CREAF hosts the start of a project to improve the usability of global environmental data
18 February 2011
Centre de Recerca Ecològica i Aplicacions Forestals (CREAF)
The results of the project, co-funded by the European Commission and leaded by CREAF, will enable evaluation and mitigation of catastrophic environmental effects and provide a rigorous scientific basis for debates on controversial topics such as climate change.
In the Institut d'Estudis Catalans (Institute of Catalan Studies) CREAF hosted yesterday, 17th February 2011, the kick-off meeting of the new European project GeoViQua with a workshop consisting of all partners and a range of international experts. This project, leaded by the Catalan research centre, aims to develop a rigorous estimation framework for quality, uncertainty and usability of global environmental data and to disseminate the quality information to users via browsers and data viewers. Thus, when a catastrophic event occurs, as happened in Haiti last year, the right geospatial data can be quickly obtained allowing evaluating and mitigating ensuring that data quality is well characterised and thus the best information available is used.
The results of the project will have a global impact improving decision making and helping to solve global problems like climate change, catastrophic events or loss of biodiversity. The initiative is supported by the participation of 10 partners – among which a Catalan and two English Universities, French, Italian and German research centres, a Dutch company and the European Space Agency. The total budget is of about 4 million Euros; 3 million are funded by the European Commission.
GeoViQua will contribute to the development of the Global Earth Observation System of Systems (GEOSS) platforms. GEOSS is a project of initially 10 years duration (2005-2015) promoted by 85 countries worldwide and international organizations - for instance space agencies like NASA, ESA and JAXA. Its main objective is to create a global and public network of environmental data that is comprehensible and available in real time. GEOSS content and accessibility will have a global impact, enhancing the understanding of the dynamics of the planet and influencing environmental policies. The European Union funds the best initiatives, such as GeoViQua, in order to improve GEOSS and push its development further.
GeoViQua (the contraction of GEOSS Visualization and Quality) will take environmental data from international organizations like FAO, the World Meteorological Organization, or the European Environment Agency and will provide methodologies to enhance data documentation, formalizing quality parameters and metrics, and extracting them form data sources, validation procedures, or even though expert users’ comments.
During the processes of the creation of those datasets, strict protocols must be followed to determine the accuracy and usability of data. Unfortunately, in many cases this information remains only in the producer organization or it is not expressed in a widely accessible manner. In addition, new technologies as Internet map browsers, allow data to be made available to everyone and rapidly exchanged which sometimes leads to a loss of appreciation of the associated uncertainties with the risk of then using it in an inappropriate manner. These aspects are particularly relevant when the information is used in sensitive topics such as anthropogenic climate change.
GeoViQua will attach standard quality metadata to data making it available to users and experts which will produce more reliable studies about environmental systems and their dynamics.This project aims to contribute to a higher level of innovation to GEOSS project, increasing user confidence in the future information infrastructure.
These innovations will be centred on the development of quality enabled search engines and visualization portals. With the adoption of a GEO label that considers quality indicators, the task of communication and exploitation of the vast information resource represented by the GEOSS databases will be easier.All developed components in GeoViQua will be compatible with current geospatial standards, mass market map tools like Google Earth, other 3D visualization tools, and mobile devices.
