Landsat Thematic Mapper and SPOT imagery are complemented by Synthetic
Aperture Radar (SAR) data. In addition to the backscatter radar images,
we have applied SAR Interferometry to produce a 20 meter pixel digital
elevation model (DEM) of the Dead Sea fault system from the Jordan Valley
northward until the junction with the East Anatolian fault. This
high resolution DEM, in conjunction with other high resolution imagery,
is being used for regional mapping of the Dead Sea fault system, as well
as morphometric analyses to identify the possible distribution of neotectonic
deformation. Some remote sensing examples are shown below.

extent of SAR data (provided by ESA). Both ascending and descending
orbits were used to image rugged parts of the terrain that result in layover,
foreshortening, and shadowing.
interferogram is shown at the left. Topography is the primary influence
on this interferogram, and each color fringe can be thought of as a contour
with an interval determined from the satellite baseline.

The DEM was derived from interferometric processing of synthetic aperture
radar (SAR) imagery.
