摘要

With great changes in global climate and unusual and extreme weather in recent years, the geological disaster happens more frequently than ever before, so people attach more and more importance to the geo-disaster defending and decreasing for the social economic development especially after the great earthquake in Wenchuan, Sichuan province. As our nation's great strategy informational source, Geo-hazard information is the key technology in the area of government managing decision, which plays an important role in a project. How to use it has become the key problem. The development of new industry and the promotion of life conditions makes the service based on the geo-information in huge demand. Geo-hazard spatial information sharing service platform is to build a basic spatial information sharing environment. In this environment, the information will be shared in the form of Web services for government agencies, businesses, and the public, provided that geological hazard specifications and standards are followed. Actually, with the development of Internet technology and cloud computing, preliminary results have been achieved on the problem of geographic information sharing and corresponding evaluation work has been carried out. Based on the idea of disaster ontology, the geographic shared service framework is designed and expounded, which is adapted to Wenchuan zone by using data catalog rules. The geo-shared service model is derived from Geo-hazard Spatial Information Sharing Service Model. The design of service interface is expounded. The evaluation and application as well as effective system test is finished based on the Wenchuan geo-disaster evaluation and application system.
