摘要:
针对地震数据的特点,提出WebGIS和虚拟现实技术两者相结合,建立防震减灾系统。首先分析了三维WebGIS的两种常用模型,通过对比其优缺点,指出建立基于X3D的三维WebGIS模型更有利于大型地理场景的实现,扩展性强。然后在此基础上建立了以WebGIS和虚拟现实技术为核心的防震减灾系统构架和数据库,并说明了其基本功能。
Abstract:
Based on the characteristics of seismic data,WebGIS and virtual reality technology is combined to establish Earthquake Disaster Prevention and Mitigation System.Compared the advantages with the disadvantages of three-dimensional WebGIS models,the three-dimensional WebGIS model based on X3D has more conducive to large geographic scene and the realization of strong expansion.On the basis of these,we established the framework and basic database of the system at the core of WebGIS and virtual reality technology,and explained the kinds of functions of the system.
