| Abstract | In order to evaluate the supervised classification in discrimination of geological materials, the study intends to deal with Landsat ETM+ images to define the spectral behaviors of lithologic components and determine the adequacy of Maximum-Likelihood Classification (MLC) in discriminating various sedimentary rocks including limestone and clay deposits in Shaikh Ibrahim area, northwestern Iraq. The proposed strategy is based on color composite ratio, Principal Component Analysis (PCA), preliminary classification of Spectral Angle Mapper (SAM), and MLC. The combination of image ratios mostly cannot differentiate the sensitivity variations of weathering products of parent materials. Whereas, PCA works toward better result in categorization of most components occurrences, SAM identifies accurately the responses of several endmembers including spectral perceiving of two types of limestone. MLC discriminates significantly the configuration and lithologic-contents of various geologic formations, where they are dominated spectrally by considerable areas of carbonates (42.54 %) in addition to clay and scree deposits (22.89 %). The spectral behavior of carbonate, clay, gypsum, and iron-bearing materials are the main spectral component types in the study area which meet a reliable lithologic discrimination by using Landsat ETM+ imagery. The study result compares favorably with the available geologic map of the study area and the reconnaissance field trip’s views of lithological classes supported the discrimination result. MLC shows considerable power in discrimination of sedimentary lithologies with 100 % accuracy when interactive preliminary classification of SAM is considered. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
