Google Earth Pro is the professional version of Google Earth. It's downloaded upon registration on its website and adds some extra features to the free version. Do these additional functions make a difference? Let's dig a bit deeper.
Making use of a vast satellite imagery database – actually the same as the free version, Google Earth Pro displays locations from all over the world, enabling you to zoom in from the image of the whole planet to the streets of any capital city. As a Pro version user, you're supposed to enjoy a faster performance, but we couldn't really notice any difference.
Another interesting feature included in Google Earth Pro is the ability to record videos with your movements around the world, which you can use to illustrate trips or even give directions. You can choose different resolutions, but record only in WMV format.
Technical support assistance, Premium print and a GID data importer are other additional capabilities of this Pro version.
However, taking into account that both versions share the same image database, which in the end is Google Earth's biggest value, you may as well use the free version.
