Google map is one of the popular and top most used product.
It offers satellite imagery, street maps, Street View(in some countries only), real-time traffic conditions(Google Traffic), and route planning for travelling by foot, car or public transportation.
Google map was launched on 2005 after acquisition of Keyhole and ZipDash in 2004.
I am using google map for many years by now and since when I have android phone in my hand I am a regular user of google map.
A very intelligent application or a product or service whatever it is, its serve my intentions.
Whenever I have to go a new place or a place which I visited before many years and dont remembered the path to go there. I use google map on my smart phone to find out how to reach there, with using option, whether I am using public transport or driving a car or I have to go there on foot.
In around November 2009, google released Navigation in conjunction with Google Android OS 2.0 Eclair on the Motorola Droid, adding voice commands, traffic reports, and street view support.
Navigation notice your current location with help of GPS and guide you through out the journey. Which also needs internet connectivity in your phone.
When I was on the way of Mahabaleshwar feaw months back with my friend unknown to route, we have used its Navigation function to reach there. But whenever Network was weak or no network, Navigation also stops working, which confused use many times, but finally with its help we reached there.
While using public transport, it also guides you which bus to board in, from where to board in.
Google map also gives a satellite view of the earth, though due to security concerns, some places have been colored like rooftop of White House.
3 years back in 2012 Apple announced it apple map which will replace google map, but after it uses user found discrepancies and due to incorrect mapping people lost there ways.
IT iS THE BEST.!
