Rapid Uptake of Image Server
Users Dynamically Process and Quickly Distribute Imagery
Since its release a year ago, ArcGIS Image Server has made a dramatic impact on the way GIS users are managing, processing, and serving imagery to their users. A complete enterprise solution, ArcGIS Image Server is fundamentally redefining how imagery is processed and distributed to end users. ArcGIS Image Server is unique in its ability to combine both on-the-fly server-based image processing with distribution to any client. It provides enterprise-wide access to very large image datasets within GIS, CAD, imaging, and Web applications, allowing users to manage, process, and quickly serve large quantities of raster data for visualization and analysis to a variety of clients.
Traditionally, image processing and distribution have been considered two separate stages in image exploitation. This separation radically slows down processing, causes data redundancy, increases the amount of data that must be stored, and hinders efficient data management. Using ArcGIS Image Server, bottlenecks in conventional image-processing workflows can be resolved because raster datasets can be stored directly as files on servers, then processed and distributed at once without extensive preprocessing, conversion, or loading of the data into a database.
On-the-fly processing enables high-resolution georeferenced imagery to be distributed and made available to end users in a timely manner upon acquisition. This fast access to imagery reduces the latency between image capture and usage, thereby maximizing the value of imagery.
Users can tap into the server's processing power to generate multiple image products from a single data source, each with different radiometric processing, geometric processing, and compression options. These processes maximize the depth of the imagery and eliminate data management problems associated with multiple preprocessed datasets. This can substantially reduce data storage requirements. Server-side processing also enables access to raster data from thin client applications, thereby trimming down requirements for workstations that access and process the data.
Also for Preprocessed Image Products
ArcGIS Image Server is also being used by organizations that have large volumes of preprocessed or tiled imagery. Traditionally loading and maintaining such datasets have been difficult as the data often resides with multiple formats, projections, dates, and locations. This has required huge effort and time in processing and mosaicking the products into single seamless datasets. With ArcGIS Image Server, these datasets can be easily combined into image services with all conversion, reprojection, and mosaicking being performed on the fly.
Instant Return on Investment
ArcGIS Image Server provides value to any organization involved in image processing and/or distribution. By reducing data storage costs and reducing manpower required for data processing and maintenance, ArcGIS Image Server gives users an instant return on investment.
The immediate value of ArcGIS Image Server is derived from
ArcGIS Image Server can scale to manage increasing demand and provide new functionality as imagery needs evolve. Image requests are passed to multiple service providers to support effective load balancing. Because additional service providers can be added as requirements increase, ArcGIS Image Server can scale to support very large processing demands. Additionally, optimized indexing enables ArcGIS Image Server to simultaneously serve many concurrent image requests by processing only the pixels required for a client's display. This reduces transmission data and frees ArcGIS Image Server for additional requests.
By supporting a scaling architecture, as well as additional program functionality through extensions and an included software developer kit (SDK), ArcGIS Image Server can meet the needs of both small organizations and large enterprises.
Operating System and Imagery Integration
ArcGIS Imager Server operates on low-cost Windows hardware and requires no special technology. ArcGIS Image Server is part of a complete integration of imagery into the core of the ArcGIS platform. At ArcGIS 9.3, Image Server is being fully integrated with ArcGIS Server and will be sold as an optional extension. This integration supports more seamless integration of imagery in ArcGIS and a broader set of standards for access.
