A few words about OGC
OGC Programs and Processes
Development of an OGC Standard
Communities and Participation

3. Before we start...
Q: What is the OGC's position on "Open Data"? - http://www.opengeospatial.org/ogc/faq#11
The OGC embraces open data as well as other models for data
distribution and access. The OGC standards framework must support a
broad range of policy positions on the access to and distribution of
geospatial data, and we are supportive of all models for open access,
licensed data, secure distribution, etc. Policies on access and distribution
of geospatial and other forms of data are constantly in flux. Data sets
restricted for distribution by security and/or pricing / licensing, may be
opened up for free access at another time. Changing market forces and
organizational policies determine the rules for data access and distribution.
Open standards, including those of the OGC, support the full range of
business models, and a common open standards framework is vital to
the overall geospatial data marketplace.

5. Standards and Interoperability
Availability of geo data is crucial for the administration,
businesses and citizens alike.
But how to share data?
Key factor for accessibility is standardisation. It is the
definition of common interfaces to enable
interoperability.
© 2012 Open Geospatial Consortium
6. Interoperability Issues
●
„We can't share maps on the Web.“
●
„We can't deliver data to different
systems easily.“
●
„We don't have a common language
to speak about our geospatial data
or our services.“
●
„We can't find and pull together data
from our automated sensors.“

7. So what does OGC do?
The Vision
Achieve the full societal, economic and scientific
benefits of integrating location resources into
commercial, institutional and organisational
processes worldwide.
The Mission
To serve as a global forum for
and lead the development, promotion and harmonization of
open and freely available geospatial standards.

13. Improving Knowledge Sharing and Transfer
We are addressing critical issues, that need
cooperation:
●
Growth in urban centers and coastal areas
●
Climate Change, Environmental
Monitoring
●
Water Resource
availability and quality
●
Emergency planning,
preparedness & response
●
Aviation Safety

14. Standards Development is not easy!
→ Requires understanding of differences
→ Requires cooperation on a global basis
→ Requires consensus by many organizations
→ Requires give and take
→ Requires certified, repeatable process

16. What is an OGC Standard?
• A document, established by consensus, approved by the
OGC membership (balance of interest, all members have an equal vote)
• Provides, rules, guidelines or characteristics
• Implementable in software
• Open standards does not mean open source software (Free
Software). OGC/OSGeo Paper on Open Source Software and Open
Standards: http://wiki.osgeo.org/wiki/Open_Source_and_Open_Standards
• OGC standards are „People want the government
Open Standards to be transparent, so why
– Freely and publicly available shouldn't the technology be?”
– No license fees Jim Willis, Director of e-Government at
– Vendor neutral theRhode Island Secretary of State
Office

17. Why Open Standards?
●
Prevents a single, self-interested party from
controlling a standard
„What OGC brings to
• Lower systems and life the table is…everyone
has confidence we
cycle costs won’t take advantage of
the format or change it
• Encourage market competition in a way that will harm
– Choose based on functionality anyone”
desired Michael Weiss-Malik,
– Avoid “lock in” to a proprietary Google KML product
architecture manager
• Stimulates innovation beyond the standard by
companies that seek to differentiate themselves.

parachutes:
they work best
when they're open.

they strike harder when closed.” — L.E. Modesitt, Jr., American Author (1943 -- )

20. How does OGC work?
http://www.opengeospatial.org/projects
• Consensus process – that is reflecting a
common understanding of requirements
and a membership driven process.
• Formalised standards development
process – based on commonly agreed,
structured and well defined policies and
processes (→ Standards Program
http://www.opengeospatial.org/ogc/programs/spec).

28. How is a standard developed?
→ Submitted by a TC Voting Member with a minimum of two
other OGC Member organizations supporting the
submission.
→ An email to TC Chair (Carl Reed) stating the intent to
submit.
→ The document package (cover letter, document in OGC
document template format etc) are sent to Carl Reed and
posted to pending documents.
→ At this point, the process may vary depending on which
path through the approval process the submission team
wishes to use.

29. Major OGC Standards

Some examples Web Feature
Server
Web Coverage
Server
• Web Map Servers (WMS)
• Web Feature Servers (WFS)
• Web Coverage Servers (WCS) Web Map
Server
With OGC web services, a user can dynamically
access that data, directly from the authoritative data
source, using a variety of tools.
As well as the: OGC
• KML (formerly Keyhole Markup Language)
• Web Map Context (WMC)
• Geography Markup Language (GML)
Just as http:// is the dial tone of the World Wide Web,
and html / xml are the standard encodings, the
geospatial web is enabled by OGC standards:

34. IP - Emphasis on Testing and Validation
Testbeds, Pilots and Experiments Over 50 initiatives
Participants work with sponsors to define and/or refine have been
standards to solve a given interoperability problem. successfully
completed since 1999.
–
Joint actions by technology providers and
users Most OGC standards
are advanced through
–
Driven by user community scenarios
this process.
–
Produce:
→ Tested and validated draft standards
→ Industry technology implementations
→ Architectural recommendations
→ Live demonstrations to validate utility of
standards in user context
OGC staff manages the entire
process with policies and procedures
proven to produce results.

35. Understanding OGC standards – the ORM*
OGC Reference Model www.opengeospatial.org/standards/orm
• What is the purpose of the ORM?
– Overview of OGC Standards Baseline
– Insight into the current state of the work of the OGC
– Basis for coordination and understanding of the OGC documents
– Resource for defining architectures for specific applications
• In Spanish

43. How is an OGC standard developed?
http://www.opengeospatial.org/ogc/process
Results achieved in the DWG/SWG may be:
●
A Discussion Paper or a Candidate Standard document is being developed
●
It will be reviewed by the OGC Architecture Board (OAB) and the Technical
Committee (TC).
→ Once an OGC document is published (by vote of the SWG),
everyone who is interested can comment on it within a given
period of time (usually 30d ays):
●
Requests to the document need to be answered by the relevant SWG
●
Changes and comments need to be included (SWG works the comments)
●
SWG votes to release to the TC for an adoption vote, vote happens
→ New approved standard published

51. Closing thoughts...
→ Contribute, cooperate – and avoid „consuming
attitude“
→ Don't re-invent the wheel: benefit from other's
experiences – share your own!
„The conventional view serves to protect us from the painful job
of thinking“ (John Kenneth Galbraith, economist)

53. Some last thoughts...
“Interoperability seems to be about the
integration of information. What it’s really
about is the coordination of organizational
behavior.”

54. GovFuture - new Membership Level for Local
and Subnational Government
new membership option for local and state/provincial government
agencies
worldwide and for a very small fee (200US$/500US$)
(new membership structure for different regions in the world coming soon)
reflects OGC's increased emphasis on knowledge transfer
→ learn about new developments in geospatial technology
→ benefit from those developments
→ understand and address legal and policy issues
→ liaise with other levels of government
