This data set provides six levels of generalization for displaying the data at different scales. Everything about the levels is the same but the level of generalization and its name. The least generalized level is called <data set name>. The next more generalized level is called <data set name>_1, and so on. For best performance, use the most appropriate generalized level when displaying or printing.
