" This site provides information on obtaining
free or low cost Landsat, GOES, and Space Shuttle
images. Also included are links to free satellite
image processing software. Tip sheets will show you
how to create 3D perspective views of Landsat images
and how to colorize GOES weather satellite imagery.
"In the past, satellite imaging was the exclusive
domain of professionals working for government or
university organizations. Thanks to advances in desktop
computing and the wide spread availability of the
Internet, satellite imaging can now be enjoyed by
an enthusiast in the comfort of one's home.
"Images from earth resource satellites, weather
satellites, and the Space Shuttle in a variety of
resolutions are all easy to obtain via the Internet.
This site will show you where to obtain such imagery,
and teach you a few techniques for image processing
satellite images." - Mike Brown's Satellite Imagery
Two MultiFAX demodulators are available for an expansion
slot or externally via the parallel port. Extensive

This NASA funded project provides students with control
of a camera on the shuttle in orbit. The goal is to
integrate satellite imaging into the teaching of Earth
Science. Headed by Sally Ride.
Space Commerce Initiative
A collaboration of NASA Stennis Center and several companies
and universities to develop remote sensing technology
and applications. Several useful pages including links
to RS companies.
"...dedicated to making remote sensing algorithms,
code, and technology available to all interested parties.
Resources are provided to facilitate communication
and development of open source tools. It is hoped
that this effort will attract participation from companies,
students, professors, and agencies that are involved
in remote sensing efforts."

of the oceans and of space. SeaSky
A company that provides software to do processing of remote
sensing images to develop their full information potential.
The first private commercial remote sensing satellite
company. It provides primarily images from the French

Earth Observing System (EOS) Education Project
- "develops interdisciplinary programs, and deploys
advanced technologies to the global K-16 education
community. We investigate how geo-technologies help
enhance our exploration and understanding of the diverse

Earth - Large educational site dedicated to the
theme of studying the earth as a total system: weather,
oceans, solar input, etc. Space offers the best vantage
point to study the earth and many different kinds
of satellite observers will be launch in the next
few years as part of NASA's Earth Science Enterprise.
imaging has become an increasingly important remote
sensing tool. While the resolution is not as fine as
for visible light images, radar can penetrate clouds
and works at night as well as it does in the sunlight.
Satellite Radar imaging has become an increasingly important
remote sensing tool. While the resolution is not as
fine as for visible light images, radar can penetrate
clouds and works at night as well as it does in the
sunlight. See the Using
RADAR Data - Science and Applications page for information
on this exciting RS technique.
The RADARSAT-1 satellite is owned and operated by the
Canadian Space Agency and it license the distribution
of its images to a private commercial company. However,
NASA launched the satellite and works closely with the
CSA in the analysis of the imagary.
GIS is a relatively new field that combines
the many types of remote sensing data with the many
types of conventional ground based information into
one big multi-dimensional database. One can then create
plots and maps illustrating interesting and often unexpected
correlations among the various parameters.
For example, one could use such a database
to relate housing density (obtained from a satellite
image) versus median salary levels (obtained from census
data.) Or versus toxic release sites (from environmental
Such analysis is becoming a very popular
tool for many applications ranging from demographics
to city planning to placement of cellular phone towers
to environmental monitoring.

does processing of imagery from a variety
of satellite sources. They offer "value-added"
products such as crop forecasting, geologic analysis,
and other remote sensing services.
While these are not hobbies,
they provide interesting illustrations of the capabilities
of satellite remote sensing.
Animal researchers and environmentalists
have always needed to track creatures in the wild to investigate
their behaviour and range of activities. While hiking
boots and binoculars are still required tools, so now
are satellites when it comes to tracking animals over
long remote distances and over long periods.
Lost cities, roads, and other ancient constructions
that were invisible from the ground have been found
to "stand out" when seen from the perspective
of space. Furthermore, sensors such as radar can penetrate
jungle foilage or sand and also scan large areas very
The applications of remote sensing in law enforcement,
forensic, and other legal areas are growing. These can
range from spotting ships at sea illegally fishing or
dumping pollutants to settling real estate disputes.
This company uses d satellite terrain data to create a
computer simulations for courtroom use. For example, they
provided simulations to support the pilot in the case
of the US Marine plane that accidentally cut the cables
to a gondola in Italy, resulting in the deaths of 20 people.
Farmers can now combine remote sensing data,
e.g. images that indicate the water content of the soil
and plants, and GPS positioning information (also from
satellites, of course) to tailor their plowing, fertilizing,
planting, irrigation, pest control, etc. down to the square
The Precision Agriculture Center at the University of
Minnesota describes the techniques of precision farming.
Precision Farming combines GPS and remote sensing data
to tailor planting, irrigation, fertilization, etc. to
particular areas within individual fields.
It might seem seem strange
to go to space to predict earthquakes but, in fact, satelllite
sensing may provide vital clues to detecting precursors
to seismic activity. Radar and GPS systems can since movements
of the earth to centimeter accuracy and thus signal slight
shifts of tectonic plates that may occur before quakes.
There are indications that low frequency electromagnetic
radiation may be emitted from ground structures under
stresses that precede a quake. Satellites may have already
detected such radiation and new
projects are underway to test the theories.
