This is a ruby on Rails demo app using Address autocomplete with google places API. РЕКЛАМНЫЙ БУКЛЕТ

In this app you can search for a geocode address or establishments, move the marker and get the the GPS coordinates, and also get the gps coordinates out the search results.
it’s also possible to restrain the autocomplete results by limiting it to bounds:
