Application of Electronic Sand Table System in Geological Disasters Meteorological Service Based on GIS

摘要

With complex terrain and developed economy,Zhejiang Province has suffered a lot from the frequent geological disasters,which have done great damages to the construction and development of the whole province. Therefore,it is particularly important to improve the geological disasters meteorological service. Electronic sand table system,a high-tech product of three-dimensional visualization,can provide the geological disaster meteorological service with the intuitive and visual application environment. In this study,we developed electronic sand table system based on GIS and established the geological disasters meteorological service database. In addition,we also analyzed and discussed the applications of meteorological service in online weather forecast,meteorological warning message,and multimedia meteorological electronic display. The application of electronic sand table system in geological disaster meteorological services for disaster prevention and mitigation is of great importance that it provides intuitive terrain analysis data for the forecast of geological disasters warning,which greatly enhances the ability of geological disasters meteorological service.
