What is OGC?What is OGC?
• The Open Geospatial Consortium, Inc.® (OGC) is a international, voluntary consensus standards organization that is leading the development of standards for geospatial and location based services.
• Founded in 1994 as a not-for-profit trade association
• 340+ members to date around the world (majority in North America & Europe)
• Focus is on interoperability of geospatial systems
• OGC is funded and devised to identify where the pain is in the market and to solve it… with rapid, market driven commercial specification development
"The greatest challenge to any thinker is stating the problem in a waythat will allow a solution"
-- Bertrand Russell

SOA applied to Geospatial � SDI (Spatial Data Infrastructure)
• A Spatial Data Infrastructure is the relevant base collection of technologies, interoperable data modeling, policies and institutional arrangements that facilitate the availability and access to spatial data.
• The SDI provides a basis for spatial data discovery, evaluation, and application for users and providers across several domains and within all levels of government, in the commercial sector, the non-profit sector, academia and citizens in general
• A Spatial Data Infrastructure is more than a single data set or database; an SDI hosts geographic data and attributes, it should provide
– sufficient documentation (metadata)
– a means to discover, visualize, and evaluate the da ta (Catalogues and Web Mapping)
– some method to provide access to the geographic dat a(Un-portrayed data)

Spatial Data Infrastructure - Architecture
INSPIRE architectural vision
• The architecture envisioned by INSPIRE deploys interoperable servicesthat will help to produce and publish, find and access, and eventually, use and understand geographic information over the Internet across European Union and Association Countries at local, national, andEuropean levels
• Service Oriented Architecture (SOA) & Web Services – Independent components, based on open transport protocols and XML
based standards for data exchange– Standards provide interoperability (interface semantics, data encoding, etc.)– Accessible through HTTP (universal access) – Service Registry as access point to the system resources
172002 ARCHITECTURE AND STANDARDS WORKING GROUP - INSPIRE Architecture and Standards Position Paper, JRC-Institute for Environment and Sustainability, Ispra (64p)
INSPIRE Principles
• Data should be collected once and maintained at the level where this can be done most effectively
• It must be possible to combine seamlessly spatial information from different sources and share it between many users a nd applications
• It must be possible for information collected at on e level to be sharedbetween all the different levels, e.g. detailed for detailed investigations, general for strategic purposes
• Geographic information needed for good governance a t all levels should be abundant and widely available under conditions that do not restrain its extensive use
• It must be easy to discover which geographic information is available, fits the needs for a particular use and under what condi tions it can be acquired and used
• Geographic data must become easy to understand and interpret because it can be visualized within the appropriate context and selected in a us er friendly way

Conclusion
� Open Architecture
� True Interoperability when Standards-Based (OGC/ISO/OASIS)
� Direct Access to Vector & Imagery Data via Enterprise or Web Services
� J2EE / Enterprise Components
� Comprehensive Standard API
� Scalable, Robust, Secure Software
� Supports High Volumes of Data
+ OGC/ISO roadmap supporting evolution vs market requirements
Benefits of Open Standard-based SOA
Conclusion
� Standard-based SOA allow to develop faster more powerful applications with less costs (interchangeable & reusable)
� With standard-based SOA, Geospatial interoperability delivers more value at lower costs
� Standard-based SOA opens new horizon & challenges
� Standard-based SOA allows to formalize a federating framework to develop interoperable system at organization level but also across organizations
� … and all players take benefit of it !
