基于Web的灾情信息可视化研究

Visualization Research of Disaster Information Based on Web

本文利用WebGIS的优势,研究了灾害信息的Web发布、检索和可视化的关键技术,主要涉及到异质异构数据的集成和数据的分布式检索融合技术,并对他们进行了详细地阐述;最后建立了灾害信息的Web发布和可视化系统,用户可以清楚地在地图上了解到灾情信息以及灾情动态变化的过程,对灾害的评估与防止具有重要意义。

The paper studied the key technology of the web publishing of disaster information, search, and visualization by advantage of WebGIS, which mainly involves integration of different data and dis-tributed search and fusion of data, and they were expounded in detail. Finally, we established a web publishing and visualization system of disaster information, and the user can clearly understand disaster information and the dynamic change process of disaster on the map, and then this system is of great significance for disaster assessment and prevention.
