Geospatial imagery is the foundation of most mapping and GIS technology. Management of rapidly expanding catalogs of imagery from sources such as digital cameras, satellite imagery, and digital terrain models, is essential.
ArcGIS provides an enterprise-wide image distribution and processing platform that supports multiple workflows associated with collection, management, production, and analysis of imagery. This includes the ability to serve large volumes of imagery quickly through dynamic, server-side image processing. High-performance image services serve raster data and provide control over imagery delivery from wherever it is required. ArcGIS Server Image extension provides efficient access management and processing to large numbers of images.Image services are similar in concept to map services but are optimized for imagery (are faster) and provide additional capabilities for image exploitation. Image services are a core service available with ArcGIS Server.
