Easy Mapping Techniques Using ArcGISLoading A Map

• With ArcMap Open, click the Add Data toolbar
• Search for the shapefiles (.shp) in the folders
  you created earlier and click Add

19
Easy Mapping Techniques Using ArcGISQuerying

• With the layer, dtl_cnty checked, go to
  Selection gtSelect By Attributes
• Query the attributes (see illustration)

Easy Mapping Techniques Using ArcGISSelecting
Creating Layers Out of Selection

• Selected features (counties of Washington State)
  are highlighted
• Create a new layer out of the selected features
  (see illustration)

21
Easy Mapping Techniques Using ArcGISCreating
Shapefiles

• Create a new shapefile out of the layer (see
  illustration) make sure to create your desired
  .shp filename in your folder (for easy access)
• Add the new shapefile using Add Data toolbar

Easy Mapping Techniques Using ArcGISCreating A
Choropleth Map

• Choropleth maps are thematic maps in which areal
  units are shaded in proportion to measurement of
  variable (e.g. population density)
• Right Click Layer of interest and Select
  Properties

Easy Mapping Techniques Using ArcGISCreating A
Choropleth Map

• With Layer Properties opened, go to Symbology and
  then select Quantities gt Field (POP05_SQMI) gt OK
• A choropleth map showing population density
  (2005) per county within Washington State is shown

Easy Mapping Techniques Using ArcGISAdding
Fields and Calculating new variables

• Examine Table Attributes of your created
  shapefile
• Let us say we are interested to see the spatial
  distribution of proportion of blacks per county
  in Washington State
• We can create a new attribute(variable) (say,
  variable name, pblack) for this by using the
  formula
• pblackblack/pop2000

CSSCR Back-to-School Seminar, Fall

25
Easy Mapping Techniques Using ArcGISAdding
Fields and Calculating new variables

• We first add a new field
• Open attribute table
• Right Click and Select Add Field

CSSCR Back-to-School Seminar, Fall

26
Easy Mapping Techniques Using ArcGISAdding
Fields and Calculating new variables

• With the Add Field window open, fill-out variable
  specifics (name pblack, type double)
• Right click the new variable, pblack, and click
  Field Calculator
• With the Field Calculator window open, calculate
  the values (see illustration)

27
EXERCISE ALERT!!!1. Make a choropleth map using
the new variable, pblack.2. Try exploring other
map types, e.g. population dot maps
28
Easy Mapping Techniques Using ArcGISMap Layout

• With our desired map made, we can proceed to
  create our map layout
• Go to View gt Layout View
• In the Layout View, we can add the classic
  elements of maps, e.g. Title, Legend, Scale,
  Direction
• We can save the map and convert it into image
  file by going to File gt Export Map gt

  resources relating to ArcGIS mapping
• Advantages and Disadvantages of using ArcGIS
• Stay tuned for future CSSCR Back-to-School
  Quarterly classes that will feature GIS Mapping
• Geoprocessing
• Spatial Statistics
• Subject/Theme-related mapping techniques
  (demographic, housing, environmental, etc.)
