摘要
The huge earthquake of magnitude 6.3 had occurred at Bam city of southeastern Iran on December 26, 2003. We applied nonlinear mapping method for detection of collapsed building area due to Iran earthquake with high-resolution QuickBird satellite images. As a result, ROC evaluation based on the result of photo interpretation by operator showed that the detection ratio of the proposed method is 75-90% of changed area with 20% of false alarm.
