The mapping of these geological structures improves the existing knowledge about the distribution and direction of these structures in the Kashmir Himalayan region.
The Drainage map of the study area, digitized from the Landsat ETM image, shows Trellis drainage pattern indicating that the drainage is controlled by different structural features. From the existing tectonic map of the India, Main boundary Thrust Fault (MBT) was overlaid over the lineament map and it was found that the Fault (MBT) passes through the study area in the North western direction and the maximum lineaments are either parallel or perpendicular to the fault. By the analysis of these lineaments, it was found that 48 lineaments are in NW-SE direction, 32 lineaments are in NE-SW direction, 7 lineaments are in N-S direction and 6 in E-W direction.
In all, 93 distinct linear features were identified and digitized their latitude, longitude and the direction was analyzed by rose diagram. The enhanced image was merged with the PAN image in order to differentiate between the artificial linear features such as roads, canals etc. Different edge enhancement techniques were applied on Landsat ETM to better identify the lineaments using 3x3 edge enhancement filter.

In this study, an attempt has been made to map a high resolution lineament map of northwest Kashmir valley using remote sensing and GIS technology.
