DataMaster provides users with easy to use, reliable tools for processing, exploitation and dissemination of imagery, video, maps, and terrain. The suite of tools allow users to retrieve, convert, and manage image and geospatial information resources from locations around the world, and provide end-to-end geospatial data management solutions that offer flexibility, quality, and performance. It supports multiple client connections simultaneously and manages requests of query, chipping, full extraction, Reduced Resolution Data Set (RRDS) generation or format conversion. The DataMaster server can also utilize a Geospatial Image Access Services Specification (GIAS) interface to broker requests to a Geospatial Imagery Library (NGA), National Imagery Library (NIL) or Command Information Libraries (CIL). We recommend using the DataMaster server for large workgroups, enterprises, or when catalog and archive protection are critical.
