How to access a raster catalog

Accessing a raster catalog

A raster catalog can be stored in an ArcSDE geodatabase, a file geodatabase, or a personal geodatabase. To access a raster catalog, follow these steps:

Open a raster workspace from the geodatabase. See Accessing raster workspaces for details.
Use the IRasterWorkspaceEx interface to access the raster catalog.

The following code example shows how to access a raster catalog in a geodatabase:

[C#]


        static IRasterCatalog OpenRasterCatalog(IRasterWorkspaceEx rasterWorkspaceEx, string
    catalogName)
{
    //Open a raster catalog in a geodatabase (PGDB, FGDB, or ArcSDE).
    return rasterWorkspaceEx.OpenRasterCatalog(catalogName);
}

[VB.NET]


        Public Function OpenGDBRasterDataset(ByVal rasterWorkspaceEx As IRasterWorkspaceEx, ByVal datasetName As String) As IRasterDataset
    'Open a raster dataset in a geodatabase (PGDB, FGDB, or ArcSDE).
    Return rasterWorkspaceEx.OpenRasterDataset(datasetName)
End Function
