Description
An image service provides access to raster data through a web service. Multiple rasters can be served as one image service through mosaic dataset technology, dynamically processed and mosaicked on the fly. An image service supports accessing both the mosaicked image and its catalog, as well as individual raster in the mosaic.
An image service supports dynamic access and tiled access. Dynamic access provides much more functionalities and tiled access provides faster access to pre-rendered pictures.
The map service resource supports the following operations
Basic raster information including its spatial reference, extent, pixel size, pixel type, number of bands, and band statistics, thumbnail, key properties, and metadata can be access for the entire mosaic as well as individual rasters (through Raster Catalog Item).
The REST API image service resource represents an image service published with ArcGIS Server. The resource provides basic information associated with the image service such as the service description, its name, description, extent, pixel sizes, and band counts.
From 10 onwards, this resource also returns the accessible fields, timeInfo of the image service.
option and outSR to support viewing of a Image service footprint in arcgis.com.From 10.1 onwards, this resource also includes the following:
initialExtent, fullExtent, singleFusedMapCache, tileInfo properties that indicate cache information of the service.
defaultMosaicMethod, mosaicOperator, defaultCompressionQuality, defaultResamplingMethod properties that indicates service defaults. The default mosaic rule is composed of defaultMosaicMethod and mosaicOperator. When defaultMosaicMethod is esriMosaicAttribute, image service uses sortField and sortValue along with it.
allowRasterFunction, allowedMosaicMethods, maxRecordCount, maxImageHeight, maxImageWidth, maxDownloadImageCount,maxDownloadSizeLimit, maxMosaicImageCount properties that indicates service contraints.
rasterFunctionInfos, rasterTypeInfos, mensurationCapabilities properties that indicate supported raster function templates (for exportimage), raster types (for add/update rasters), and mensuration capabilities (for mensuration).
hasHistograms, hasColormap, hasRasterAttributeTable properties that indicate if a corresponding resource is available for the service.
capabilities properties that indicates supported operations.
editFieldsInfo and ownershipBasedAccessControlForRasters containing editor tracking and access control related properties.

Parameters
| Parameter | Details |
|---|---|
| f | Description: The
response format. The default response format is html. Values: html | json | kmz | lyr |
| option |
//This parameter was added at 10.1 Description: If option is footprints the footprint of the image service is returned as a feature collection. This feature collection can be viewed in a arcgis.com map. This is supported when f=json only.Value: footprints |
| outSR |
//This parameter was added at 10.1 Description: The spatial reference of the geometry returned in footprints. This parameter is supported only when option=footprints is specified.
The spatial reference should be specified as a well-known ID. If outSR
is not specified, the geometry is returned in GCS_WGS_1984. |
Example Usage
Example 1: URL to an Image Service named "MyImage".

"description": "This service hosts a raster image generated from raw DEM (Digital Elevation Model) data gathered for the Shuttle Radar Topography Mission (SRTM). The mission was co-sponsored by the National Aeronautics and Space Administration (NASA) and National Geospatial-Intelligence Agency (NGA). NASA's Jet Propulsion Laboratory (JPL) performed preliminary processing of SRTM data and forwarded it to the NGA for further processing and distribution. The raster image hosted by this service was generated using ArcGIS tools to convert DEM data for the state of California into a raster image. The results were reprojected into World Mercator (WKID: 54004) for display purposes. Pixel size is approximately 90 meters and vertical units are defined in meters. ESRI reserves the right to change or remove this service at any time and without notice. Copyright: Copyright:© 2010 ESRI ",
