基于WebGIS的区域地质灾害灾情动态评估系统的实现技术研究

Study on Implementation Technology of Regional Geological Hazard Dynamic Evaluation System Based on WebGIS

从湖北省地质灾害灾情评估现状出发,阐述基于WebGIS的地质灾害灾情动态评估的主要技术路线、系统架构以及技术实现,将地质灾害灾情评估模型与WebGIS相结合,实现用户零客户端方式在IN-TERNET上开展地质灾害灾情评估工作。并提出供全省统一的各类地质灾害灾情评估模型及其评估因子,可保证评估过程的可视化、实时化。

Starting from status of geological hazard evaluation in Hubei Province, the main technical route, system architecture and implementation technology of geological hazard dynamic evaluation based on WebGIS are proposed. Geological hazard evaluation model is combined with WebGIS to achieve that,the users can assess the hazard in internet by means of zero client. In the paper, the authors provide an evaluation model and factors for various types of geological hazards in Hubei Provinc.e,which can ensure the visualization and real-time implementation in evaluation process.
