5 Open Standards for Geospatial Interoperability Open Geospatial Consortium (OGC) –Global, not-for-profit, international voluntary consensus standards organization, >300 industry, government, research and university member organizations ISO TC 211 – Geographic Information –International, voluntary consensus standards body, members are nations, liaison with numerous professional organizations OASIS – Organization for the Advancement of Structured Information Standards –Not-for-profit consortium that drives the development, convergence, and adoption of open standards for the global information society

6 Compatible SDI Standards Suite, “SDI 1.0” OGC “SDI Standards Suite Version 1.0”- compatible suite of implemented geospatial standards and specifications Criteria for inclusion –Open consensus standard –Evidence of implementation –Dependencies –Stability and conformance SDI 1.0 facilitates description and acquisition of compatible technology to construct SDIs worldwide –To be presented at GSDI-9 in Chile

7 “SDI Standards Suite Version 1.0” - DRAFT

8 Open Web Services Standards meet GEOSS Architecture Requirements Defined on Internet standards: URLs, HTTP, XML Simple: message-oriented, stateless, common elements Standard data syntaxes: XML, JPEG2000, others No implementations constraints: hardware/software neutral Closely based on ISO 191XX series of standards Additional architecture requirements to support GEOSS –Services are self-describing to support publish-find-bind –Multiple service types: catalog, portrayal, access, processing –Services chaining to support workflow

9 Major OGC Specifications for GEOSS Data access standards for web services Web Map Servers (WMS) Web Feature Servers (WFS) Web Coverage Servers (WCS) As well as the: Catalog Service for the (CSW) Web Map Context (WMC) Geography Markup Language (GML)

11 GEO Task AR Architecture Implementation Pilot Lead incorporation of contributed components consistent with the GEOSS Architecture… …using a GEOSS Web Portal and a GEOSS Clearinghouse search facility …to access services through GEOSS Interoperability Arrangements …support GEOSS Societal Benefit Areas Title from AR task sheet

12 Pilots seek collaboration in 3 areas 1.Development of scenarios in support of societal benefit areas to guide development and demonstration of the pilot services. 2.To contribute (and register) existing services, e.g, portals, catalogs and other services –both services hosted by the participants and solutions to be hosted by other organizations 3.Refine architecture; potential GEOSS Interoperability Arrangements

13 Set of GEOSS application scenarios Disaster: Wildfires Disaster: Tanker oil spill Climate Change: Local effects Ecosystems and biodiversity: Africa Ecosystems and biodiversity: Polar (IPY) Volcanic eruption planning and response: Asia

14 GEOSS Notional Architecture Standards Services GEOSS Registries Metadata cache Components

15 GEOSS Clearinghouse –Publicly accessible, network-distributed clearinghouse, –Subject to GEOSS interoperability specifications –GEO Task AR GEOSS Web Services (GWS) - proposed –Service Oriented Architecture for building on GEOSS Clearinghouse, GEOSS Portal and other GEO Tasks –Persistent network of publicly accessible services for demonstration, research, and operations consistent with interoperability arrangements in GEOSS –GWS as basis for demos and reference in GEOSS User Workshops

16 GEOSS-managed information resources GEOSS Components Registry GEOSS Services Registry GEOSS Standards Registry (external, hosted by IEEE) for service types, data formats, schemas, and other standards Identification of “special arrangements” (non-standard practice) GEOSS Clearinghouse

GEOSS Components GEOSS Services GEOSS Standards GEOSS Special Arrangements expose reference may become nominate GEO Members and Participating Organizations (GeoSec) offer GEOSS Registries GMU IEEE UDDIebRSCSW SRU Web UI External Standards Bodies Professional Organizations

18 GEOSS Web Portals General and adaptive user interface capabilities sought to organize access to GEO information Could be deployed as a GEO front-end to all GEOSS resources and SBA Could be re-deployed by any entity to provide standards based access to GEO-wide and community resources.

19 Web Portal Capabilities Functional Requirements –Support client access to catalogs, map services, and data services through standards-based interfaces –Provides user interface for search on the GEOSS Registry –Low/minimal cost of re-deployment –Readily customizable and extensible Nice-to-haves: –Community-management tools and portlets –Content management capabilities including teaching materials, documents –Ability to integrate multiple disparate resources and services –Place to reference or host end-user support applications

20 GEOSS Web Portals RFI issued to identify capabilities in late 2006 of re- deployable geospatial portals Call for Participation issued in early 2007 to identify offers of portal solutions Web Portal offers will be technically qualified in fall 2007 Opportunity for usability analysis and further user community engagement into 2008

25 What to watch for in the demos How the components operate –Services are distributed; not a monolithic workstation application –Services are interchangeable; plug & play using standard interfaces –Adherence to GEOSS architecture requirements Why it matters to GEOSS users –Easy, quick access to data: dramatic reduction in effort and time –Agile, flexible workflow allowing evaluation of different approaches –Enables collaboration: services accessed by variety of users –Pragmatic decision support Thanks to the GEOSS participants for developing the demo
