to the top of an article, use
{{
Coord
}}, thus:
{{Coord|57|18|22|N|4|27|32|W|display=title}}
These
coordinates
are in
degrees
,
minutes
, and seconds of arc.
'title' means that the coordinates will be displayed next to the title.

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
must be WGS84 (except for off-earth bodies).
- 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 at the top of the article 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}}
Use
|display=title
(or
|display=inline,title
) once per article, for the subject of the article, where appropriate.

{{
Coord/doc
}}.

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
}}.

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 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.
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

The hemisphere identifiers (

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)
display=inline,title
? Display the coordinate both inline and beside the article's title (replaces
{{
coor at dms
}} family)
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.
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).
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.

UN/LOCODE
).
- ZZ
for use in examples.
globe:

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

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
0
pages in that category. See the category description for further instructions.

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.
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.
