OGC at a Glance (1)
The Open Geospatial Consortium (OGC) is a non-profit, international
voluntary consensus standards organization that is leading the development,
promotion and harmonization of standards for geospatial and location based
services.
• Founded in 1994, not for profit, consensus based and voluntary
• Over 416 member organizations (industry, government, academia) (January 2011)
http://www.opengeospatial.org/ogc/members
• 30+ adopted OGC Standards (some are ISO Standards)
http://www.opengeospatial.org/standards
• Several hundred software products, implementing OGC Standards
http://www.opengeospatial.org/resource/products
• Broad user community worldwide, many policy positions for NSDI based on OGC
standards
• Cooperation with other standards organizations and foundations, e.g. ISO, W3C, OMG,
etc http://www.opengeospatial.org/ogc/alliancepartners

OGC’s Approach for Advancing Interoperability
• Interoperability Program (IP) - a global, innovative, handson 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.).
• Compliance Testing and Certification Program allows organizations that implement an OGC standard to
test their implementations with the mandatory elements of
that standard
• Outreach and Community Adoption Program –
education and training, encourage take up of OGC
specifications, business development, communications
Making Location Count...

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

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.

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

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

44
Lessons Learned
• 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

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 noncompliance 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 OGCstandard 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

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
