CHANGE Viewer
The Climate and Health ANalysis for Global Education Viewer (CHANGE
Viewer) is a free tool that can be used to access, analyze, and
visualize Earth science data. The CHANGE Viewer is easy to use and
offers opportunities for teachers and students to improve their
understanding of the Earth and issues relevant to human interactions in
the environment. The CHANGE Viewer also is easy to install and provides
capabilities for accessing global data sets to study the environment
and the effects of hazards on populations, property, and locations.
Workstation Requirements
The CHANGE Viewer application requires a modern graphics card with an
up-to-date driver, JRE 1.6.0, at least 2GB RAM and 30MB available hard
disk space.
Installation
Click on the link
CHANGE Viewer (
http://www.ciesin.columbia.edu/gcce/CHANGE_Viewer.jnlp
). Two dialog boxes will
appear. The first dialog will confirm that you have chosen to download
the CHANGE_Viewer.jnlp file. Select the "Open With" radio
button and choose "Java Web Start Launcher (default)" from
the list box and press the OK button. The next dialog to appear is the
Global Climate Change Education Program application's digital signature
dialog. Select the "Run" button. If the application fails to
start or the first dialog does not have a "Java Web Start Launcher
(default)" choice, then double check that your workstation meets
the minimum workstation requirements.
Common Installation Issues
The most common deployment issue is an out-of-date graphics driver. To
get an updated driver, visit your graphics card manufacturer's web
site. This will most likely be either
Nvidia,
ATI / AMD or
Intel.
The drivers are typically under a link named "Downloads" or
"Support". If your computer is a laptop, then updated drivers
are probably at the laptop manufacturer's web site rather than the
graphics card manufacturer.

Science Information Network (CIESIN), of Columbia University and the
