وکیپیڈیا:WikiProject Geographical coordinates
WikiProject Geographical coordinates aims to better organize location information in articles containing a set of numbers that identifies location on and relative to the Earth. In particular, we aim to establish a standard for uniform handling of latitude and longitude coordinates as given in various Wikipedia articles, somewhat analogous to how ISBN numbers are handled.

Goals
سودھو- Should provide a uniform markup for all geographic coordinates
- Should provide a user-preferred appearance for all geographic coordinates
- Markup should be easy and natural to use
- 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
- 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.
- 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).
- Serve as a tool for finding Wikipedia articles describing nearby locations. See also meta:Wikipediatlas.
- Adhere to existing Internet standards for geographic coordinates as far as possible
Usage guidelines
سودھوسانچہ:WikiProject style advice
- See also
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, the Ufa 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:
- Businesses/organizations with a single location (even if they are defunct)
- Demolished buildings/structures
- Buildings/structures that have been proposed, but not yet built (if there is a reliable source for the location)
- Permanently docked ships (and shipwrecks)
Do not add coordinates to the following types of articles:
- Biographies of living people
- Works of art (other than permanent statues or murals)
- Sports teams (add to the stadium article instead)
- Businesses with multiple locations (although listing coords for individual locations in a table may be appropriate)
- Ships that are not permanently docked or sunk
Other types of articles may be decided on a case-by-case basis.
Which coordinates to use
سودھوNational mapping agencies such as the Geographic Names Information System (GNIS), Ordnance Survey (OS), and Geographical Names Board of Canada (GNBC) are reliable sources for coordinates. The GEOnet 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:
- For villages, towns, communities, etc., 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.
Markup
سودھوThe 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|display=title}}
See also: Obtaining coordinates
Marking project-related pages on Talk page
سودھوThe template {{WikiProject Geographical coordinates}} may be added to relevant Talk pages. This adds the page to several categories and displays as: سانچہ:WPBannerMeta
Implementation details
سودھوCoordinate templates
سودھوThere are two ways of specifying coordinates:
{{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". 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
.
- 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
سودھوFollowing 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.

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
سودھوSpecifies, 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 preferences
سودھوTo 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: [۱].)
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.
See also Wikipedia:Manual of Style (dates and numbers)#Geographical coordinates.
Format
سودھوformat=dec
will reformat the coordinates to decimal degrees for all readers.format=dms
will reformat the coordinates to degrees | minutes | seconds (dms) format for all readers.
Creating new templates
سودھو{{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:
|
|
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
سودھوFor 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
سودھوSee Obtaining geographic coordinates
See also: Category:Articles needing coordinates, Maybe-Checker
Geodetic system
سودھو{{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 guidelines
سودھوRegardless 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,
|
|
Conversions: ۱ کلومیٹر (۰٫۶۲۱ میل), ۱ میٹر (۳٫۲۸ فٹ), ۱ سینٹیمیٹر (۰٫۳۹۴ انچ); ۱ میل (۱٫۶۱ کلومیٹر), ۱ فٹ (۰٫۳۰۵ میٹر), ۱ انچ (۲٫۵۴ سینٹی میٹر)
The values in the table give distances in the east-west direction corresponding to a small change in longitude, at different latitudes. You can also 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.
You can also calculate the kilometers per degree of longitude using one of the following approximation formulas (θ is the latitude in degrees, 6378 km is the equatorial radius, and 6357 km is the polar radius):
Best:
Better:
Sufficient:
Precision tables
سودھوThe 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:
- Choose one of the tables depending on whether you want degrees-minutes-seconds format or decimal degrees format
- Find the column that is closest to the latitude of your object
- Find the row that is closest to the size of your object
- Note the coordinates precision at the intersection of your row and column
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 a borderline 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 the 30° 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 that more than two decimal positions would definitely be too precise for this case.) |
|
|
- The tables are derived from the precision data at سانچہ:Section link, above. As suggested there, they use a target resolution of one-tenth of the object size.
- The tables are not perfect. Some cases will yield a precision that is different from what you would get by doing the math (including trigonometry) for that specific case. This is because it is impossible to represent all cases correctly in a usable tabular format. The tables provide the correct precision for a majority of cases. Any error should be limited to one level of precision (e.g., d° m' vs. d° m' s", or d.ddd° vs. d.dddd°), which is acceptable for the purposes of Wikipedia coordinates.

To do list
سودھوTools and applications based on coordinates from Wikipedia
سودھوArticles (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.

In September 2009, the milestone of half a million articles with geocoordinates had been reached (see Signpost coverage). In related news, links to display interactive OpenStreetMap maps within articles were recently enabled by default on the German and Norwegian (Bokmål/Rikmål) Wikipedias (to see an example, click "Karte" on the top right of de:Berlin), the fruit of a collaboration that had been begun last year, supported by the German Wikimedia chapter (see Signpost coverage)."
