The loss assessment method of building earthquake damage using The Remote Sensing and building grid data

摘要

The earthquake disaster loss assessment is of great significance for the disaster recovery and reconstruction, the resettlement and the economic sustainable development. The Remote Sensing (RS) technique can help rapidly obtain the earthquake damage information. The paper proposes a methodology and procedure of building loss assessment based on the remote sensing and km grid-based building data, and presents an application to Lushan earthquake 7.0. The comparison to the results obtained by the average method of the administrative units implicates that the proposed method would achieve the more detailed and accurate loss assessment.
