THE DATABASE The Attribute Component
NOT EASY TO INTERPRET
HOWEVER

THE MAP THE SPATIAL COMPONENT
VISUALIZATION IS THE KEY TO GIS
A Map is Worth a Thousand Words

GIS Data Layers

• GIS data is represented in layers
• Like features are stored in the same layer
• Layers have both a spatial component and an
  attribute component

12
THE POWER OF GIS COMES FROM COMBINING DATA FROM
MANY SOURCES
13
AND FROM CREATING YOUR OWN DATA!

• Digitized and Scanned Maps
• purchased, donated, free (Internet)
• created by user
• Databases, Tables, Charts Spreadsheets
• GPS Global Positioning System
• Field Sampling
• Remote Sensing Aerial Photography

COMBINING THESE LAYERS
Capitals
Rivers
Roads
States
Lakes

ALLOWS US TO TURN DATA
INTO INFORMATION!
