Geomorphology maps, history, necessity and application

The science of Geomorphology is the study of ground surface unevenness. Geomorphology provides the best basis for classifying the ground. One of the outcomes of the work of Geomorphologists is the preparation of geomorphologic map, which is the result of long-term research efforts. The preparation of these maps always follows certain principles and methods. Obviously, in recent years, geomorphologic maps have been developed using new techniques and computer manipulations such as GIS. The important issue of geomorphologic maps is the standardization, which has been remarkable, and some action has been taken in this regard. The purpose of the preparation of geomorphologic maps is to record the information on landforms, materials, soil and rock, ground processes and, in some cases, the age of the landforms. In this way, they provide a basis for ground-based assessment that is useful in many environmental issues. Therefore, geomorphologic maps are not only a scientific and research basis for different researchers, but regarded as a tool for sustainable development and advancement. Familiarity with it, the way of drawing and its developments, the necessity and the aspect of its applicability are of significant importance.
