Guide to Magellan Image
Interpretation
Figure 4-4. Stereo image pair showing complex ridge
terrain and a smooth-floored depression in the Ovda region of
Aphrodite Terra: (a) Cycle 1 image with illumination from the left at
an incidence angle of 43 deg; (b) Cycle 2 image with illumination
from the left at an incidence angle of 23 deg. Cycle 2 data were
acquired during the stereo test orbits 2674 through 2681. The total
relief in this scene is about 2.6 km; the center coordinates are
8°S, 74°E. Perception of relief may be obtained with stereo
glasses or a stereoscope. Some individuals may be able to fuse the
images without the aid of these devices.
