4. Making Location Count... OGC’s Approach for Advancing Interoperability Interoperability Program (IP ) - a global, innovative, hands- on rapid prototyping and testing program designed to unite users and industry in accelerating interface development and validation, and the delivery of interoperability to the market Specification Development Program –Consensus standards process similar to other Industry consortia (World Wide Web Consortium, OMA etc.). Outreach and Community Adoption Program – education and training, encourage take up of OGC specifications, business development, communications programs Compliance Testing and Certification Program - allows organizations that implement an OGC standard to test their implementations with the mandatory elements of that standard 4 Copyright © 2011 Open Geospatial Consortium

5. OGC ® OGC Interoperability Program Proven process to rapidly develop, test, validate and demonstrate new standards based on real world use cases identified by OGC members Effective way for members to quickly align industry to advance standards to meet priority needs Efficient and competitive process, regularly yielding a high-level of industry participation and cooperation Repeatable process – over 30 initiatives successfully conducted using proven policies and procedure 5Copyright © 2011 Open Geospatial Consortium

7. OGC ® Interoperability Program Interoperability Initiatives Testbeds are fast-paced, multi-vendor collaborative efforts to define, design, develop, and test candidate interface and encoding specifications. These draft specifications are then reviewed, revised, and, potentially, approved in the OGC Specification Program. Pilot Projects apply and test OGC specifications in real world applications using standards based commercial off-the-shelf (SCOTS) products that implement OGC Specifications. Interoperability Experiments are brief, low-overhead, formally structured and approved initiatives led and executed by OGC members to achieve specific technical objectives that further the OGC Technical Baseline.

42. OGC ® CONCLUSION 42Copyright © 2011 Open Geospatial Consortium

43. OGC ® Accomplishments Another successful OGC Interoperability Program Initiative, despite having to work around scope and requirements changes due to SAA source data limitations –Cooperation and coordination among multi-national participants Academic institutions Aeronautical information technology companies Commercial GIS product development representatives –Consistent and responsive contributions and support from FAA participants and representatives –Special thanks to Johannes Echterhoff in leading this effort, in recognition of his organizational, management, and note-taking skills 43Copyright © 2011 Open Geospatial Consortium

44. OGC ® Accomplishments Implemented support for AIXM 5.1 in OGC standards based web service components Mapped AIXM 5.0 data into AIXM 5.1 Supported AIXM 5.1 temporality model Supported SAA AIXM schema extension Tested the draft Digital NOTAM Event Specification Implemented WFS and ES support for complex airspace geometries, aggregated airspaces, and improved filter capabilities in spatial queries Interfaced WFS and ES with available data sources via adapter components Implemented support for portrayal of AIXM 5.1 data (via WMS, FPS and Registry) Time-dependent map display styling Demonstrated the value of geospatial and temporal data fusion for the display and use of airspace activation data in realistic aviation scenarios 44Copyright © 2011 Open Geospatial Consortium

45. OGC ® Lessons Learned 45Copyright © 2011 Open Geospatial Consortium Implemented AIXM / OGC standards are mature enough for industry adoption OGC, GML and AIXM standards clarifications Draft standards need to be finalized (e.g. Event Service) Using OGC Web Services for SAA data dissemination Integration of static and dynamic data (via WFS) enables value added functions such as airspace proximity notification Retrieving static and dynamic AIXM data from a single source (WFS), fine grained retrieval of AIXM feature timeslices needs work Support for snapshot timeslices is important for decision support scenarios Demonstrated usefulness of time dependent, greater than 2D portrayal of SAA information Challenges Having more stable requirements and established data standards would facilitate integration efforts, especially with short-duration initiatives Data quality does not yet meet requirements for productive use, SAA data has to be validated for consistency before being disseminated

46. OGC ® Value Added Aviation Industry –Demonstrated value of OGC open standards compliance in facilitating cost-effective multi-vendor tool integration –Standards-based approach makes interface implementation viable –Demonstrated support for both lightweight, browser-based client visualization including cross-section perspective, and thick client tools with more advanced data analysis and rendering –Implemented architecture can better address realistic flight data decision support requirements and at the same time potentially reduce the number of cases of non- compliance of airspace users –Offers enhanced pilot situational awareness for onboard systems –Provided insight to industry on what changes are required to take advantage of AIXM compliant data disseminated via OGC web services FAA –Created a single consolidated source of SAA data for dissemination using OGC- standard web services and AIXM message formats –Beta test of AIXM-format airspace definitions and AIXM 5.1 SAA extensions –Utility of consolidating separate VFR images into single VFR chart display 46Copyright © 2011 Open Geospatial Consortium

47. OGC ® Future Directions Industry Standards –Further evolution and refinement of AIXM temporality model conventions and guidelines to enable more practical and efficient implementations –Automate SAA business rule constraint processing (using schematron) –Use of WFS 2.0 pre-defined queries to support SAA data analysis and notifications AIM Systems –Explore OSGi deployment of OGC service components using a common FUSE ESB –Refinements to AIM systems and service architectures in the context of consolidated static+dynamic AIXM feature representations –Extend architecture to support end-to-end management (including editing, adding and approval) of SAA information in the system –Test integration of SWIM-based SAA services with OGC service components –Performance benchmarking and assessment of comparative architecture scalabilities 47Copyright © 2011 Open Geospatial Consortium
