Quick guide

Quick how to
To add 57°18′22.5″N 4°27′32.7″W to the top of an article, use {{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 44.112°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 ("_"): dim: dim:N (viewing diameter in metres) region: region:R (ISO 3166-1 alpha-2 or ISO 3166-2 code) type: type:T (landmark or city(30,000), for example) 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.

• 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}}.

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 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—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.

Logged-in users can 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 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 {{coor d}}, (and others in that family which have since been redirected to it), plus the Geolinks and Mapit templates. Most parameters can be used as before – see Usage.

Examples:

{{coord|10.2|N|-20.3|E|type:city}}	Replaces {{coor d|10.2|N|-20.3|E|city}}
{{coord|44.4|-111.1|type:city_region:US|display=inline,title}}	Replaces {{Geolinks-US-cityscale|44.4|-111.1}}
{{coord|51.01234|-1.56789|type:landmark_region:GB|display=inline,title}}	Replaces {{Geolinks-UK-buildingscale|51.01234|-1.56789}}
{{coord|-35.5|150.1|type:landmark_region:AU|display=inline,title}}	Replaces {{Mapit-AUS-suburbscale|lat=-35.5|long=150.1}}
{{coord|12|34|12|N|45|33|45|W|display=title}}	Replaces {{CoorHeader|12|34|12|N|45|33|45|W}}

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 (replaces {{coor title dms}} family)
  • shortcut: display=t
• display=inline,title – Display the coordinate both inline and beside the article's title (replaces {{coor at dms}} family)
  • 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.

• 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.

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.

Examples

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
country	(e.g. "type:country")	1:10,000,000
satellite	geo-stationary satellites	1:10,000,000
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
city(pop)	cities, towns, villages, hamlets, suburbs, subdivisions, neighborhoods, and other human settlements (including unincorporated and/or abandoned ones) with specified population 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 These are treated as minor cities.	1:100,000
airport	airports and airbases	1:30,000

edu	schools, colleges, and universities	1:10,000
pass	mountain passes	1:10,000
railwaystation	stations, stops, and maintenance areas of railways and trains, including railroad, metro, rapid transit, underground, subway, elevated railway, etc.	1:10,000
landmark	buildings (including factories, museums, theatres, and power plants but excluding schools and railway stations), caves, cemeteries, cultural landmarks, geologic faults, headlands, intersections, mines, ranches, roads, structures (including antennas, bridges, castles, dams, factories, lighthouses, monuments, and stadiums), tourist attractions, valleys, and other points of interest	1:10,000
	Default scale: if no type is used or the type is not defined in the geohack extension	1:300,000

Samples

T	Markup	Result
waterbody	{{coord|46|43|N|7|58|E|type:waterbody}}	46°43′N 7°58′E

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 සෙන්ටිමීටර (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 කිලෝමීටර (19 mi).

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:

2;width:50%

Examples of ISO 3166-2 codes:

• NO-03 Oslo, Norway
• DE-TH Thuringia
• US-NY New York state

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.

globe:G

The globe: parameter specifies the planet, dwarf planet, or natural satellite upon which the coordinates reside. Apart from earth (the default), recognized values are: mercury, venus, moon, mars, phobos, deimos, ceres, ganymede, callisto, io, europa, mimas, enceladus, tethys, dione, rhea, titan, hyperion, iapetus, phoebe, miranda, ariel, umbriel, titania, oberon, triton, and pluto.

Stickney Crater	phobos	{{coord|1|N|49|W|globe:phobos}}	1°N 49°W

For globes other than Earth, {{coord}} does not assume a specific reference system (in contrast with Earth's WGS84). Since the template defaults to east longitude, the |W| direction must be specified for globes that measure longitude westward. At the present time, only limited mapping is available for Mars and the Moon and none for other extraterrestrial bodies. 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 a 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, U.S. 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 monobook.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 monobook.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 monobook.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 monobook.js

var wma_settings = {enabled:false}

Note that this will disable WikiMiniAtlas

See also Wikipedia:Manual of Style (dates and numbers)#Geographical coordinates.

Incorrect uses and maintenance category

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 2 pages in that category. See the category description for further instructions.

A more thorough daily report of coordinates needing repair is at tools:~dispenser/view/File viewer#log:coord-enwiki.log.

Subtemplates

The following templates are "subroutines" of {{Coord}}. Separating them out drastically reduces the pre-expand size of {{Coord}}. They shouldn't be invoked directly.

name	function
{{Coord/display/inline}}	displays coordinates inline
{{Coord/display/inline,title}}	displays coordinates inline and above the article
{{Coord/display/title}}	displays coordinates above the article (generally to the right of the article's title)
{{Coord/link}}	generates microformats and link to GeoHack
{{Coord/input/dec}}	reads coordinates in decimal degrees {{coord|12|-12}}
{{Coord/input/d}}	reads coordinates in decimal degrees with directional letters {{coord|12|N|12|W}}
{{Coord/input/dm}}	reads coordinates in degrees/minutes format {{coord|12|12|N|12|12|W}}
{{Coord/input/dms}}	reads coordinates in degrees/minutes/seconds format {{coord|12|12|12|N|12|12|12|W}}
{{Coord/input/ERROR}}	generates error message if the inputs do not match any of the above formats
{{Coord/input/error2}}	generates error message for range checks and such
{{Coord/input/nolat}}	generates error message for missing latitude
{{Coord/negzeropad}}	pads a positive number with trailing zeroes until it matches the precision of a negative number
{{Coord/prec dec}}	selects a format for converting decimal degrees, based on the precision of the inputs

Coordinates in PDF

For generating PDF, printed books, and Open Office export format, two templates are substituted for the regular templates:

• Template:Coord/display/title/Print for {{Coord/display/title}}
• Template:Coord/link/Print for {{Coord/link}}
• Template:Coord/display/inline,title/Print for {{Coord/display/inline,title}}

Samples are available at:

• Help:Books/Feedback/Tests/coord 1
• Help:Books/Feedback/Tests/coord 2

Class names

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

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 mean time, 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 for this template used by TemplateWizard, VisualEditor and other tools. Click here to see a monthly parameter usage report for this template based on this TemplateData.

TemplateData for Coordinates

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.
