Monitoring Ground Deformation Using Extracted DEM from Stereo-Pair Images of ALOS/PRISM


Article Preview

This paper used high resolution stereo-pair images from PRISM of Advanced Land Observing Satellite to generate high precision digital elevation model of target areas, which adopts the method of object space automatic matching and control detection. Compared with the same resolution of DEM from the other way in the same area, the paper educes the area of land subsidence and changed trend and analyzes the factors of accuracy for building DEM. The New DEM has higher precision than the standard DEM and reflects the real geomorphology. Through the experimental statistical analysis, the proposed method can be used for large areas of land subsidence and deformation monitoring, which is timeliness to explore reasons of region deformation.
