“…The surrounding mountains forming the Cherb belt show evidence for a polyphased tectonics also characterized by a modern seismic activity [9]. Remote sensing techniques have been already developed for the study of the chotts, using multispectral imagery [10], large scale optical imagery [11] or multifrequency radar imagery [12].…”

The three sensors onboard the Advanced Land Observing Satellite (ALOS) are the Phased Array L-band Synthetic Aperture Radar (PALSAR), the Panchromatic RemoteSensing Instrument for Stereo Mapping (PRISM), and the Advanced Visible and Near-Infrared Radiometer type 2 (AVNIR-2). Each of them has been evaluated for the geological mapping of the Zone of Chotts, Tunisia. Both the endoreic basins and the surrounding ranges have been studied. The 10m-resolution AVNIR-2 sensor is a good trade-off for geological mapping. The 2.5m-resolution PRISM sensor with its stereoscopic capability is very useful for the detailed study of sedimentary layers. Copolarized radar data are relevant for the study of the flat itself but the C-band is more accurate for sensing the roughness of the finer sediments (sand veneers, evaporites, etc.). The HV polarization is suitable for identifying the presence of halophytic plants that fringe the upper part of the flat.

“…Some very flat areas appear dark because they are to smooth for backscattering. These areas mainly consist of evaporites that could be discriminated using C-or X-band [12]. Other playa surfaces (evaporites, carbonates, clays, etc.)…”
