ABSTRACT: There are several techniques that were
developed for determining the linear features. Lineament extractionfrom satellite data has been the most
widely used applications in geology. In the present study, lineament hasbeen extracted from the digital
satellite scene (Landsat 5, TM data), in the region of Zahret Median situated
in the north west of Tunisia. The image was enhanced and used for automatic
extraction. Several directions of features were mapped. The directions of major
invoices are NE-SW and NW-SE oriented. The validation of the obtained results
is carried out by comparison with the results geophysics as well as to the
studies previous of mapping developed in the sector of study.
