  • 1. David Van Riper RDAP14, San Diego March 27, 2014
  • 2. TerraPop Goals Lower barriers to conducting interdisciplinary human- environment interactions research by making data with different formats from different scientific domains easily interoperable Provide an organizational and technical framework to preserve, integrate, disseminate, and analyze global- scale spatiotemporal data describing population and the environment.
  • 3. TerraPop in Context Collaborating Organizations • Data integration expertise • Large census and survey data collections & expertise • Institutional foundation • Human-environment interactions research expertise • Environmentally-oriented data collections & expertise • Data preservation and sustainability expertise • Social science data collections & expertise • Major producers and distributors of data on both humans and their environment • Major producers of tools for integrating and transforming data across formats • Leaders in preservation and sustainability
  • 4. TerraPop in Context DataNet Cyberinfrastructure Curated population and environment data collection  Exposed through DataONE, SEAD  Extracts exportable to DFC Integration services  Potentially available through DFC, SEAD  Open source components and API

  • 12. Future Plans
  • 13. Collection Expansion  Add more census/survey data  Add more global environmental data  Add more GIS mapping files  Develop data curation protocol(s) for adding additional data to TerraPop  Develop mechanisms for scholars to deposit data/metadata into TerraPop  Allow others’ data to be integrated with other TerraPop data
  • 14. Upcoming Activities  Beta system public release – soon!  User interface redesign for Fall 2014  Conference workshops  IASSIST – Toronto – June 3, 2014  Population Association of America – Boston – April 30, 2014  More to come in last 2014/early 2015  Become a DataONE member node  Continue working with SEAD and DFC on potential collaborations
