Abstract
Remotely sensed data often used to study terrain surface, thus unique geomorphic and geologic features can be identified. The processing of satellite images is successfully utilized in this respect. Therefore, are com- monly known among these features. They are observed as linears on satellite images and usually represent fracture traces, faults or lithologic boundaries. These systems are well utilized in the interpretation of several hydrogeological and tec- tonic criteria. This study introduces the procedure of identifying linear features in Wadi Aurnah basin (3100km 2 ), of the Arabian Peninsula. Hence, the lineaments map for this catchment was produced. For this purpose, ASTER satellite images were treated using ENVI4.3 and ERDAS Imagine software. Consequently, the obtained map was analyzed using GIS tech- niques to interpret the behavior of the existing lineaments and their spatial distribution. This will provide valuable infor- mation that can be used in several studies related to water resources management in this basin, which is under water stress.
