Earth Viewer
Welcome to Earth viewer. You can view either a
map of the
Earth showing the day and night regions at this moment, or view the
Earth from the
Sun,
the Moon,
the night side of the Earth, above any
location on the planet specified by latitude,
longitude and altitude, or from a
satellite in Earth orbit.
Images can be generated based on a topographical
map of the Earth, up-to-date weather satellite imagery, or
a composite image of cloud cover superimposed on a map of the Earth.
Expert mode allows you additional control over
the generation of the image. You can compose a custom
request with frequently-used parameters and save it as a
hotlist or bookmark item in your browser.
Please consult the
Earth viewer details for additional
information.
To use the Earth viewer, you need a graphical Web browser with forms
support and the ability to display GIF images.
Windows users can create images like this in real time, on their own
machines, as well as view the sky, stars at the horizon, the solar
system, orbits of asteroids and comets, and more with
Home Planet, my public domain
Earth/Space/Sky simulator available for your
FTPing pleasure. Other public domain
astronomy and space software available from the same site includes:
- On the Web:
- Solar System Live: interactive orrery.
- Terranova: a new terraformed planet every day.
- For Windows:
- Home Planet,
Sky screen saver,
Moontool,
Craters screen saver, and
an Excel catalogue of the Palomar
Observatory Sky Survey.
- For Unix (X/OpenWindows):
- Moontool, and
Xsunclock.
All of these packages and more can be located from my
home page.
The Earth viewer would have been enormously more difficult to implement
without the help of the freely distributed software mentioned in
the credits.
