Objectives
- Students will explain the term "Global Positioning System" (GPS).
- Students will describe how GPS technology helps farmers examine fields
for crop yield, crop damage and how it assists in mapping soil conditions.
Activity Summary
Students will read the background
information about Geographic Information Systems and Global Positions
Systems.
Discuss the following question:
What ways do farmers use GPS?
If possible, bring a GPS receiving unit into the classroom, and discuss
other applications of this technology with students.
Students can view where they live from space by experimenting with different
Earth Observing Systems that
are available on various Web sites.
Extension Activity
Since this is rapidly evolving technology, students can search for additional
current resources on the WWW using the following search terms:
(global position* system*) or gps
(geographic* information* system*) or gis
(satellite* with (image* or survey* or data or map* or photograph*
))
((precision) NEAR (farming* or agriculture*))

About NASA'S EOS
The Earth Observing System (EOS) consists of a science component and a
data system supporting a coordinated series of polar-orbiting and low
inclination satellites for long-term global observations of the land surface,
biosphere, solid Earth, atmosphere, and oceans.
