Groups are feature classes representing the same phenomena at different levels of detail. For example, you can have very detailed breaklines for �edge of road� and more generalized breaklines that are �center of road�. Each is to be used at different scales. Assigning them the same group id will tell terrain they are thematically alike but must be enforced only in non-overlapping scale ranges.
