TERRAIN ANALYSIS IN CONSIDERATION OF SURFACE CURVATURE CONDITIONS

Abstract

In digital relief models determination of the terrain curvature can be realized without difficulty with the aid of the formulae figuring in the paper. Visualizing the results on maps, the curvature conditions can also be studied visually. After a computer aided analysis of the results the algorithm in the paper orders the surface points into seven categories (plane, peak, pit, pass, ridge, valley, slope) and/or their sub-categories. In a digital form, the resulting image matrix can supply further computer aided processes ,with information, and visualized in a graphic way it gives a good image about terrain formation. The results can be utilized in different branches of agricultural planning, in environmental protection, hydrological modeling, etc.
