Open Geospatial Consortium, Inc™
(OGC) – The Organisation
• “The Open Geospatial Consortium, Inc (OGC) is an
international industry consortium of 279 companies,
government agencies and universities participating in a
consensus process to develop publicly available interface
specifications.”
• Vision
– “A world in which everyone benefits from geographic
information and services made available across any network,
application, or platform.”
• Mission
– “To lead the global development, promotion and harmonization
of open standards and architectures that enable the
integration of geospatial data and services into user
applications and advance the formation of related market
opportunities.”

OGC™ - The Process
http://www.opengeospatial.org/about/?page=process
OGC™ - The Abstract Specification
• “The OGC Technical Committee (TC) has
developed an architecture in support of its vision
of geospatial technology and data interoperability
called the OGC Abstract Specification. The
Abstract Specification provides the conceptual
foundation for most OGC specification
development activities.”
• 17 topics
– Overview, Feature Geometry, Spatial Referencing by Coordinates, Features, Metadata, Catalog Services, etc.
http://www.opengeospatial.org/specs/?page=abstract
OGC™ - The Standards (I)
• Database storage and access
– Simple Features (SF) for SQL
– SF for OLE/COM
• OLE DB Provider part
http://www.opengeospatial.org/specs/
OGC™ - The Standards (II)
• Low-level API
– SF for OLE/COM and Corba
– Co-ordinate Transformations Services
(CTS) for OLE/COM
– Grid Coverages (GC) for OLE/COM
http://www.opengeospatial.org/specs/
OGC™ - The Standards (III)
• Web Services
– Web Map Service (WMS)
– Web Feature Service (WFS)
– Web Coverage Service (WCS)
– Catalog Services for the Web (CS-W)
http://www.opengeospatial.org/specs/
OGC™ - The Standards (IV)
• Geography Markup Language (GML)
• Open Location Services (OpenLS)
http://www.opengeospatial.org/specs/
OGC™ - Not The Standards
• Discussion Papers (48)
– “Discussion papers present technology issues being considered
in the Working Groups of the Open Geospatial Consortium
Technical Committee. Their purpose is to create discussion in
the geospatial information industry on a specific topic. These
papers do not represent the official position of the Open
Geospatial Consortium nor of the OGC Technical Committee.”
• Recommendation Papers (9)
– “OGC Recommendation Papers are developed via OGC's
Technology Development Process and reflect an official
position of OGC. Recommendation papers are not Adopted
Specifications, but set direction for specification development.
If a Recommendation Paper is focused on engineering
specifications, then one may assume that the content is still
under rapid change and that the reader should recognize the
volatile nature of the specification when building
implementations.”
OGC™ - The Compliance Tests
• SF for SQL
– SQL-based test suite
• SF, CTS and GC for OLE/COM
– Microsoft Visual Basic test suite
• WMS and WFS
– On-line test suite
– GML 2.1.x validator
– WCS soon
http://www.opengeospatial.org/resources/?page=testing
OGC™ - ISO/TC 204 and TC 211
• TC 204 – Intelligent Transportation Systems
– OGC collaborates via staff and members
• TC 211 – Geospatial
– OGC has Class A Liaison
– OGC and TC 211 share documents, generate New Work
Item Proposals (NWIPs) and have joint editing teams
– Several ISO standards are part of the OGC Abstract
Specification
– Several OGC standards are ISO standards
• More are pending
