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.

World Wind was designed to run on recent PC hardware with 3D
acceleration. Please refer to the download section for more information
on system requirements.

World Wind has a full copy of the Blue Marble, a spectacular
true-color image of the entire Earth as seen on NASA's Earth
Observatory: the Blue Marble.

Put together from data of a variety of satellites such as MODIS
and Terra, the Blue Marble can be seen in all its glory at 1 km per
pixel resolution.

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.

SRTM

Combining LandSat 7 imagery with Shuttle Radar Topography Mission
(SRTM) Data, World Wind can display a dramatic view of the Earth at eye
level. Users will literally be able to fly across the world in any
direction.

In addition, World Wind can exaggerate these views so a user can easily pick out the details.

Goddard Space Flight Center (GSFC) has produced a set of visually
intense animations that demonstrate a variety of subjects such as
hurricane dynamics and seasonal changes across the globe.

World Wind can take these animations and play them directly on the
world. Anyone can immediately grasp where the event is taking place as
World Wind rotates automatically into view.

MODIS

Moderate Resolution Imaging Spectroradiometer or MODIS produces a
set of time relevant data that's updated every day. MODIS catalogs
fires, floods, dust, smoke, storms and even volcanic activity.

World Wind produces an easily customized view of this information
and marks them directly on the globe. When one of these color coded
markers are clicked, it downloads the full image and displays them.

MODIS images can download publication quality material at a
resolution of 250 m per pixel. Anew fresh set of images can be
downloaded every day.

World Wind is capable of browsing through and displaying GLOBE
data based on any time the user wants. For example, a user can download
today's (or any previous day's) temperature across the world.

You can view rainfall, barometric pressure, cloud cover, or even
the student GLOBE samples themselves. Each sample comes with a
temperature scale

Country borders across EuropeCountry & (USA) State Borders

World Wind has a complete set of borders that traces every country
and state. As you zoom into the world, the boundaries become more
precise

You can observe where mountain ridges and rivers have formed the political boundaries of today.

City areas around SydneyPlace names

World Wind has a full catalog of countries, capitals, counties,
cities, towns, and even historical references. The names update
dynamically, by increasing in number as the user zooms in. This
prevents too many names from cluttering up the screen.

It's likely that you'll find your own town no matter how big or small it is in World Wind
