Workshop Topics

• What is GIS?
• Data used in ArcGIS
• Performing basic operations in ArcGIS
• Looking at table data
• Changing Symbology
• Making queries
• Making a layout
• Campus Resources

3

• The amount of information you can
• get from a paper map is limited to what is shown

Agriculture Map of Georgia

A geographic information system (GIS) is a
computer-based tool for mapping AND analyzing
things that exist and events that happen on Earth.
5

• These abilities distinguish GIS from other
  information systems and make it valuable to a
  wide range of public and private enterprises for
  explaining events, predicting outcomes, and
  planning strategies.

6
With digital mapping technology, maps can be used
to help

• A water department find the valves to isolate a
  ruptured water main
• An engineering department monitor the conditions
  of roads and bridges and produces planning maps
  for natural disasters
• A business evaluate locations for new retail
  outlets by considerations concentrations of
  nearby customers

• A transit department produce maps of bicycle
  paths for commuters
• A hydrologist monitor water quality to protect
  public health
• A biologist study the impact of construction
  plans on a watershed.

Major Companies Using GIS

• Federal Agencies
• Chase Manhattan
• Sears Roebuck Co.
• Dominos Pizza
• Realtor.com
• MBNA
• Metropolitan Life
• Police and Fire Depts

• Ace Hardware
• Golds Gym
• US Postal Service
• Minolta Corp.
• Conectiv
• UPS
• AAA
• State/Local Govt

Simply said

• Geographic maps
• Information data
• System digital
• A GIS links information to geographic location
  (connects the what to the where), allowing you to
  seek patterns and relationships that may not
  otherwise be apparent.

9
What GIS Can Do for You

• Explore see and interpret spatial relationships
• Analyze create new information and find hidden
  patterns
• Present results ready your maps for output

10
GIS uses more than just geographic data

• Start with geographic data, such as a county
• Attribute data that has a relationship to this
  county can include
• mean monthly humidity
• average rainfall
• average acres of crops
• population and demographics
• zip codes, census tracts, etc.

By mapping more than one county that has these
attributes, a new map can be produced to show the
comparison between the attribute data.
11

• So, each layer contains 2 kinds of information
• Spatial information location and shape of the
  geographic features
• Attribute information other characteristics of
  the features

• The current trend in GIS is on web-based
  mapping. This capability can allow users to view
  an already created map or create maps, based on
  their own specifications, on their personal
  computers. Web-based mapping is expected to
  widely expand the use of GIS in the workplace, in
  schools, and in homes.
• Sometimes a nice geographic map is enough.
• For example

D a t a

• Possibly the most important
• component of a GIS is the data.
• A GIS will integrate spatial data with other data
  resources
• A GIS provides the path to the data, which are
  shown in the software as layers

20
A bit about layers

• Layers can be features or surfaces

Polygons
Lines
Points
Raster
21
Where do you get this data?

• GIS
• CD-ROMs/DVD-ROMs
• Morris Library, RDMS, or commercially
• Internet
• Colleagues
• YOU provide it!

22
