__TOC__

==Purpose==
{{Tld|Coord}} provides a standard notation for encoding locations by their [[latitude]] and [[longitude]] coordinates. It is primarily for specifying the [[World Geodetic System|WGS84]] geographic coordinates of locations on [[Earth]], at the same time emitting a machine-readable [[Geo (microformat)|Geo microformat]]. However, it can also encode locations on natural satellites, dwarf planets, and planets other than Earth.

* To specify celestial coordinates, use {{tl|Sky}} instead.
* Tag articles which lack coordinates (but need them) with {{tl|Coord missing}}.
* If the subject's location is truly unknown or disputed, note this with {{tl|coord unknown}}.

See also [[Wikipedia:WikiProject Geographical coordinates]].

==Features==
Latitude and longitude may be specified (with appropriate precision) either in decimal notation or as degrees/minutes/seconds.  By default, coordinates appear in the format used to specify them.  However, the <code>format=</code> parameter can be used to force display in a particular format. 

The template displays the formatted coordinates with a [[hyperlink]] to [[tswiki:GeoHack|GeoHack]]. GeoHack displays information customized to the location, including links to external mapping services.

For [[Earth|terrestrial]] locations, a blue globe ([[Image:Erioll_world.svg|18px]]) appears to the left of the hyperlink.  Clicking on the globe activates the [[:meta:WikiMiniAtlas|WikiMiniAtlas]] (requires [[JavaScript]]).

By default, coordinates appear "in line" with the adjacent text.  However, the <code>display=</code> parameter can be used to move the coordinates up near the page title—or display them in both places at once.

The template outputs coordinates in three formats:
* Degree/minutes/seconds ("DMS", precision is degrees, or degrees/minutes, or degrees/minutes/seconds, based on input precision).
* Decimal degrees (varying the number of decimal places based on input precision)
* A machine readable [[Geo (microformat)|Geo microformat]].

Logged-in users can customize how coordinates appear in their browsers.

==Caveats==
The template '''must not''' be modified without prior discussion.

Tools which read Wikipedia database dumps (such as [[Google Earth]]) often ignore inline coordinates. To ensure that coordinates are seen by these tools, one set should be displayed beside the title. See [http://support.google.com/earth/bin/answer.py?hl=en&answer=2395280 How do I get my Wikipedia article to show up in the Google Earth Geographic Web layer?].  However, if multiple title coordinates appear on a single page, they will overlap, making them illegible.

==Superseded templates==

This single template supersedes {{tl|coor d}}, (and others in that family which have since been redirected to it), plus the [{{fullurl:Special:PrefixIndex|from=Geolinks&namespace=10}} Geolinks] and [{{fullurl:Special:PrefixIndex|from=Mapit&namespace=10}} Mapit] templates. Most parameters can be used as before – see [[#Usage|Usage]].

Examples:
<table class="wikitable">
<tr><td>&#123;{coord|10.2|N|-20.3|E|'''type:'''city}&#125;</td><td>Replaces &#123;{coor d|10.2|N|-20.3|E|city}&#125;</td></tr>

<tr><td>&#123;{coord|44.4|-111.1|'''type:city_region:US'''|display=inline,title}&#125;</td><td>Replaces &#123;{Geolinks-'''US-cityscale'''|44.4|-111.1}&#125;</td></tr>

<tr><td>&#123;{coord|51.01234|-1.56789|'''type:landmark_region:GB'''|display=inline,title}&#125;</td><td>Replaces &#123;{Geolinks-'''UK-buildingscale'''|51.01234|-1.56789}&#125;</td></tr>

<tr><td>&#123;{coord|-35.5|150.1|'''type:landmark_region:AU'''|display=inline,title}&#125;</td><td>Replaces &#123;{Mapit-'''AUS-suburbscale'''|lat=-35.5|long=150.1}&#125;</td></tr>

<tr><td>&#123;{coord|12|34|12|N|45|33|45|W|'''display=title'''}&#125;</td><td>Replaces &#123;{'''CoorHeader'''|12|34|12|N|45|33|45|W}&#125;</td></tr>

</table>

== Usage ==
 '''&#123;{coord|'''''latitude'''''|'''''longitude'''''|'''''[[#1|coordinate parameters]]'''''|'''''[[#2|template parameters]]'''''}&#125;'''
 '''&#123;{coord|'''''dd'''''|'''''N/S'''''|'''''dd'''''|'''''E/W'''''|'''''[[#1|coordinate parameters]]'''''|'''''[[#2|template parameters]]'''''}&#125;'''

The hemisphere identifiers (''N/S'') and (''E/W''), if used, must be adjacent to the enclosing pipe "'''<code>|</code>'''" characters, and cannot be preceded or succeeded by spaces.

There are two kinds of parameters, all optional:

*<span id="1">'''Coordinate parameters'''</span> are parameters that {{tl|Coord}} passes to the map server. These have the format ''parameter:value'' and are separated from each other by the underscore character ( _ ). The supported coordinate parameters are ''dim:'', ''globe:'', ''region:'', ''scale:'', ''source:'', and ''type:''. See [[#Coordinate parameters|coordinate parameters]] for details and examples.

*<span id="2">'''Template parameters'''</span> are parameters used by the {{tl|Coord}} template.  These have format ''parameter=value'' and are separated from each other by the pipe character ( | ). The supported template parameters are ''display='', ''format='', ''name='', and ''notes=''.
:* '''display=''' can be one of the following:
::* <code>display=inline</code> – Display the coordinate inline (default)
::* <code>display=title</code> – Display the coordinate at the top of the article, beside the article's title (replaces {{tl|coor title dms}} family)
::** shortcut: <code>display=t</code>
::* <code>display=inline,title</code> – Display the coordinate both inline and beside the article's title (replaces {{tl|coor at dms}} family)
::** shortcut: <code>display=it</code>
::* <code>display=title,inline</code> has the same effect as <code>display=inline,title</code>
::Note: the <code>title</code> attribute indicates that the coordinates apply to the entire article, and not just one of (perhaps many) places mentioned in it &mdash; so it should only be omitted in the latter case. 
:* '''format=''' can be used to force ''dec'' or ''dms'' coordinate display.
::* <code>format=dec</code> reformats the coordinates to <span style="text-decoration:underline;">decimal degrees</span> format.
::* <code>format=dms</code> reformats the coordinates to <span style="text-decoration:underline;">degrees | minutes | seconds</span> format.
:* '''name=''' can be used to annotate inline coordinates for display in map services such as the [[:meta:WikiMiniAtlas|WikiMiniAtlas]]. If omitted, the article's title (PAGENAME) is assumed.
::Note: a ''name='' parameter causes {{tl|Coord}} to emit an [[hCard]] [[microformat]] using that name, ''even if used within an existing hCard''. Do not use when the name is that of a person (e.g for a gravesite), as the generated hCard would be invalid. Also, do not use square brackets in names.
:* '''notes=''' specifies text to be displayed immediately following the coordinates.  This is primarily intended for adding footnotes to coordinates displayed beside the title.

== Displaying all coordinate links on one map ==
The template {{tl|GeoGroup}} can be used in an article with coordinates. This template creates links to Google Maps and Bing which display all the coordinates on a single map, and links to other services which allow the coordinates to be used or downloaded in a variety of formats.

== Examples ==

== Coordinate parameters ==
The first unnamed parameter following the longitude is an optional string of coordinate parameters, separated by underscores. These parameters help [[tswiki:GeoHack|GeoHack]] select suitable map resources, and they will become more important when [[meta:Wikimaps|Wikimaps]] becomes fully functional.
