Exporting imagery from an image service in Image Server Viewer

The data you received as a client from an image service can be exported as a raster dataset and saved on your local system. You might need to save this data to use it in GIS analysis applications. You cannot export the raw data used to create the service; you can only export the data you receive as a client—that is, the processed raster data. You can save this data in TIFF, JPEG 2000, JPEG, and PNG file formats. The maximum size of images saved is controlled by the administrator.
