Paper Abstract

The study site is selected in a Malaysian tropical rainforest area, which consists of a mixture of plain, hilly and mountainous terrain. Digital Elevation Model (DEM) images were generated from nine RADARSAT-1 imageries (F, S and W beam modes) which make up six stereo pair combinations. The DEM accuracies for all the stereo combinations have been validated and compared to each other. The results show that numerous factors affect the final DEM accuracy. In flat areas, the final DEM accuracy is highly correlated to the stereo intersection geometry of the different image combinations. The higher the stereo intersection angle of the same beam mode, the better the accuracy of the final DEM.
