Google Maps let you know which road is one way, where is no parking and where you can park your vehicle. You can also see the actual shapes or height of the building. This is done by capturing the images from the airplane to provide the 3D view of your town.
Google tries to provide the details about the shops in yellow pages but the owners of the shop start approaching Google themselves to provide the details like timing, their contact details etc. So this listing we can see easily. Google Maps also provides internal mapping of some buildings like malls, airports.
We also provide some data to Google Maps. Some people provide the street view of their Gully where Google can’t reach and also give information about the crowd.
Due to our location services on the phone Google tells where there is traffic jam or which place is crowded.
If a new lane is constructed and so Google doesn’t know about it but when people start using this lane Google can observe the movement on that particular place through our mobile phone location services and then list that place. By compiling all this detail, we can use it easily.
