12. 12 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 Service-Oriented Architecture Principles Publish/Find/Bind XML technologies Interoperability InterfaceEncoding MetadataService Digital Rights MgmtCollaboration Extensibility Geo-scientific visualization Processing/Chaining Community support ExtensibilityInteroperability SOA ESG Architectural Principles

13. 13 ESG Characteristics Allows NASA specific search and publish capabilities e.g. keywords (Sea Surface Temp) data types (MOD02HKM MODIS/Terra Calibrated Radiances 5min L1B Swath 500m MO04MW) Extensibility and flexibility allow addition of future services and components specific to NASA Allows capability to rank NASA data sources first NASA maintained; allows adoption / adaptation to NASA specific requirements and Interoperable access to model products data types (HDF-EOS, NetCDF)  Search  Distributed or local searches  Harvest  Harvest from catalogs, clearinghouses, etc. (NSDI, GCMD)  Publish resources  Register metadata  Visualizations  Interactive viewer using publicly accessible standards (WMS)  Individual Accounts  Save map context files for future use, to share, to chain web services  Quick Links  Links to NASA web sites with mission, model, and science focus information and data products

14. 14 ESG Summary  NASA’s Earth Science Gateway (ESG) is gateway to advertising, finding, and accessing geoscience information services from many disparate sources.  Supports the science community through access to NASA research results  Extensible and flexible for changing standards and new services  Employs publicly accessible standards for maximum interoperability  Employs web services in support of Service Oriented Architectures  Is one system in the larger “System of Systems” concept Facilitation towards discovery of new information from disparate sources fosters interdisciplinary, exploratory, innovative and collaborative work

15. 15 Deployments of ESG OGC persistent GEOSS Network Demonstrations GMU Deployment to continue to test and advance based on COI requirements and evolving technologies ESIP Federation using ESG as backbone to EIE Portal and developing Societal Benefit Portlets Possible deployment to NASA’s RPC Environment Proposal to the GEOSS Architecture implementation pilot CFP

16. 16 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 NASA-related data by Increasing the opportunities to discover, access and integrate that data in the 12 national applications, particularly in non- traditional ways Access to data, observations and analytical models from diverse sources can facilitate interdisciplinary and exploratory research and analysis.

17. 17 Conclusion NASA Earth Science Gateway as an example platform that brings together the resources of the community to support larger contexts such as GEOSS ESG as a contributor to a robust, flexible, service-oriented, standards-based and extensible infrastructure ESG as a platform that can be used or built- on today to test the viability, usefulness and variations of the System of Systems architecture
