GEOSS Common
Infrastructure (1)
The Global Earth Observation System of Systems (GEOSS) consists of a
global and flexible network of content providers and aims at providing
decision-support tools to a wide variety of users.
A set of core components and
functions, known as the GEOSS
Common Infrastructure or GCI,
were designed and deployed to:
•
•
•
Allow GEOSS resources (e.g.
systems, data, services) to be
easily discovered and accessed.
Improve interoperability for existing
and future observation systems.
Build an Open Infrastructure in
accordance with the GEOSS Data
Sharing Principles.
GEOSS Common
Infrastructure (2)
Based on the GEOSS 10-year implementation plan, the GEOSS Common
Infrastructure (GCI) offers the following capabilities:
• A Web Portal that provides GEOSS users
with a “one-stop” discovery and access
function to all GEOSS resources;
• A brokering-based architecture to discover
and access registered resources;
• A set of registries of GEOSS components,
services, standards, requirements and
best practices.
As main enabler of the System of Systems principles and capabilities, the
GCI is able to interface with external systems to facilitate end users in
discovering and accessing their services and resources.

GEOSS resources search
in GEO Web Portal through:
• Free text
• Browsing via Societal
Benefit Areas (SBAs)
• Semantic search
• Refined search
• Distributed search of
catalogues and
inventories via Data
Access Broker.
• Direct access to data &
resources.

IN-03 GCI
Task Description
• Facilitate and support the sustained operation, maintenance and
enhancement of a user-friendly GCI, allowing users to search and access
GEOSS resources (e.g. datasets and services).
• Support the integration of new GCI capabilities and the discovery of, and
access to, a core set of data and information across all SBAs.
• Continuously engage with GCI core service operators, data and service
providers, and user communities.
• Two task components:
– C1: Evolution and Enhancement of the GCI
– C2: Operations and Maintenance of GCI Components
• Addressing Architecture and Data Management Strategic Targets
• Task Coordinators and PoCs: M. Albani (ESA) and D. Nebert (USGS)
IN-03
Coordination Mechanism
• GCI operations are conducted by the GCI Operations Team within
Component C2 (GCI Operations) under the coordination of the C2
Component Point of Contact.
• GCI enhancements are assessed and implemented by the GCI
Enhancement Team within Component C1 (GCI Enhancements)
under the coordination of the C1 component Point of Contact.
• Feedback from user possible through the GWP.
• Supporting Tools implemented:
– GCI Operations and Evolution (GOE) tool to handle process for
GCI bugs resolution and enhancements implementation.
– MONITIS.COM tool: web server monitoring of GCI operations
• Regular bi-weekly Telecons ongoing (Operations + Enhancements)
among GCI providers.
–
Extension of participation to data-CORE Providers in case of need to facilitate discovery and
accessibility of data.
–
Infrastructure Implementation Board provides advice and guidance.
Work-in-Progress
Future work will aim at:
•Increasing the number of resources (including GEOSS Data-Core)
discoverable and accessible through the GCI.
– Facilitation of GEOSS registration mechanism
– Enhance access to resources (also not registered in GEOSS)
– Engagement and support from resource owners needed
•Further consolidating GCI components, interfaces and functions
– Improve integration of search and access components
– Improve data visualization in the GWP
– Improve result ranking algorithm such that sorting of results reflects the expected ‘best
match’of an item based on the query
– Improve semantic search, to address the semantic heterogeneity among the
terminology
– Enhance service checking for GEOSS resources
– User registration
•Integrating new elements and components in the GCI
