In book of Sutanto (1986), image interpretation is divided into 3 steps, detection, identification, and analysis. The approach conducted come through identification of tectonic landform elements such as fault, fold, and drainage pattern. Information of landform and geological structure are resulted to obtain the general description and the own relationship of lithology. Lithology identification is based on the approach through landform and geological structure interpretation. The following describes the steps of landform and geological structure interpretation.
