OGC ® OGC Global Relationships Working with the OGC Interoperability Program can directly engage with global ICAN participants and support networks in multiple continents: –N.America, Europe, Africa, etc. OGC-WMO relationship connects OGC with JCOMM and IOC/IODE –Would like to strengthen this liaison –Strongest OGC-WMO ties so far in meteorology and hydrology OGC has strong membership in Europe and Australia –Europe now accounts for half of OGC member organizations –European INSPIRE program requires OGC standards © 2010 Open Geospatial Consortium, Inc.4

OGC ® Interoperability Program Overview Testbeds: Fast-paced, multi-vendor collaborative efforts to define, design, develop, and test candidate interface and encoding standards. Pilot Projects: Apply and test OGC Standards in real world applications using commercial off-the-shelf (SCOTS) products that implement OGC Standards. Interoperability Experiments: Low-overhead, formally structured initiatives led and executed by OGC members to achieve specific technical objectives. Interoperability Support Services are designed to help organizations with open, standards based architecture. © 2010 Open Geospatial Consortium, Inc.5

OGC ® OGC Web Services Initiative, Phase 7 (OWS-7) Testbed: Aviation Weather Aviation thread: Collaboration funded by the US FAA and Eurocontrol, with strong support from the NextGen Network-Enabled Weather (NNEW) Program, to advance AIXM (Aeronautical Information Exchange Model) and WXXM (Weather Information Exchange Model) specifications. NNEW Program: Tasked with creating an infrastructure that will allow users of the United States' national airspace system — from air traffic controllers to National Weather Service employees — to access a single, nationwide picture of the weather.national airspace systemNational Weather Service 4-D Wx Data Cube Infrastructure: Support dissemination of up-to-the-minute weather information synthesized from tens of thousands of data sources.4-D Wx Data Cube © 2010 Open Geospatial Consortium, Inc.6 NNEW wiki: OWS-7 Aviation:

OGC ® CGDI Pilot 2007: Geosynchronization Purpose: to keep multiple databases synchronized around common entities, without the restrictions of database replication (ie, that all databases must have identical schemas). Well suited for national- regional-local database coordination. Approach: GIS editing clients implement a WFS-T server, enabling other users to request copies of changes made. This was developed in an Interoperability Pilot for Natural Resources Canada / GeoConnections in 2007, called the Canadian Geospatial Data Infrastructure (CGDI) Pilot. –OGC CGDI Summary Report –OGC Loosely Coupled Synchronization of Geographic Databases in the CGDI –OGC CGDI Best Practices Engineering Report In OWS-7, Geo-Synchronization Services (GSS) were further tested, refined, and documented in a public engineering report, OGC r2, © 2010 Open Geospatial Consortium, Inc.11

OGC ® Comparison of Testbeds, Pilots and IE’s OWS-7 Testbed: Sponsored. Sponsors dictated requirements and asked OGC to manage the selection & efforts of participants. Experimental work intended to enhance current standards. CGDI Pilot: A pilot because of performance requirements. Need was to implement and test current adopted OGC standards. Hydro & MetOcean IE’s: Participants have sufficient expertise to self- organize and provide the technical leadership needed to accomplish their goals in a reasonable time. Goals are focused and achievable in 6-month time frame. No sponsorship funding. © 2010 Open Geospatial Consortium, Inc.14

OGC ® ICAN Coastal Web Atlas IE? Decide on goals, objectives, partners –Pick representative CWA use cases to implement, preferably involving international agency coordination and data exchange –Determine data sources and web services needed to carry out –Engage key data producers, researchers, other stakeholders; decide on leadership –To what degree can all stakeholders’ schemas be harmonized? No additional funding required to support OGC involvement –OGC would assign a staff person to “facilitate” and keep an eye on development, to ensure it stays consistent with OGC’s policies –OGC Architecture Board (OAB) would review & approve IE proposal –OGC would maintain the IE’s mail list, and project wiki © 2010 Open Geospatial Consortium, Inc.15

OGC ® ICAN Coastal Web Atlas Pilot? Decide on goals, objectives, partners –Define use cases to implement, preferably involving international agency coordination and data exchange –Determine data sources and web services –Engage key data producers, researchers, other stakeholders; –Decide on leadership –Issue: Can all stakeholders’ schemas be harmonized? OGC engages GIS/IT community and manages project –Sponsor funding required for OGC staff –RFQ/CFP is published widely, soliciting numerous commercial and academic developers to solve stated problems (+ mentor resources!) –Sponsor funding required to cover some aspects of participant work. © 2010 Open Geospatial Consortium, Inc.16
