ArcGIS Image Server allows you to manage and process huge volumes of raster data and provides enterprise-wide access within GIS, CAD, imaging, and Web applications. Traditionally, image processing and distribution have been considered two separate stages in image exploitation. This separation causes data redundancy, explodes volumes of data, and hinders efficient data management. With ArcGIS Image Server, these two stages can be combined, enabling the administrators of data to maintain only the primary imagery with multiple image products created instantly, on the fly, as required by users. By improving on the traditional workflow for image management and distribution, ArcGIS Image Server can reduce costs and improve efficiency by

ArcGIS Image Server enables the creation of image services that can include large numbers of image datasets, in different formats, projections, and at different resolutions. One of the key features of ArcGIS Image Server is that it supports image data in its native format and does not require a special format to be created. The data may be a preprocessed product, such as tiled orthoimagery; semiprocessed data, such as georeferenced but overlapping orthoimagery; or primary data, such as raw scanned frames or satellite images. The data can be in different compressed or noncompressed file formats or in a DBMS. ArcGIS Image Server supports all ESRI supported raster formats, such as geodatabase rasters, TIFF, and JPEG 2000, as well as specific vendor outputs such as QuickBird, USGS DEM, and MATCH-AT. Utilizing the server's processing power, multiple image products can be generated from a single data source, each with different radiometric processing, geometric processing, mosaicking rules, and compression options.

Image services are published through ArcGIS Server to direct connect network clients (using remote procedure calls [RPC]); to Web clients (using Hypertext Transfer Protocol [HTTP]); and as Open Geospatial Consortium, Inc. (OGC), Web Map Services (WMS) or OGC Web Coverage Services (WCS). Image services are also accessible using Simple Object Access Protocols (SOAP). Clients can connect directly through ArcGIS Desktop applications and third-party applications, such as AutoCAD and MicroStation, or using Web clients such as ArcGIS Explorer. Direct connect clients can also be served directly by ArcGIS Image Server stand alone.

Clients connect to ArcGIS Server and see each image service as a single virtual mosaic, although it could be created from large numbers of individual images. As the client pans or zooms around, the server extracts and processes the required data, providing a final mosaicked image to the client application. Both the data access and processing is highly optimized, making the time from request to image display nearly instantaneous.

ArcGIS Image Server is not a GIS or an image analysis application but the backbone for georeferenced imagery required by many applications. Scalable and designed to handle thousands of images simultaneously, ArcGIS Image Server can handle huge quantities of images, now and in the future.

Sample applications

ArcGIS Image Server can be used to exploit the high value of raster datasets for a range of applications including
