This data set provides six feature classes for displaying the data at different scales. Everything about the feature classes is the same but the level of generalization and its name. The base feature class is called data set name and isn't generalized. The least generalized feature class is called data set name_1, the next more generalized feature class is called data set name_2, and so on. For best performance, use the most appropriate feature class when displaying or printing.
