GEOWOW is enhancing GEOSS by acting on two levels: on one hand, by developing the infrastructure functionalities needed to improve data discovery, access and exploitation; on the other hand, by promoting the GEOSS Data Collection of Open Resources for Everyone (GEOSS Data-CORE), a distributed pool of documented datasets with full, open and unrestricted access at no more than the cost of reproduction and distribution. GEOWOW partners are invited to encourage their data-providing organizations to make available datasets that fall into this category.
Data Discovery and Access
The GEO Discovery and Access Broker (GEO DAB) was adopted by the GEO Plenary in 2011 as a key innovation to extend the number of capacities and data resources accessible through the GEOSS Common Infrastructure. The novelty of this approach is that it builds the necessary bridges across different thematic communities without asking them to change their ways of working, including making changes to the standards and protocols that they use. GEOWOW extends the brokering framework with ranking of search results, semantic searching capabilities and improved access to data, services, and models.
Data exploitation capabilities - the Developer Cloud Sandbox, are developed by GEOWOW partners, enabling GEOSS users to access and process data on the Cloud, from their facilities. GEOWOW provides virtualized work environments and the necessary interfaces to leverage the computing resources of Cloud providers. Key features are the support to development and validation of Earth Science models, the facilitated access to large Earth Science data repositories, as well as the publication and reuse of scientific datasets, algorithms and processing chains to reproduce experiments or adapt them to new contexts. This offers important opportunities for GEOSS to move beyond data discovery improvements, and brings GEOSS users to computational science for data intensive analysis.
A subset of river discharge data from the Global Runoff Data Centre (GRDC) is made freely available as GEOSS Data-CORE and discoverable in standardized formats via the GEOSS Portal. Currently, 235 of the GRDC gauging stations are part of the GEOSS Data-CORE. On-going efforts are undertaken to make more GRDC stations available. A future contribution to the GEOSS Data-CORE is the annual modelling results of “Global Freshwater Fluxes to the Oceans”. The related data products are expected to be available from mid-2014.
GEOWOW has received funding from the European Community’s Seventh Framework Programme (FP7/2007-2013) under grant agreement n° 282915
