Template:Coord/doc

Purpose
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. 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.

See also 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  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  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)
 * 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 in 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Superseded templates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:

Usage
&#123;{coord|latitude|longitude|coordinate parameters|template parameters}&#125; &#123;{coord|dd|N/S|dd|E/W|coordinate parameters|template parameters}&#125; &#123;{coord|dd|mm|N/S|dd|mm|E/W|coordinate parameters|template parameters}&#125; &#123;{coord|dd|mm|ss|N/S|dd|mm|ss|E/W|coordinate parameters|template parameters}&#125;

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 the coordinate inline (default)
 * – Display the coordinate near the article title (replaces coor title dms family)
 * shortcut:
 * – Display the coordinate both inline and at title (replaces coor at dms family)
 * shortcut:
 * has the same effect as
 * Note: the  attribute indicates that the coordinates apply to the entire article, and not just one of (perhaps many) places mentioned in it &mdash; so it should only be omitted in the latter case.
 * format= can be used to force dec or dms coordinate display.
 * reformats the coordinates to decimal degrees format.
 * 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.

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 is/are currently  page(s) in that category. See the category description for further instructions.

A daily report of coordinates needing repair is at ~dispenser/view/File viewer.

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.
