What is GIS?
• A geographic information system (GIS) lets us
visualize, question, analyze, and interpret data
to understand relationships, patterns, and
trends.
• GIS benefits organizations of all sizes and in
almost every industry.
• Let’s break it down.

G - Geographic
• Geographic location - It is a spatial location
that describes where something is physically
located, using the geographic coordinate
system. GCS consists of a latitude (y)
coordinate and longitude (x) coordinate.
• All objects have an x and y location on earth.
You have a geographic location though your
position is constantly changing as you move
around.

Example
35.125921 = Latitude
-106.434002 = Longitude
The geographic
location of the
tree is
Latitude is the Y axis, longitude is the X axis

I - Information
• Information about the object, the tree.
![Page 6: The Fundamentals of GIS and Real World Applications...The Fundamentals of GIS and Real World Applications Presenter: Katrina Patton “The application of GIS is limited only by the](https://reader030.vdocuments.us/reader030/viewer/2022041111/5f142535a074417a0957d42d/html5/thumbnails/6.jpg)
Example
• Species – Ponderosa Pine
• Description – An evergreen, open-branched
tree native to western North America, adapted
to well drained soils in Arizona and New Mexico
• Cones – Reddish to yellow-brown elliptic cones
• Seeds – Winged brown-purple
• Height – 75’
• Condition of tree – poor, fair, good, excellent
• And any other information you might want to
collect about the tree

S – System(s)
• All the information about the tree is contained
in a database which is attached to the
geographic location.
• Put geographic and information together and
they encompass a system.
• They work together to create the whole.

GIS Technical Definition
• 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.
• GIS in its simplest form is "computerized
mapping".

A Look At Some Applications
• National Park Service
The National Park Service GIS applications include mapping natural and cultural resources such as endangered species, archeological sites, historic sites, inventorying facilities and assets for management and emergency response, exotic plant management, and tracking wildlife.
• Yellowstone National Park Thermal Inventory
Map each feature using GPSConduct water testing such as PH and electrical conductivity Obtain the temperature of the featurePhotograph and describe the feature

Do You Use GIS?
• Most likely the answer is yes. GIS is
everywhere.
• If you have every used Google Maps/Bing for
directions or to look up dining or shopping,
you have used a GIS-based application.
