Application research on the investigation of geological hazards using remote sensing technique in Zhangjiakou territory

This paper introduces the approach and application of the investigation of the geological hazards using remote sensing images in Northwestern Hebei. How to select the types of remote sensing images and what method of remote sensing technique should be adopted for different kinds of the geological hazards are described in great detail in the paper. The investigation results of the geological hazards by remote sensing are evaluated in briefly. It is of important real value that the hidden danger areas and geological hazard’s trends are obtained by remote sensing to preventing and harnessing the geological hazards.
