Litho-Stratigraphic Mapping of the Bajalia Anticline, Missan Governorate by Using Digital Image Processing of Landsat-9 Imagery

A combination of digital image processing and field works provides a vision into differentiating between the rock units, in addition to contacts among them. Landsat 9 was used plot detailed geological map study area, located Al-Teeb city at Bajalia anticline, Missan Governorate, Southeast Iraq. The included geometric correction, enhancement, classification, use false-color composite technology selection best represented by RGB 741. Band ratios were applied, which is most appropriate detecting rocks type determining dimensions formations through spectral reflectivity curve sandstone. It them (RGB 4/2, 7/5, 6/2). For purpose optimizing results band ratio, they combined color for distinguishing considerable amount information, as well conducting principal component analysis. These processors increase differences facilitate process visual interpretation because cases fingerprints terrestrial features are similar difficult distinguish, saving time effort required conduct After performing matching interpretation, good, drawing anticline.
