[OSM-talk-be] boundary names and my program

[A.Pirard.Papou]

Hi,

I have improved my border scanning program.
For additional fun, I computed the length of borderlines between 
municipalities.
You can see the Province Liège result @ 
http://wiki.openstreetmap.org/wiki/User:Papou/OSM.
I intend to check the borders for various kinds of errors later and 
build a worksheet (1).
At present, it only builds that worksheet for persons to reserve and 
mark completion of tasks.
Click on the headers to sort the columns, especially by length.

I thought I could make a shortest-border contest, but you can see the 
problem: a 3 meter winner!
That's because, despite the practice is discouraged, Mr Verdy has been 
using paths as borders.
After ignoring streams,  paths and barbed wire borders, it turns out 
that the winner is:


      Deutschland — Belgique / België / Belgien

Congratulations !!!
What is that?  That's the name Mr Verdy has given it instead of a simple 
commune X commune Y.
But it's easy to find which border it is by looking to which areas it 
belongs:
Verviers (town, arrondissement, province?), Deutschsprachige 
Gemeinschaft, Deutschland (Landmasse), Deutschland, Rheinland-Pfalz, 
Burg-Reuland, Liège (town, arrondissement, province?), België - Belgique 
- Belgien, Belgigue / België / Belgien (land mass),  Deutschland — 
Belgique / België / Belgien, Eifelkreis Bitburg-Prüm, Eifel, Sevenig 
(Our), Arzfeld and ... 1259856.


      Conclusions:

In order for my program (and others) to work and be useful,

  * *the names of the borders must be Municipality A — Municipality B*
    and not 30 times Belgium — Germany or Liège —Verviers.  Note that
    this is border identification. The names Belgium an Germany are
    taken from the relations and written on the borderline to indicate
    country limits anyway.
  * proper ways must be used for borders, not paths, railways, streams,
    landuse etc...

*Can we all agree on that?*

(1) I can check that each border has 2 communes and that the 
municipality and border names are the same.  I can check that the 
municipality has a well formed phone number, is_in, and a huge lot of 
things like that:  I will ask you the rules you think of.

Cheers,

Papou André.
