|Tools for this tag|
Political, rather than administrative, boundaries are created as boundary type relations tagged boundary=political.
Ways for political (rather than administrative) boundaries do not need any special tags. If the way has no other tags, then boundary=political can be added, but it isn't really needed if the relation is correctly tagged.
|admin_centre||zero or one||Node representing the administrative centre, usually a town, city or village (depending of the boundary level, see place=*)|
|label||zero or one||Node representing where to draw the label.|
|(blank) or preferably outer||one or more||used for outer boundary=political member ways|
|exclave or outer||zero or more||It's often difficult to discriminate exclaves to designate one as the main "outer" area: it could be the largest one, or the area that contains the official centre, but some boundaries have several centres, or this centre is not always in the largest area. In addition there may exist exclaves that are part of the outer boundary, but which are enclaved in another boundary enclaved in the outermost area. For this reason, only "outer" and "inner" are useful geometrically.|
|enclave or preferably inner||zero or more|
This relation tag has been proposed for political boundaries when they are distinct from administrative boundaries so admin_level=* is not applicable.
Examples for use in different countries have been listed below. Feel free to document any other values used below.
||linguistic_community||Linguistic Community||The three Belgian linguistic communities do not obey the traditional hierarchic scheme of administrative subdivisions; the French and Dutch communities both include for now the Brussels-Capital Region; and the German community is a small eastern part of an arrondissement, within the Province of Liege, itself within the Region of Wallonia.|
||insular_council||Insular council||Intermediate administrative and geographic boundary (which is also electoral), between the province (admin_level=6) and the comarca (admin_level=7), dividing the Balearic Islands and the Canary Islands, created to fully cover one major island and minor islands and unpopulated islets plus their maritime domain within the same territorial waters. Question: Could this become political_division=subregion, to unify similar regional subdivisions created by autonomous communities (tagged as regions) ?|
||àmbit_funcional_territorial||Àmbit funcional territorial||This is the official denomination in catalan (in castillan ámbito funcional territorial, more or less translatable as functional territorial domain): this is the current transitory administrative status for the later evolution into veguerias, and it is part of Pla territorial de Catalunya (see http://ca.wikipedia.org/wiki/Pla_territorial_general_de_Catalunya and its external references). Referenced and used officially by the Catalan Institute of Statistics (IDESCAT), this is an an administrative status still in construction, specific to Catalunya, but still not an administrative level for Spain (it may replace in some unspecified future the existing provinces that currently subdivide the Catalan autonomous community, but in Catalunya, these structures are already effective and have their own councils, recognized by the governemnt of Catalunya). The value of this tag is provisional. Question: Could this become political_division=subregion, to unify similar regional subdivisions created by autonomous communities (tagged as regions) ?|
||euro_const||European Constituency|| Currently, only defined in 6 countries (Belgium, France, Ireland, Italy, Poland, United Kingdom), all other countries in the European Union are not split in multiple constituencies.|
In Belgium, the 3 European constituencies also match the linguistic communities (see above).
See the wikipedia article about European Parliament constituencies.
||canton||Canton||Election of the conseillers départementaux (Conseil départemental, anciennement Conseil général). See FR:Cantons in France, and map|
||circonscription_législative||Circonscription législative|| Election of the députés (Assemblée nationale). See FR:Circonscriptions législatives in France, and map|
Note that this map currently does not distinguish the different types which are overlaid (but still use the same colors). This should change with an additional filter.
||county_division||County Council Electoral Division||Are often the same as the district wards, but not always.|
