Much of the SAR data in the ASF SDC archive is limited in distribution to the United States' scientific research community and U.S. Government Agencies. In accordance with the Memoranda of Understanding (MOU) between the relevant flight agencies (CSA, ESA, JAXA) and the U.S. State Department, the ASF SDC does not distribute SAR data for commercial use. Access to AIRSAR and UAVSAR does not require a proposal.
The SDC offers three types of proposals for accessing SAR data which are:
The NASA 2-Page Proposal is required to access archived ERS-1, ERS-2, JERS-1, and RADARSAT-1 data. No funding is available through this mechanism to support data analysis, although data processing costs at the SDC are covered. You must be a resident of the United States to receive approval for data access.
The Student Access Proposal provides an opportunity for students and professors to access SAR data for class projects and theses. This opportunity applies only to ERS-1, ERS-2, JERS-1, and RADARSAT-1 data currently in the SDC catalog.
There are limits on the number of data products that can be obtained through this process. The maximum number of Detected images allowed is 50 and the maximum number of Level 0 products or Complex images is 16. If more data is required, a standard NASA 2-Page Proposal should be submitted. You must be a resident of the United States to receive approval for data access.
ALOS PALSAR data is available from the SAR Data Center by placing a proposal through the User-Proposal Application System (UPASS). An approved proposal allows access to any PALSAR data archived within the SDC. You must be a resident of the United States to receive approval for data access.
