Geotagging, sometimes referred to as Geocoding, is the process of adding geographical identification metadata to various media such as websites, RSS feeds, or images and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though it can also include altitude, bearing, and place names. For other uses, see Geocoding (disambiguation). ...
Metadata is data about data. ...

This article is about the geographical term. ...
Longitude is the east-west geographic coordinate measurement most commonly utilized in cartography and global navigation. ...
See Cartesian coordinate system or Coordinates (elementary mathematics) for a more elementary introduction to this topic. ...
Altitude is the elevation of an object from a known level or datum. ...
In navigation, a bearing is the clockwise angle between a reference direction (or a datum line) and the direction to an object. ...
Geocoding also refers to the process of taking non-coordinate based geographical identifiers, such as a postal address, and assigning geographic coordinates to them (or vice versa). This article is about longitude and latitude; see also UTM coordinate system Map of Earth showing lines of latitude (vertically) and longitude (horizontally); large version (pdf) The geographic (earth-mapping) coordinate system expresses every horizontal position on Earth by two of the three coordinates of a spherical coordinate system which...
Geotagging can help users find a wide variety of location-specific information. For instance, one can find images taken near a given location by entering latitude and longitude coordinates into a Geotagging-enabled image search engine. Geotagging-enabled information services can also potentially be used to find location-based news, websites, or other resources.[1] A search engine is an information retrieval system designed to help find information stored on a computer system. ...
Web sites
Geotagging HTML web pages is done with meta tags. The GeoURL standard requires the ICBM tag: HTML, an initialism of HyperText Markup Language, is the predominant markup language for web pages. ...
Meta elements are HTML or XHTML elements used to provide structured metadata about a web page. ...
The form used to register a site with the Usenet mapping project before the day of pervasive Internet included a blank for longitude and latitude, preferably to seconds-of-arc accuracy. ...
<meta name="ICBM" content="50.167958, -97.133185"> The similar Geo Tag format allows the addition of placename and region tags: <meta name="geo.position" content="50.167958;-97.133185"> <meta name="geo.placename" content="Rockwood Rural Municipality, Manitoba, Canada"> <meta name="geo.region" content="ca-mb">
Microformat The Geo microformat allows coordinates within Web pages to be marked up in such a way that they can be "discovered" by software tools. Example: This button indicates the presence of a Geo microformat on a page A Geo microformat, detected on the Wikipedia page for Great Barr, by Firefoxs Operator extension. ...
<span class='geo'> <span class='latitude'>50.167958</span>; <span class='longitude'>-97.133185</span> </span> which might display as: 50.167958; -97.133185 (and gives a live Geo microformat on this page). Microformat logo A microformat (sometimes abbreviated μF or uF) is a web-based[1] data formatting approach that seeks to re-use existing content as metadata, using only XHTML and HTML classes[2] and attributes. ...
A proposal has been developed[2] to extend Geo to cover other bodies, such as Mars and the Moon. Adjectives: Martian Atmosphere Surface pressure: 0. ...

An example is the Flickr photo-sharing Web site, which provides geographic data for any geocoded photo in all of the above-mentioned formats. Flickr is a photo sharing website and web services suite, and an online community platform, which is generally considered an early example of a Web 2. ...

Geotagging in tag-based systems No industry standards exist, however there are a variety of techniques for adding geographical identification metadata to an information resource. One convention, established by the Web site called GeoBloggers, encourages users to add tags to their Flickr images and del.icio.us bookmarks, enabling them to be found via a location search. Both Flickr and del.icio.us allow users to add metadata to an information resource via a set of tags (see folksonomy). Flickr is a photo sharing website and web services suite, and an online community platform, which is generally considered an early example of a Web 2. ...
The website del. ...
A folksonomy is a user-generated taxonomy used to categorize and retrieve web content such as Web pages, photographs and Web links, using open-ended labels called tags. ...
The convention established by GeoBloggers uses three tags to geotag an information resource:
- geotagged
- geo:lat=latitude e.g. geo:lat=51.4989
- geo:lon=longitude e.g. geo:lon=-0.1786
where latitude and longitude are the geographic coordinates of a particular location. These are expressed in decimal degrees in the WGS84 datum, which has become something of a default geodetic datum with the advent of GPS.[citation needed] This article is about the geographical term. ...
Longitude is the east-west geographic coordinate measurement most commonly utilized in cartography and global navigation. ...
WGS 84 is the 1984 revision of the World Geodetic System. ...
Over fifty GPS satellites such as this NAVSTAR have been launched since 1978. ...
Using three tags works within the constraint of having tags that can only be single 'words'. Identifying geotagged information resources on sites like Flickr and del.icio.us is done by searching for the 'geotagged' tag, since the tags beginning 'geo:lat=' and 'geo:lon=' are necessarily very variable.
A further convention proposed by FlickrFly adds tags to specify the suggested viewing angle and range when the geotagged location is viewed in Google Earth: Google Earth is a virtual globe program that was originally called Earth Viewer and was created by Keyhole, Inc. ...
- ge:head=xxxx e.g. ge:head=127.00, where xxxx is the view heading in decimal degrees (0-360) where zero is looking North.
- ge:tilt=yyyy e.g. ge:tilt=60.00, where yyyy is the view tilt angle in decimal degrees, where 0 is looking straight down and 90 is looking horizontally from ground level.
- ge:range=zzzz e.g. ge:range=560.00, where zzzz is the range of the viewpoint in metres from the marker location.
metre or meter, see meter (disambiguation) The metre is the basic unit of length in the International System of Units. ...
GeoTagging in Specific Systems In August 2006, Flickr introduced support for geographic information in the picture properties and its interface[3], deprecating the Geobloggers method. Flickr is a photo sharing website and web services suite, and an online community platform, which is generally considered an early example of a Web 2. ...

Geoblogging Geoblogging attaches specific geographic location information to blog entries via geotags. Searching a list of blogs and pictures tagged using geotag technology allows users to select areas of specific interest to them on interactive maps.[citation needed] To meet Wikipedias quality standards, this article or section may require cleanup. ...
