3. Open GIS Consortium for a changing world. Spatial connectivity © 2000, Open GIS Consortium, Inc. All Rights Reserved OGC: Background and Focus Founded in 1994 as a not-for-profit trade association - 200+ members to date Focus is on interoperability of geospatial systems –OGC believes that knowledge enhancement is significantly improved with interoperability and is critical to the future of spatial and non spatial data access and diffusion –OGC believes that working at the interface between systems and processes is the best way forward 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 –Break barriers and facilitate common interests among all communities regardless of medium that use or will use geospatial data and processes We are interested in specifications that are part of standardized COTS (SCOTS)……We then get out of the way as rapidly as possible.

All Rights Reserved Process drives specs Specs drive products Products drive markets Markets drive needs Needs drive requirements Requirements drive process OGC Manages an industry-wide consensus approach for interoperable geoprocessing: Develops OpenGIS Specifications Implement Interoperability Initiatives (Web Mapping and Fusion Testbeds, Useability Pilots and Insertion Studies for members.) Comprehensive Standards Org coordination We have demonstrated interoperability of geospatial systems at two levels: Component Interoperability (tightly-coupled) Messaging Interoperability (loosely-coupled) OGC - Responsive to Markets and Users

6. Open GIS Consortium for a changing world. Spatial connectivity © 2000, Open GIS Consortium, Inc. All Rights Reserved Application Development Options One option, would build applications with any commercial mapping product. –Open competition, no standards –Tightly- and/or loosely-coupled, available now A second option, would be to build applications using commercial products that implement a commercial standard interface. –Open competition, commercial standards –Tightly- and/or loosely-coupled, partly available now

All Rights Reserved OpenGIS ® : Families of SCOTS Interfaces OGC has developed several specifications –Tightly coupled Simple Features (Vector Data Access) Coverages (Image and Gridded Data Access) Coordinate Transformation Catalog Services (fine-grained) –Loosely coupled Catalog Services (coarse-grained) Web Mapping Server Geography Markup Language (loosely coupled “datagram” specification) is nearing completion More on the way….but it is a work in progress

9. Open GIS Consortium for a changing world. Spatial connectivity © 2000, Open GIS Consortium, Inc. All Rights Reserved Why are we here?

10. Open GIS Consortium for a changing world. Spatial connectivity © 2000, Open GIS Consortium, Inc. All Rights Reserved Why we are here…. We want to support IETF in quickly getting location based services into internet settings (at the communications level?) We also know that more complex positioning services are required, soon –More complex geometry (lines, polygons, grids,...) –Addressment of time and life-span of changing information –Different kinds of referencing Multiple coordinate-based referencing Feature based referencing Services that can be built to convert between the two –Want to know where you are to find the right data - where data are positioned –Network wants to know where you are to optimize performance by finding the most efficient provider for the services desired

11. Open GIS Consortium for a changing world. Spatial connectivity © 2000, Open GIS Consortium, Inc. All Rights Reserved Why we are here…. All the above require understanding scalability - which IETF understands –Devolving responsibility for creation and management of services –Local caching and escalating out to rest of framework –Network redundancy OGC understands the nature of spatial content, geoprocessing resources like spatial referencing and its management and use –The scope of geospatial information as addressed inside the Open GIS Consortium is far broader than that needed by industrial forums such as W3C, WAP Forum or IETF. –Open GIS is concerned with modernizing collection and production processes, update, persistent IDs, data and service registries and expanding the modes by which customers, citizens or users may access data and with services for presentation, fusion, analytical modeling, semantics and quality to provide useable information and we gather authentic market consensus as we go.

14. Open GIS Consortium for a changing world. Spatial connectivity © 2000, Open GIS Consortium, Inc. All Rights Reserved Possible Next Steps OGC offers to coordinate with IETF WG if one is formed WG and OGC ought to find the right way to work together- to create a robust scalable and efficient model for deploying location based services OGC is introducing interface technologies into the marketplace now, and would welcome the opportunity to jointly build, test and gather consensus on mutually agreed protocols. –GetLocation - given a place name or address, return a geographic location –GetLocationName - given a geographic location, return a place name –GetAddress - given a geographic location, return an address –TransformLocation - transform a location (or set of locations or the coordinates of a geometry) in one spatial reference system to another spatial reference system
