Object collection   

An object collection is a set of ILWIS objects.

An object collection only stores the names and locations of the object definition files of the maps, tables, etc. that are included in the object collection. The object definition files of these maps, tables, etc. contain further references to the names and locations of the data files on disk.

Object collections:

• can be created to organize your data as 'projects';
• are the result of importing Aster images through ILWIS Map Import.

Furthermore, a special case of object collections are database collections. Database collections are the result of accessing an external database, and only contain the Use As tables _u of the external database.
