Using World Wind, you can continue
to zoom past Blue Marble and reveal the extremely detailed seamless
mosaic of LandSat 7
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
