Being a local guide I get an opportunity to help people. People looking for any place or store can just search for the places in their locality. It not only helps them to locate the place but by seeing the photos and reviews of the place they can decide whether to visit the place or not.
Also, people can view the contact number of stores before booking. These help them to make bookings if required before visiting the store and separates them from the big queue waiting outside the gate for their own chance to enter the place.
The local guide also gives an opportunity to add the missing places on maps. This is the best feature of maps as people can add missing places all around the different destination they visit. So tourist visiting the place can have more ideas or options on what to do in the city or where to visit in the city to spend quality time.
