Anaglyph image of Tractus Catena
Anaglyph image of Tractus Catena
Anaglyph images can be created using data from the nadir channel of the High Resolution Stereo Camera (HRSC) camera system, the field of view of which is which is directed vertically down onto the Martian surface, and one of the four stereo channels, which are directed obliquely towards the surface. By using red/blue (cyan) or red/green glasses, a three-dimensional impression of the landscape can be obtained; north is to the right in the image. 3D glasses make it easy to see how the craters abruptly plunge into the depths with no evident rim – substantially different from impact craters. Because of the linear fractures, isolated dune fields can be seen. The flatness of the Tharsis highlands makes other faults running from west to east and the two grabens oriented from north to south strikingly clear.
