Template:Coord
 | This template is used on many pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
 | This is a candidate to have a transwiki guide. Due to the complexity of the project or template, this guide will help editors adapt it to a remote wiki when this cannot be done by simply copying the codes of one single template. If you know this template syntax very well, feel free to start the guide in Template:Coord/Transwiki guide. Once the transwiki guide page is complete, replace this tag by {{Transwiki guide}}. |
 | This template uses Lua: |
navbox or vertical-navbox attributes are not displayed on the Mobile Web site for Wikipedia, which accounts for approximately 45% of readers.  | This template does not display in the mobile view of Wikipedia; it is desktop only. Read the documentation for an explanation. |
Quick guide
To add 57°18′22″N 4°27′32″W / 57.30611°N 4.45889°W to the top of an article, use {{Coord}}, thus:
These coordinates are in degrees, minutes, and seconds of arc. "title" means that the coordinates will be displayed next to the article's title at the top of the page and before any other text or images. |
To add 44°06′43″N 87°54′47″W / 44.112°N 87.913°W to the top of an article, use either
(which does not require minutes or seconds but does require the user to specify north/ south and east/west) or
(in which the north and east are presumed by positive values while the south and west are negative ones) These coordinates are in decimal degrees. |

Optional coordinate parameters follow the longitude and are separated by an underscore ("_"):
Other optional parameters are separated by a pipe ("|"):

Purpose
{{Coord}} provides a standard notation for encoding locations by their latitude and longitude coordinates. It is primarily for specifying the WGS84 geographic coordinates of locations on Earth, at the same time emitting a machine-readable Geo microformat. However, it can also encode locations on natural satellites, dwarf planets, and planets other than Earth.
- To specify celestial coordinates, use {{Sky}} instead.
- Tag articles which lack coordinates (but need them) with {{Coord missing}}.
- If the subject's location is truly unknown or disputed, note this with {{Coord unknown}}.
- If the coordinates were transcluded from Wikidata, use {{WikidataCoord}}.

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 format= 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 GeoHack. GeoHack displays information customized to the location, including links to external mapping services.
For terrestrial locations, a blue globe (
) appears to the left of the hyperlink. Clicking on the globe activates the WikiMiniAtlas (requires JavaScript).
By default, coordinates appear "in line" with the adjacent text. However, the display= 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.
Additional features
- Logged-in users can customize how coordinates appear in their browsers.
- You can get coordinates from Wikidata by transcluding this template without any numbered arguments.
- You can extract information from the Coord template for use in mathematical expressions. For details, see Module:Coordinates.
- All coordinates used in a page through this template are registered in the geosearch API. If a coordinate is using title display, then these coordinates will be marked as the primary coordinates with regards to the page and therefore the topic of that page.
Caveats
The template must not be modified without prior discussion. External tools can depend on the format of both the wikitext and/or the generated html.
Usage
{{coord|latitude|longitude|coordinate parameters|template parameters}}
{{coord|dd|N/S|dd|E/W|coordinate parameters|template parameters}}
{{coord|dd|mm|N/S|dd|mm|E/W|coordinate parameters|template parameters}}
{{coord|dd|mm|ss|N/S|dd|mm|ss|E/W|coordinate parameters|template parameters}}
The hemisphere identifiers (N/S) and (E/W), if used, must be adjacent to the enclosing pipe "|" characters, and cannot be preceded or succeeded by spaces.
There are two kinds of parameters, all optional:
- Coordinate parameters are parameters that {{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 for details and examples.
- Template parameters are parameters used by the {{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:
display=inline– Display the coordinate inline (default)display=title– Display the coordinate at the top of the article, beside the article's title (coordinates are displayed in desktop view only; title coordinates do not display in mobile view)- shortcut:
display=t
- shortcut:
display=inline,title– Display the coordinate both inline and beside the article's title- shortcut:
display=it
- shortcut:
display=title,inlinehas the same effect asdisplay=inline,title
- Note: the
titleattribute 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. Additionally the title option will mark the coordinates as the primary coordinates for the page (and topic of the page) in the geosearch API.
- format= can be used to force dec or dms coordinate display.
format=decreformats the coordinates to decimal degrees format.format=dmsreformats the coordinates to degrees | minutes | seconds format.
- name= can be used to annotate inline coordinates for display in map services such as the WikiMiniAtlas. If omitted, the article's title (PAGENAME) is assumed.
- Note: a name= parameter causes {{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 {{Coord}} when it appears in a container template such as an infobox.
To extract the latitude from a Coord template
Use:
{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|lat}} → 57.30611
and similarly to extract the longitude, use:
{{#invoke:coordinates|coord2text|{{Coord|57|18|22|N|4|27|32|E}}|long}} → 4.45889
- 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 {{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 GeoHack select suitable map resources, and they will become more important when Wikimaps becomes fully functional.
type:T
The type: parameter specifies the type of location for reverse mapping (for instance, to select a marker icon in the WikiMiniAtlas).
It also sets the map scale, which can however be overridden by dim: or scale:.
Valid types are:

scale:N
The scale: parameter specifies the desired map scale as 1:N, overriding the scale implied by any type: parameter.
GeoHack uses scale: to select a map scale for a 72 dpi computer monitor. If no dim:, type:, or scale: parameters are provided, GeoHack uses its default scale of 1:300,000.

dim:D
The dim: parameter defines the diameter of a viewing circle centered on the coordinate. While the default unit of measurement is metres, the km suffix may be appended to indicate kilometres.
GeoHack uses dim: to select a map scale such that the viewing circle appears roughly 10 centimetres (4 in) in diameter on a 72 dpi computer monitor. If no dim:, type:, or scale: parameters are provided, GeoHack uses its default viewing circle of 30 kilometres (19 mi).
| Subject | View diameter | Markup | Result |

region:R
The region: parameter specifies the political region for terrestrial coordinates. It is used to select appropriate map resources. If no region: parameter is provided, 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:
- 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:
- 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 {{coord}}:
- XZ for objects in or above international waters (similar to UN/LOCODE).
- ZZ for use in examples.

Very rough mapping is provided on geohack for almost all supported globes. The pop-out WikiMiniAtlas system provides limited mapping for Moon, Mars, Mercury, Venus, Io, and Titan, as of February 2021[update].
The maps roughly implies a coordinate reference system, but does not clearly specify one (unlike Earth's WGS84). Since the template defaults to east longitude, the |W| direction must be specified for globes that measure longitude westward. For celestial coordinates, use {{Sky}} instead.
source:S
Specifies, where present, the data source and data source format/datum, and optionally, the original data, presented in parentheses. This is initially primarily intended for use by geotagging robots, so that data is not blindly repeatedly copied from format to format and Wikipedia to Wikipedia, with progressive loss of precision and attributability.
Examples:
- A lat/long geotag derived from an Ordnance Survey National Grid Reference NM 435 355 found in the English-language Wikipedia would be tagged as "source:enwiki-osgb36(NM435355)"
- A latitude-longitude location sourced from data taken from the German-language Wikipedia would be tagged as "source:dewiki" – and so on, for other language codes;
- A location sourced from the public domain GeoNet Names Server database would be tagged as "source:GNS". No datum or format information is needed, since by default all Wikipedia coordinates are in latitude/longitude format based on the WGS84 datum. Similarly, US locations sourced from the similar public domain GNIS database would be tagged as "source:GNIS".
Per-user display customization
To always display coordinates as DMS values, add this to your common.css:
.geo-default { display: inline }
.geo-nondefault { display: inline }
.geo-dec { display: none }
.geo-dms { display: inline }
To always display coordinates as decimal values, add this to your common.css:
.geo-default { display: inline }
.geo-nondefault { display: inline }
.geo-dec { display: inline }
.geo-dms { display: none }
To display coordinates in both formats, add this to your common.css:
.geo-default { display: inline }
.geo-nondefault { display: inline }
.geo-dec { display: inline }
.geo-dms { display: inline }
.geo-multi-punct { display: inline }
If CSS is disabled, or you have an old copy of MediaWiki:Common.css cached, you will see both formats. (You can either clear your cache or manually refresh this URL: [1].)
To disable display of the blue globe adjacent to coordinates, add this to your common.js:
var wma_settings = {enabled:false}
Note that this will disable WikiMiniAtlas.

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 hidden maintenance category Pages with malformed coordinate tags. There are currently 8 pages in that category. See the category description for further instructions.

Internals
This template is completely powered by the Lua module {{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 sub templates but these have all been replaced by {{Coordinates}}.
Template Data
This template uses overloading[clarification needed] which does not work well with the 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 {{coordDec}} for signed decimal degrees, {{coordDMS}} when degrees minutes and seconds are specified, and {{coordDM}} when just degrees and minutes are given.
TemplateData for Coord
Encodes the latitude and longitude coordinates of a location, provides a link to map of the location. 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. To use this template you will need to use positional parameter following one of these schemes: {{coord | D | M | S | NS | D | M | S | EW | geo | opts}}, {{coord | D | M | NS | D | M | EW | geo | opts}}, {{coord | D| NS | D| EW | geo | opts}} {{coord | sD | sD | geo | opts}} where D is degrees, M is minutes, S seconds, sD signed decimal degrees, NS is N or S, EW is E or W, opts are named parameter and geo are the coordinate parameters described on the main doc page.
