An European Approach to GEOSS
Short Description
The EuroGEOSS project will demonstrate the added scientific value of making existing systems and applications interoperable and used within the GEOSS and INSPIRE frameworks. Focus will be on the application areas (Drought, Forest and Biodiversity), and the multi-disciplinary interoperability aspects to opening them up, linking them, and making them GEOSS components. Demonstration will be made that through this process increased access to new forms of data and services are enabled, and as a result new scientific questions can be addressed, or old questions can be addressed in new and better ways.
GEOTEC’s contribution
GEOTEC led the 'alternative discovery mechanism for geospatial resources' task of the EuroGEOSS project, which investigated new ways and implemented a brokered tool (called Web 2.0 Broker) to perform spatio-temporal queries over Web 2.0 resources and social network sites. GEOTEC coorganised and actively participated in the final EUROGEOSS conference to show the main results achieved over the course of the project.
