Landslide prediction is very important in disaster prevention and reduction procedures
including spatial and temporal landslide prediction
and it is one of practical research fields to evaluate and predict landslide hazards using statistic analysis model
but the prediction result depends mostly on sample numbers and spatial distribution.The aim of this study is to analyze and compare the landslide prediction using different models in Cameron highland
Malaysia
and nine evaluation factors are selected
i.e.elevation
topographic slope
topographic aspect
topographic curvature
distance from lineament
land use and land cover
geomorphic characteristics
distance from road and drainage.Support vector machine(SVM) and logistic regression model are applied to landslide spatial prediction and mapping
and the results show that average prediction accuracy using logistic regression model is about 86.2%
but 95.9% using SVM model
at the same time
the prediction result based on SVM model is more changeless
less influenced by sample numbers.So the SVM model is commended for actual applications
and it is more efficient and accurate for landslide hazard evaluation and spatial prediction.
