  • 5. Virtual Organization NEP-1 Synergy Workshop April 21, 2009 GeoChronos -
  • 6. Collaboration Challenges
    • Familiarity with new tools for collaboration
    • Keeping all interested parties in the loop
    • Finding related work and researchers
    • Keeping up to date with current research
    • Collaboration while working in the field
    NEP-1 Synergy Workshop April 21, 2009 GeoChronos -
  • 7. Data Challenges
    • Acquisition of data
      • Many different data sources
      • Different regulations/mechanisms for accessing data
      • Lack of automation
      • Finding the right data
    • Managing data
      • Scattered and unorganized data
      • Inadequate tools for recording/maintaining metadata
        • Data without metadata is meaningless
        • Lack of suitable metadata standards
        • Validation of metadata
      • Tracking provenance of data
    • Pre-processing of data
      • Raw data typically cannot be directly analyzed
      • Significant amount of time spent preparing data for analysis
      • Lack of automation
    NEP-1 Synergy Workshop April 21, 2009 GeoChronos -
  • 8. Application Challenges
    • Access to software available in research lab while in field or other locations
    • Installing, configuring and updating software
    • System dependencies of software
    • Awareness and suitability of available software
    • Sharing applications
    • Getting help in using applications
    • Sharing results and getting feedback
    • Co-location of data and applications
