Disaster monitoring and early-warning system for snow avalanche along Tianshan Highway

Abstract

In this paper, a pilot study on the establishment of snow avalanche disaster monitoring and early-warning system based on the case study of area along the Tianshan Highway is presented. Prototype system design method is introduced into the whole process of early-warning system design and development based on the analysis of snow avalanche occurrence mechanism. Snow avalanche disaster databases and snow avalanche danger analysis model library are constructed, and the early-warning system which integrates the interfaces of database Access and model library access is developed by ArcGIS Engine 9.2 and can carry out the full workflow of early-warning information publication service. The Analytic Hierarchy Process (AHP) method is introduced in building snow avalanche danger analysis model which is incorporated into early-warning system.
