OGC Requests

Please note: This Request closed on 13 December 2013. 

The Open Geospatial Consortium (OGC®) is seeking comments on the candidate standard, "OGC® OpenSearch Geo and Time Extensions". This document extends the implementation of the popular OpenSearch technologies so that users can take advantage of the geospatial search capabilities enabled by OGC standards. 

Different types of content require different types of search engines. OpenSearch (http://www.opensearch.org) provides a standard way of describing search engine capabilities so that they can be leveraged by search client applications like modern Web browsers. The OGC® OpenSearch Geo and Time Extensions candidate standard provides a very simple way to configure OpenSearch for spatial and temporal queries over distributed repositories of contents having geographic and time properties, and for syndication of these search results in one large index.

Digital resources are becoming more complex and diverse, and this is especially true with respect to sensor data and Web connected sensors. Such data is increasingly becoming discoverable and usable through open interfaces that implement OGC standards (http://www.opengeospatial.org/standards), but most of this data remains undiscoverable via popular search engines. The OGC OpenSearch Geo and Time Extensions candidate standard specifies how to enhance search engines and configure them to access sensor data servers, so that users can query resource URLs through search combinations of time extents, geographic areas or location names, and likely keywords. 

The OGC® OpenSearch Geo and Time Extensions draft standard includes work undertaken within the GENESI-DR (Ground European Network for Earth Science Interoperations - Digital Repositories) project funded by the 7th Framework program of the European (EC Grant Agreement no. 212073) and the follow-up project GENESI-DEC (Ground European Network for Earth Science Interoperations - Digital Earth Community) funded by the same program (Contract nº RI-261623). The document was further supported by the ESA HMA (Heterogeneous Missions Accessibility) initiative and related projects.

The community workshop has been re-scheduled to December 17-18 in Washington DC. Contact nalameh [at] opengeospatial [dot] org (Nadine Alameh) if you're interested in participating.


The Open Geospatial Consortium (OGC) has issued a Request for Information (RFI) to engage the aviation community in identifying standards efforts relevant to the provision of aircraft connectivity to the FAA’s System Wide Information Management (SWIM) infrastructure.

RFI Information:

  • Responses are due by 5 pm EST on 22 October 2013. 
  • A public Q&A webinar was held 1 October 2013 to provide the community with more information on the context and objectives behind this RFI. Documentation below. 

The FAA’s Aircraft Access to SWIM (AAtS) initiative is in a preliminary stage of requirements development and standards identification. Its goal is to establish a common operating environment between the flight deck, air traffic management and Airline Operational Control/Flight Operational Control (AOC/FOC) for collaborative strategic decision-making. Distribution of the operational information needed to support the safe movement of aircraft during all phases of flight in the National Airspace System (NAS) will increase capacity and efficiency and result in more timely departures and arrivals.  

There are a number of aviation standards in development, concurrently and independently, by a variety of industry groups that are also pursuing the development of requirements and standards to leverage ground-based aviation related information and data networking technology to support aircraft operations. The need to understand the scope, applicability and relationship between these efforts is both critical and timely.

Staff and members of all such industry groups are encouraged to respond to this RFI and to participate and contribute information on:

  • Technologies, standards and general trends relevant to AAtS
  • Practical recommendations on harmonization opportunities and challenges
  • Insights on how to best craft an interim path for the community and to develop a technical architecture that is forward thinking and can accommodate this emerging and evolving environment.
  • Global harmonization considerations 

Responses provided will guide the discussion at a community workshop, scheduled for 17-18 December 2013 in Washington DC, and will be considered in the development of a report that will form the basis for harmonization guidance and recommendations. 



Community Workshop: 

  • The community workshop, originally scheduled for Nov 5-6, has been rescheduled to Dec 17-18, 2013. Email nalameh [at] opengeospatial [dot] org if you're interested in attending. 
  • All organization representatives interested in participating in the workshop are strongly encouraged to submit a concise response to the RFI, in order to help us organize the workshop efficiently and incorporate everybody's interests.

Please send an email to techdesk [at] opengeospatial [dot] org if you have questions or need further information.
