A portion of Western Eistla Regio is displayed in this three-
dimensional perspective view of the surface of Venus.  The
viewpoint is located 725 kilometers (450 miles) southeast of Gula
Mons, at an elevation of 1.2 kilometers (0.74 miles).  A rift
valley, shown in the foreground, extends to the base of Gula
Mons, a 3 kilometer (1.86 miles) high volcano.  We are looking to
the northwest with Gula Mons appearing at the right on the
horizon.  Gula Mons is located at approximately 22 degrees north
359 degrees east.  Sif Mons, a volcano with a diameter of 300
kilometers (180 miles) and a height of 2 kilometers (1.2 miles),
appears to the left of Gula Mons in the background.  Magellan
synthetic aperture radar data is combined with radar altimetry to
develop a three-dimensional map of the surface.  Ray tracing is
used to generate a perspective view from this map.  The vertical
scale is exaggerated approximately 23 times.  Simulated color and
a digital elevation map developed by the U. S. Geological Survery
are used to enhance small scale structure.  The simulated hues
are based on color images recorded by the Soviet Venera 13 and 14
spacecraft.  The image was produced at the JPL Multimission Image
Processing Laboratory by Eric De Jong, Jeff Hall, and Myche
McAuley, and is a single frame from the movie released at the
March 5, 1991, press conference.
