An Adaptive Automatic Algorithm for Extracting Geological Lineaments in AL-Dibdibba Formation Basin

Abstract

Iraq is one of the Arabian area countries, which considered from the drier areas on the earth, though it has two main rivers that pass through(Tigris and Euphrates); it suffers the same problem as them (drought), only the rivers' nearby regions make use of their water for (domestic, agricultural, and industrial purposes(.One of the usable solutions is to utilize the groundwater (especially in the desert regions). Using the Remote Sensing and geographic information system is a rapid and coast effective techniques, they provide information of large and inaccessible area within short span for assessing, monitoring, and management of groundwater resources. In this study, an adaptive algorithm based on Canny edge detector noise reduction idea and directional filters scheme submitted for lineaments automatically extraction from LandSat7 (Enhanced Thematic Mapper Plus) ETM+ band 7 data considering the lineaments spatial and spectral characteristics, yet the algorithm validation examined using ancillary data of the same interest (Iraq tectonic map and 90m SRTM DEM). The analysis process achieved using Arc GIS 9.3 to recognize the potential groundwater renewal and/ or accumulative zones in the selected arid to semi-arid area (AL-Dibdibba formation basin).
