Open Geospatial Consortium
The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization that develops and maintains international standards for geospatial content and location-based services, sensor web, Internet of Things, GIS data processing and data sharing. The OGC was incorporated as a not for profit in 1994. At that time, the official name was the OpenGIS Consortium. It is a U.S.-registered 501c(6) non-profit with offices in Belgium and the U.K. Commercial, government, nonprofit, universities, and research organizations from around the world participate in a consensus process encouraging development, maintenance, and implementation of open standards. HistoryA predecessor organization, OGF, the Open GRASS Foundation, started in 1992.[2] From 1994 to 2004 the organization used the name OpenGIS Consortium. The OGC website gives a detailed history of the OGC.[3] StandardsMost of the OGC Standards depend on a generalized architecture captured in a set of documents collectively called the Abstract Specification. The topic volumes in the Abstract Specification describe conceptual and logical models for representing geographic features, coverage data, sensors and other geographic phenomena. Atop the Abstract Specification members have developed and continue to develop a growing number of standards to serve specific needs for interoperable location and geospatial technology, including GIS.
 The OGC standards baseline comprises more than 80 Standards,[4] including:
Simple Features Access, first approved in 1999, was the first full OGC Standard. Shortly after, a series of standards based on the HTTP web services paradigm for message-based interactions in web-based systems were developed and approved. These are known as the OGC Web Service Standards. These include the Web Map Service Interface Standard and the OGC Web Feature Service Interface Standard. More recently, considerable progress has been made in defining and approving a suite of Web API Standards, such as OGC SensorThings API and the OGC API - Features Standard. Organization structureStandards and Compliance programIn the OGC Standards Program the Technical Committee and Planning Committee[11] work in a formal consensus process to arrive at approved (or "adopted") OGC standards.[12] Learn about the standards that have been approved so far, and see the lists of products[13] that implement these standards. The OGC Compliance Program provides the resources, procedures, and policies for improving software implementations' compliance with OGC standards. The Compliance Program provides an online free testing facility,[14] a process[15] for certification and branding of compliant products, and community coordination.[16] The Compliance Program also runs code sprints, which are short term events for increasing interoperability among vendors' products. Collaborative Solutions and Innovation Program (COSI)The Collaborative Solutions and Innovation Program (COSI) is OGC’s Research and Development arm, driving interoperability though initiatives like testbeds, pilot projects and experiments. COSI unites expertise and funding to tackle urgent security, environmental and societal challenges such as flood and wildfire resilience, the land- sea interface and digital twins. Sponsored by some of the world’s premier governmental agencies, COSI’s collaborative approach accelerates technological development while assessing the maturity of solutions, increasing their acceptance in the market. Over the last two decades, OGC has completed more than 140 initiatives and redistributed millions of dollars to member organizations.[17] Community ResourcesThe OGC and its members offer resources to help technology developers and users take advantage of the OGC's open standards. Technical documents, training materials, test suites, reference implementations and other interoperability resources developed in OGC Interoperability Initiatives are available on our resources page.[18] In addition, the OGC and its members support publications, workshops, seminars and conferences[19] to help technology developers, integrators and procurement managers introduce OGC capabilities into their architectures. MembershipThe OGC offers membership options for industry, government, academic, and not-for-profit organizations. Individuals may also join the OGC.[20] Relationships with Other Standards OrganizationsThe OGC has a close relationship with ISO/TC 211 (Geographic Information/Geomatics). Volumes from the ISO 19100 series under development by this committee progressively replace the OGC abstract specification. Further, the OGC standards Web Map Service, GML, Web Feature Service, Observations and Measurements, and Simple Features Access have become ISO standards.[21] The OGC works with more than 20 international standards-bodies including W3C, OASIS, WfMC, and the IETF.[22] See also
