This image depicts the coastline along the Everglades National Park. It was acquired by NASA’s UAVSAR instrument, flown aboard a Gulfstream III on June 15, 2009. The polarimetric SAR data has been processed to yield a Yamagu-chi decomposition, that depicts the physical structure of targets. In this RGB image, red portrays microwaves that have undergone double bounce from water to tree, green portrays microwaves that have scattered off vegetation, and blue portrays microwaves that have bounced off a surface.

The ASF SAR Data Center is located in the Geophysical Institute at the University of Alaska, Fairbanks. The ASF SDC is supported by NASA to acquire, process, archive, and distribute Synthetic Aperture Radar (SAR) data from polar orbiting satellites and airborne sensors to advance Earth science research.  ASF archives data from the Canadian RADARSAT-1, European Remote Sensing Satellilte-2 (ERS-2), the Japanese ALOS PALSAR, European Remote Sensing Satellite-1(ERS-1) and Japanese Earth Resource Satellite-1 (JERS-1). In addition, ASF archives and distributes AirSAR and UAVSAR—two airborne SAR sensors operated by NASA. The ASF SDC archives data from around the world. Because these data products are derived from satellites owned by NASA’s international partner flight agencies, most data is restricted and available only to NASA- approved researchers. Interested users may obtain access by submitting a proposal to uso@asf.alaska.edu. Proposal guidelines can be found at: http://www.asf.alaska.edu/program/sdc/proposals

The UAVSAR and AirSAR data products, along with other unrestricted data products are available for direct download through  Vertex:ASF’s Data Portal at https://vertex.daac.asf.alaska.edu/.

Data Access

Online access to ASF SAR Data Center data is available through the REVERB data search and order system and the ASF Data Portal, Vertex at https://vertex.daac.asf.alaska.edu.
