Research and application of planning support system based on 3S technique for post-disaster reconstruction after Wenchuan Earthquake in China

This paper first discusses the technical route for applying 3S technique in post-disaster reconstruction planning, and gives the general framework of the post-disaster reconstruction planning supporting system (PRPSS). Furthermore the database model and the function model of PRPSS is analyzed. At last the paper gives the technical methods to achieve the system and the application cases of the system in the post-disaster reconstruction planning. The practice indicates that PRPSS developed with 3S technique can be used to many aspects of the post-disaster reconstruction planning, such as the information extraction of geological disasters, disaster situation assessment, site selection analysis, thematic mapping and so on. The post-disaster reconstruction planning results can be made more scientific and rational by using PRPSS.
