If you have the gps coordinates, just tell them over the phone as you
make the call. They will use it if they have gps eqipment, which is
likely. Automating this seems dangerous in that your SMS to the
emergency service is delayed by a few minutes as the phone struggle to
get the first fix. When you talk, you can fall back on other
descriptions of the place (addresses, road names) if coordinates aren't
