Google Earth is a software that displays through a three-dimensional representation of the earth the various places of our planet through the maps also available on Google Maps. Google Earth is present in AUR as Unsupported PKGBUILD. It obviously requires that the X server hardware acceleration is enabled.
To install it you can follow two ways:
Download the tarballs (Archive) from AUR
Extract it in a folder in your home, then enter through the terminal, compile and install it.
