Create Mosaic Dataset (Data Management)

Summary

Creates an empty mosaic dataset in a geodatabase.

Usage

  • The mosaic dataset must be created in a geodatabase.

  • Once the mosaic dataset is created, you can use the Add Rasters To Mosaic Dataset tool to populate it with rasters.

  • Starting at ArcGIS AllSource 1.4, mosaic datasets created in Oracle, PostgreSQL, and SQL Server geodatabases will be created with the RASTERBLOB keyword. The RASTERBLOB keyword implements a transfer of the mosaic dataset catalog items to the DBMS.

  • Mosaic datasets created with the RASTERBLOB keyword cannot be opened with earlier versions of the software. To create mosaic datasets that are backward compatible with earlier versions, alter the configuration keyword for RASTER_STORAGE to one of the following compatible keywords:

    • BINARY for PostgreSQL and SQL Server
    • BLOB for Oracle

  • The name of the mosaic dataset must be in accordance with the limits of the geodatabase or underlying database; for example, the name cannot start with a number.
