[OSGeo-Edu] Fwd: [Gisideas] Free satellite images and tools from NASA and USGS

FYI (some of you will know), distributed with permission from a
different list. I see quite some potential to create educational
material...

Subject: [Gisideas] Free satellite images and tools from NASA and USGS

Perhaps you would be interested in a free tool and satellite data
provided by NASA and the US Geological Survey.  Its called TerraLook,
and provides time series of georeferenced jpeg images plus image
processing/GIS software.  It is intended to provide easy access to
satellite images for users with little or no prior experience, though
it also proves useful for experienced users who want a quick image,
such as for a presentation.

http://terralook.cr.usgs.gov/

The data includes global coverage layers of "best available" Landsat
images from about 1975, 1990, 2000 (and, soon, 2005).  ASTER data are
also available, and access is provided to the entire ASTER archive of
about 2 million images going back to 2000.  While full ASTER datasets
cost about USD100 per scene, these jpeg images are completely free.


The open source tool supports basic image processing and GIS
functions; a major update will be available around the end of the
year.  In fact, participation in tool development is welcome for those
who enjoy programming.  The tool can be downloaded from the above
website.


Also, collections of images on a country-by-country basis have been
made for many countries (including Vietnam and the other countries of
SE Asia) and can be downloaded (if these are of interest I can provide
master copies on media to Dr Pascual).  PowerPoint tutorials are also
available from the above site.


Finally, I should also mention that requests for new ASTER
acquisitions are also free, so that if you cannot find the image you
need in the ASTER archive, you can request an acquisition; only a
short justification and approval is required.  Once the data are
acquired you can then access a georeferenced jpeg of it for free using
TerraLook.  More information on ASTER is available at
http://asterweb.jpl.nasa.gov/


I hope this information is useful.


Best wishes,

Gary Geller
