| Abstract: | Damage estimation caused by an earthquake is a major task in the post-disaster mitigation process.To enhance the relief and rescue operation in the affected area,it is required to receive rapid and accurate knowledge about the conditions of damaged area.Remote sensing techniques were proved to be useful in the last decades in detecting,identifying and monitoring the impact and effect of natural disasters.Recently emerging LiDAR data provide the height of the ground objects,which can be used to extract the c... |
