Bright Highlands And Dark Plains
This is a perspective view of the surface of Saturn's moon Titan near the Huygens probe landing site that includes the bright-dark boundary between the bright highlands and lower dark plains. This provides stereo coverage with a resolution of about 50 feet per pixel (roughly 15 meters) and a convergence angle of approximately 15 degrees. The perspective image is color-coded in altitude with blue lowest and red highest. The total relief is approximately 500 feet (roughly 150 meters) and the area covered is about 0.6 by 2 miles (1 by 3 kilometers). The valleys exhibiting dark drainages in the brighter higher, terrains have steep sides ranging up to approximately 30 degrees. A stereo pair of images (insert) was acquired from the Huygens descent imager/spectral radiometer. The left image was acquired from 9 miles (14.8 kilometers) above the surface with the high resolution imager; the right from 4 miles (6.7 kilometers) altitude with the medium resolution imager.

Pasadena CA (SPX) Dec 02 -- This perspective view shows dark plains on the surface of Saturn's moon Titan about 3 miles (5 kilometers) from the Huygens probe landing site. In this area many discrete bright feature are scattered across the dark plains. This provides stereo coverage with a resolution of about 45 feet per pixel (about 14 meters) and a convergence angle of about 6 degrees. The perspective image is color-coded in altitude with blue lowest and red highest. The ridges in the center of the view are about 150 feet-high (roughly 50 meters); the area covered is about 1.6 miles by 1.6 miles (2.5 by 2.5 kilometers). The topographic features toward the bottom right part of the view are suggestive of flow and erosion by fluids on the surface. A stereo pair of images (insert) was acquired from the Huygens descent imager/spectral radiometer. The left image was acquired from 8 miles (12.2 kilometers) above the surface with the high resolution imager; the right from 4 miles (6.9 kilometers) altitude with the medium resolution imager.
