Formerly called
Open GIS Consortium

TheOpen Geospatial Consortium(OGC), an international voluntary consensusstandards organizationforgeospatialcontent andlocation-based services,sensor webandInternet of Things,GISdata processinganddata sharing.It originated in 1994 and involves more than 500 commercial, governmental, nonprofit and research organizations in a consensus process encouraging development and implementation of open standards.

History

[edit]

A predecessor organization, OGF, the OpenGRASSFoundation, started in 1992.[2]

From 1994 to 2004 the organization also used the nameOpen GIS Consortium.

The OGC website gives a detailed history of the OGC.[3]

Standards

[edit]

Most of the OGC standards depend on a generalized architecture captured in a set of documents collectively called theAbstract Specification,which describes a basic data model for representinggeographic features.Atop the Abstract Specification members have developed and continue to develop a growing number of specifications, orstandardsto serve specific needs forinteroperablelocation and geospatial technology, including GIS.

Relationship between clients/servers and OGC protocols

The OGC standards baseline comprises more than 30 standards,[4]including:

  • 3D Tiles – Designed for streaming and rendering massive 3D geospatial content such as Photogrammetry, 3D Buildings, BIM/CAD, Instanced Features, and Point Clouds.
  • CSW– Catalog Service for the Web: access to catalog information
  • GML– Geography Markup Language:XML-format for geographical information
  • GeoPackage– An open, standards-based, platform-independent, portable, self-describing, compact format for transferring geospatial information[5]
  • GeoPose- An encoding standard describing the position and orientation/rotation of a 3d object (real or digital) in relation to the real world.[6]
  • GeoSPARQL– Geographic SPARQL Protocol and RDF Query Language:[7]representation and querying of geospatial data for theSemantic Web
  • GeoXACML– Geospatial eXtensible Access Control Markup Language
  • KML–KeyholeMarkup Language:XML-based language schema for expressing geographic annotation and visualization on existing (or future) Web-based, two-dimensional maps and three-dimensional Earth browsers
  • Observations and Measurements
  • OGC Reference Model– a complete set ofreference models
  • OLS– Open Location Service (OpenLS)[8]
  • OGC Web Services Context Documentdefines the application state of an OGC Integrated Client
  • OWS– OGC Web Service Common
  • SOS– Sensor Observation Service[9]
  • SPS – Sensor Planning Service[10]
  • SensorML– Sensor Model Language
  • SensorThings API[11]- an open and unified framework to interconnect IoT devices, data, and applications over the Web. Currently a candidate standard waiting for votes.
  • SFS– Simple Features – SQL
  • SLD- Styled Layer Descriptor
  • SRID,an identification for spatial coordinate systems
  • WaterML– Information model for the representation of hydrological observation data
  • WCS– Web Coverage Service: provides access, subsetting, and processing oncoverage objects
  • WCPS– Web Coverage Processing Service: provides a raster query language for ad-hoc processing and filtering on rastercoverages
  • WFS– Web Feature Service: for retrieving or altering feature descriptions
  • WMS– Web Map Service: provides map images
  • WMTS– Web Map Tile Service: provides map image tiles
  • WPS– Web Processing Service: remote processing service
  • WTS– Web Terrain Service (WTS)

The design of standards were originally built on theHTTPweb servicesparadigmfor message-based interactions in web-based systems, but meanwhile has been extended with a common approach forSOAPprotocol andWSDLbindings. Considerable progress has been made in definingRepresentational State Transfer(REST) web services, e.g., OGCSensorThings API.

Organization structure

[edit]

The OGC has several operational units:

Standards program (SP)

[edit]

In the OGC Standards Program the Technical Committee and Planning Committee[12]work in a formal consensus process to arrive at approved (or "adopted" ) OGC standards.[13]Learn about the standards that have been approved so far, and see the lists of products[14]that implement these standards.

Compliance Program (CP)

[edit]

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,[15]a process[16]for certification and branding of compliant products, and community coordination.[17] The Compliance Program also runs plugfests, which are short term events for increasing interoperability among vendors' products.

Community and Outreach Program (COP)

[edit]

The 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.

Membership

[edit]

The OGC offers membership options for industry, government, academic, research and not-for-profit organizations.[20]

Collaboration

[edit]

The OGC has a close relationship withISO/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 includingW3C,OASIS,WfMC,and theIETF.[22]
