I do not use Google Maps, but Osmand. Osmand needs no active connection all the time, and they do not track me like Google does (all the time). For locating my position, I need GPS, which is completely passive, and that is what Osmand does (Ican also store maps indefinetly on my device, whereas Google makes that complicated and also deletes all stored maps if you have not used them for 2 or 4 weeks). Finally, map quality of OSmand is superior to Google. Far superior.

Now, GPS gives you GPS coordinates. Many people are not familiar with the format. What software like the one I linked to does, is translating GPS coordinates into a much easier-to-catch format: instead of long complicated numbers, three words. And that is much easier to store in your memory, and is easier to handle for people not familiar with tech stuff, navigatio and GPS coordinates.

Since in emergencies time can be of the essence, this is a big win for the one in need.

They say the car industry uses this system, Mercedes for example.
