1 The Importance of OGC Standards for GIS Operations – WMS, WFS and Beyond Presentation to URISA Ontario Chapter Be Spatial 2009 By Jury Konga and Chris North May 5 th,2009.

2 The Importance of OGC Standards for GIS Operations February 12, Ontario 2 Acknowledgements Sam Bacharach, Executive Director, Outreach and Community Adoption Open Geospatial Consortium (OGC) Fellow workshop speakers for their thoughts OGC - Much of the early material was provided by OGC and is copyrighted NOTE: The views expressed are those of the presenters and do not necessarily reflect the opinions of their employers.

3 The Importance of OGC Standards for GIS Operations February 12, Ontario 3 Overview Why are Open Standards Important? Open Geospatial Consortium – the short story OGC and the “Web Standards World” Family of Web Services and OGC Scope Where to go for OGC Standards Spatial Data Infrastructures GIS operations and interoperability among systems.

4 The Importance of OGC Standards for GIS Operations February 12, Ontario 4 Why are Open Standards Important? Without Standards that lead to Interoperability, there would be no: INTERNET or WEB! CELLULAR TECHNOLOGY! TRANSPORTATION SYSTEMS! ELECTRIC POWER DISTRIBUTION! These industries offer huge benefits and enjoy widespread benefits as a result of using standards that enable interoperability – Can geospatial be any different?

5 The Importance of OGC Standards for GIS Operations February 12, Ontario 5 Why should we be interested in Open Geospatial Standards? Data exchange and distribution is growing Public sector data partnerships and data exchange requirements are going significantly Need for automating our processes to reduce drain on personnel resources The Mashup World Increasing combining of data from many sources to provide new perspectives Data originates from many organizations with differing systems/platforms and data standards Common need – interoperability … enter OGC

6 The Importance of OGC Standards for GIS Operations February 12, Ontario 6 OGC - the short story The Open Geospatial Consortium, Inc. (OGC) is a not-for-profit international voluntary consensus standards organization leading the development of standards for geospatial and location based services. OGC evolved out of a prior group, "Open GRASS Foundation“, which focused on the public domain software GRASS (Geographic Resource and Analysis Support System) from the early 1980s In the early 1990s, government’s widespread use of commercial GIS software posed challenges in collaboration and data sharing: the issue of data sharing had become important Actual “technical interoperability” – real-time communication of data and instructions between two different systems – was an idea only a few had explored. OGC was founded with eight charter members (government, private sector and academia) at the time of its first Board of Directors meeting on September 25, 1994.

7 The Importance of OGC Standards for GIS Operations February 12, Ontario 7 OGC - the short story The OGC facilitates a consensus process in which government, private industry, and academia collaborate to create open and extensible software application programming interfaces for geospatial and other mainstream information technologies. OGC has continued to make progress, from the Specification Program's first approved implementation specification in 1997 and the first Interoperability Program testbed (Web Mapping Testbed) in 1999 to today's broad array of specifications and initiatives. In 2004, the original name Open GIS Consortium, was replaced by Open Geospatial Consortium to reflect a wider scope: “Location Based Services, Imagery Exploitation, Cartography and Mapping, Transportation and GIS” OGC members have spent over 18 years doing the organizing work for you to leverage today.

8 The Importance of OGC Standards for GIS Operations February 12, Ontario 8 Where does OGC fit in the ‘standards world’? IETF / W3C Infrastructure: WSDL, UDDI, SOAP, XML ISO – CEN ANSI / CGSB Domains: Object / Abstract Models, Content, Vocabulary OGC Software Interfaces: Instantiate Domain and Dejure into Infrastructure DeFacto De Jure DomainInfrastructure User Content Via OGC Interfaces IT Infrastructure © 2008 Open Geospatial Consortium, Inc.

9 The Importance of OGC Standards for GIS Operations February 12, Ontario 9 OGC Alliance Partnerships A Critical Resource for Advancing Standards World Wide Web Consortium (W3C) Internet Engineering Task Force (IETF) COMCARE Digital Geospatial Information Working Group (DGIWG) Global Spatial Data Infrastructure Association (GSDI) Group on Earth Observations International Organization for Standards (ISO) Technical Committee 211 OASIS (ACXML) Object Management Group (OMG) Open Mobile Alliance (OMA) Open Grid Forum (OGF) Simulation Interoperability Standards Organization International Alliance for Interoperability (IAI) IEEE Geoscience & Remote Sensing Society IEEE Technical Committee 9 (Sensor Web) Taxonomic Data Working Group (TDWG)

10 The Importance of OGC Standards for GIS Operations February 12, Ontario 10 The Results of OGC Work Easier integration leading to lower costs Easier sharing with other departments, businesses, countries leading to faster communication Easier data sharing leading to more data available Ability to spend less of your money reinventing the wheel Ability to spend more of your money doing your job What’s the scope and future of OGC work?

11 The Importance of OGC Standards for GIS Operations February 12, Ontario 11 The Family of Web Services W3C origin of “web services” – SOAP (Simple Object Access Protocol),UDDI (Universal Description, Discovery and Integration), WSDL (Web Services Description Language) Family of web services expanding dramatically Example – Ontario University masters research project: Interoperability in Sensor Networks Component is Mapping Web Service Also Sensor Web Service Source:

12 The Importance of OGC Standards for GIS Operations February 12, Ontario 12 Example - Sensor Web Enablement (SWE) (think about live resources)

13 The Importance of OGC Standards for GIS Operations February 12, Ontario 13 The spatial web is enabled by OGC standards Web Map Service (OGC & ISO) Style Layer Descriptor (OGC) Feature Model & GML (OGC & ISO) Web Feature Service (OGC) Web Coverage Service (OGC) Web Map Context (OGC) Catalogue (OGC ) Metadata (ISO & OGC) Web Processing Service (OGC) Others… Just as is the dial tone of the World Wide Web, and html / xml are the standard encodings, the spatial web is enabled by OGC standards, such as…
