  • 1. An On-line Collaborative Platform for Earth Observation Scientists John Gamon Cameron Kiddle Arturo Sanchez-Azofeifa Roger Curry Benoit Rivard Nayden Markatchev Gilberto Zonta Pastorello Jr. Rob Simmonds Arie Croitoru Tingxi Tan
  • 2.
    • An on-line platform for Earth Observation Scientists
      • Facilitating:
        • Collaboration between scientists
        • Application access, management and sharing
        • Data access, management and sharing
      • Leveraging:
        • Web 2.0 and social networking technologies
        • Cloud computing technologies
        • Semantic Web technologies
      • Funded by:
        • CANARIE - Network Enabled Platform (NEP-1) program
        • Cybera
    ( http://geochronos.org/ ) AGU 091214
  • 3. Motivation
    • Scientific Gateways
      • Aim to enable collaboration and transparent access to data and computational resources
    • Social Networking
      • Can enhance collaboration capabilities around data and applications – “ Facebook for Scientists ”
      • Facebook Widely adopted
          • > 300 million users (50% log on to Facebook on any given day)
          • > 1 billion chat messages per day
          • > 2 billion photos, 14 million videos uploaded per month
          • > 350 thousand applications on Facebook Platform
    AGU 091214
  • 4.
    • Based around “Groups” with common interests
    • Technology
      • Portal built on top of a social networking platform Elgg ( http://www.elgg.org )
        • Tags, bookmarks, profiles, blogs, wikis
        • Friends/contacts, groups
        • Discussions, message boards, calendars
        • Status, activity feeds
      • Interactive Applications
      • Cloud Computing
    Collaboration AGU 091214
  • 5. Dashboard AGU 091214
  • 6. “ Groups” within GeoChronos AGU 091214
  • 7. Groups - Example: Wireless Sensor Network Summer School AGU 091214
  • 8.
    • Interactive Application Service (IAS)
      • On-line, on-demand access to scientific applications
      • Share application sessions and data with other users
    • Hosted on a cloud computing platform
      • Use ASPEN ( http://grid.ucalgary.ca/projects/DataCentre/ )
      • dynamically provision virtual machines to host applications
    • Batch processing and automated workflow services (Work in Progress)
      • Handle longer running data processing tasks and simulations
      • Automate data workflows involving data acquisition and transformation of data into different data products more suitable for use by scientists (e.g., mosaic, reproject and subset MODIS data)
    Applications AGU 091214
  • 9. Application Catalogue AGU 091214
  • 10. Interactive Application Service (IAS) Example - TIMESAT AGU 091214
  • 11.
    • Technology
      • iRODS ( http://www.irods.org/ ) for data storage/management
      • Semantic Web technologies such as RDF (Resource Description Framework) to link/relate data
    • Examples
      • Spectral Libraries
        • Store, share and browse spectral data
        • View spectral plots, metadata, ancillary data and maps
        • Manage and generate metadata for spectra
        • Create and share metadata schemas
      • Generalization of spectral library solution for other types of data (work in progress)
    Data AGU 091214
  • 12. Spectral Library – Browse Spectra AGU 091214
  • 13. Spectral Library – View Metadata AGU 091214
  • 14. Vegetation Spectral Library AGU 091214 Example courtesy Santonu Goswami, Univ. Texas, El Paso
  • 15. Vegetation Library – Metadata AGU 091214
  • 16. Spectral Library – Ancillary data AGU 091214 Example courtesy Santonu Goswami, Univ. Texas, El Paso
  • 17. Spectral Library – Location Map AGU 091214
  • 18. Portal Usage
    • Over 70 users from Europe, South America and North America
    • Used at IAI International Wireless Sensor Networking Summer School in Edmonton in July 2009 (~40 participants)
    • On-going usage by Tropi-Dry community for collaboration and sharing documents
    • Slowly opening up portal to different communities of users as development progresses
