Working with the service table

The service table contains the locations of the raster datasets along with several key properties that make up the image service definition. It is the attribute table of the footprint. Each row in the service table points to a polygon in the footprint shapefile. The service table is generated when the service is created and populated when the raster dataset is added to the service. It is stored along with the image service definition (.ISDef) folder as footprint.dbf.

Viewing and editing service table properties

You can view a service table either by clicking the Open Service Table button 服务表 on the Image Service Definition Editor toolbar or by right-clicking the image service definition group layer in the ArcMap table of contents and clicking Open Service Table from the context menu.

You can add fields to the service table either through the Field Properties node of the Image Service Properties dialog box or by using standard table-editing options. Any changes to the field definitions are saved in the image service definition.

Learn about adding and deleting fields

The metadata fields that can be added are extracted from the raster data based on their raster process definitions (.RPDefs). Metadata fields can also be added by linking to other tables.

Standard fields in the service table

Field

Description

RasterID

The ID number assigned to the raster.

RasterName

Name given to the raster. It need not be unique. It is often the name of the raster dataset.

RasterType

Type of the raster source, either a standard raster dataset type, raster process definition, service overview, or derived tile.

RasterSrc

Source of the raster for the service; points to the raster dataset or raster process definition.

MinPS

Minimum pixel size in meters. If a request is made for a pixel size smaller than this, the raster will not be considered. The value is computed during the build process.

MaxPS

Maximum pixel size in meters. If a request is made for a pixel size larger than this, the raster will not be considered. The value is computed during the build process.

LoPS

Lower pixel size in meters; the smallest pixel size in the raster.

HiPS

Higher pixel size in meters; the largest pixel size in the raster. If the raster has only one grid of pixels, this will be the same as the LoPS value.

DispOrder

Order of display that overrides the order defined by the mosaic method if it is not 0. Values greater than 0 are displayed with lower priority, therefore, the raster dataset may appear below other raster datasets. Values less than 0 are displayed with greater priority, therefore, the raster dataset may appear on top of the other raster datasets.

StatusID

Status ID. Status updated by the build process that indicates when there is a warning or error related to the raster. A positive value indicates a warning. A negative value indicates an error. A value of 0 indicates that the operation was successful.

StatusMsg

Status message. This is a descriptive message associated with the statusID.

Service table options

When the service table is opened, it functions as any other table in ArcGIS. You can select records, view only selected records, move columns around, sort in descending or ascending order, freeze columns, add fields, create a graph, export the table, and more. All these options are available by right-clicking the column heading, selecting particular columns or rows, or clicking the Options button.

When the service table is opened, the position and width of the fields are reset to those defined in the service table properties.
