Most of the SIR-C Survey Data from SRL-1 and SRL-2 are now on-line at the the Eros Data Center (EDC)! SIR-C Survey Data is low resolution (50 meter pixel spacing), single frequency (usually L-band) and single polarization (usually HH) byte data. Even though this data is not the highest resolution, and is only single channel (just a black and white image), this is a very useful resource. It is available free, it is available now, and it is available over the internet!
If you need either better resolution (up to 5 meter pixel spacing), or more channels (such as was used to make the color pictures in the picture gallery), then you can request that data be processed for you (for free!) by becoming part of our outreach program! In order for you to get data processed, you will have to justify the need.
Here is a list of addresses, and in some cases telephone, fax, or email
addresses to contacts for imaging radar data from a multitude of
missions.
(of course, there are also the sample radar images that are available, as well as the pictures in the picture gallery).
