I m working neotectonic and i want to determinate intense lineament of my project area with DEM.
Thank you for your helps, kind regards.
i think you will get this video is very useful

you will need PCi Geomatica software, to use line algorithm.
Firstly thank you for your attention. Abdullah TarekMohammad i watched that video before . He is using 8 bit gray scale image but i want to use DEM so i think i need different method for create a lineation map.
If you're using a DEM, you need to create a Hill shade map of the DEM in different solar elevation and illumination directions. These parameters are dependent on your geographic location and It is advisable that illumination directions are perpendicular to major regional lineament directions of the area. Doing this promotes lineaments identification as different views of same area is highlighted.
Some authors detect tectonic lineaments analyzing slope and aspect. This can be done in arcgis.
Hello:
By using the software ENVI , you can build the different models of Topography such as; Shaded relief, profile convexity, plan convexity, longgitudinal convexity, cross section, Min and Max Curvature, RMS Error
In addition, you can use different filter directional in ENVI software for to detection of linear elements from DEM.
