Google Premium/Enterprise vs. Google Earth Professional License

A "Google Premium/Enterprise" is not the same as a Google Earth Pro
license.

The "Google Premium/Enterprise" allows usage of the Google
Products, API's and Mapping Layers on websites and internal use.

A Google Earth Professional license only allows you to use Google Earth
Professional Application in a commercial environment.
