About the service table

The service table acts as a catalog of the raster datasets that make up an image service definition. Each raster dataset included in an image service definition is referenced by one record in the service table. The service table is stored as part of the footprint shapefile within an image service definition, with each raster dataset being represented by a footprint. The service table includes a number of fields that provide information about the raster dataset. Some fields in the service table control how raster datasets should participate in the image service definition, such as the display range, status information, and different metadata.

The service table contains the following fields:

Additional fields can be defined in the service table or linked. Typically metadata fields, such as date, cloud cover, or quality of the raster dataset, are defined for raster datasets. When such metadata fields are defined, these fields can be used in conjunction with the By Attribute mosaic method to enable a client application to order the imagery as required. Other metadata fields can also be added to enable simplified management of the large number of raster datasets that can exist within an image service definition.

Altering service table fields

The fields defined in the service table are controlled using the Field Properties node on the Image Service Properties dialog box. The Field Properties node can be used to add and remove fields and control how fields are displayed. Additionally, if the fields are defined using field properties, metadata can be extracted from the raster process definitions when the image service definition is built.
