Information Management System of Landslides Triggered by Wenchuan Earthquake on 12th May, 2008: --Based on WebGIS and Database Technology

Wenchuan Earthquake triggered more than thousands of landslides, which seriously threatened the lives and properties of local people in the disaster areas. Even though emergency investigation and monitoring have been carried on after the earthquake in order to make sure the reconstruction work well, there is still need an effective way to manage the considerable disaster information immediately. This paper presents a preliminary study of a WebGIS-based approach to the representation, organization and access of geohazard information-including map & data query, statistic, spatial analysis and early warning. The system is not only to assist in the decision-making process for administrator to prevention disaster, but also to provide a platform for the more end-users with limited GIS knowledge to understand the geohazard and a cost-saving solution to access up-to-date spatial datasets customized for a specific topic.
