Objectives
• To allow an easy and harmonised access to heterogeneous resources
• To develop services for data discovery, access, and use establishing and promoting data sharing
• Facilitate geo-resources sharing
• Facilitate geo-resources access
• Contribute to GCI enhancement
• Develop GCI operational capabilities for the project’s SBAs

Observations Products Information
Today, the GCI (GEOSS Common Infrastructure) is designed to support onlya limited number of user typologies.
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
Requirements
Digital Earth CommunitiesTowards a GEOWOW vision
•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.
Digital Earth Communities
03/05/2012 IIB meeting - Geneva
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.
Priority functionalities
Digital Earth Communities
• GEOWOW has analysed important key technologies, establishing a pool of solutions and ideas
• 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, …)
Landscape
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.
Architecture flexibility
Digital Earth CommunitiesUsage patterns
• 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.

Usage patterns
Digital Earth Communities
Interferograms computed from satellite data (either on demand computation or discovery of previously
generated products)
In- Situ data
Satellite data
Query of heterogeneous observations, products, information
An example of use case
Semantic enriched search
Tools for geoprocessing
Registration of results
Just an example of use case from several usage patterns that will be possible according to user needs
Digital Earth Communities
• 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.
Preliminary identified components
Digital Earth Communities
In a nutshell: seamless discovery and access to…
satellite data
airborne data
in-situ data
mapsmodels
processing services
documentation
metadata
…for all the identified GEOSS users according to different usage patterns…
… with special focus on GEOSS Data CORE
