drivers of geoinformatics
K. Lehnert: Supporting Science & Education with GeoinformaticsDrivers of Geoinformatics
  • The need to handle an ever-increasing volume of Earth and space observation data.
  • The need to discover, access, integrate, and understand multi-disciplinary data in order to deal with more complex problems and respond more rapidly.
  • The need for processing power, storage, network bandwidth, and analysis tools to support data-based and data-intensive science.

  • Comprehensive data documentation (metadata)
    • Sample location, sampling process, description & classification, geological context
    • Analytical procedure and data quality
  • Interactive & dynamic user interface
    • Build customized data sets that integrate data across original disparate sources (publications, theses, unpublished data sets)
a typical question
K. Lehnert: Supporting Science & Education with GeoinformaticsA Typical Question
  • “Are high MgO basalts (MgO >8 wt%) from Lau Basin more enriched than high MgO basalts from the Mariana Trough?”
  • Query PetDB database
    • Set location: Lau Basin, Mariana Trough
    • Set sample type: Basalt
    • Set Chemistry Constraint: MgO > 8 wt%
    • Select data types: Trace elements, REE
  • Output data table (.txt, .xls) with data from >300 publications in ca. 2 minutes
success
K. Lehnert: Supporting Science & Education with GeoinformaticsSuccess
  • Hundreds of citations in the literature

concluding remarks
K. Lehnert: Supporting Science & Education with GeoinformaticsConcluding Remarks
  • GI is necessary to support Geoscience research & education.
  • While the number of GI systems is growing, coordination and integration of systems is insufficient.
  • Open access to scientific data is fundamental.
  • Organizational and cultural challenges need to be addressed to make GI a real science infrastructure.
  • Scientists and educators need to actively participate in the development of GI.
