Google map is like a way. From Google maps, we can go anywhere in the world. Google maps is gone by satellite. Google maps tell us, how far distance from here and buses, trains have traveled or not. How many kilometers from this to that place. Google maps works by net if net is not available then we can not find any place.
You can make reservations at participating restaurants within Google maps. The apps of Google maps is download in my mobile phone. I also check, if I have to go anywhere.
Thank you Google maps developer.
You are amazing searcher.
