Utilizing Remote Sensing and Digital Image Processing to Delineate the Structural Features in the Eastern Part of the Dead Sea, Jordan

Abstract

Digital image processing techniques were used for mapping structural features using a medium resolution image (ETM+) from Landsat 7. The aim of this study is to utilize remote sensed data and digital image processing techniques for updating the structural map in the north eastern part of the Dead Sea (Ma’in area), Jordan. The study area is becoming an important target for geological survey activities, mineral exploration and industrial investment. This area was chosen for conducting a study based on satellite imagery interpretation of Landsat Thematic Mapper (ETM+). A special attention has been given in this study to the textural analysis techniques and the methods of image enhancements of Landsat (ETM+) images. As a result, a new lineament map was produced that represents the subsurface geological features and structures using visual interpretation and digital image processing by utilizing different enhancement techniques. A map showing the old structural features at a sub-regional scale has been produced together with a map showing the new structural features as interpreted from Thematic Mapper images.
