Welcome
• On behalf of IEC and CREAF welcome to Barcelona and
the first GeoViQua workshop meeting

Institut d'Estudis Catalans
• Institute for Catalan Studies
• IEC was founded in 1907 to
undertake research and study
into "all elements of Catalan
culture”.
• The main building is located
at “La Casa de la
Convalescència”
(Convalescence House), a
17th century construction
related to an ancient Hospital
nearby. In 1931 the building
was severely transformed to
host the IEC.

Climate Change and
the Integrity of Science
We are deeply disturbed by the recent escalation of political assaults on
scientists in general and on climate scientists in particular. All citizens
should understand some basic scientific facts. There is always some
uncertainty associated with scientific conclusions; science never
absolutely proves anything. When someone says that society should
wait until scientists are absolutely certain before taking any action, it is
the same as saying society should never take action. For a problem as
potentially catastrophic as climate change, taking no action poses a
dangerous risk for our planet. […]

The aim
GeoViQua will provide a set
of scientifically developed
software components
and services that
facilitate the creation,
search and
visualization of
quality information
on EO data integrated
and validated in the GEOSS
Common Infrastructure.

Need for quality parameterization
• Poor quality data often led decision makers to overestimate
the amount of land needed for conservation areas.

GEOSS Strategic Targets
Data Management
Before 2015, GEO aims to:
2. Provide a shared, easily accessible, timely, sustained
stream of comprehensive data of documented quality, as
well as metadata and information products, for informed
decision making.
This will be achieved through:
Development of best practices, identified in the appropriate
GCI registry, for observation, collection and access to data
and information, including best practices for data quality
assurance for both observing system data and
information products

•
•
•
Quality parameterization and elicitation
Quality representation and visualization
Quality standards and frameworks
GEOSS architecture: portals, clearinghouses and pilots
Exploitation of GEOSS data in relevant communities
Needs from the CoP and uses in general
It is really important for use to capture the requirements of
that communities that will be afterwards elaborated in the
WP2 of the project

Project objectives
• 1. Provision of innovative tools to enhance the current
infrastructure capability.
– GeoViQua’s major technical innovation is search and visualization tools for
the community which communicate and exploit data quality information from
GEOSS catalogues.
• 2. Development of the GEOLabel.
– GEOLabel requirements are identified (Work Package WP2), integrated
with components (WP6), validated and applied into pilot cases (WP7), and
disseminated to the community (WP8). It will be completed in collaboration
with the GEO task ST-09-02.
• 3. Harmonization, exploitation and dissemination of project
outputs.
– A careful validation process is conducted in collaboration with a number of
communities of practice and standards committees to ensure that the
project contributes effectively to the GCI architecture. Collaboration to AIP
will be continuous.
