GIS Environmental
Science Institute
University
of Pacific Stockton, California July 1998
 |
This
two week long workshop provided science instructors from throughout the
country a chance to experience with the Geographic Information System(ArcView).
Throughout the workshop participants shared, learned, and developed a better
understanding of the the capabilities of GIS.
WHAT IS A GEOGRAPHIC
INFORMATION SYSTEM?
GIS
is a highly developed graphic software
that allows the user to create an extensive database.
The development of a database allows the user to begin asking spatial questions
about relationships that exist between different layers of data.
Data is portrayed in three different forms: POINT, LINE, and POLYGON. |

This world tectonic map
represents the three data types overlain on the world map. Spatial
relationships between data becomes evident in this world tectonic map.
The relationship between tectonic boundaries, earthquakes, volcanoes and
faults are evident in this image.

Thanks to everyone who participated
in this two week institute and a special thanks to Dick, Gene, Curtis,
and Lydia for their patience, expertise and hospitality.
(Imagine this image bobbing up and down as Gene explains this formation.)
Dick thinking of what other wonderful things he can do for us.
THANK YOU!!
"GLOOP" - a geologic term used in describing movement associated
with mass wasting.
