Open GIS Consortium for a changing world. Spatial connectivity OGC Interoperability Program Status Lance McKee Open GIS Consortium, Inc.

Open GIS Consortium for a changing world. Spatial connectivity OGC’s Interoperability Program Goals Accelerate the OpenGIS Specification process. Accelerate acceptance of OpenGIS Specifications. –Pilot programs build critical mass of interoperable sites. –Reference implementations build critical mass of online resources. –Work with with ISO and government officials to make specifying SCOTS a standard procurement practice. Be a public/private partnership that matures and enriches the geospatial market.

Open GIS Consortium for a changing world. Spatial connectivity Interoperability Program Goals, cont’d Overcome current lack of interoperability infrastructure. Shape specs with immediate, hard, commercial feedback. Meet specific user requirements reflected in trends. Help users and providers seize new opportunities. Refine consensus methods for directing technology.

Open GIS Consortium for a changing world. Spatial connectivity Web Mapping Testbed Phase 1 – A Success GetMap - fetches map images from data stores in specified projections (which might be georeferenced images such as JPEG and PNG). GetCapabilities - provides information about what a server can do. GetFeatureInfo - provides a mechanism that allows users to query map displays to get attributes of specific geographic features in a map layer. MapServer Interfaces Version 0.1

Open GIS Consortium for a changing world. Spatial connectivity Goals for Web Mapping Testbed Phase 2 Expand the range of interoperable web mapping services. Create new specifications. Bring more data on-line using WMT protocols. Lay a foundation for Pilot Projects that put local data on-line using WMT protocols. One Web Mapping Pilot, targeting flood control and environmental management in the Upper Susquehanna and Lackawanna River region of Pennsylvania, is already underway.

Open GIS Consortium for a changing world. Spatial connectivity WMT 2 Objectives Finalization of the first three OpenGIS Web Map Server Interface Protocols. Provide interoperability mechanisms for legends and symbols. Add authoring and publishing tools, WMT protocol Tool Kits : "How to" implement protocols on map servers for easy of serving maps on the Web. Enhance GetMap so it serves up simple features. WMT I focused on raster (e.g. GIF) format transfers. WMT 2 will support transporting vector feature data (either in graphical or geographical form in XML-based packaging) to enable smart applications. Integrate Web Mapping with Catalog Services. Give users tools to cope with very large libraries of imagery and spatial information. Make agency servers available on-line via WMT protocols. Extend vector feature data access capability to imagery and raster data (“grid coverages”) to get information at a specific point in the image (e.g., average temperature at a specific location).

Open GIS Consortium for a changing world. Spatial connectivity WMT 2 Organizational Issues The WMT 2 initiative is expected to run from May until November, Initiative is funded through “MIPR’ing” of agencies’ money through NIMA. Work cannot begin until funds are received. It is not too late for new sponsors to join and add their requirements – use cases, scenarios. Reconciling of sponsors’ requirements and testbed scope will happen in the second requirements meeting (date TBD) and in the process of writing the RFQ.

Open GIS Consortium for a changing world. Spatial connectivity Coming Soon: New Interoperability Initiatives Pending: SCOTS JMTK (Standards-based Commercial Off-The-Shelf Joint Mapping ToolKit) Testbed. Multi-phase, April, June, Sponsor is NIMA. SCOTS JMTK will nominate commercial APIs to replace most or all of NIMA's JMTK APIs, so multiple vendors can compete to provide different but interoperable elements of the toolkit. Planned: "Web Mapping Infrastructure," a distributed and rigorously maintained set of reference servers (and supporting databases), reference clients, and reference documents to support Initiatives. Planned: "opengis.net”, extension of Web Mapping Infrastructure, to provide "Reference Implementations," working prototypes robust enough to serve as templates for similar implementations. Opengis.net will provide test tools and a test environment.

Open GIS Consortium for a changing world. Spatial connectivity How to Do More, Sooner, Better: Agencies that need interoperability will get it sooner, and will shape it, if they share in its development. Support FGDC’s NSDI development programs. Participate in OGC’s Gov SIG. Work with other agencies (and industry) to coordinate requirements, share costs.
