=== Google Earth ===
[http://earth.google.com/ Google Earth] gives you an annotated eagle's eye view of our planet. This is a free proprietary package (you must accept the license to use this package).

:Doubleclick on the resulting .deb file.

::::-- or --

To install the latest Linux binary, download and save the GoogleEarthLinux.bin package from [http://earth.google.com/intl/en/download-earth.html Google Earth downloads].
<!---> wget <nowiki>http://dl.google.com/GoogleEarthLinux.bin</nowiki><--->
Then install:
 chmod +x GoogleEarthLinux.bin
 ./GoogleEarthLinux.bin

Run:

:Applications -> Internet -> Google Earth 3D planet viewer

You should turn off the Google Earth -> View -> Atmosphere setting, or you might see clouds everywhere and the ground won't show up.

==== Troubleshooting ====
If Google Earth opens, shows the splash screen, and then crashes, you’re probably experiencing a common issue. Running ~/google-earth/googleearth in a terminal will show this error:
./googleearth-bin: relocation error: /usr/lib/i686/cmov/libssl.so.0.9.8: symbol BIO_test_flags, version OPENSSL_0.9.8 not defined in file libcrypto.so.0.9.8 with link time reference

To fix this, browse to the folder you installed Google Earth into. By default this will be google-earth in your home folder. Find the file libcrypto.so.0.9.8 and rename it to something else, like libcrypto.so.0.9.8.bak. Google Earth should now start correctly.

 cd ~/google-earth
 sudo mv libcrypto.so.0.9.8 libcrypto.so.0.9.8.bak
 sudo ln -s /usr/lib/libcrypto.so.0.9.8 ~/google-earth/libcrypto.so.0.9.8

:(Note: You can also specify /home/''user''/google-earth instead of ~/google-earth ).

For other issues, see the [https://help.ubuntu.com/community/GoogleEarth Ubuntu help pages on Google Earth].

==== Uninstall Google Earth ====
To uninstall run the ''uninstall'' shell script located in the /home/''user''/google-earth folder (or whichever folder you installed google-earth into).
