{{Coord how-to}}

__TOC__

==Purpose==
{{tlf|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}}.
* If the coordinates were [[meta:Wikidata/Notes/Inclusion syntax|transcluded from Wikidata]], use {{tl|WikidataCoord}}.

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 also accepts and displays coordinates formatted as degrees and decimal minutes as found on charts and maritime references.

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 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 (in desktop view only; title coordinates do not display in mobile view)—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 [[#Per-user_display_customization|customize]] how coordinates appear in their browsers.


You can extract information from the Coord template for use in mathematical expressions. For details, see [[:Module:Coordinates]].

==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 [https://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?]{{dead link|date=August 2020}}. However, if multiple title coordinates appear on a single page, they will overlap, making them illegible.

== Usage ==
'''{{coord|'''''latitude'''''|'''''longitude'''''|'''''[[#1|coordinate parameters]]'''''|'''''[[#2|template parameters]]'''''}}'''
'''{{coord|'''''dd'''''|'''''N/S'''''|'''''dd'''''|'''''E/W'''''|'''''[[#1|coordinate parameters]]'''''|'''''[[#2|template parameters]]'''''}}'''
'''{{coord|'''''dd'''''|'''''mm'''''|'''''N/S'''''|'''''dd'''''|'''''mm'''''|'''''E/W'''''|'''''[[#1|coordinate parameters]]'''''|'''''[[#2|template parameters]]'''''}}'''
'''{{coord|'''''dd'''''|'''''mm'''''|'''''ss'''''|'''''N/S'''''|'''''dd'''''|'''''mm'''''|'''''ss'''''|'''''E/W'''''|'''''[[#1|coordinate parameters]]'''''|'''''[[#2|template parameters]]'''''}}'''

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:

*'''Coordinate parameters''' 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.

*'''Template parameters''' 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; coordinates are displayed in desktop view only; title coordinates do not display in mobile view)
::** 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—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 decimal degrees format.
::* <code>format=dms</code> reformats the coordinates to degrees | minutes | seconds 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.
:* '''qid=''' specify Q item to display the coordinates of. Used primarily by Wikidata powered infoboxes.

==Helper functions==
Helper functions are available to manipulate the output from {{tl|Coord}} when it appears in a container template such as an infobox.

===To extract the latitude from a Coord template===
Use:

<code><nowiki>{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|lat}}</nowiki> </code> → {{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|lat}}

and similarly to extract the longitude, use:

<code><nowiki>{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|long}}</nowiki></code> → {{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|long}}

:'''Note: this method removes the microformat markup, and should not be used inside templates which emit parent microformats, such as infoboxes or table-row templates.'''

=== Displaying all coordinate links on one map ===
The template {{tl|GeoGroup}} can be used in an article with coordinates. This template creates links to mapping services 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.

== 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.

==Per-user display customization==

{{UF-coord-classes}}

==Incorrect uses and maintenance categories==
The template has some input checks built in. Most errors display a '''bold, red''' message inline and categorize the article in the [[Wikipedia:Hidden category|hidden]] [[Wikipedia:Categorization#Non-article and maintenance categories|maintenance category]] '''[[:Category:Pages with malformed coordinate tags|Pages with malformed coordinate tags]]'''. There {{#IFEQ:{{PAGESINCATEGORY:Pages with malformed coordinate tags}}|1|is currently '''1''' page|are currently '''{{PAGESINCATEGORY:Pages with malformed coordinate tags}}''' pages}} in that category. See the category description for further instructions.

==Internals==
This template is completely powered by the [[Wikipedia:Lua|Lua module]] {{tlm|Coordinates}}.

===Class names===
The class names '''geo''', '''latitude''' and '''longitude''' are used to generate the microformat and '''MUST NOT''' be changed.

===History===
This template used to use a lot of [[Template:Coord/doc/internals|sub templates]] but these have all been replaced by {{tlm|Coordinates}}.

===Template Data===
This template uses overloading which does not work well with the [[Wikipedia:TemplateData|VisualEditor/TemplateData]]. Consider using "Edit source" instead of the visual editor until this defect is corrected. To facilitate visual editing in the meantime, consider using {{tl|coordDec}} for signed decimal degrees, {{tl|coordDMS}} when degrees minutes and seconds are specified, and {{tl|coordDM}} when just degrees and minutes are given.

This template does not work well with the Visual Editor, consider using {{coordDec}} for signed decimal degrees, {{coordDMS}} when degrees minutes and seconds are specified {{coordDM}} when only degrees and minutes are specified.
