Adze can export documents or individual tracks as KML files which can be opened in Google Earth™ or shared with friends online.
To export tracks as KML files, select the tracks or track segments you wish to export and then choose the menu item File → Export Selection As... → KML. An Export Selection dialog will appear and allow you to choose a location to save the KML file. This file can then be opened in Google Earth™ or sent via email et cetera.
You can display tracks directly in Google Earth™ without exporting to a KML file and opening it manually. Start by selecting the tracks or track segments you wish to display, then choose the menu item Selection → Show Selection in Google Earth. Google Earth will open and zoom to display the exported data.
For this feature to work, Google Earth must be installed in the Applications directory and named "Google Earth".
