Google Earth - Dropbox Sync
Synchronise Google Earth places across multiple computers using Dropbox. The instructions are currently specific to OS X but can be extended to Windows and Linux.
~/Library/Application\ Support/Google\ Earth is moved to a
google-earth-sync directory under a Dropbox container directory. A symbolic link is then made to this directory.
The entire Google Earth data directory needs to be synchronised instead of just the
myplaces.xml file because of how Google Earth backs the file up. During the backup process after quitting Google Earth,
myplaces.kml is renamed to
myplaces.backup.kml and then copied to
myplaces.kml. If only the
myplaces.kml file were to be synchronised with a symbolic link then the synchronisation process would break after one cycle because the backup file would then be the symbolic link.
Migrate to Sync Directory
These instructions should only be performed on one machine, with the initial version of the
myplaces.xml file that should be synchronised.
Ensure that the Dropbox container directory exists:
mkdir -p ~/Dropbox/Apps/Google\ Earth/
Move Google Earth data directory to Dropbox sync directory:
mv ~/Library/Application\ Support/Google\ Earth ~/Dropbox/Apps/Google\ Earth/google-earth-sync
Reference Sync Directory
These instructions should be performed on all machines.
Back existing directory up:
mv ~/Library/Application\ Support/Google\ Earth ~/Library/Application\ Support/Google\ Earth\ backup
Create a symbolic link to Dropbox sync directory:
ln -s ~/Dropbox/Apps/Google\ Earth/google-earth-sync ~/Library/Application\ Support/Google\ Earth
Google Earth will now read and save to the Dropbox directory. If multiple copies of Google Earth are open at the same time then the saves will conflict and overwrite each other (no merge capability).
