 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:
  pblack=black/pop2000

EXERCISE ALERT!!!
1. Make a choropleth map using the
new variable, pblack.
2. Try exploring other map types, e.g.
population dot maps
                                                                    A. A. Ortega
  Easy Mapping Techniques Using ArcGIS|Map Layout


  With our desired map made, we can proceed to create our map
   layout
  Go to View > 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 > Export Map >

  If lost….always check on the HELP Menu Bar
  There is a plethora of tutorials, data and other 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
