GeoSMS is a specification for geotagging SMS messages.[1][2] It works by embedding locations in the message text, where the locations are formatted as 'geo' URIs as defined in RFC 5870.[3]
It was developed in 2010 by Matthew Kwan, a PhD Candidate at the RMIT School of Mathematical and Geospatial Sciences and should not be confused with the Open GeoSMS standard.
Examples
edit
A simple geotagged SMS might look like:
I'm at the pub geo:-37.801631,144.980294;u=10
which would contain the message I'm at the pub and a location with latitude 37.801631 degrees south, longitude 144.980294 degrees east, and an uncertainty of ( or -) 10 metres.
Messages using GeoSMS can also contain multiple locations, for example:
I'll be at the pub geo:-37.801631,144.980294;u=10 until midnight, then heading to a gig geo:-37.864225,144.97294
which contains two locations.
Applications
editGeoSMS is used by the free Android application I Am Here (available through the Google Play) to send and receive geotagged SMS messages. It displays received messages using either a compass or map view. The GeoSMS specification is also being used to allow ships and cruising vessels to send position updates from an SMS-capable satellite phone, such as one of the recent models marketed by Iridium Communications or Globalstar.[4]
Open GeoSMS
editThe Open Geospatial Consortium also has an approved Open GeoSMS standard, published in 2011. This standard has been broadly implemented in Asia.[citation needed] The OGC Open GeoSMS standard was originally developed in Taiwan by ITRI in 2008 and submitted into the OGC in 2009.
