Generating 1 meter contour from ASTER-GDEM for monitoring landslide in Merapuh area

Abstract

This paper documents the process of generating high spatial resolution contour of one meter from ASTER GDEM (Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Digital Elevation Model) data by combining the Remote Sensing and Geospatial technology using ERDAS IMAGINE 2014 and ArcGIS 10.2 software. The study area is Merapuh, Pahang due to its variety in elevation of the earth surface. The ground verification survey also was executed to ensure the reliability of the contour generated besides gathering additional data by conducting levelling survey to see the differences of elevation on the area. The one meter contour produced in this paper will be overlay with other relevant data such as landslide history, land use and land cover, aspect, Digital Elevation Model (DEM) and others for the purpose of monitoring landslide in the area later. © 2014 IEEE.
