GEOSS Core ArchitectureInitial Operating Capability (IOC)
• Core Architecture– GEO Web Portal, Clearinghouse, and Registry – Process to register, discover and use services – GEOSS Interoperability Arrangements
• During 2007, GEO ADC guided development of IOC through its core tasks:– AR-07-01 - Enabling Deployment of Architecture– AR-07-02 - Architecture Implementation Pilot
• Results demonstrated at EO Summit and GEO-IV

GEOSS Engineering Architecture
![Page 10: GEO Architecture and Data Committee Architecture Workshop](https://reader036.fdocuments.in/reader036/viewer/2022062519/56815454550346895dc26a3a/html5/thumbnails/10.jpg)
GEOSS Architecture
• Initial Operating Capability (IOC) established• 64 Components & 75 Services registered (21 Nov 07)• GEO Web Portals (3), Community Portals (27) and
Decision Support Clients (13) for User access to services
• Several organizations capable of providing – GEO Web Portal solutions– GEOSS Clearinghouse solutions
![Page 11: GEO Architecture and Data Committee Architecture Workshop](https://reader036.fdocuments.in/reader036/viewer/2022062519/56815454550346895dc26a3a/html5/thumbnails/11.jpg)
GEO Web Portal
• Demonstrated that organizations are capable of providing workable GEO Web Portal solutions– Compusult: http://www.geowebportal.org – ESA-FAO: http://www.geoportal.org– ESRI: http://keel.esri.com/Portal
• Though visibly similar & meeting basic requirements, the three offer different feature sets.
• Cape Town Declaration: “We commit to explore ways and means for the sustained operations of the shared architectural GEOSS components and related information infrastructure.”

GEOSS Architecture - Further Development
• Increase collaboration with GEO Committees, Communities of Practice and relevant GEO Tasks.
• Increase commitment to Operational requirements to support persistence– Portal, Clearinghouse and other services
• Add Sensor Component Types– Task, acquire and process observations– Inter-calibration scenario, e.g., CEOS
• Workflow for observation processing and decision support, e.g., Fed Earth Observation (FedEO) pilot

Breakout Sessions – User/Developer’s Perspective
Sample Questions– What is a user?– What are the needs and concerns for GEOSS
from a user perspective?– What are the most important information from
GEOSS for user applications?– If the architecture is developed over a number of
years, what features should be developed early?– What features are missing that you would like to
see included
![Page 22: GEO Architecture and Data Committee Architecture Workshop](https://reader036.fdocuments.in/reader036/viewer/2022062519/56815454550346895dc26a3a/html5/thumbnails/22.jpg)
Breakout Sessions – Summary Findings I
• A spectrum of Users– End Users (Top level Decision/policy makers, managers) in
need of user friendly information– Researchers more focused on source and quality of data– Accommodate different needs & level of expertise
• Users versus Providers– Encourage connectivity between the two and between
models and data providers– Iterative, interactive feedback from users & ability to correct
errors• Models
– Need for interoperable cross-domain models– Improved connection between modeling and observation
communities
![Page 23: GEO Architecture and Data Committee Architecture Workshop](https://reader036.fdocuments.in/reader036/viewer/2022062519/56815454550346895dc26a3a/html5/thumbnails/23.jpg)
Breakout Sessions – Summary findings IIEmphasis on Data• Key data characteristics
– Discovery, accessibility, distribution, visualization/layering, sharing• Data packaging
– Clear documentation – especially when cutting across benefit areas– Standards– Meta-data
• Frequently mentioned concerns– Timeliness (from real time to paleo-data)– Security/authentication (access to proprietary data...)– Quality (Trusted source; Quality Assurance and Control; Data lineage)– Continuity of data source– Compatibility– Sharing policies
• Data distribution mechanism– Internet vs mobile access (including ad-hoc networking)– Feedback mechanism
![Page 24: GEO Architecture and Data Committee Architecture Workshop](https://reader036.fdocuments.in/reader036/viewer/2022062519/56815454550346895dc26a3a/html5/thumbnails/24.jpg)
Breakout Sessions – Summary Findings III
• SoS Architecture key desired characteristics– Offer simple, seamless services– Supports high availability, reliability, security, authentication– Facilitate interoperability– Allows for technology evolution & new technology insertion
• Thoughts on interoperability• Focus on connecting systems within a community• Interfaces are abstracted in “wrappers” developed cooperatively
by Providers & Users• Include ontology in Interoperability registry
• Build a little, test a little: demonstrations, prototypes and pilots are essential
