            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

       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.
