Google Earth has received an update "two years in the making" that includes new guided nature tours from Sir David Attenborough.

The exploration app, which enables users to explore the planet thanks to satellite imagery captured by the technology giant has introduced several new features, including Voyager, a new series of guided tours of different parts of Earth.

It includes input from BBC Earth as well as exclusive content from Planet Earth II, the BBC series presented and narrated by Sir David.

The update has been made available for the Chrome web browser and Android versions of the app, and also includes improved and more detailed satellite imagery.

We want to open up different lenses for you to see the world and learn a bit about how it all fits together.

Google Earth's Gopal Shah said: "With the new Earth, we want to open up different lenses for you to see the world and learn a bit about how it all fits together; to open your mind with new stories while giving you a new perspective on the locations and experiences you cherish.

"It's everything you love about Google Earth, plus new ways for you to explore, learn and share. Zoom in and see what adventures await you in the new Google Earth."

A new 3D button has also been introduced to the app, which adds the ability to see any place on the map in 3D, a feature only previously available in specially designated locations.

The 'I'm feeling lucky' button, which first appeared on Google's search engine and carried out a random search for users has also been added to Earth, now automatically jumping to a random location and offering users information about it.

"You might discover the lush green Pemba Island off the Swahili coast, the historic La Scala opera house in Milan, Italy, or the Zao Hot Spring in Yamagata, Japan," Mr Shah said.

"We've curated 20,000 different places, so roll the dice and see where the world takes you."

Google said the new version of the app will be made available for Apple iOS users "in the near future".
