A class group forms a logical container for a class. You can assign each class in the VertiGIS Data Dictionary to a class group.

A class group is uniquely identified using a numeric key. Class groups have a display name, a sort order and can refer to sub-class groups. However, ring closures are not permitted.

You can localize the display name and adapted it to different languages.

Class groups allow you to structure projects and assign hierarchies to classes.
