3. OGC’s Approach for Advancing Interoperability
Interoperability Program (IP) - a global, innovative, hands-on rapid prototyping and testing program designed to accelerate interface development and validation, and bring interoperability to the market
Demo &
Reports
Specification Development Program – Consensus standards process similar to other Industry consortia (World Wide Web Consortium, OMA, etc.)
These interoperability initiatives are a crucial part of OGC’s overall strategy for identifying, developing, and maturing standards that serve the needs of government, industry, academia and the research community. In the past 10 years, we have conducted more than thirty interoperability initiatives, each resulting in realistically tested requirements and prototype designs for new or enhanced interoperability standards.
The output from each of these initiatives includes the prototype applications, schemas and services developed and demonstrated. But more importantly, the output also includes numerous engineering reports, documenting the architectures and software developed, along with lessons learned, and proposals for further work. These reports contribute to OGC‘s library of Best Practices, and recommendations to working groups within OGC‘s Specification Program.
Once Best Practices and Standards have been approved and adopted by vote of the OGC membership, they are published for free and open access to the public. It is important to note that OGC‘s intellectual property consists of the interface specifications for data exchange, not the details of each organization‘s implementations of software. In this way, these standards enable the marketplace of tools and techniques to grow and adapt to ever-changing business and technology conditions.
Outreach and Community Adoption Program – education and training, encourage take up of OGC specifications, business development, communications programs

Security and secured services within and across domains
Enterprise-oriented scenarios (gov/mil/large corporation)
Refinement of process integration and service chaining
Threads
SWE (Sensor Web Enablement)
Imagery services, information models, CCSI, catalog
GPW (Geo-Processing Workflow)
Asynchronous workflow, WPS grid processing, GML schema development
DSS (Decision Support Services)
WMTS, 3D indoor-outdoor routing / tracking, W3DS, flythrough client, integrated client, ISO 19117/SLD portrayal
AIM (Aeronautical Information Management – new thread)
Service orientation, AIXM, notifications, and flight operations
CITE (Conformance and Interoperability Test & Evaluation)
Complete WMS 1.3, and DGIWG Profile of WMS
As before, OWS-6 builds on the results of the previous testbed, OWS-5, which addressed geoprocessing workflow, sensor web interfaces, and decision support services. For this testbed, the sponsoring organizations wanted to start applying the sensor web and geoprocessing interfaces within enterprise frameworks for web-based event notifications and secure access control, applying and adapting current Information Technology practices to work with geospatial and temporal data. For decision support, a number of geospatial information servers and client applications were extended to integrate legacy capabilities with new data sources in meaningful ways, within the enterprise security regime.
OWS-6 also initiated a new thread of activity in the field of aviation information management, looking at ways to apply web services and related technology to greatly improve flight operations.
The fifth or CITE thread is different from the others. Its purpose is to develop robust tools and scripts for certifying that a given software product correctly implements a given standard. Each OWS cycle seeks to extend the library of certifications available to the marketplace, according to current priorities of the sponsoring organizations.

5. Aeronautical Information Management (AIM)
New Thread for OWS-6 sponsored by FAA and Eurocontrol
Develop and test standards-based service-oriented architecture to support the provision of valuable aeronautical information directly to flight decks and Electronic Flight Bags (EFB)
Support vision for Aeronautical Information Management
Interconnected systems with many actors and many users
Need for real-time information used in flight planning, navigation, rerouting, etc
Right information at the right time at the right place to the right user
End-to-end management of information
For AIM, the objective was to provide relevant aeronautical and weather information directly to flight decks and Electronic Flight Bags via a standards-based service oriented architecture, that can support a vision of future Aeronautical information management where many users need access to the information for flight planning, navigation, and rerouting and where it’s critical that the right information is provided to the right user at the right time at the right place. The basis for this future concept of operations and the transition to a net-centric global aeronautical management capability is AIXM.

6. Aeronautical Information Exchange Model AIXM 5.0
Develop and demonstrate the use of AIXM 5.0 in an OGC Web Services Environment
Evaluate and advance various AIXM 5.0 characteristics in realistic scenario setting
AIXM is the Aeronautical Information Exchange Model, jointly developed by FAA, Eurocontrol and NGA as a global standard for the representation
And exchange of aeronautical information. AIXM 5.0 is based on the ISO series of geospatial information standards including the use of
Geography Markup Language (GML).
In OWS-6, the objective was to test, demonstrate, evaluate and advance the use of AIXM 5.0 in an OGC Web Services Environment
In particular addressing the fact that all aeronautical features can change over time and have a start of life and end of life.

7. OWS-6 AIM Goals: Right Data, Right Time, Right Place
Use and enhancement of Web Feature Service and Filter Encoding specifications in support of AIXM 5.0 features and 4-D flight trajectory filtering,
Architecture and demonstration of standards-based Event Alert mechanism to notify users of changes to selected relevant aeronautical information,
Prototype of Aviation Client(s) for retrieval, integration and visualization of AIXM and Weather data based on relevant and up-to-date information in relation to a flight

The AIXM WFS was accessed by our Aviation Clients to retrieve full and updates AIXM data in relation to a flight plan:
Carbon Project: next generation EFB prototype developed using the CarbonTools toolkit based on the .NET presentation and communication frameworks. Luciad:  AIM Client built using LuciadMap’s suite of software components for high performance visualization of geospatial information PCAvionics: Extension to MountainScope, a portable system of moving color maps and high-resolution terrain graphics for flight planning and routing Lufthansa systems: Enhancement for the LIDO eRouteManual, a fully approved charting software with moving enroute map
For the weather data, the clients connected to two Web Feature Services one provided by the Next Generation Weather Network NNEW, providing access to hourly METAR Aviation Routine Weather Reports and TAFs Terminal Aerodrome Forecasts. The other WFS was an experimental WFS provided by NOAA providing access to TAF data using the emerging Weather Information Exchange Model (WXXM) standard.
An Event Service provided by University of Muenster supported the brokering of events between event publishers and the aviation clients.

9. U of Muenster Event Service
The Event Service held a collection of subscriptions where new subscriptions of clients are added. Each of these subscriptions contains a filter statement to define the notifications of interest and and end-point where the notifications are to be sent. The filters were encoded as draft FE 2.0 filters and The endpoints were specified using OASIS Web Service addressing.
When a notification or event is posted by a publisher, the filters are applied to the subscriptions to determine who to forward the notifications to. Only notifications matching a subscriber’s criteria are forwarded to that subscriber.

Demonstrates the ability of Web Feature Services (WFS) and the Filter Encoding (FE) Specification to distribute aeronautical data in AIXM 5.0 format in response to direct user queries or in response to alerts to a user when specific aeronautical information – as defined by that user – is updated
Alternate
Destination Airport
ATL O
To demonstrate the work, we developed a short video based on a fictitious but realistic scenario to show you how the AIM technologies tested in this testbed can aid the pilot in decision making.
Flight OWS 123 is going from Dallas Texas to Orlanda Sweden with Wilmington Ohio being the diversion airport. Because the diversion airport ends up being closed due to bad weather, Atlanta International is selected as the new diversion airport. Unfortunately, it turns out that Orlanda is closed so the pilot ends up landing the plane at Norkopping the alternate airport.
The video you will see is a collage of videos developed by the participants. The original detailed videos of each participant will be featured on the OWS-6 DVD and webpage. So make sure you don’t miss them! O
