ArcMap Basics

  • Overview

    • Getting data into ArcMap

    • Displaying layers

    • Layer display properties

18 of 49


Displaying layers l.jpg
Displaying layers

  • Displaying layers

    • Why alter layer display?

    • What do you want to communicate?

raw population

population density

Displaying layers thematic mapping l.jpg
Displaying layers: thematic mapping

  • Single symbol

    • A single symbol for each feature

    • Displays location/boundaries

21 of 49


Displaying layers thematic mapping22 l.jpg
Displaying layers: thematic mapping

  • Unique value

    • Different symbol for each feature

    • Shows variation in value

22 of 49


Displaying layers thematic mapping23 l.jpg

  • Graduated color = “choropleth”

    • Different symbol for each class

    • Displays groups

23 of 49
