Mosaic dataset properties

There are three groups of properties for a mosaic dataset: General, Default, and Key metadata. The general properties are similar to those you find for all raster datasets, such as the data source, extent, cell sizes, and bit depth. The default properties are specific to the mosaic dataset and include all the nonraster dataset-specific information. These properties affect how the mosaicked image will be presented to the user (or client) and how they might interact with it. The key metadata properties are derived from the product definition, if one is defined for the mosaic dataset. It contains band and wavelength information used for rendering and some processing. The product definition can be modified on the General tab. For more information on the general or key metadata properties, see Raster dataset properties.

Any properties set on the mosaic layer in the table of contents will only apply to the layer and are not stored with the mosaic dataset, such as the band combination or mosaic method. Therefore, if there are multiple users of the mosaic dataset, they will not be impacted by a layer setting used by another user. This is the same behavior as any dataset and layer.

You can access the Mosaic Dataset Properties dialog box via the Catalog window or in ArcCatalog by right-clicking the mosaic dataset and clicking Properties. Here, you can make modifications to these properties. You can edit the values in the dialog box by clicking the value next to the property. You will either be able to type in a different value or make a selection from a list. You can also use the Set Mosaic Dataset Properties tool to modify the properties.

The properties on the Default tab can also impact the performance of the server or image service if the mosaic dataset is published. When publishing a mosaic dataset using ArcGIS for Server, the server administrator can modify some of these properties as part of the settings on the image service; however, they will not be able to exceed the maximums you have set. For example, if you limit the allowed mosaic methods to only three of the methods, the administrator will not be able to add a fourth method. Or, if you set the maximum number of downloadable items, they can reduce the number but not increase this number. If you change the properties to exceed or limit a value, such as the Maximum Size Of Requests, you need to completely republish the mosaic dataset. If you restart the image service, the changed properties in the mosaic dataset will not be picked up.
