Landslide Inventory Mapping Using Airsar Data and Optical Satellite Images in Cameron Highlands Area, Malaysia
Landslide hazard is more critical for human settlement at hill sites, particularly in tropical countries like Malaysia
where heavy precipitation can causes landslides. In the landslide inventory map including all 92 landslide locations was
created based on numerous resources such as digital aerial photographs, AIRSAR data, WorldView-1, SPOT 5 satellite
images, and field surveys. The results indicated the accuracy of SAR data and optical satellite images using the root mean
square error (RMSE) method was 0.163, which indicate acceptable agreement relating to landslide points detected and the
current data from landslide areas.
