GIS technology as a tools to predict landslide

Abstract

This research had been carried out in Paya Terubung, Penang, Malaysia. The objective of the study is to determine and classify potential area for landslide, produce map for potential area and build a user interface. The research aims to monitor landslide using Geographical Information System (GIS). There are eight factors that contribute to landslide such as rainfall, river flow, soil type, slope, underground water, land use, erosion and mineral. A rating system with marks is given for each factor. The methodology of the study begin from data collection, transferring and processing, developing database, spatial analysis and finally result and discussion. The verification method is performed by a comparison of existing landslide. The validation result shows satisfactory between the susceptibility map and existing landslide location. Landslide Information System has been developing for user to access into the system. The proposed system will improve monitoring process and safety potential areas that involve landslide.
