OGC at a GlanceOGC at a Glance

• 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

A non-profit, international voluntary consensus standards organization that is leading the development, promotion and harmonization of publicly available, open standards for geospatial and location based services.

OGC’s Approach for Advancing InteroperabilityOGC’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 delivery of interoperability to market

• Specification Development Program –Consensus standards process similar to other Industry consortia (World Wide Web Consortium W3C, OMG etc.).

• Marketing and Communications 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 mandatory and optional elements of that standard

Advance interoperable data retrievalAdvance interoperable data retrieval

• Continuing provision of AIXM and DNOTAM data via WFS and Event Service

• Addressing complexity of creating expressions to filter AIXM data through advanced filtering functionality:– Non-spatial feature query– AIXM feature as geometry operand– Stored Query / Filter– Selective metadata retrieval– Subscription update intervals – Altitude query (for airspaces)

• Representation, management and provision of AIXM metadata, especially provenance metadata

• Conform to Aviation metadata requirements & guidance– Requirements for Aviation Metadata (OGC 10-195)– Guidance on the Aviation Metadata Profile (OGC 10-196r1)

• Investigation of alternative approaches for efficient metadata management– Efficiency factor / objective: minimize bandwidth consumption, e.g.

in ground-to-air communication
