Preparation of contouring, hill shade and slope map of erode district by using QGIS

Abstract

Digital terrain attributes derived from digital elevation model (DEM) such as elevation, slope, hill shade, contour and other aspect are widely used to determine the influence of topography on different environmental and human processes .Contour map is mainly used for locating suitable area for providing check dams and any other construction. The advent of publicly available DEM data has provided a cheaper, low-cost alternative to traditional field data collection and survey. Handling, processing, and visualization of such data on an open-source software will provide researchers and specialists a better and faster way of generating digital terrain maps and creating input data for other analyses. This paper demonstrates the methodology of combining the use DEM and other functionality of QGIS to develop terrain maps for Erode district.
