  1. Distributed Systems RAMSES Regional Earth Observation Application for Mediterranean Sea Emergency Surveillance System Suchitra Vijayakumar Background - Berlin

  2. Agenda • Introduction • RAMSES • Goals • Objectives • Architecture • Languages • Purposes • Aspirations

  3. Introduction • Earth observation application system • Oil detection on Mediterranean sea • Develop and validate a system • Effectiveness of distributed environment • Business network composed of components • Platform independency and expandability • Technologies used are CORBA and JAVA

  4. RAMSES Actors • End to End EO Application • Data Level • Information Level • End to User Level

  5. Terms • Data providers • Value adders • Scientific institutions • Business intermediaries • Customers • Operational end user • Research and Development

  6. Infrastructure Topology

  7. Infrastructure Topology • Classical three tier computing system • DP server • Central Server • SI Server • Web Server • Communication • SIS and CS – Internet • CS and DPS – 128KB ISDN link

  8. DP Server Architecture

  9. Central Server Architecture

  10. Purposes • Oil slick forecast and hindcast models • Automatic oil slick detection algorithm • Ship and position forecast models • Reusability, expandability and scalability • Semantic relationships between components

  11. Conclusion • In the beginnings – initial research • Understanding of the benefits of space based earth observation • Component oriented three tier architecture was investigated based on CORBA • Allocate specific functions to different service providers
