Quick guide

Quick how to
To add 57°18′22.5″N 4°27′32.7″W / 57.306250°N 4.459083°W / 57.306250; -4.459083 to the top of an article, use {{Coord}}, thus:
{{Coord|57|18|22.5|N|4|27|32.7|W|display=title}}

These coordinates are in degrees, minutes, and seconds of arc.

To add 44°06′43″N 87°54′47″W / 44.112°N 87.913°W / 44.112; -87.913 to the top of an article, use either
{{Coord|44.112|N|87.913|W|display=title}}

or

{{Coord|44.112|-87.913|display=title}}

These coordinates are in decimal degrees.

  • Degrees, minutes and seconds must be separated by a pipe ("|").
  • Map datum should be WGS84.
  • Avoid excessive precision (0.0001° is <11 m, 1″ is <31 m).
  • Latitude (N/S) must appear before longitude (E/W).
Optional coordinate parameters follow the longitude and are separated by an underscore ("_"):

Other optional parameters are separated by a pipe ("|"):

  • display
    display=inline (the default) to display in the body of the article only,
    display=title to display in the title only, or
    display=inline,title to display in both places.
  • name
    name=X to label the place on maps (default is PAGENAME)

Thus: {{Coord|44.117|-87.913|dim:30_region:US-WI_type:event

|display=inline,title|name=accident site}}

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.

Related page: 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 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 (Erioll world.svg) 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
  • display=inline,title – Display the coordinate both inline and beside the article's title
    • shortcut: display=it
  • display=title,inline has the same effect as display=inline,title
Note: the title 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. 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=dec reformats the coordinates to decimal degrees format.
  • format=dms reformats 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:

T Description Map scale
adm1st Administrative unit of country, 1st level (province, state), see table, e.g. U.S. states 1:1,000,000
adm2nd Administrative unit of country, 2nd level, see table, e.g. county (United States) 1:300,000
adm3rd Administrative unit of country, 3rd level, see table 1:100,000
airport airports and airbases 1:30,000
city(pop) cities, towns, villages, hamlets, suburbs, subdivisions, neighborhoods, and other human settlements (including unincorporated and/or abandoned ones) with known population
Please replace pop with a number. Commas in pop will be ignored. There should be no blanks.
1:30,000 ... 1:300,000
city cities, towns, villages, hamlets, suburbs, subdivisions, neighborhoods, and other human settlements (including unincorporated and/or abandoned ones) with unspecified population

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.

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 10 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 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.

This is the TemplateData documentation for this template used by VisualEditor and other tools; see the monthly parameter usage report for this template.
