  1. Group on Earth bservations GEOSS Architecture

  2. Goals • Make it more efficient and more convenient for Applications partners to discover and access Earth Observations and research results • Create new opportunities for partners to leverage Earth Science research results with little to no additional effort required • Evolve portals to provide interoperability and access between research results and integrators • Leveraging current investments & capabilities • Working within the GEO System of Systems Concept

  3. Objectives • Employ Services Oriented Architecture • Implement publicly accessible geospatial interoperability standards • Extensibility & flexibility • e.g. new web services • 3D/4D viewers • Access Earth Observations Science components • Provide catalog search and data access functions to enhance Decision Support Systems

  4. OGC Interfaces Earth Science Components Knowledge Base Standard Browser, Web Mapping Portrayal Services WMS Digital Libraries WFS Models Processing Services 3D GeoBrowser ESMF Catalog Services Catalog Workstation Applications, Thick Clients WCS Grid Resources Mission Data Products EOS Catalogs ESG concept overview Earth Science Gateway Portal to data, information,knowledge about the Earth-Sun System Extensible, open service-oriented architecture

  5. ESG Architectural Principles • Enable the observing, processing, and dissemination methods provided by various parties while retaining their ownership and operational responsibilities. • Elements are themselves complex independent systems • Architecture should support wide range of environments, applications & processes Extensibility Geo-scientific visualization Processing/Chaining Community support SOA Interoperability Interface Encoding Metadata Service Digital Rights Mgmt Collaboration ESG Architectural Principles Interoperability Extensibility Service-Oriented Architecture Principles Publish/Find/Bind XML technologies

  6. Value of Interoperability • Ensure ability to access multiple, heterogeneous geoprocessing environments, either local or remote by means of open and standard software interfaces • Rely on open standards based interoperability • Interoperable interfaces on sources; data sources, in-situ sensors, models, registries, catalogs, etc. • Publicly accessible standards developed through consensus bodies (ISO, FGDC, OGC) • Increase the value of Earth-related data by • Increasing the opportunities to discover, access and integrate that data in the societal benefit areas • Access to data, observations and analytical models from diverse sources can facilitate interdisciplinary and exploratory research and analysis.
