Via this thread How to view in Google Earth?, here’s how to do this:
To view your maps in Google Earth, you’ll need to do the following:
Export your data : http://support.dronedeploy.com/v1.0/docs/exporting-your-data108
(you can read more about data exports here : http://support.dronedeploy.com/docs/data-output-formats-v246 )
Import into Google Earth:https://support.google.com/mymaps/answer/3024836?hl=en
Please let me know if this works.
