The Geolocation API is ideally suited to web applications for mobile devices such as smartphones. On desktop computers, the W3C Geolocation API works in Firefox since version 3.5, Google Chrome, [6] Opera 10.6, [7] Internet Explorer 9.0, [8] and Safari 5. On mobile devices, it works on Android (firmware 2.0+), iOS, Windows Phone and Maemo.
Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) [5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.
In order to integrate geotags in social media and enhance text readability or oral use, the concept of 'meetag' or tag-to-meet has been proposed. Differing from hashtag construction, meetag includes the geolocation information after an underscore. A meetag is therefore a word or an unspaced phrase prefixed with an underscore ("_").
Location information can also be added to photos, for example via its Exif specification that has fields for longitude/latitude, even if no GPS device was present when the photo was taken. The information can be entered by directly giving the coordinates or by selecting a location from a map using software tools.
Mozilla Location Service (MLS) was an open geolocation service that allowed devices to find their position by processing received signals of publicly observable radio transmitters: cellular network antennae (and their Cell IDs), Wi-Fi access points (and their BSSIDs), and Bluetooth beacons.
A few cameras have built-in geolocation capability. Most, apart from smartphones , do not, so many photographers rely on external GPS receivers to determine location. Location may be inserted immediately into the picture file by tethering with Bluetooth or suitable wired connection, which are about as rare in cameras as the built-in ...
ExifTool is a free and open-source software program for reading, writing, and manipulating image, audio, video, and PDF metadata.As such, ExifTool classes as a tag editor.It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application.
Geomessaging is a technology that allows a person or system to send a message based on any media to a device that enters or exits one or more regions. [1] Those regions can be created by using geofences, based on Latitude and Longitude, or adding beacons to the system associating those beacons with named locations.
