Google has announced that they are finally shutting down the Google Earth API /plugin on Wednesday, January 11, 2017. They first announced its deprecation in December 2014, giving it a year. In December 2015, they gave it a temporary reprieve, which is finally running out.
We will miss it, as it was a good way to access information about historical imagery and we used to create imagery update maps using it. However, since June, Google has not updated the ‘historical imagery’ layer (other than the recent addition of the global Landsat/Sentinel mosaics)
Google Earth 4
At the same time, Google is ending support for Google Earth 4. Anyone running Google Earth 4 will no longer be able to access imagery from January 11, 2017. The current latest version is 18.104.22.16806
If you absolutely need an older version, you can download older versions going back to Google Earth 5.0 here.
Here’s hoping Google can come up with a new Google Earth API that allows us to control Google Earth and query its data.
One of the uses we had for the Google Earth API was studying [historical imagery density](One of http://www.gearthblog.com/tag/historical-imagery-density).
