Abstract

This document demonstrates the use of a Global Positioning System (GPS) to predict landslide hazard areas. Landslide is a general term used to describe a movement of a mass of rock, earth or debris down a slope under the influence of gravity, Cruden (1991). These occurrences cause property damage, injury, death and adversely affect a variety of resources in the disaster areas. Nowadays, GPS technology has shown that it is capable of monitoring sub-centimeter deformations of ground movement. GPS requires no line-of-sight between the stations which in turn enables it to monitor landslides even during unfavorable weather conditions, either in real-time or post-processing mode. However, the attainable accuracy of a GPS based system is limited by the satellite geometry and by systematic errors such as multipath and weak satellite geometry. This paper therefore highlights an investigation of landslide motions to produce a prediction map of mass movement using GPS mapping. The research is conducted at a small landslide area along new road from Pos Selim to Kampong Raja.
