We mentioned last week that Google Maps Engine is being shut down and as a result three Google Earth Pro only layers that depended on Google Maps Engine have been dropped. They were still visible over the weekend, but as of Monday 1st February 2016, they are no longer showing in Google Earth Pro. Google Maps Engine appears to have been shut down today, 2nd February 2016.
Another Google mapping related product is the mobile app My Tracks. According to its support page it will not be available after April 30, 2016. We at first thought that My Tracks might have been dependant on Google Maps Engine, but have not been able to find any evidence of this.
Google Maps Engine does have a lot of user created maps. One of the first things Google did after announcing its deprecation a year ago was to remove those maps from the Google Maps Gallery, which had a noticeable effect on the quantity of interesting maps available. However, new maps based on the newer My Maps are being created all the time so be sure to check out the gallery if you have not done so recently.
Another effect of the deprecation of Google Maps Engine is that Google stopped releasing imagery update maps via that platform. The last such map to be released was the May 2015 update. Since then, they have used the Voyager layers to provide imagery update maps, but much less frequently with only two so far being released.
