Maintenance

Maintenance of mosaic datasets and image services typically involves the addition of new imagery. With the pattern of creating source and derived mosaic datasets, this requires both to be updated. There are three ways in which source mosaic datasets are updated:

  1. Adding the rasters to the original source mosaic dataset—Typically, the same raster type used to originally add data is used to add new data.
  2. Running the Synchronize Mosaic Dataset tool on the source mosaic dataset—This reruns the originally used raster types and will add or update parameters of any new sources in the original workspaces. You need to be aware of the parameters you set, because this tool can also overwrite some of the changes you may have made to the items in the mosaic dataset. For specific information, see Synchronizing a mosaic dataset.
  3. Using a new source mosaic dataset—In this case, a new source mosaic dataset is created to reference the new images.

Once the source mosaic dataset is updated and checked, there are two methods by which the derived mosaic datasets are updated:

Referenced mosaic datasets do not need to be updated (or re-created), as they reference the derived mosaic datasets. The exception is if the boundary of the services needs to be changed.
