Important Note About the C-Band Radar Data Image Products The radar data products currently being released are generated from preliminary Digital Elevation Maps (DEM). Products made from the preliminary DEMs are uncalibrated and are released with the understanding that they are merely "showpiece" products. It is expected to take two years to generate the final precision Digital Elevation Map. About the Anaglyph Data Products When viewed through special glasses, anaglyphs will allow you to see a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter. 3D Glasses Direct is an online source for 3D glasses. They will even send you a free pair of paper 3D glasses when you send them a stamped self-addressed envelope. About the Stereo Pair Data Products The stereo-pair images are reversed; that is to say, the "left-eye" image is on the right side of the pair. This is intentional. It is set up for cross-eyed viewing, as indicated on the image.
