Access to TerraSAR-X data for scientific use

• Data policy issues
• Commercial exploitation EADS-Astrium
• Scientific utilization DLR
• Both parties equally share the satellite
  resources gt proposal
• National security regulations
• Satellitendatensicherheitsgesetz (Sat DSiG)
• Users / people having access to the data
• Resolution and phase information
• Urgency of the product provision (lt10 days)

15
Access to TerraSAR-X data for scientific use

• The status is gained via a selection process
• proposal submission
• evaluation (mission objectives, data
  requirements, scientific use criteria)
• General proposal submission (since October 2007)
• Submission at any time
• Data are provided for the costs of fulfilling the
  user request
• Announcement of Opportunity
• Related to specific topics
• Special conditions
• Next AOs planned for
• synergistic use with Rapid Eye
• other SAR frequencies

16
Access to TerraSAR-X data for scientific use

• Accepted proposals
• Creation of a proposal specific user account
• quota of products for the agreed purpose.
• priority
• The provision of data requires
• the signature of the user license agreement
• the list of people having access to the
  TerraSAR-X data
• the confirmation of the corresponding funding

17
Access to TerraSAR-X data for scientific use in
IPY

• Join accepted proposals (requires agreement with
  PI)
• COA0195 Ronald Saper (Vantage Point
  International)
• HYD0270 Alexander Braun (Uni Calgary)
• LAN0013 Mathias Braun (Uni Bonn)
