GIS Based System Integrated with Spatial Image Processing Function for Disaster Reduction

The disaster reduction systems are most based on GIS, and the core idea of those systems is the past earthquake experiences. Remote sensing image processing can help government assess earthquake damage quickly. Taking this technology integrated with the quondam system can improve the assessment´s precision of this kind of system. In this paper, the technology means and prospect of using RS technology to quickly evaluate the earthquake damage have been discussed. Firstly, three earthquake damage cases are presented to show the possibility and problems in quick evaluation of earthquake damage by means of GIS based system. Secondly, a result of Bachu earthquake damage by RS is put forward to illustrate the application prospect of earthquake damage quick assessment. Thirdly, integrating the image processing module with the old system to get the new system REPDRS, in which the assessment´s precision can be improved.
