Part III
Retrieving, Counting, and Characterizing Geography
In this part . . .
The data you put into your GIS isn’t much use to you if you can’t search out specific data, compile that data, and then analyze and interpret to make sense of it. This part shows you how to retrieve just the right data and then turn that data into the information that meets your needs. In this part, you find out how you can describe the geographic data you find both numerically and by type. You also see how you can order geographic features by their sizes and shapes, as well as by their locations — both in absolute and in relative terms. Searching out and characterizing geographic data are powerful skills that serve you well when you work with GIS.
