Priorities
NASA Initiatives

• Define and develop processing streams in support
  of environment/climate data records (third)
• Multiple science requirements for Landsat-class
  observations (to be developed based on
  participant submissions)
• New opportunities require new methodologies (RD)
• Ensure that NASAs needs for high resolution
  observations are met (weekly global clear
  imagery?)
• Undertake GLS 2010 (possibly using GEO Land
  Surface Imaging Constellation) (third)
• Explore opportunities for providing a global
  sample of very high resolution data (less than
  5m) in support of validation (fourth)
• Secure existing Landsat holdings from IGS
  (consolidate at EDC) (first)
• Achieve sustained consistent Landsat-class
  observations (second)
