  2. Opticks – Journey To Open-Source • Overview of Opticks • Why Did We Open-Source? • The Hurdles • Where are we today? • Q & A

  3. Overview of Opticks • Perform Image and Video Analysis • Spectral, Synthetic Aperture Radar, Thermal • Similar to the following commercial tools: • SOCET GXP, IMAGINE, RemoteView, ENVI • Extendable with plug-ins: • Add import/export support for new file formats • Implement new data processing algorithms • Add new windows, mouse modes, toolbars, keyboard shortcuts • Most of the application is implemented as extensions using our public extension API

  4. Why Did We Open-Source? • Project was started as closed source in Spring 2000 for the Air Force • Why Open-Source? • Kept running into barriers to entry for others to develop plug-ins • COTS (Commercial Off the Shelf) is preferred over GOTS (Government Off the Shelf) • Not invented here • What does open-source provide us? • Increase in services business opportunities • Access new customers and/or new markets • Involvement with and support for the DoD’s OTD (Open Technology Development) Roadmap • Actively engage colleges and universities in remote sensing processing and explotation

  5. The Hurdles • Internal Confusion/Conflicts about going open-source • Contracted with CollabNet for their open-source expertise to help resolve some of the mis-information • What did our Air Force customer think? • Worked with our customer from the beginning to get buy-in • Do we have the right kind of software to open-source? • OTD Roadmap calls out “geospatial framework/infrastructure” • What about ITAR? • Reviewed internally, determined it was a Defense Article (Category XXI – Miscellaneous Articles), requested Public Release Authorization from the Office of Security Review • What license should we use? • LGPL v2.1 • Allowed plug-ins to be closed-source • Keeps the application open-source (even if forked) • Well known license (one less hurdle when people are looking to adopt)

  6. Where are we today? • Opticks was released under the LGPL v2.1 in December 2007 • http://opticks.org/ • All development is now free and open (no entry criteria) • Both source code and development collaboration • Remaining Issues • Decided internally to continue vetting all new features/enhancements against ITAR before starting code development (all code development is still occuring in the open) • Getting government people to collaborate with us in the open • In the process of standing up software.forge.mil mirror of Opticks to lessen the blow for new government entrants • Balancing open-source community needs against paying customer needs
