Comparing GEOSS with WDS • GEOSS
– Application (SBA’s) user driven; broad range of user communities, but rather apparent (e.g. “fighting with drought”)
– Need to handle very heterogeneous data sets – No direct control of data quality – Simple discovery of data is focused.
• WDS – Science driven; scientific users – Each center handles “homogeneous” data with better
quality control. – More advanced data discovery is under development (e.g.
ontology-based data search like PANGAEA etc.)
