3GIS OVERVIEW
An acronym for geographic information system An
integrated collection of computer software and
data used to view and manage information about
geographic places, analyze spatial relationships,
and model spatial processes. A GIS provides a
framework for gathering and organizing spatial
data and related information so that it can be
displayed and analyzed.

5What is Remote Sensing?
- The collection and interpretation of information
about an object without touching the object.
"Remote sensing is the science (and to some
extent, art) of acquiring information about the
Earth's surface without actually being in contact
with it. This is done by sensing and recording
reflected or emitted energy and processing,
analyzing, and applying that information."

14Why is Accurate Land Cover Important?
- Land cover reflects
- The state of the land
- The management of the land
- Change maps indicate trends
- Impacts the life of people living on the land
- Water quality surface and ground
- Wildlife and recreation
- Atmospheric pollution
- Climate microclimate and macroclimate
- Erosion wind and water
