Mosaic datasets in a geodatabase in Informix

Mosaic datasets contain a raster catalog and a set of properties and rules that define an on-the-fly mosaic view of the raster catalog. See What is a mosaic dataset? for more information.

Mosaic datasets in ArcGIS for Desktop

In the Catalog tree, mosaic datasets have the following icon:

The name of the mosaic dataset in a geodatabase in Informix contains the database name followed by a colon(:), the name of the dataset owner, and the name of the mosaic dataset itself.

Mosaic datasets in an IBM Informix database

Information about mosaic datasets is stored in the gdb_items and gdb_itemtypes system tables. There can be 12 additional tables stored in the schema of the user who creates the mosaic dataset. Four of them—the ART, BND, CAT, and LOG tables—are created when you use the mosaic dataset that's created; the other tables are generated the first time you perform an operation that requires the table's existence. Referenced mosaic datasets only have two tables: the BND and LOG tables.

The name portion of the table names is the name of the mosaic dataset. Be sure the name you give the mosaic dataset is 22 characters or fewer.
