Google Earth And a little more

I use Google Earth more than Google Maps!
It can be used on Desktops, the Web or on Mobile devices [iOS and Android].

Today i discovered that there is also something like Google Earth Pro.

Google Earth Pro is a 3D interactive globe that can be used to aid planning, analysis and decision making. Businesses, governments and professional users from around the world use Google Earth Pro data visualization, site planning and information sharing.
