Google has also added more historical imagery, which allows users to see earlier photography of the same location on a timeline (from 1945 to the present). Furthermore, it's now easier to spot said imagery: when you fly to an area where it is available, the date of the oldest imagery will appear in the status bar as a clickable option at the bottom of the screen.
Last but not least, Google Earth now has 3D trees to make its environments more realistic. Google says dozens of species of trees are represented in a number of 3D-modeled parks and public places. The search giant has planted more than 80 million virtual trees in places such as Athens, Berlin, Chicago, New York City, San Francisco, and Tokyo, with more to come.
