the bridge in not too high. How to tag this?

cuisine
operator

So renderer can easily handle a lot of cases. We can then add a tag to

[Tagging] Emergency lane used by PSV at rush time

2012-10-14 Thread Eric SIBERT

Hi,

I'm translating the lanes=* wiki page into French. And some cases are 
coming into my mind :-p


On a motorway, the emergency lane can be used by psv (bus and taxi) when 
there is traffic jam on the usual lanes. There is no predefined hours. 
Just, when traffic jam is detected, light signal are switched to 
indicate it.


So, how would you tag this considering lanes=* definition and new 
Conditional restrictions?


Default is
lanes=2
oneway=yes

but considering that lanes=* should include lanes that are available to 
traffic at certain restricted times, it should be lanes=3


lanes:psv:conditional= 1 @ rush_time

but this will suggest that all 3 lanes are available for all vehicles 
out of rush time.


Some other suggestions?

Back to my initial problem

lanes=2

lanes:condtional = 3 @ traffic_jam
lanes:psv:conditional = 1 @ traffic_jam

Basic data users just need to understand the first key. More advanced 
one may use the two last.


lanes=* wiki would need to be modified to not count temporary lanes. It

Re: [Tagging] Reconstructing «Dificult passability» proposal to «Obstacle»

2012-10-12 Thread Eric Sibert

Hi,

During my last travel in Africa, I was thinking on how to map  
obstacles on road. So I support your proposal but in a generalized  
way, not only for pedestrian or bicycle. And I take the opportunity to  
review what I observed:
- a narrow bridge i.e. you can't cross a vehicle in opposite  
direction. We may use width=* but it is difficult to get it precisely.  
obstacle=narrowness
- a bridge or a raft with a bad link to the road/track i.e. a step at  
each end of the bridge/raft. obstacle=unevenness ? or obstacle=step?  
For me unevenness is to soft for what you describe.

- a hole in the road.
  * A small hole you can drive other at full speed but that may  
surprise you when driving during night.
  * A medium hole where you have to use the other side of the road at  
full speed if nobody is arriving in front

  * A big hole where you have to slow down and drive inside.
(For full uneven sections, I use smoothness=*).
- a road on a dam or a bridge have been damaged : a bailey bridge  
(http://en.wikipedia.org/wiki/Bailey_bridge) have been temporary (for  
ten years ;-) ) added on it.


I would no use obstacle for thinks that are deliberate and/or in their  
initial state.


For river and water. If there is water year around (or large fraction  
of the year) : ford=yes. Only flooded few days a year (after heavy  
rain), flood_prone=yes. Use surface=* to indicate whenever you are  
just driving in the river or if there is some raft build. Seasonal?  
Use seasonal=yes in conjunction with access:conditional=* to indicate  
approximative closing period (discussed recently on this mailing list.  
I will update the wiki according soon...).


Same with traffic_calming, check points...

HOT is also dealing with obstacle :

[Tagging] Narrow Bridge (was: Reconstructing «Dificult passability» proposal to «Obstacle»)

2012-10-12 Thread Eric SIBERT

- a narrow bridge i.e. you can't cross a vehicle in opposite
direction. We may use width=* but it is difficult to get it
precisely. obstacle=narrowness


It's slightly offtopic, but wouldn't it be logical to use car as a non
accurate unit of length? So you can have a tag like width=1car or
width=1.5car.



I like it :-)

In Europe, I found :
1 car used 2 times
wide enough for a car used 1 time

Not wildly used.

Indeed, as pointed out by Martin, I have to use lanes=1. I had a 
misunderstanding with the lanes=* key. I thought lanes=* indicated the 
number of lanes in each direction, not the total number in both 
directions. The French wiki lanes=* page need a strong update, compared 
to the English one (todo list...).


So, I will go on with lanes=1.

Re: [Tagging] Reconstructing «Dificult passability» proposal to «Obstacle»

2012-10-12 Thread Eric SIBERT

you could use lanes=1 on the narrow parts.


Agree.



- a bridge or a raft with a bad link to the road/track i.e. a step at each
end of the bridge/raft. obstacle=unevenness ? or obstacle=step? For me
unevenness is to soft for what you describe.



split the way and put a short highway=steps, step_count=1


No. It would indicate that it can't be used by vehicles.


- a road on a dam or a bridge have been damaged : a bailey bridge
(http://en.wikipedia.org/wiki/Bailey_bridge) have been temporary (for ten
years ;-) ) added on it.



is this an obstacle, or is it simply another type of bridge
construction? If it is an obstacle the tagging should line out in what
the obstacle consists (smoothness, width, maxweight, ...)


It's first a lanes=1 and second short connecting slopes at each end. 
Something no so far from the steps I mentioned earlier i.e. you have to 
slow down at entrance and exit of the bridge.

Re: [Tagging] Seasonnal roads

2012-10-10 Thread Eric Sibert

For mountain pass in Alps, this could be just

access:conditional = no @ Nov-Apr




That seems logical to me. One word on using access:conditional though -
this would indicate no access, including on foot.


In somehow, we may consider that the road does not exist in winter due  
to the large amount of snow over it. I mostly use it during ski touring.



For more details see [1]
and [2]. Essentially there is a hierarchy of subcategories for
transportation modes.
[2] http://wiki.openstreetmap.org/wiki/File:Access_hierarchy_simple.png


This scheme should be more wildly used. It seems to be use only in the  
German wiki.

I'm looking how to tag a road with seasonal opening or closing. ...




Have you tried: http://wiki.openstreetmap.org/wiki/Conditional_restrictions


May I improve the wiki on seasonal=* to indicate that it would be nice  
to use it in conjunction with Conditional_restrictions?

 I'm looking how to tag a road with seasonal opening or closing. ...
 Up to now, I was using opening_hours=* with Nov-Apr off.

Have you tried: http://wiki.openstreetmap.org/wiki/Conditional_restrictions


I had a look some time ago but without thinking at seasonal roads.

 Work is under way to help make the page clearer,

+1


[...] but essentially your tag would be:

* vehicle:conditional = no @ Nov-Apr


For mountain pass in Alps, this could be just

access:conditional = no @ Nov-Apr

For African tracks, something like

smoothness:conditional = horrible @ May-Oct
smoothness:conditional = very_horrible @ Nov-Apr

or

smoothness = horrible
smoothness:conditional = very_horrible @ Nov-Apr


All with seasonal=yes to indicate the random aspect of the time condition.

Do you agree?

Re: [Tagging] Seasonnal roads

2012-10-09 Thread Eric SIBERT

One of the main mountain highways here is closed to licensed vehicles
during the winter months, but snowmobiles are permitted.  Would
vehicle:conditional apply to snowmobiles?


I also have a similar problem with road that are use in winter for 
nordic (or not) ski. Up to now, I added a second way for winter 
activities on top the way for the summer road.

[Tagging] Seasonnal roads

2012-10-06 Thread Eric SIBERT

Hi,

I'm looking how to tag a road with seasonal opening or closing. Typical, 
mountain pass are closed in winter due to snow. Usual opening and 
closing dates are published (like open from week 24 to 41). In opposite, 
some roads on ice are only opened in winter. In Africa, some unpaved 
roads are usually closed during rainy season. Up to now, I was using 
opening_hours=* with Nov-Apr off. But I was looking for something 
more generic that can indicate the random aspect.


I saw the proposal seasonal=* :
http://wiki.openstreetmap.org/wiki/Key:seasonal

Use in Europe : yes (497), no (19), winter (12), summer (9), * (2), 
Spring, Summer, Fall (1), Yes (1)


Use in Africa : year_round (171), yes (75), wet_season (32), 
cannot_determine (27), another_pattern (16), dry_season (7), na_dn (1), 
dry_weather (1)


seasonal=* does not indicate typical opening period.

Any suggestion?

Éric
