GIS technology as a tools to predict landslide

Abstract

These research had been develop in Paya Terubung, Penang, Malaysia. The objective of the study are to determine and classify potential area for landslide, produce map for potential area and build a user interface.The research aims is to monitor landslide using Geographical Information System (GIS). There are eight factors that contribute to landslide such as rainfall, water 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 perform by comparison of existing landslide. The validation result show satisfactory between the susceptibility map and existing landslide location. Landslide Information System has been developing for user to access into the system. With this system, it will increase monitoring process and development that involve landslide.
