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.
