Abstract

A service-oriented method to design and construct a database and information system for mountain hazards is proposed by analyzing the hazard environment and characteristics of debris flows, collapses, and landslides along the Sichuan-Tibet railway based on survey results. An integrated database of mountain hazards was designed and built by using Geographic Information System (GIS), Remote Sensing (RS) and database technology. Based on the ArcEngine technology of service-oriented COM component, the software platform of mountain hazards management was established to perform functions including input and update of mountain disaster data, query and analysis of mountain disasters, as well as dynamic hazard assessment and mapping. The disaster data products generated by this system will support the line selection and disaster mitigation planning of the Sichuan-Tibet Railway and provide scientific support for the further establishment of a digital disaster reduction system for traffic trunk lines.
