Xeric Design has released EarthDesk 6.0, an upgrade to its real-time dynamic desktop map. The upgrade adds new mapping features.

EarthDesk replaces your static desktop with an image of the Earth showing current sun, moon and city illumination, as well as global cloud coverage. The software operates silently in the background, keeping your desktop updated while you work.

Among the improvements in version 6.0 are map grid lines, plotting of cities, tracking the International Space Station and new shading options. Also, EarthDesk can now label and plot user-selected cities on any map display

EarthDesk 6.0 works with Mac OS X 10.6 or later. Single-user copies may be purchased for US$24.95. Upgrades are available for $12.95 for licensed users of version 5 and $17.95 for licensed users of versions 1, 2, 3, and 4.

High-resolution cloud access is available starting at $9.95 for a single user. A bundle including EarthDesk and high-res cloud access costs $32.95. For more info go to http://www.xericdesign.com/earthdesk.php .
