2. OGC ® A Foundation for Today A system integration engineer needs a broad range of skills and is likely to be defined by a breadth of knowledge rather than a depth of knowledge – wikipedia.com Software engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software.software Systems engineering is an interdisciplinary field of engineering, that focuses on the development and organization of complex artificial systemsinterdisciplinary engineeringsystems Engineering is an organized and organizing discipline © 2008 Open Geospatial Consortium, Inc.

3. OGC ® Standards are A Form of Organization Standards capture the essence of engineering Standards simplify your work by codifying the best of what has worked elsewhere Standards-based software is great tool for the integrator 3© 2008 Open Geospatial Consortium, Inc.

4. OGC ® 4 Why standards? Some Quotes “Standardization in the GeoWeb is going to be really important if you want to stimulate innovation,” Vinton Cerf, co-designer of TCP/IP and the “Father of the Internet” “We want to have standards applied to all important interfaces... Being vendor-independent, vendor- neutral helps us protect our equity.” Dawn Meyerriecks, DISA, in an interview with the OpenGroup "People want the government to be transparent, so why shouldn't the technology be?" Jim Willis, director of E-government at the Rhode Island Secretary of State office. © 2008 Open Geospatial Consortium, Inc.

5. OGC ® 5 Standards and Resulting Interoperability Are Important Without Standards and Interoperability, there would be no: –INTERNET or WEB! –MOBILE TELEPHONE TECHNOLOGY! –TRANSPORTATION SYSTEMS! –ELECTRIC POWER DISTRIBUTION! These industries offer huge benefits and enjoy widespread acceptance as a result of using standards that enable interoperability – Should Geospatial be any different? © 2008 Open Geospatial Consortium, Inc. Standards are only as good as the organization that creates, manages and maintains them

6. OGC ® 6 What is the OGC and why use it? The Open Geospatial Consortium, Inc. (OGC) is a not-for- profit international voluntary consensus standards organization leading the development of service interface and encoding standards for geospatial and location based services. 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. Our members have spent 14 years doing the organizing work for you to leverage today. © 2008 Open Geospatial Consortium, Inc.

22. OGC ® 22 What do we mean by interoperability? "capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units“ Source: OGC Abstract Specification Topic 12: Services. Derived from ISO 2382-1. © 2008 Open Geospatial Consortium, Inc.

23. OGC ® 23 Why Interoperability? The OGC helps guide industry to agree on ‘interfaces’ for software. Interoperability agreements abound: –You buy stereo components and plug them in –You buy tires and just have them mounted Nobody saw the value of metadata 10 years ago – –Interoperability is a new idea, but the seeds must be nurtured now –The data and processing you need just in time, on time You care because interoperability will drive your costs down and your productivity up –Eliminate translation and transformation –Reduce the cost of writing custom code © 2008 Open Geospatial Consortium, Inc.

24. OGC ® 24 Interoperability, Standards, and the Future The future vision for the information technology industry is driven by requirements for information sharing, software service re-use, web services architectures, the Internet... Interoperability is fundamental to achieving this future vision. © 2008 Open Geospatial Consortium, Inc.

39. OGC ® Copyright 2006, Open Geospatial Consortium, Inc. (OGC)39 Sensors and Sensor Webs Sensor webs are networks of environmental monitors, traffic monitors, industrial sensors, aerial and satellite- borne imaging devices, webcams, health monitors, and stored sensor data. Classic geospatial data remains the foundation for Decision Support Systems and data from sensors adds currency to that picture Sensors and sensor webs provide: –Real time or near real time observations –Data from simple in situ sensors of single phenomena (temperature or wind speed) to complex earth orbiting satellite imagery sensing many different slices of the electromagnetic spectrum

40. OGC ® Copyright 2006, Open Geospatial Consortium, Inc. (OGC)40 Sensor Web: Why and How? Goal: Enable all types of Web and/or Internet-accessible sensors, instruments, and imaging devices to be accessible and, where applicable, controllable via the Web. Vision: Define and approve the standards foundation for "plug-and-play" Web-based sensor networks. –Sensor location is usually a critical parameter for sensors Cooperate with other standards bodies – IEEE 1451 "smart transducer" family of standards – OASIS Common Alerting Protocol (CAP), Web Services Notification (WS-N) and Asynchronous Service Access Protocol (ASAP) specifications.

OGC ® 43 Summary Industry consensus standards have been around a long time and OGC brings that stability to geospatial processing Standardization has marked the way forward for industry after industry and all that is needed now is for system integrators to realize the benefit to them. © 2008 Open Geospatial Consortium, Inc.
