Importing Spatial Data
Many spatial applications combine custom-defined spatial features, such as the location of a set of customers, with spatial data representing widely accepted, generic features on the earth, such as the boundaries of countries and states, the locations of major world cities, and the paths of main roads and railways. Rather than having to create this information yourself, there are a number of alternative sources from which you can obtain commonly used spatial data on which to base your spatial applications.
