Any Wikipedian may participate in this project to better organize information in articles containing geographical coordinates. This page and its subpages contain suggestions; it is hoped that this project will help to focus the efforts of other Wikipedians. If you would like to help, please include yourself as participant, inquire on the talk page and see the to-do list there.

NOTE: This is a concept currently under development, so this is subject to change.

Quick how-to

To add 57°18′22″N 4°27′32″W / 57.30611°N 4.45889°W / 57.30611; -4.45889 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 article's title at the top of the page (in desktop view only; title coordinates do not display in mobile view) and before any other text or images. It also records the coordinates as the primary location of the page's subject in Wikipedia's geosearch API.

To add 44°06′45″N 87°54′47″W / 44.1124°N 87.9130°W / 44.1124; -87.9130 to the top of an article, use either

{{Coord|44.1124|N|87.9130|W|display=title}}

(which does not require minutes or seconds but does require the user to specify north/ south and east/west) or

{{Coord|44.1124|-87.9130|display=title}}

(in which the north and east are presumed by positive values while the south and west are negative ones). These coordinates are in decimal degrees.

  • Degrees, minutes and seconds, when used, must each be separated by a pipe ("|").
  • Map datum must be WGS84 if possible (except for off-Earth bodies).
  • Avoid excessive precision (0.0001° is <11 m, 1″ is <31 m).
  • Maintain consistency of decimal places or minutes/seconds between latitude and longitude.
  • 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 (in desktop view only; title coordinates do not display in mobile view), or
    |display=inline,title to display in both places.
  • name
    name=X to label the place on maps (default is PAGENAME)

Thus: {{Coord|44.1172|-87.9135|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.

  • For a village, use the current centre. Where this is difficult, choose the earliest known settlement of that name.
  • For military and industrial establishments (e.g. castles, barracks, dockyards, car plants) use the main gate.
  • For administrative districts, use the head office.
  • For linear features see Wikipedia:WikiProject Geographical coordinates/Linear.

Userbox: {{User WikiProject Geographical_coordinates}}

Goals

  1. Should provide a uniform markup for all geographic coordinates
  2. Should provide a user-preferred appearance for all geographic coordinates
  3. Markup should be easy and natural to use
  4. ☑.svg Should be able to have a uniform, extensible way of accessing all types of map resources, avoiding having direct external links to maps in articles
  5. ☑.svg Clicking on a reference navigates directly to a page with external pointers to various resources, with coordinates automatically embedded where possible. The resources can be maps of various kinds, topological charts, satellite photos and others.
  6. ☑.svg Create a database of points, enabling generation of navigatable maps with a clickable icon appearing for every location for which there is a Wikipedia article. This has been implemented for NASA World Wind, Google Earth (see below) and Google maps (see below).
  7. ☑.svg Serve as a tool for finding Wikipedia articles describing nearby locations. See also meta:Wikipediatlas.
  8. Adhere to existing Internet standards for geographic coordinates as far as possible

Markup

The practical usage of coordinate markup in Wikipedia is described in the 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}}

See also: Obtaining coordinates

Marking project-related pages on Talk page

The template {{WPcoord}} may be added to relevant Talk pages. This adds the page to several categories and displays as:

Implementation details

Coordinate templates

There are two ways of specifying coordinates:

  1. {{coord}} - Accepts multiple data formats and supports a style sheet preference for display format, plus a Geo 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 at 27°59′16″N 86°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, use display=title (see example at Krasnoyarsk hydroelectric dam). To display both inline and top, use display=inline,title.
  2. Infoboxes - Many infobox templates for places have a field for specifying a place's coordinates. The template internally uses {{coord}} and may therefore also display in the title area. See Template:Infobox Settlement and Template:Infobox Mountain for documentation, or, usage examples at Los Angeles and Mount Everest.

(Before September 2008, there was a widely-used family of templates of the form coor .... These are deprecated and have been replaced by {{coord}}. For an overview of choices: WikiProject Geographical coordinates/comparison.)

Parameters

Following the geographical coordinate, further parameters can optionally be supplied, separated by underscores. This helps display suitable map resources (see Template:GeoTemplate), and will help Wikimaps become fully functional.

For example:

{{coord|61.1631|-149.9721|type:landmark_globe:earth_region:US-AK_scale:150000_source:gnis|name=Kulis Air National Guard Base}} displays 61°09′47″N 149°58′20″W / 61.1631°N 149.9721°W / 61.1631; -149.9721 (Kulis Air National Guard Base)

It has

  • type:landmark
  • globe:earth
  • region:US-AK
  • scale:150000
  • source:gnis
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
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
airport airports and airbases 1:30,000
city(pop) cities, towns, villages, hamlets, suburbs, subdivisions, neighborhoods, and other human settlements (including unincorporated and/or abandoned ones) with known population
Please replace pop with a number. 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
country (e.g. "type:country") 1:10,000,000
edu schools, colleges, and universities 1:10,000

satellite geo-stationary satellites 1:10,000,000
waterbody bays, fjords, lakes, reservoirs, ponds, lochs, loughs, meres, lagoons, estuaries, inland seas, and waterfalls 1:100,000
camera To indicate the location of where a specific image was taken. This type is used by coordinate templates on File pages. 1:10,000
Default scale: if no type is used or the type is not defined in the GeoHack extension 1:300,000

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.

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:

  • AQ Antarctica
  • AU Australia
  • BR Brazil
  • DE Germany
  • GB United Kingdom
  • HK Hong Kong
  • IN India
  • LK Sri Lanka
  • RU Russia
  • US United States

Examples of ISO 3166-2 region codes:

  • DE-TH Thuringia, Germany
  • GB-BIR Birmingham, England
  • NO-03 Oslo, Norway
  • US-NY New York state, US

The oceans have the following Wiki assigned code elements per de:Vorlage:Coordinate#Ozeane.

  • XN Arctic Ocean
  • XA Atlantic Ocean
  • XI Indian Ocean
  • XP Pacific Ocean
  • XS Southern Ocean

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.

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.

The maps roughly implies a coordinate reference system, but does 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.

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 an 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, US locations sourced from the similar public domain GNIS database would be tagged as "source:GNIS".

Display

To always display coordinates as DMS values, add this to your 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 to your 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 to your 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 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 common.js: 

var wma_settings = {enabled:false}

Note that this will disable WikiMiniAtlas.

Format

Template:Coord-doc-format

Creating new templates

When creating new templates or infoboxes, use {{coord}}. Unless a template uses the coordinate data in another way (such as creating a dot on a standard map), the {{coord}} template should be the field value. For example, {{infobox lake}} accepts coords = {{coord|45|N|6|E|type:waterbody}}.

If coordinate data are used directly by a template, use the following parameter names for coordinates:

  • lat_d
  • lat_m
  • lat_s
  • lat_NS
  • long_d
  • long_m
  • long_s
  • long_EW

A provision for accepting decimal coordinates is recommended. For example, allow lat_d = 45.678 | long_d = -123.456 and omission of the remaining parameters.

Where the United Kingdom's Ordnance Survey grid references are used as the coordinates, use {{oscoor}}.

For articles which have no coordinates, but need them, use {{coord missing}}.

Linear features

For draft guidance on, and examples of, coordinates for linear features (rivers, roads, bridges, tunnels, etc.), see Wikipedia:WikiProject Geographical coordinates/Linear.

How to obtain geographical coordinates

See Obtaining geographic coordinates

See also: Category:Articles needing coordinates, Maybe-Checker

Geodetic system

All coordinates specified through {{coord}} must be referenced to WGS84, 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 own OSGB36 datum, which is correct 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.

Precision

Regardless of how coordinates are obtained, consider the precision specified in a Wikipedia article. Generally, the larger the object being mapped, the less precise the coordinates should be. For example, the location of a city can be specified with a precision of 100 meters, or even 1 km. To specify a particular point in the city, such as the central administrative building, or a fountain would justify precisions down to 10 meters or even one meter in some cases.

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 geographic area is smaller than it truly is.

In the two most-used coordinate representations, degrees-minutes-seconds and decimal degrees, precision is, as a useful approximation,

Distances along lines of latitude are the same at the equator but shrink toward the poles. Unless there is specific reason to take this into account, the distances along lines of longitude should suffice as a guide.

You can calculate the number of kilometers per degree of longitude using one of the following approximation formulas (θ is the latitude in degrees):

Coordinates from other language versions (iwcoor)

Import of coordinates from other wikis
  • conversions are done based on external links to mapsources in other languages
  • the iwlog determines primary coordinates for articles in other languages
  • in general, primary coordinates are imported to this wiki
  • coordinates are used to replace {{coord missing}} with {{coord}} with the parameter display=title
  • dms or decimal format is kept, format=dms can be added to decimal coordinates
  • negative coordinates followed by N or E are converted to positive coordinates followed by S or W
  • coordinates are not imported if:
    • degrees are out of range (90°/180°)
    • minutes or seconds >= 60
    • region doesn't start with [a-zA-Z][a-zA-Z]
    • type is not in list. A few are corrected (e.g. village=>city, lake=>waterbody, dam=>landmark, island=>isle). coordinates with type:state are not converted. Numbers other than population are stripped.
    • globe is present
  • scale is kept, zoom from nl: converted to scale. scale can be dropped if it's equivalent to the one determined by type
  • source is set to "xxwiki" (xx being the wiki the coordinates are imported from). An additional string can be added to differentiate one bot from others (e.g. "-x"). If source: is used in the other language, the previous element is added after a slash, e.g. source:gnis imported from xx: wiki => source:xxwiki-gnis
  • region is set to uppercase, type and scale to lowercase
  • other elements are discarded

To do list

Tools and applications based on coordinates from Wikipedia

Articles (and coordinates) can be found through the pages using the templates in Category:Coordinates templates

All coordinates are available for download in Wikipedia database dumps. To get the coordinates from the XML format dump of all articles (enwiki-latest-pages-articles.xml.bz2, 4 GB), the dump needs to be parsed for pages containing coordinates in the entry formats listed above. Most articles in Wikipedia conform to these formats and coordinates are easy to parse from the wikitext with regular expressions for simple character sequences. As all coordinates link to the same PHP tool, they may also be found from the SQL format table 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 the PHP one in MediaWiki) 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 and may lead to discontinued access.

NASA World Wind Samples

All examples use NASA World Wind, with the Wikipedia overlay. This is purely meant as an example of one thing that a coordinated concept for geographical coordinates can be used for.

Links to Wikipedia articles are represented by yellow rings, such as in this view of the Washington DC National Mall, using USGS aerial photos
This view of San Francisco is done using Landsat 7 satellite images. Again, note the rings that indicate Wikipedia articles
Combining radar topographic (Shuttle Radar Topography Mission) data with Landsat-7 images allows full 3D visualization, producing images like this one, of Mount Baker. The upper ring is for the Space Needle. Note also that vertical exaggeration is enabled.

View Wikipedia in Google Earth

Project Wikipedia-World scan 11 Dumps (ca,cs,de,en,eo,es,fi,fr,nl,pt,ru) and provides:

  • dynamic Google-Earth layers in 21 languages. For instance: english Layer
  • static Google-Earth layers in 10 language with different folders (Castles, Parks,...), Download at webkuehn.de
  • SQL-Data off all scanned coordinates

Visualization of Wikipedia articles with Google Maps

  • www.geonames.org over 800,000 Wikipedia articles in 230 languages on Google maps. The placemarks include short descriptions of the displayed items, extracted from the Wikipedia articles. Webservices for full text search and reverse geocoding of wikipedia articles.

WikiMiniAtlas JavaScript plugin

WikiMiniAtlas in action

WikiMiniAtlas is a JavaScript to add to your monobook.js. It adds a draggable and zoomable (just like GoogleMaps) map to all geo-coded articles. Clickable labels with links other geocoded articles are placed on the map to allow spatial browsing of wikipedia. Map layers include satellite images (using Landsat7 data) with zoomlevels down to a resolution <100m, and daily updated MODIS satellite data.

WikiMiniAtlas is currently enabled on Wikipedia (by clicking on the globe () beside the coordinates).

All geodata in SQL file format

Export multiple coordinates

Kmlexport tool: Pages marked with multiple coordinates or categories of articles with coordinates can be exported as KML (for use in Google Earth, for example). This tool and some alternatives can be found on clicking the coordinates or by applying the {{GeoGroupTemplate}} template on a page.

The Kmlexport can be used directly or through Google Maps; see for example Colmar Pocket or Category: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 as Points of Interest (POI) for GPS systems.

Coordinates search tool

tools:~dispenser/cgi-bin/geosearch.py allows for regular expression searching on the GeoHack links in the external links table. This has the advantages of near real time information and powerful pattern matching. The following are some example queries created as a demonstration of the flexibility of the system.
