OGC Testbed 11
This major interoperability testbed, which began in 2015, is nearing completion with finalization of engineering reports and demo videos. These 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.

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, mentioned 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)
- UAE Ministry of Interior Abu Dhabi Police GIS Center for Security (UAE ADP-GIS SC)
- UK Defense Science and Technology Lab (UK-DSTL)
- US Department of Homeland Security (DHS)
- US Federal Aviation Administration (FAA)
- US Geological Survey (USGS)
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 sort into these four technology threads:
Testbed 11 participants are documenting the results in OGC Engineering Reports that will become available to the public. 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.
Some of the Testbed 11 sponsors have already begun assembling interoperability requirements for Testbed 12, which will begin in the fall. The sponsors and the OGC invite other organizations to bring their requirements into the discussion.
