Magellan SAR and synthetic stereo mosaics by quadrangle

9 September 2013
The Magellan SAR and Synthetic Stereo Mosaics were created back in 2002 by Vicki Hansen and Duncan Young at the University of Minnesota, Duluth. These are just visual Jpegs and currently do not have geospatial headers for mapping applications. Description: synthetic aperture radar (SAR, cycles 1, 2, or 3) and altimetry data from the NASA Magellan mission (1991 – 1994) can be digitally combined to create synthetic stereo images. Because SAR and altimetry cycles image ~98% of the planet (Kirk et al., 1992), synthetic stereo can be created globally except at the poles. The stereo pairs are viewed as color (red-blue) anaglyphs. Red color projects the combined SAR images from both cycles, and the blue color projects the distorted image to produce a red-blue anaglyph.  You can currently view and download the images from here: ftp://pdsimage2.wr.usgs.gov/pub/pigpen/venus/MagellanSARimages_SyntheticStereo/
