The OGC Mission
To serve as a global forum for and lead the
development, promotion and harmonization of open and freely available geospatial standards.

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.

OGC Interoperability
OGC members identify interoperability problems: ● „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.“
OGC Open Geospatial Consortium, 2011 – Making Location Count...
What is Interoperability?
"The 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.

What is an OGC Standard?
• A document, established by consensus, approved by the OGC membership
• 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 Open Standards– Freely and publicly available– No license fees– Vendor neutral
OGC Open Geospatial Consortium, 2011 – Making Location Count...
Why Open Standards?
● Rapidly mobilize new capabilities – plug and play
• Lower systems costs
• Encourage market competition
– Choose based on functionality desired
– Avoid “lock in” to a proprietary architecture
• Decisions to share information and services become policy decisions
„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

EU Digital Agenda
“Interoperability boosts competition, we need more of that. For devices or applications to be interoperable - to work together - all concerned parties must agree to a common way of doing things.
Formal standards are one way to get there.
More transparency in formal standard-setting can lead to more efficient outcomes. Public and private procurers of technology should be smart and build their systems as much as possible on standards that everybody can use and implement without constraints: this is good for the bottom-line because it promotes competition between suppliers and prevents vendor lock-in.“

OGC-based Policy Positions
• European Union INSPIRE Directive emphasizing ISO and OGC standards for improved interoperability.
• UK Ordnance Survey distributes its MasterMap product using OGC standards.
• Dutch Policy on Open Standards and Open Source Software (http://geostandards.geonovum.nl/index.php/1.1.3_What_are_open_standards%3F)
• Canadian, Australian, US, Indian and other national Spatial Data programs recommend OGC standards as best practice for interoperability.

Interfaces in the standards setting process
Many OGC members are involved in the INSPIRE process and vice-versa:→ INSPIRE Legally Mandated Organisations (LMO): IGN (F), BKG (D), DEFRA (UK), Finnish Meteorological Institute, Geonovum (NL), etc.
→ INSPIRE Spatial Data Interest Communities (SDIC): OGC France Forum (F), SDI of Catalonia (ES), OGC Hydrology DWG
→ Drafting Teams, Thematic Working Groups, thematic overlapping (e.g. Hydrology, Meteorolgy and the TWG on Atmospheric Conditions and Meteorological Geographical features etc.)
→ IOC Task Force
And of course the collaboration with the Joint Research Center (JRC) and other EU agencies.
Some OGC Interoperability Program Initiatives reflect INSPIRE topics.

INSPIRE and OGC Standards
→ Market Report on OGC Standards in INPSIRE provide examples activities underway around INSPIRE based on international standards, highlight overlap between OGC and ISO standards (e.g. ISO 19115)
→ INSPIRE Annex II & II heavily rely on coverages (ortho images, elevation data, classifications, metocean data etc.
→ OGC encoding standards in INSPIRE for spatial data interoperability OGC GML default encoding
→ Quotes:
→ “OGC WMS/SLD and OGC SE Symbology Encoding are the normative references in the view service technical guidance”, C. Portele)
→ “Well established communication & collaboration between OGC & INSPIRE” P. Baumann)

EU funded projects (can) find out how to....
• … rapidly mobilize new capabilities – plug and play
• … lower systems costs
• … encourage market competition
• … help defining European requirements and
• … bring them into international processes
OGC Open Geospatial Consortium, 2011 – Making Location Count...
Examples
• BRISEIDE develops spatial analysis (OGC) WPSs and integrates them within existing open source frameworks. (…)
• Newly developed or protypical OGC Web Services already made available by relevant INSPIRE-related EU projects and exposing standard services such as WMS, WCS and WFS (...)
• Will address the relevant themes on a consensus building approach● http://www.briseide.eu
• Services freely accessible through the web will be developed, assessing the different existing solutions but also guaranteeing the use of standard services (Web Map Services – WMS, Web Processing Services – WPS, Web Features Services – WFS).

Examples – Humboldthttp://www.esdi-humboldt.eu
• “Conformity with standards and major European initiatives.“
• “The Humboldt Tools and Services are built on current state of the art and standards, designed to provide solutions to all types of users, data custodians as well as private end-users.“
• (Many) Humboldt Project Partner are OGC members: Fraunhofer Institute for Computer Graphics, Help Service Remote Sensing, Logica, French National Geographic Institute, ETHZ, Delft University of Technology, Technische Universität München, Natural Environment Research Council, Collecte Localisation Satellites, Högskolan i Gävle
• Most of the Humboldt scenarios match with OGC working groups and Interoperability Program topics

Collaboration and Cooperation
● OGC formal Liaison with CEN/TC 287 for standards coordination● OGC has a Class A Liaison with Technical Committee 211
OGC Open Geospatial Consortium, 2011 – Making Location Count...
The CEN/TC 287 workshop on best practice for National Spatial Data Infrastructures (NSDIs) convened in Saint-Denis, Paris, France on 1 March 2010. This provided an excellent venue and opportunity for organizational representatives of
CEN/TC 287, ISO/TC 211 and OGC to discuss ways in which coordination between these standards bodies can be improved to better address European and international standards requirements.
Discussions also included representatives from participating user communities, and led to general agreement for closer, more formal cooperation between OGC and CEN/TC 287, as well as agreement to consider continued
improvements in OGC and ISO/TC 211 coordination. Emphasis was also placed on the testing of standards for viability, fulfillment of purpose, ease of implementation and improvements in interoperability. The mantra "test early, test often" was reflective of this need.
These three organizations will be cooperatively exploring the adoption of a common Change Request / Requirements registry, and will be examining ways in which adopted standards schema can be managed more effectively and efficiently across these organizations. The requirements process is also an effort to
make the standards process more transparent and more responsive to
community needs. All requirements and change requests will be gathered in an open forum visible to the public. All parties agreed that continued exploration of process improvements would be valuable to the community, with
particular focus on improved coordination, reduction in duplication of effort, and streamlining of standards coordination processes.

Some closing thoughts
● Contribute and work together – participate in the international standardisation process
● Share your experiences especially from an European perspective (EU funded projects).
● Help leveraging European requirements to an international level
“What we are doing is facilitating a common picture of reality for different organizations which have different
views of the reality, the disaster, the catastrophe, that they all have to deal with collectively.”
