Access to TerraSAR-X data for scientific use I
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 provision for the costs of fulfilling the user request / specific IPY handle
Announcement of Opportunity
Related to specific topics
Special conditions
Next AOs planned for
synergistic use with Rapid Eye
other SAR frequencies

Access to TerraSAR-X data for scientific use II
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

Access to TerraSAR-X data for scientific use in IPY
Join accepted proposals (requires agreement with PI):
A number of proposals referring to IPY existing with different status
Detailed overview within presentation of Dana Floricioiu (DLR)
Submission of new proposals
Further proposals possible at any time
IPY proposals still without cost
One coordinated proposal - to be discussed ??
Acquisition plan is set up by
Proposals and the respective ordering of acquisitions
Background mission

Data Policy
National security regulations established due to needs for international harmonization, e.g. for ITAR related issues
German law providing regulations in force
Satellitendatensicherheitsgesetz (Sat DSiG)
Definition for EO missions etc to be regulated by this law
Need for permissions of data distribution for DLR and Infoterra
Need for permission of operating mission
Defining regulations about users / people having access to the data
Defining “sensitive data” depending on resolution and phase information
Regulating urgency of the product provision (<10 days)

Conclusion
Data acquisition plan
Is set up indirectly by scientific proposal and the corresponding ordering of data
Your ordering drives what is acquired!
IPY proposal and intensified use is possible and welcome
Data Policy
Equal share of scientific and commercial use
Security regulations by law to be obeyed
