Editing UBWiki:WikiProject Geographical coordinates/region:

The <code>region:</code> parameter specifies the political region for terrestrial coordinates.  It is used to select appropriate map resources. If no <code>region:</code> parameter is provided, [[tswiki:GeoHack|GeoHack]] attempts to determine the region from the coordinates.

The region should be supplied as either a two character [[ISO 3166-1 alpha-2]] country code or an [[ISO 3166-2]] region code.

Examples of [[ISO 3166-1 alpha-2]] codes:
{{columns-list|
* '''AQ''' Antarctica
* '''AU''' Australia
* '''BR''' Brazil
* '''DE''' Germany
* '''GB''' United Kingdom
* '''HK''' Hong Kong
* '''IN''' India
* '''LK''' Sri Lanka
* '''RU''' Russia
* '''US''' United States}}

Examples of [[ISO 3166-2]] region codes:
{{columns-list|
* '''DE-TH''' Thuringia, Germany
* '''GB-BIR''' Birmingham, England
* '''NO-03''' Oslo, Norway
* '''US-NY''' New York state, US}}

The oceans have the following Wiki assigned code elements per [[:de:Vorlage:Coordinate#Ozeane]].
* '''XN''' Arctic Ocean
* '''XA''' Atlantic Ocean
* '''XI''' Indian Ocean
* '''XP''' Pacific Ocean
* '''XS''' Southern Ocean

In addition, two Wiki assigned code elements can be used with {{tl|coord}}:
* '''XZ''' for objects in or above international waters (similar to [[UN/LOCODE]]).
* '''ZZ''' for use in examples.
