MY LATITUDE LONGITUDE

Real-time identification of location expressed in terms of latitude and longitude, abbreviated as "Lat/Lon", can now be found in many mass marketed devices such as GPS receivers and cell phones... Search and rescue has long used Latitude and Longitude. A boater, hiker, climber, etc., is well advised to call for help with current Lat/Lon in hand. Advanced marine radios with digital selective calling can automatically transmit Lat/Lon in emergency broadcasts. Expect such function to migrate to all new marine radios and to ubiquitous devices such as cell phones.
