Field Trip is a somewhat experimental project out of Google's Niantic Labs, an internal start-up that is also responsible for the game Ingress. Field Trip is a location-aware experience just like Ingress, but its purpose is to alert you to notable stuff in your general vicinity. Showing you mildly interesting landmarks is one thing, but Field Trip can now get you free admission to 13 museums in addition to telling you where they are.
Indoor maps are becoming the hot new thing in the world of not getting lost. Google may be using fancy 3D planes to map everything the sky can see, but sometimes it's just as easy to get lost in a train station as it is in a city. Google's recent indoor maps have made navigating easier, and now UK locations are being added to the supported list.
The maps have been seamlessly integrated into the Google Maps app.
