Dataset description

RASTER type data (ESRI GRID format), consisting of square cells of 10 m side. The Convergence Index, represents an alternative and more immediate description than the three curvature indices (in plan, section and tangential), to display the convergence/divergence of a slope. In particular, the index quantifies nondimensionally how much flow in a convergence index < 0, or divergence index (convergence index > 0). The range of convergence values varies between about 100 (maximum divergence) and about -100 (maximum convergence).
