Represents a COLOSSAL

investment by GEO Members &

PO in EO systems

Delivers major societal benefits to USERS, such as policy makers

& citizens

Enables GEOSS resources to be

readily discovered and accessed

Provides improved interoperability

Delivers trusted data & information

Is "Open”, in accordance with DSP

GCI Operational View


GEOSS Common Infrastructure provides

…a place where GEOSS-affiliated resources can be identified, found, and applied directly, or in support of one or more Societal Benefit Areas.

GEOSS Common Infrastructure

• GEO Web Portal Single access point to GEOSS related information and services.

• GEOSS Clearinghouse allows to search metadata, services, documents, ontologies, coordinate reference systems, and other resource types nominated within GEOSS via several interfaces with catalogues, databases, etc.

– Searchable via API from external clients such as the GEO Web Portal through a standard interface (OGC CSW 2.0.2)

• Components and Services Registry to register GEOSS resources of interest that will be then accessible through the GEOportal (e.g. via the Clearinghouse).

• Standards and Interoperability registry to configure systems so they can share information with other systems. A vital element to the ability of GEOSS to function as a true system of systems and provide integrated and cross-cutting information and services.

• Best Practices Wiki provides the GEOSS community with a means to propose, discuss and converge upon best practices in all fields of earth observation

GEO Web Portal


10

• Gateway to Global EO data, information and services that are of interest to the GEOSS user community.– Developed by ESA in collaboration with FAO (both GEO PO).

– Part of the GEOSS Common Infrastructure.

• Supports all the 9 SBAs and benefits of ESA and FAO experience in the relevant fields of application (e.g. Disasters, Climate, Agriculture, etc..).

• Operational and available at the link: http://www.geoportal.org. Operations started in November 2007 (GEO IV).

• Based on Open Source components, it can be freely installed and configured at GEO members’ premises (e.g. to create an SBA Portal).

ESA/FAO GEO Portal

GCI Current Status


12

Current GCI Status• GCI implementation & operations ruled by

GCI Consolidated Requirements 12 March 2009 [GCI REQ]

• Subset of GCI tested against [GCI REQ] (1st

half 2010): – Usability & Functional Testing of Web Portals

(GWPs), Clearinghouses (CLs) and Component & Service Registry (CSR)

• Test reports and several hours of videos available

– Single GWP and single CL selected


13

GEOSS Midterm Evaluation

• GEOSS represents an important new Earth observation community and network. GEOSS has raised visibility of the importance and need for integrated global Earth observations.

• :• GEOSS implementation has created a path to enable full and

open data sharing and lowered discussion barriers. • :

• Stakeholders perceive that architecture developed by GEO does not yet meet their needs for data, information, and tools.

• :


14

Basis for GCI Improvements


15

GCI Improvements• Since GCI testing, additional ideas for potential

improvements/GCI upgrade coming from ADC & GCI members– New Architecture and Data Strategies– AIP process / transferring outcomes and results to GCI

operations – GEOSS Data Sharing Principles needs for additional

information on data quality, data access / policy information, user registration, data tagging, etc..

– Way forward on QA4EO, Long Term Data Preservation– Potential new GCI Components suggested during 2nd GEO

Interop WS (Tubitak) e.g. Interop Service Brokers

Sources for GCI-extensions

• Requirements from SBAs and task-teams• Consolidated GCI requirements document• GEOSS data sharing action plan

– Still to be endorsed at plenary – Nov. 2010– E.g., req. on data quality, data access conditions,

etc.• Usability and functional testing reports• Strategic target for architecture and data management• New architecture and data strategies• GEO Web portal improvements


18

Main focus of/ideas for the proposal(GCI-centralised) – open to discussion

• Improving discovery, access and use of metadata, data, services and products with a focus on multi-disciplinary interoperability

Aspects:• Improving representation of data• Use of ontologies, standards, etc.• Processing / support to development and integration

of algorithms• Visualisation
