QUAlity aware VIsualisation for the Global Earth Observation System of Systems (GEOSS)

Time frame: 02.2011 to 01.2014

Description: 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 from data sources, validation procedures, or even through 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.
