NASAWorld Wind 1.4.0 is better than google earth
World Wind is developed at NASA Ames Research Center by Chris Maxwell,
Randy Kim, Tom Gaskins, Frank Kuehnel and project manager Patrick
Hogan.
3D Engine
World Wind allows any user to 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.
Particular focus was put into the ease of usability so people of all
ages can enjoy World Wind. 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.
Land Sat 7
Using World Wind, you can continue to zoom past Blue Marble and reveal
the extremely detailed seamless mosaic of LandSat 7 data.
LandSat 7 is a collection of images from 1999-2003 at an impressive 15
m per pixel resolution. It includes other color bands such as the
infrared spectrum. Users will be able browse these different sets as
they become available. Any changes and updates are automatically
inherited by World Wind.
LandSat 7's resolution makes it possible to see your own city,
neighborhood, or landmarks in your vicinity. Seeing the whole globe
like this puts the world in context with scientifically accurate data.
The complete LandSat 7 data set is too large to fit on a single machine
so World Wind only downloads what you see and stores a compressed copy
on your computer for later viewing.
