Mapping potential landslide using digital terrain model: application in Ringlet Forest Reserve

Cameron Highland is one of the landslide prone areas in Malaysia where Ringlet is a hotspot location that is tagged as high landslide frequency. Ringlet Forest Reserve (RFR) is one of the water catchment areas in Cameron Highland which collects rain water by its natural landscape...
