As CEOS Earth Observations grow in both quantity and variety, users face increasing challenges in finding the most appropriate data for their use.  Ranking data search results by their expected relevance for the user is potentially one of the most powerful ways to help users quickly zero in on the best data for their purpose. This webinar will look at some of the techniques being used within Earth Observation data search tools, followed by a discussion of possible future directions in relevancy ranking.
