TOPSAR digital elevation model for Fernandina (118K image)
Investigators at the Jet Propulsion Laboratory and the University of Hawaii are collaborating on the analysis of the TOPSAR data of Fernandina Island. This image shows a digital elevation model for the summit caldera which has been shaded so that high areas are light tones, and low areas are dark tones. The depth of the summit caldera is over 1,100 meters. Data processed by Howard Zebker, Harold Garbeil, and Pete Mouginis-Mark.

Fernandina - Different Viewing Perspectives (165K image)
Although a single lighting geometry can aid in the interpretation of topography, it is often more informative to try several different viewing perspectives, such as those shown here. The summit of Fernandina is shown under three lighting directions at 120 degrees to each other. Data processed by Howard Zebker and Harold Garbeil.
