| Abstract: | Aerial photographs are invaluable for study of terrain characteristics which are reflected in the morphology-form and association of different physiographic units in any area. Based on environmental controls of geology, relief, dominant geomorphic process and climate, a system of landscape classification has been evolved. Characteristic physiographic units in any area are identified and defined based on their form, slope variations, orientation, spacing, surficial deposits and water regime. Only two units i.e. landscape pattern and facet are adopted in the classification system. The dominant aeolian process evolves a variety of forms and associations. The most important forms evolved are long sandy ridges with variation in spacing and directions, shifting sand dunes-both scattered and in clusters and various combinations of short sandy ridges. The paper describes the form, assocation and characteristics of one of the landscape patterns classified in the desert area. The norms established on the basis of aerial photo-interpretation thus help to infer terrain characteristics at different places where the pattern occurs. |
