Thematic Mapper analysis to identify geomorphologic and sediment texture of El Tineh plain, north-western coast of Sinai, Egypt

Thematic Mapper data combined with field inspection are successfully applied to detect a wide variety of texture analysis of sediments and geomorphologic variability along the coastal plain of El Tineh bay at the north-western part of Sinai. Processing techniques used in this study include: image enhancement, principal component analysis (PCA), TM band ratios and supervised classification. The analysis of colour composites of PC1, PC2 and PC3, always encoded red, green and blue, respectively, combined with a colour composite of 3/1, 4/3 and 7/3 ratio images and supervised classification serve to identify six main geomorphologic features and also discriminate among 14 sediment textural classes along El Tineh coastal plain.
