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.
Basic Principal of Geological Reconstruction Geological reconstruction is a process to describe geological phenomenon consisted of topography, geological structure and lithology. Basic principal in geological reconstruction that is having topographical data that can be obtained by topographical survey or DEM data that is available in many sources, geological structure and lithology. Geological structure identification is very important aspect in studying geology. Aspect related to geological structures is landform on surface. Landform classification uses the main principal about morphological formation referring to geological processes either endogenous or exogenous. Figure 1. Geological Reconstruction Principal
