Abstract

Digital terrain attributes derived from digital elevation model (DEM) such as elevation, slope, and aspect are widely used to determine the influence of topography on different environmental and human processes. 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 ASTER GDEM and SAGA functionality of QGIS, and R software to develop terrain maps for Marinduque, an island province of the Philippines.
