Non-rhetorical question: who has to remember it and why?

Is this primarily a work-around for the problem of it not being possible for a mobile phone handset to display the location during a voice call? If so, maybe someone should fix that problem because there might be other things that the caller might want to refer to on the screen while calling.

It's slightly hilarious, in a way. I can imagine a conversation with the inventor: How much memory does a typical phone have? And you're telling me that we should use this proprietary system for encoding coordinates so that the user can more easily memorise the coordinates? Tell me, do you use a similar system for memorising your friends' telephone numbers?

Of course in the case of emergency calls it really should not be beyond the wit of man to implement a system so that the owner of a phone can configure it to automatically send its location to the other party when an emergency call is initiated. I'm fairly privacy-conscious but I'd probably enable that one.
