11. Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum Folie 11 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

12. Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum Folie 12 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

13. Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum Folie 13 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

14. Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum Folie 14 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)

16. Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum Folie 16 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
