1 Image management solutions for satellite and airborne sensors

2 Overview The Keystone Image Management System offers solutions that archive, catalogue, process and deliver digital images from a vast number of satellites and airborne digital sensors. The Keystone product family caters for evolving needs with systems ranging from a standalone workstation to enterprise-class servers and cloud solutions. Find, view, select and manipulate large volumes of still and motion image material from many sensors in a familiar map context. Enjoy quick and direct access to all your imagery thanks to on-the-fly processing while skipping costly and timeconsuming bulk pre-processing. Maximise the timeliness value of data and make image products rapidly available through network access while keeping multi-sensor archives lean and easy to manage. Scale and extend the Keystone System to meet changing levels and types of demand over time. 2

3 Key Benefits Out-of-the-box capabilities that can be scaled and extended to meet specific needs Keystone can easily be scaled for archives of just a few hundred gigabytes to hundreds of terabytes, while multi-sensor capabilities can be extended using the SOAP-enabled APIs. On-the-fly methods remove the need for bulk pre-processing, leading to rapid access with reduced costs Still and motion imagery are taken almost directly from their sensors with no need for expensive and lengthy pre-processing. Multi-sensor merge is performed on the fly on the output side. Waiting times of hours, days or weeks are reduced to seconds with Keystone. High geometric accuracy achieved through rigorous methods No corners are cut so users can be sure that images served up on-the-fly and ones that are batch processed have the same high quality. Images can be improved using ground control, and sub-pixel accuracy is available when using reference data of sufficient quality.

4 Key Functionalities Catalogue Full context The Catalogue provides full visibility of archived still and motion imagery and its metadata, optimised for fast search and browse. Queries can search any available metadata parameters. Result listings can provide full metadata. Visualise future acquisitions The Catalogue can store information about upcoming data acquisitions. This information can be searched and displayed alongside existing images. Sensor models The Keystone Server ingests imagery from many popular satellite and airborne image sources. Built-in physical sensor models use the image metadata to establish an analytical relationship between the image pixels and Earth coordinate system. This enables geographical searches on all data as soon as it is ingested. New sensors or changed sensor configurations can be added easily. Archive More than storage The image archive maintains the fidelity of high volumes of stored imagery while optimising rapid access for processing. The Keystone Server can ingest both unprocessed and projected imagery, which is stored unadulterated in its original coordinate system. Access Rapid access and interactive visualisation Sensor data is available as soon as it is ingested, providing almost immediate access to new imagery. The Keystone System s on-the-fly processing allows users to interactively design and preview their image products, viewed in their geographical locations at any zoom level. 4

5 On-the-fly image processing Parallel processing Image manipulation and orthorectification is carried out on the fly, removing the need for timeconsuming pre-processing tasks. Performance is maintained through a number of strategies, including parallel processing and caching. 3,000+ coordinate systems The Keystone System supports the EPSG system of over 3,000 coordinate systems worldwide, seamlessly combining and rigorously transforming geospatial datasets between coordinate systems. Unbounded mosaicking Images can be mosaicked on demand to create user-defined products unconstrained by scene or map sheet boundaries. Mosaics can be made using multiple sensors with different spatial resolutions and any number of still and motion imagery frames. Product processing Image factory The Keystone System is optimised for producing high volumes of image products. It handles batch processing as efficiently as it handles complex, precision image creation. Rich products Image products can be generated for a whole scene, for multiple scenes, mosaics or geographical extracts from any of these. Supported product levels range from simple system-corrected imagery to fully ortho-rectified and colour-balanced mosaics. Workflow modification The Keystone Server builds complex processes that allow one or many complex processing steps to be executed. Users can use scripts to customise its functionality to suit specific requirements or streamline workflows. Product distribution Delivery is easy and secure, using FTP and other protocols. Automated notifications to users are easily configured. Accuracy enhancement Pixel precision The Keystone System supports advanced refinement of image accuracy using rigorous physical sensor models and diverse reference material. Automated techniques help streamline this process, including matching to existing reference imagery and the selection of tiepoints in block-bundle adjustments. Administration & user management Security The system administrator can set roles and permissions for any number of users. Access to specific data can be defined on a user-by-user basis. Control Administrators have full visibility of on-going processes such as product generation. They can stop and restart processing tasks and control the number of simultaneous product processes that are supported by the system. 5

6 Keystone family of products The Keystone Image Management System family Keystone Enterprise: Server, Console and Web Portal Server The Server contains the image store, catalogue and the on-the-fly processor. The Server has a service-oriented architecture that is most effectively deployed over a number of networked servers. Many processes are highly parallelised, making best use of multiple processor cores. The system can readily be scaled to support higher levels of throughput or greater end-user load. Console A desktop client that offers full access to the Server s functionality. Streamlined workflows can be created to support the most critical or common tasks. The Console is built on the Eclipse platform, allowing users to add custom plugins. The intuitive map visualisation interface uses the popular World Wind component from NASA. Web Portal Lightweight, browser-based access to the Server s core capabilities. The Web Portal is ideal for providing specific processing and ordering capabilities to a very large or diverse group of simultaneous users. Keystone Enterprise is designed for a multi-user production environment, handling very large volumes of a variety of sensor data types. Products can be published to a multitude of users. Integration with external systems Customers can plug the Server into their current systems using the Keystone API, which provides complete access to the Keystone Server s capabilities for seamless integration into an existing environment. Integration using open standards Users can access the Server using open standards including OGC WMS (Web Mapping Services). This quickly brings the Keystone Server online as a data source within the customer s preferred system or desktop client. Licensing Keystone Enterprise is licensed per installation. The number of users accessing the Server s catalogue and product ordering functions is not limited by licensing. 6

7 of products offers a number of entry points to suit individual business requirements Keystone Solo: a stand-alone alternative Keystone Solo is a streamlined standalone version of Keystone that packages the core capabilities of the image management system into a desktop solution. Keystone Solo supports image production as an interactive, single-user application Keystone Solo is ideal to support small-scale production activities, such as a smaller ground station or field location, with local dissemination of imagery products. Keystone Cloud offers users the core functionality of the Enterprise solution, without the up-front responsibility for installation and maintenance. Sensor data is uploaded to the Keystone Cloud server, where it is hosted together with any image products that are generated. This eliminates extensive in-house with the same advanced modelling tools as the Enterprise solution. It also provides the same fast data access and visualisation through on-the-fly processing and the same range and quality of output products. Keystone Cloud: a carefree solution data storage capacity and production bottlenecks from limited hardware. Products are defined and the process monitored using the Keystone Console client running on a local machine.
