How do I create a raster catalog in ArcGIS?
Once a raster catalog is created, raster datasets can be loaded into it by right-clicking the raster catalog and selecting Load Data. Raster datasets can also be loaded into a raster catalog using the Workspace To Raster Catalog tool. Raster catalogs can be managed or unmanaged by the geodatabase.
Where are the raster datasets stored in ArcGIS?
Raster catalogs can be managed or unmanaged by the geodatabase. When the raster catalog is managed by the geodatabase, then the raster datasets inside the raster catalog will be physically stored within the geodatabase. When a row or raster is deleted from the catalog, it is deleted from the geodatabase.
Can a geodatabase be loaded into a raster catalog?
Geodatabase raster datasets can only be loaded into raster catalogs that are managed. Raster Catalogs stored in an ArcSDE geodatabase are always managed. It is recommended that you use the Workspace To Raster Catalog tool to load data in the raster catalog so that the spatial grid size will be automatically calculated.
How do you add rasters to master mosaic?
Right-click the master mosaic dataset in the Catalog window and click Add Rasters . Click the Raster Type drop-down arrow and click the appropriate service type, such as Image Services or Map Service . Click the Input browse button and select the layer file you created.
What happens when the raster catalog is unmanaged?
When the raster catalog is unmanaged, the raster catalog only contains links or pointers connecting a raster catalog row to a raster dataset stored outside the geodatabase. These raster datasets are stored outside the geodatabase.
