Google Earth is a free-of-charge, downloadable virtual globe program. It maps the entire earth by pasting images obtained from satellite imagery, aerial photography and GIS over a 3D globe.
This version (4.0 beta) is native Linux version, it USES QT 3, and not wine. Few months back I had attempted to use wine based version. It was a bad experience.
Google recommend following configuration:
=> Kernel 2.6 or later
=> glibc 2.3.5 w/ NPTL or later
=> x.org R6.7 or later
=> System Memory (RAM): 512MB
=> Hard Disk: 2GB free space
=> Network Speed: 768 Kbits/sec
=> Graphics Card: 3D-capable with 32MB of VRAM
=> Screen: 1280x1024, 32 bit color
Google Earth puts a planet's worth of imagery and other geographic information right on your desktop. View exotic locales like Maui and Paris as well as points of interest such as local restaurants, hospitals, schools, and more. It is a worth to try out software.
