OGC®

A Foundation for TodayA 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.

• Systems engineering is an interdisciplinary field of engineering, that focuses on the development and organization of complex artificial systems

Engineering is an organized and organizing discipline

Standards are A Form of OrganizationStandards 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

Why standards? Some QuotesWhy 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.

Standards and Resulting Interoperability Are ImportantStandards 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?


Standards are only as good as the organization that creates, manages and maintains them

What is the OGC and why use it?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.

The Growth of OGCThe Growth of OGC

• Over 350 members worldwide – 31 countries & 6 continents– 151 European members - (29 Voting UP 30%, none at top level)– 41 Asia-Pacific members – (8 Voting, none at top level)– 156 North America – (43 Voting, 6 at top level)

• Twenty five (up from 18 last year) approved, publicly available Implementation Specifications

• Broad participation with other industry and international standards organizations

• 30+ candidate Implementation Specifications in work

• OGC Reference Model defines interoperable geo architecture

• Rapidly growing list of vendor implementations

OGC-based Policy PositionsOGC-based Policy Positions

• UK Ordnance Survey uses GML encoding to distribute its MasterMap product

• Canada Geospatial Data Infrastructure (CGDI) Implements OGC Web Service Specifications

• CIA and DHS have adopted OGC as part of their Geospatial Enterprise Architectures.

• Australian SDI recognizes OGC standards, numerous enterprise implementations across the nation

• European Union INSPIRE technical architecture built around OGC specifications

• Open Location Services (mobile wireless) being built into consumer offerings from major location services vendors

• Easier integration leading to lower costs

• Easier sharing with other departments, businesses, countries leading to faster communication

• Easier data sharing leading to more available

• Ability to spend less engineering money reinventing the wheel and spend more of it actually working an unsolved problem– I know there is a comfort zone of doing what one already knows, but

there is also great satisfaction in blazing new trails

SummarySummary

• 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.
