Template:Coord

[edit] [purge] Template documentation

Quick guide

Purpose

This template, {{coord}}, produces a link to a list of map sources, based on the geographical coordinates and other parameters, and provides a standardized notation for, and user-customisable display of, the coordinates.

The template is for WGS84 geographical coordinates (latitude;longitude) on Earth, which can be entered in either decimal notation, or degrees/minutes/seconds parameters, with the appropriate precision. (For non-terrestrial coordinates, see Other globes; for celestial coordinates, use {{Sky}}.)

It links to http://stable.toolserver.org/geohack/geohack.php?pagename=Template:Coord&params=, then displays the coordinates. Clicking the blue globe activates the WikiMiniAtlas (needs Javascript).

The template outputs data in:

• Degree/minutes/seconds ("DMS", precision is degrees, or degrees/minutes, or degrees/minutes/seconds, based on input).
• Decimal (precision by number of decimal places, based on input)
• Geo microformat.

{{coord}} is used by tools which parse the raw Wikipedia database dumps, such as Google Earth. To ensure that the coordinates are parsed correctly by them, display=title must be used. See How do I get my Wikipedia article to show up in the Google Earth Geographic Web layer?. The template must not be modified without prior discussion.

For articles which have no coordinates, but need them, use {{coord missing}}. If the subject's location is unknown or disputed, use {{coord unknown}}.

See also Wikipedia:WikiProject Geographical coordinates.

Superseded templates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}}

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 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=, name= and format=.

• display= can be one of the following:

• display=inline - Display the coordinate inline (default)
• display=title - Display the coordinate near the article title (replaces {{coor title dms}} family), shortcut: display=t
• display=inline,title - Display the coordinate both inline and at title (replaces {{coor at dms}} family)

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. display=title,inline works also. Shortcut: display=it

• 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 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 title coordinates.

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
state	Former country or administrative unit of country, undefined level	1:3,000,000
city(pop)	City, town or village with specified population. Commas will be ignored in pop. There should be no blanks.	1:30,000 ... 1:300,000
city	City, town or village, unspecified population. Will be treated as a minor city.	1:100,000
airport		1:30,000
mountain	peaks, mountain ranges	1:100,000
isle	Isles, islands	1:100,000
waterbody	Bays, fjords, lakes, reservoirs, ponds, lochs, loughs, meres, lagoons, estuaries, inland seas...	1:100,000
forest	Forests and woodlands	1:50,000
river	Rivers and canals	1:100,000
glacier	Glaciers, ice caps	1:50,000
event	One-time or regular events and incidents that occurred on a specific location, e.g. battles	1:50,000
edu	Schools, colleges, universities	1:10,000
pass	mountain passes	1:10,000
railwaystation	stations and stops of railway, train, railroad, metro, rapid transit, underground, subway, elevated railway, etc.	1:10,000
landmark	Cultural landmark, building of special interest, tourist attraction 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

Note: The definition of type:state was changed.

scale:N

The scale: parameter specifies the desired map scale as 1:N, overriding the scales implied by any dim: and type: parameters.

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 (in meters) of a viewing circle centered on the coordinate. GeoHack uses dim: to select a map scale such that the viewing circle appears roughly 10 cm in diameter on a 72 dpi computer monitor.

If scale: is set, it overrides any dim: setting.

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. For example:

AQ Antarctica AU Australia BR Brazil CA Canada CH Switzerland DE Germany DE-TH Thuringia FR France

GB United Kingdom GB-BIR Birmingham IN India LK Sri Lanka NL Netherlands NO-03 Oslo, Norway US United States US-NY New York

In addition, two user-assigned code elements can used with {{coord}}:

• XZ for objects in/above international waters (similar to UN/LOCODE)
• ZZ for use in samples

globe:G

The globe: parameter specifies the planet, dwarf planet, or natural satellite upon which the coordinates reside. Apart from earth (the default), legal 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.

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".

Display

By default coordinates are displayed in the format in which they are specified.

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

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 Coord template needing repair. There are currently 5 pages in that category. See the category description for more information.

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

Internals

See Template:Coord/doc/internals and Category:Coord template.

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/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/prec dec}}	selects a format for converting decimal degrees, based on the precision of the inputs
{{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/display/inline}}	displays coordinates inline
{{Coord/display/title}}	displays coordinates above the article (generally to the right of the article's title)
{{Coord/display/inline,title}}	displays coordinates inline and above the article

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.
