Description
An image service provides read-only access to a mosaicked collection of images or a raster data set.
Use an image service to do the following:
- Get image service information, including its native spatial reference, extent, pixel size, pixel type, number of bands, and band statistics
- Generate an image
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.
The image service resource supports only one operation export image, which returns an image resource.
