The Earth Below: Purchasing Science Data and the Role of Public-Private Partnership

Bookmark and Share Report Misuse or Glitches


The Science Data Purchase Program, commonly known as the Science Data Buy (SDB), has been a success in supplying commercial remote sensing data that serves NASA science requirements, but plans for its continuation are uncertain. Although NASA has said that it will purchase science data when it is cost-effective to do so, rather than build new satellites, there is little guidance on determining cost effectiveness. This study was organized to examine public-private partnerships in remote sensing, metrics for evaluating such partnerships, the types of partnerships that might be most appropriate for NASA’s Earth Science Enterprise, and options for the future of NASA’s SDB. The authors conclude that the “data clearinghouse” is likely to be the most appropriate partnership model for acquiring, maintaining, and distributing data from many sources to many different users. The authors caution that NASA needs to understand and choose what kind of buyer of private remote sensing data it wants to be before it develops specific cost-effectiveness metrics, and that it should clearly articulate the role of the SDB with respect to an overall strategy for earth science research.
