Starting today, anyone interested can go grab a Pro key for Google Earth, completely free of charge. After announcing that the Earth API for developers will completely shut down at the end of this year, Google appears to be moving more towards the mobile side of things, but still have yet to give official word on their plans for the future of Earth and desktops.
With Earth Pro, builders and designers can place their own creations onto Earth, allowing for proper sizing and proportion designs. Basically, if you need it for your geographical-based work, it’s a good thing to have. However, if all you like to do is look at satellite images and zoom around from place to place, it may not be necessary to own.
