Information
Today, the GCI (GEOSS Common Infrastructure) is designed to support only
a limited number of user typologies.
Requirements
Digital Earth Communities
•Initial set of user communities and multidisciplinary
requirements identified by the GEOWOW partners:
•MULTIDISCIPLINARY REQUIREMENTS
•REQUIREMENTS FROM SBAs
•Requirements from external sources, like projects and
Architecture Implementation Pilot (AIP) processes
Towards a GEOWOW vision
Digital Earth Communities
•A long-term vision for the GCI evolution,
in agreement with the IIB.
•This will include not only components
developed by GEOWOW itself, but also
external elements.

Priority functionalities
Digital Earth Communities
•Improved data discovery including results ranking;
•Easier data access;
•Interface of GCI components from external clients,
including two ways communication;
•Improved data usability, including harmonization and
geoprocessing services;
•New data registration mechanisms, including support for
the GEOSS Data CORE
•Solutions and tools for user registration authorization
authentication including single sign-on.
Landscape
Digital Earth Communities
•GEOWOW has analysed important key
establishing a pool of solutions and ideas
technologies,
•A preliminary analysis has been conducted to map
identified
requirements
to
analysed
projects
(EuroGEOSS, UncertWeb, GENESI-DEC, GeoViQua, Eye on
Earth and the current GEOSS Common Infrastructure, …)
Architecture flexibility
Digital Earth Communities
•The landscape of technologies is in continuous evolution
 architecture flexibility is a key requirement.
•The design of the GEOWOW Architecture shall therefore
follow a modular approach. It shall result in a set of “GCI
Evolutions”, i.e. interoperable components that respond to
the community needs and are able to fit into the existing
landscape, however rapidly this is evolving.
Usage patterns
Digital Earth Communities
•The proposed architecture will result as flexible as possible
and different communities will benefit from it in
different manners, according to their needs and their
usual working habits.

An example of use case
Digital Earth Communities
Semantic enriched search
Query of heterogeneous observations,
products, information
Just an example of use case from several usage patterns that will be
possible according to user needs
Satellite data
In- Situ data
Tools for geoprocessing
Registration of results
Interferograms computed from satellite data (either
on demand computation or discovery of previously
generated products)
Digital Earth Communities
Preliminary identified
components
•Components for Enhancing Data Discovery and Access
including:
•Result Ranking;
•Semantic enriched search;
•Geoprocessing components;
•User registration components and tools for authentication
(user personal information will not be registered at
GEOWOW side);
•Resources Registration facilitators to improve the
GEOSS Data CORE availability;
•Components for enabling community specific clients to
access GEOSS resources.
Digital Earth Communities
In a nutshell: seamless discovery and
access to…
satellite data
metadata
airborne data
documentation
processing
services
in-situ data
models
maps
…for all the identified GEOSS users
according to different usage patterns…
… with special focus on GEOSS Data CORE
