Abstract

Topography of the earth surface plays a vital role in the distribution of water within the natural land surfaces. This includes various hydrological processes like surface runoff, infiltration and evaporation. The quantitative assessment of these processes mainly depends upon the topography of the surfaces. Many topographic features can be computed directly from Digital Elevation Model (DEM). Assessment of topography manually is generally tedious, time consuming and often subject to error. In the present paper, author has demonstrated the methodology of creating the DEM using two data set contour lines and elevation data.
