I got wind of this a couple of months ago and it appears to still be available. The Google Earth that we’ve been using has not been the professional version. I always suspected that there was more to the experience. Now anyone can download the pro version which comes with a suite of professional-grade features, like a map-making tool. Previously over $400/year, there is no cost to this version.
