Web-Enabled Access to Synthetic Aperture Radar (SAR) Metadata for Enhanced Analysis

This project aims to solve the challenges posed by Lockheed Martin Company (LMCO) in accessing and analyzing Synthetic Aperture Radar (SAR) metadata. Currently, SAR metadata is stored in binary flat files, limiting access and analysis capabilities. By developing a relational database management system (RDBMS) solution with web-based access, the project seeks to facilitate broader employee access to detailed data, enhance information dissemination, and improve the efficiency of data storage and retrieval. Keywords include platform independence, improved data management, and advanced analysis workflows.

  1. Java Web-Enabled Access to Metadata Team Members: Bill Busby, Lindsey Gray, & David Meffe Project Sponsor: Lockheed Martin Co.

  2. Main Points • Problem Statement • Requirements and Goals • Product/Solution Statement • Storage/Retrieval • Web-based Display • Risks Bill Busby

  3. Problem Statement: Background/History • LMCO premier producer of Intelligence, Surveillance, and Reconnaissance (ISR) systems • Used by U.S. and allies for: • fixed target imaging (FTI) • moving target indications (MTI) • automatic target recognition (ATR) • battle damage assessment (BDA) Lindsey Gray

  4. Problem Statement: Background/History (cont) • Synthetic Aperture Radar (SAR) metadata imagery used in reprocessing and post-processing procedures and analysis • LMCO produces over 75% of world’s SAR systems. Lindsey Gray

  5. Problem Statement:Business Issues • need for web-based access and analysis of SAR metadata • Facilitate information dissemination • need for improved data storage/retrieval • Currently stored as binary flat files • inadequate to support web-based access and analysis • creates platform dependence Lindsey Gray

  6. Problem Statement: Value of a Technology Solution • Web-based access and analysis • more employees have more access to more detailed data • create platform independence • Relational database management system (RDBMS) & structured query language (SQL) will provide faster access and better support. Lindsey Gray

  7. Problem Statement: Competitive Products • No competitive products available commercially • Requires custom solution due to data security issues and desire to use new emerging technologies Lindsey Gray

  8. Problem Statement:Business Environment • Information is crucial to making decisions. • Customers requested web-based access to this information • Metadata derived from SAR images and used in reprocessing and post-processing algorithms. • The security issues regarding access to SAR metadata is the responsibility of Lockheed-Martin Co. and is not within the scope of this project. Lindsey Gray

  9. Requirements Overview • Goals • Design & build an improved storage model • Design & implement a method for web-based access • Requirements • Functionality • Operational environment • Users David Meffe

  10. Goal: Design & Build an Improved Storage Model • Reason • Lockheed-Martin is currently storing synthetic aperture radar (SAR) metadata in flat file format and require a more efficient method of storing data. • Benefits • Platform independent • All data is stored • Locate data faster using queries David Meffe

  11. Goal: Design &Implement a Method for Web-based Access • Reason • Lockheed-Martin wants to access the synthetic aperture radar (SAR) metadata through a web-based environment • Benefits • Multiple user access to data • Common display method for SAR imagery David Meffe

  12. Requirement: Functionality • Provide web-based access to synthetic aperture radar (SAR) metadata • Storage and retrieval of SAR metadata in a database • Query database for SAR metadata • Insert SAR metadata in database using Extensible Markup Language (XML) parser routine David Meffe

  13. Requirement: Operational Environment & Users • Operational environment • Initially Windows NT • Accessible through internet browser • Internet Explorer • Users • Range from beginner to advanced • Online help facility • Intuitive user friendly interface David Meffe

  14. Product/Solution Statement Project can be divided into 2 main areas: • Data storage/retrieval model • Web-based display of data Bill Busby

  15. Storage/Retrieval Model • RDBMS – Oracle8i • Need to limit access • Different views for different user types • Data retrieval via JDBC Bill Busby

  16. Web-based Display • Format Data • 3 documents for using XML • XML • DTD • XSL or CSS • Dynamic generation of content • JSP and/or Servlets Bill Busby

  17. Risks • Learning new emerging and changing technologies • XML • JSP • No actual data, just placeholder tags • Lack of details • User Environment • Data Bill Busby

  18. Conclusion • SAR Metadata • The Opportunity • Improved storage/retrieval model • Web-based access • Tools for the Solution • Oracle8i • XML • We are the ‘JWEAM Team’ Bill Busby
