The Application of Remote Sensing Techology to Inverstigation of Geological Hazards in Hanyuan County

Hanyuan county has the frequent geological hazards,which seriously threat to people's lives and property.Remote sensing technique has the good effect,and is strong macroscopically,its information rich and so on,may reflect really the geological hazards thus as it was is.So the remote sensing already became one important computing method which is used to the geological hazards investigation.Using SPOT5 image and Quickbird image,through certain image processing method,obtain a remote sensing interpretation base map of geological hazards,using computer assisted visual interpretation method in combination with the ground investigation,may fast verify the Luding county geology hazards,their distribution,scale and harm comprehensively,thus raise the efficiency and precision of geological hazards investigation,and achieve a quite good application progress.
