Google Earth Beta 5 Lets Users Explore Ocean Floor
Google's latest update to Google Earth includes several new features to view, including the three-dimensional renderings of the ocean floor, historical satellite imagery and maps of Mars. This is the first update to Google Earth since the 4.3 version.Google's fifth update to its popular Google Earth software offers something for virtual tourists, planetary exploration enthusiasts and amateur oceanographers. Fans of seeing your favorite places from overhead-not to mention your favorite artwork-those high-resolution images are still there for your procrastinating pleasure. Available for free download from Google's Web site, Google Earth 5.0 can plunge viewers as far down as the Mariana Trench, the deepest location in the seven seas; it can also let you roll back the years, showing what areas such as Silicon Valley looked like five or even 50 years ago (a more disturbing aspect of this allows you to watch glaciers shrink); and it provides a three-dimensional view of the Martian surface.
Previous versions of Google Earth included an ocean that was virtually a monochromic blue, with only slight shadings to convey depth.
