The OGC Open GeoSMS standard defines an encoding for location enabling a text message to be communicated using a Short Messages System (SMS) which could be applied in emergency cases.

The function of this (compared to toher standards quite small) OGC Open GeoSMS encoding standard is to facilitate communication of location content using the extended Short Message Service feature between different LBS (Location-Based Service) devices or applications for achieving interoperable communications while still maintaining human readability of the content. Namely, any application or service can simply leverage an extended SMS message using the Open GeoSMS format.
