Query previews in networked information systems - the case of EOSDIS



Query Previews allow users to rapidly gain an understanding of the content and scope of a digital data collection. These previews present overviews of abstracted metadata enabling users to rapidly and dynamically avoid undesired data. This video summarizes our work on developing query previews for NASA Earth Science data. New developments include approaches that successfully address the challenge of multi-valued attribute data. Memory requirements and processing time associated with running these new solutions remain independent of the number of records in the dataset.
