Download google places database from a city area

Hello all, does anybody have an idea how could i pool out from google maps all the ,google places, from a city area (bars, churches, pharmacies, buildings, rivers etc…) in to one ,spread, according to some gps positions?

I want to make an experimental piece where according to our gps positions the city’s places have different sounds sequencing some sounds.

I don’t know where to start, checked the google maps api but it’s huge.
If you have any advice I would be very thankfull :-)
