The ArcGIS Image Server adds raster data to image services by specifying raster types. The raster type helps the server identify metadata, such as georeferencing, acquisition date, and sensor type, along with a raster format.
A raster format defines how pixels are stored, such as number of rows and columns, number of bands, actual pixel values, and some other raster format-specific parameters. However, by adding raster data according to a raster type, the ArcGIS Image Server knows what metadata to read and how it should be used to define any processing that has to be applied. After selecting the specified type of raster, the program will prompt for additional information that is pertinent to that raster type. For example, when adding a QuickBird Standard scene, a scene is defined by an .imd file. The .imd contains metadata information about the raster dataset and may point to one or more .tif files. You are then prompted to choose additional information that is available because of the .imd file, such as the band combinations or whether you want the output to have panchromatic sharpening.
When you choose to add raster data to your image service, the Select Raster Type dialog box is displayed. There are three folders in this dialog box where most of the raster types are located—Elevation, Georeferenced Imagery, and Orthorectification. Each of these and the raster types are described below.
To learn more about adding raster data, see Adding and removing raster data in a service.
Third-party developers can also create .RPDef files for direct use in ArcGIS Image Server.
Georeferenced imagery raster types
This category of raster types includes raster types that have already been georeferenced or have associated files that will assist in georeferencing the raster data.
| Raster type | Description | Extensions |
| Compressed ARC Digitized Raster Graphics (CADRG) | Distributed on CD-ROM by the National Geospatial-Intelligence Agency (NGA). CADRG is geographically referenced using the ARC system in which the globe is divided into 18 latitudinal bands, or zones. The data consists of raster images and other graphics generated by scanning source documents. | Single file—no standard file extension.
Add your extension in the Filters text box when using this raster type. |
| Controlled Image Base (CIB) | Panchromatic (grayscale) images that have been georeferenced and corrected for distortion due to topographic relief distributed by the NGA. Thus, they are similar to digital orthophoto quads and have similar applications, such as serving as a base or backdrop for other data or as a simple map. | Single file—no standard file extension.
Add your extension in the Filters text box when using this raster type. |
| Digital Geographic Information Exchange Standard (DIGEST)
ARC Standard Raster Product (ASRP), UTM/UPS Standard Raster Product (USRP) |
DIGEST datasets are digital replicas of graphic products designed for seamless worldwide coverage. ASRP data is transformed into the ARC system and divides the earth's surface into latitudinal zones. USRP data is referenced to UTM or UPS coordinate systems. Both are based on the WGS 1984 datum. | Multiple files
