Google Earth adds custom map-viewing to iPhone app

Google Earth is adding custom map-sharing to its iPhone app — so you can share anything from your favorite places in Barcelona to a preferred hiking trail with friends. (They’ve given a few examples, including Lonely Planet co-founder Tony Wheeler’s favorite destinations and Ferran Adria‘s recommendations for places to eat.)

While logged into Google Maps on a computer, you can save maps you’re interested in so they’ll appear when you log in to your iPhone app with the same credentials. You can also build your own maps in Google Earth manually or by hooking up a GPS-enabled device and turning your location data into a KML file.

Google has also made it easier to view local listings and has added 13 languages to the app.
