Digital Earth Communities

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

…for all the identified GEOSS users according to different usage patterns…

… with special focus on GEOSS Data CORE
