WikiProject Geographical coordinates aims to better organize location information in articles containinga set of numbers that identifies location on and relative to the Earth. In particular, we aim to establish a standard for uniform handling oflatitude andlongitude coordinates as given in various Wikipedia articles, somewhat analogous to howISBN numbers are handled.

WikiProject Council includes this WikiProject in itsGeographical directory. This WikiProject is an offshoot of WikiProject Maps:
...and is the parent project of:
Other WikiProjects that make use of geographical coordinates include:
The AtlasPortal is associated with WikiProject Geography.
The Geography Portal is associated with WikiProject Geography.
This list has been moved toits own page.
In general, coordinates should be added to any article about a location, structure, or geographic feature that is more or less fixed in one place. Such items can vary in size from a single tree (or smaller) to entire oceans or continents. Coordinates should also be added to articles about events that are associated with a single location, for example, theUfa train disaster. Guidelines for less obvious situations are given below.
Coordinates are appropriate for the top articles or within infoboxes of the following types of articles:
Do not add coordinates to the following types of articles:
Other types of articles may be decided on a case-by-case basis.
National mapping agencies such as theGeographic Names Information System (GNIS),Ordnance Survey (OS), andGeographical Names Board of Canada (GNBC) are usuallyreliable sources for coordinates. TheGEOnet Names Server (GNS) database is not reliable. Always double check the coordinates on an internet mapping service. For other locations, the following points should be considered:
The practical usage of coordinate markup in Wikipedia is described inthe style guide for geographical coordinates. For use on maps and other services,parameters may also be required.
A complete entry could for example be:{{coord|51|28|40|N|0|0|6|W|type:landmark_scale:2000_region:GB|display=title}}

There are two ways of specifying coordinates:
{{coord}} – Accepts multiple data formats and supports a style sheet preference for display format, plus aGeo microformat.Coord may be placed anywhere in the article source text, inline, with prose text. For example "Mount Everest is at {{coord|27|59|16|N|86|56|40|E}}", which displays as "Mount Everest is at27°59′16″N86°56′40″E / 27.98778°N 86.94444°E /27.98778; 86.94444". To display coordinates at the page's top, near the article's title, in a skin-dependent way, usedisplay=title (see example atKrasnoyarsk hydroelectric dam). To display both inline and top, usedisplay=inline,title.|coordinates=, for specifying a place's coordinates. The template internally uses{{coord}} and may therefore also display in the title area. SeeTemplate:Infobox Settlement andTemplate:Infobox Mountain for documentation, or, usage examples atLos Angeles andMount Everest.(Before September 2008, there was a widely-used family of templates of the formcoor .... These are deprecated and have been replaced by{{coord}}. For an overview of choices:WikiProject Geographical coordinates/comparison.)
Following the geographical coordinate, further parameters can optionally be supplied, separated by underscores. This helps display suitable map resources (seeTemplate:GeoTemplate), and will helpWikimaps become fully functional.

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[update].
The maps roughly imply a coordinate reference system, but do 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.
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:
{{coord}} takes|name=name
If an article contains severaldisplay=inline coordinates, each of these may be supplied with a uniquename. This name will be used to display the coordinate on theWikiMiniAtlas, and will cause the template to emit anhCardmicroformat 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.
To always display coordinates as DMS values, add this toyour 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 toyour 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 toyour 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 ofMediaWiki: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 toyour common.js:
varwma_settings={enabled:false}
Note that this will disableWikiMiniAtlas.
See also:Wikipedia:Manual of Style/Dates and numbers § Geographical coordinates.
format=dec will reformat the coordinates todecimal degrees for all readers.format=dms will reformat the coordinates todegrees | minutes | seconds (dms) format for all readers.When creating new templates or infoboxes, use{{coord}}. Unless a template uses the coordinate data in another way, the{{coord}} template should be the field value. For example,{{infobox lake}} acceptscoords = {{coord|45|N|6|E|type:waterbody}}.
If coordinate data are used directly by a template, use the following parameter names for coordinates:
|
|
A provision for accepting decimal coordinates is recommended. For example, allowlat_d = 45.678 | long_d = -123.456 and omission of the remaining parameters.
Where theUnited Kingdom'sOrdnance Survey grid references are used as the coordinates, use{{oscoor}}.
For articles which have no coordinates, but need them, use{{coord missing}}.
Fordraft guidance on, and examples of, coordinates for linear features (rivers, roads, bridges, tunnels, etc.), seeWikipedia:WikiProject Geographical coordinates/Linear.
SeeObtaining geographic coordinates
See also:Category:Articles needing coordinates,Maybe-Checker
All coordinates specified through{{coord}} must be referenced toWGS84, or an equivalent datum. WGS84 is required for some of the conversions done by the geohack extension.
British national grid references of the Ordnance Survey use its ownOSGB36 datum, which iscorrect for use in national grid references; the correct transformations will automatically be applied when national grid coordinates are used in{{oscoor}} tags. However, OSGB36 latitude/longitude coordinates should not be used anywhere in Wikipedia; please use WGS84 lat/long instead.
Regardless of how coordinates are obtained, consider the precision specified in a Wikipedia article. Reliable secondary sources exist for some locations.Without a reliable source, the larger the object being mapped, the less precise the coordinates need to be. Cities must be specified with a precision of degrees, minutes and seconds to respect historical norms. When the#Which coordinates to use guideline is used, degrees, minutes and seconds or d.dddd are the default. To specify a particular point in the city, such as a building, generally requires precision down to degrees-minutes-seconds or d.dddd° if decimal degrees are used. In the case of objects such as fountains or statues, it may be necessary to use d°m's.s" or d.ddddd°. Higher precisions should be avoided, as they greatly exceed the accuracy of civilian GPS and online mapping services. (Using 4 m accuracy as an estimate for civilian GPS: Depending on the coordinates format and the latitude, the next-higher precisions exceed the accuracy by a factor of somewhere between 13 and 72.)
A general rule is to give precisions approximately one-tenth the size of the object, unless there is a clear reason for additional precision. Overly precise coordinates can be misleading by implying that the object is smaller than it truly is.
There is no set way to determine object size, and the boundaries of many geographical objects are not clearly defined or not readily available. The difference rarely affects the suggested coordinates precision, so a rough size estimate is usually adequate. However, it should be noted that object size is always linear (one-dimensional), not an area measurement.
In the two most-used coordinate representations, degrees-minutes-seconds and decimal degrees, precision is, as a useful approximation,

Conversions: 1 kilometre (0.621 mi), 1 metre (3.28 ft), 1 centimetre (0.394 in);1 mile (1.61 km), 1 foot (0.305 m), 1 inch (2.54 cm)
The values in the table give distances in the east-west direction corresponding to a small change in longitude, at different latitudes. You can take the equator columns of the table as a rough guide to distances in the north-south direction that correspond to a small change in latitude, since they vary only a little bit at different latitudes. For simplicity, however, the latitude precision is commonly copied from that of the longitude.
The following tables show suggested coordinates precisions for various object sizes and latitudes. Refer to the preceding section for more information about coordinates precision. To use these tables:
The colors on the table serve only to distinguish consecutive precision levels.
Usage example |

Example: You want coordinates, in decimal degrees format, for Yosemite National Park, California, U.S.
To solve:
(This is a good example of aborderline case, as the latitude is quite close to 37.5°, the midpoint between 30° and 45°. If the Park were a mere 25 miles to the south, you would use the30° column instead, yielding a different precision: d.dd°. You could opt for that precision instead, giving 37.85, −119.56. That's your call. But the table shows thatmore than two decimal positions would definitely be too precise for this case.) |

Articles (and coordinates) can be found through the pages using the templates inCategory:Coordinates templates
All coordinates are available for download inWikipedia database dumps. To get the coordinates from theXML format dump of all articles (enwiki-latest-pages-articles.xml.bz2, 4 GB), the dump needs to beparsed for pages containing coordinates in theentry formats listed above. Most articles in Wikipedia conform to these formats and coordinates are easy to parse from thewikitext withregular expressions for simple character sequences. As all coordinates link tothe same PHP tool, they may also be found from theSQL formattable of external links (enwiki-latest-externallinks.sql.gz, 725MB). This second method will however not include all available information about the coordinates, such as their position between the article body and the title area.
There may exist some groups of articles that generate the coordinate data dynamically and are not in any of the standard entry formats, as some editors may have wished to facilitate entry of common coordinate related information, while only keeping the output similar with the existing templates. To get all such coordinates, all the articles in the database dump need to be run through a wikitext parser (such as thePHP one inMediaWiki) to expand all the templates, and the result parsed for coordinates. Alternatively, it is also possible to download the HTML generated from all the article and expanded template content (wikipedia-en-html.tar.7z, 14 GB).
Note that mass downloading individual pages from the live Wikipedia site is strongly discouraged andmay lead to discontinued access.
All examples useNASA World Wind, with the Wikipedia overlay. This is purely meant as an example of using a coordinated concept for geographical coordinates.

WikiMiniAtlas is a JavaScript to add to yourmonobook.js. It adds a draggable and zoomable (just like GoogleMaps) map to all geo-coded articles. Clickable labels with links to other geocoded articles are placed on the map to allow spatial browsing of Wikipedia. Map layers includesatellite images (using Landsat7 data) with zoomlevels down to a resolution <100m, anddaily updated MODIS satellite data.
WikiMiniAtlas is currently enabled on Wikipedia (by clicking on the globe (
) beside the coordinates).
Kmlexport tool: Pages marked with multiple coordinates or categories of articles with coordinates can be exported asKML (for use in Google Earth, for example). This tool and some alternatives can be found on clicking the coordinates or by applying the{{GeoGroup}} template on a page.
The Kmlexport can be used directly or through Google Maps; see for exampleColmar Pocket orCategory:Capitals in Europe. Export from articles is real-time, export from categories is based on stored extractions (may be several weeks old).
KML may be converted in other formats, suitable asPoints of Interest (POI) forGPS systems.
