LDS Application for fracture networks detection from satellite

The methodologies used to characterize the structural elements have experienced a major boom in hydrogeology. It happens that these methods have limitations manifested by a high failure rate because of the risk of subjectivity. The aim is to propose a methodology for establishing a fracturing card minimizing human intervention and as close as possible to reality. SRTM (Shuttle Radar Topography Mission) images were used for this study. The Sobel filter was applied to accentuate the major litho logical discontinuities. A segment detection algorithm was applied for extracting structural features. The analysis of the orientation shows that the highest lineament density extract the SRTM image was recorded in the NW-SE direction. This helped to establish the fracturing map of Poro region.
