The results of this major interoperability testbed, which began in 2015, were demonstrated on 4 June 2015 during the OGC Technical Committee meeting held in Boulder, CO. The results will contribute to development and refinement of international standards that are critical for the communication and integration of geospatial information. Results from this testbed and previous OGC testbeds provide a foundation for the next OGC testbed, Testbed 12, which will begin in September 2015. If you want to learn more about the Testbed 12 Call for Sponsors, please contact Terry Idol, Executive Director, Interoperability Program, (tidol[at]opengeospatial.org).

In December 2014 the White House Office of Science and Technology (OSTP) released a Policy Fact Sheet titled "Harnessing Climate Data to Boost Ecosystem & Water Resilience." The Fact Sheet lists OGC’s commitment to increase open access to climate change information using open standards. Testbed 11, identified in the OSTP document and sponsored by an international group of government agencies, supports national climate-change preparedness by focusing on the spatial information to illustrate potential impacts that would lead to populations being displaced due to coastal inundation.

Nine Testbed 11 sponsors documented interoperability requirements and objectives for this activity. Thirty organizations selected to participate in Testbed 11 then developed solutions based on the sponsors’ use cases, requirements and scenarios described in a Call for Proposals. Participants’ solutions implement existing OGC standards as well as prototypes of possible interface and encoding candidate standards. Some of the prototypes may ultimately become OGC standards, revisions to existing OGC standards, or best practices for using OGC standards.


Testbed 11 Sponsors included:

  • European Organization for the Safety of Air Navigation (EUROCONTROL)
  • Land Information New Zealand (LINZ)
  • National Aeronautics and Space Administration (NASA)
  • National Geospatial-Intelligence Agency (NGA)
  • Program Manager, Information Sharing Environment (PM-ISE)
  • UAE Ministry of Interior Abu Dhabi Police GIS Center for Security (UAE ADP-GIS SC)
  • UK Defense Science and Technology Lab (UK-DSTL)
  • US Geological Survey (USGS)
  • other U.S. Government Sponsors


Testbed participants addressing requirements in the sponsors’ scenario developed interoperability solutions to meet these goals:

  • Advance OGC Architecture with respect to REST and SOAP design patterns for synchronization of geodata across data stores, as well as storage and synchronization of geodata in GeoPackages;
  • Evaluate approaches to JSON and GeoJSON encodings as well as vector data and image streaming in the OGC standards framework;
  • Integrate high-resolution simulation models into geospatial infrastructures using the OGC Web Processing Service;
  • Advance use of Linked Data and semantic enabling of OGC Web Services, with a special focus on Hydrographic Data;
  • Advance use of OGC Catalog Services;
  • Advance use of spatially-enabled Social Media data;
  • Advance use of a common symbology that can be used to share common operational pictures in an international environment;
  • Advance compliance tests for the OGC Web Feature Service and Catalog 3.0 Service interface standards;
  • In Aviation, advance a Digital Notice to Airmen (NOTAM) validation service and enrichment service and advance use of Aviation Feature Schema (AFX). Also develop guidance on using geometrical constraints in the Semantics of Business Vocabulary and Rules (SBVR) (an Object Management Group standard).

Those testbed goals were organized into these four technology threads:

Demonstrated Outcomes

On 4 June, 2015, the OGC demonstrated the results of the eleventh OGC Interoperability Testbed. The demonstration was held during the OGC Technical Committee Meeting in Boulder, Colorado, USA.

Testbed 11 participants documented the results of the Testbed in OGC Engineering Reports and are listed in the following table. The Engineering Reports (ERs) are being finalized for publication as Public Engineering Reports. The table will provide a link to the published ER as they become available.

The demonstrated results have enormous potential for the testbed stakeholders – both technology users and the technology providers – and for the world at large. The return on the shared investment in spatial standards is extraordinary, much like the return on the original shared investments in http and html.

Engineering Reports (by Thread)

The following tables identify the ERs developed during this Testbed 11, organized by Thread. Links will be added to each of the ERs, as they become available, to facilitate locating and downloading the documents on the OGC Public Engineering Reports page.

In addition to these task related ERs, the OGC will publish a high-level summary ER that provides more details about Testbed 11. This summary ER will be available on the OGC Public Engineering Reports page as identified below:

Next Steps

Sponsors have already begun assembling interoperability requirements for Testbed 12, which will begin in the fall. Current prospective sponsors and the OGC invite other organizations to bring their requirements into the discussion.
