    IS BIG DATA MORE THAN JUST ANOTHER BUZZWORD?

    BIG DATA GISCIENCE? KRZYSZTOF JANOWICZ, UCSB (FEB. 03 2012)

  • SOME THOUGHTS ON BIG DATA IN GISCIENCE...

    DO THESE BUZZWORDS SHARE A COMMON CORE?

    Digital Earth as a multi-thematic and multi-perspectiveknowledge archivee-Science as an infrastructure to share data and modelsand to enable collaborationSmart Dust as self-organizing, ubiquitous sensor networksLinked Data as a global graph connecting raw data to makethem accessible and re-usable

    Is Big Data a paradigm shift towards data-intensive,collaborative science in which models and data are shared?

  • SOME THOUGHTS ON BIG DATA IN GISCIENCE...

    THE THREE VS OF BIG DATA

    Volume: The size of the involved data, their multi-dimensionalnature, as well as their inter-linkage which creates a global graph.E.g., Volunteered Geographic Information, Location-based SocialNetworks, sensor networks, high resolution remote sensing data,complex transportation simulations. VVariety: The number of sources and type of data is increasing aswell. Combining social media with authoritative sources andintegrating different formats such as video, audio, photo, and textallows a more holistic analysis but raises new issues in dataintegration. VVelocity: Big Data is not only about large amounts of data but alsothe speed at which data is created and updated. A rapidlyincreasing number of data sources deliver near real-time datawhich poses new challenges for stream reasoning and rulesystems, which data do we keep? V

    KNOWLEDGE AS A NETWORK...

    ... The global Linked Data graph may be a promising knowledgeinfrastructure for Big Data.

    NSF EARTH CUBE

    NSF seeks [...] approaches to create integrated data managementinfrastructures across the Geosciences. [...] recognize the multifacetedchallenges of modern, data-intensive science and education and envisionan environment where low adoption thresholds and new capabilities acttogether to greatly increase the productivity and capability of researchers andeducators [...].
