Image Interpretation Techniques: Exposed Structures

The ability to recognize and map geological structures from remote sensing data is dependent primarily on two main factors: the level of bedrock exposure of the mapped structures and their magnitude of deformation. These factors determine: (1) the type of imagery data (i.e., monoscopic versus stereoscopic) that is required for structural mapping; (2) the kind of interpretation techniques (i. e., structural versus geomorphic) that must be employed; and (3) the level of integration with other data sets that is needed to constrain the interpretation of the image data (Fig. 3.1).
