Reaping the World Wind
Who says the space program never produced anything interesting here on Earth (other than Tang)? NASA just released World Wind an open-source 3-D model of the earth that lets you "zoom from satellite altitude into any place on Earth, leveraging high resolution LandSat imagery and SRTM elevation data to experience Earth in visually rich 3D, just as if they were really there."
World Wind comes preloaded with a bunch of really cool geographic data sets, including NASA's amazing "Blue Marble" true-color image of the entire earth, 15m Landsat images, 3D data from the Shuttle Radar Topography Mission. GIS junkies can add their own data sets as well. Special bonus: incredible ease of use. "All one needs to control World Wind is a two button mouse. Additional guides and features can be accessed though a simplified menu. Navigation is automated with single clicks of a mouse as well as the ability to type in any location and automatically zoom into it.
I can't wait to see the kinds of interactive mapping projects enviro-GIS folks like CommEnSpace are going to be able to pull off with this tool.
