空间信息技术在堰塞湖应急处置中的应用
|
摘要
主要介绍了汶川地震中唐家山堰塞湖应急处置过程中空间信息技术的具体应用。通过收集堰塞湖发生及处置全过程中所获取的有关基础地理信息、航空航天遥感影像、地质、水文气象、资源环境、人口社会经济以及应急决策等各类数据,并对上述数据进行处理,以使相同类型的数据能在统一的格式下进行组织、存储并进行有效的数据库管理。利用Web Services、空间数据库等技术建立数据库管理信息系统,实现基于网络的各类数据的查询检索和分析功能。该数据库的建设,可为今后类似应急处置提供快速、准确和直观的基础信息和经验指导。
The specific application of spatial information technology in emergency treatment of Tangjiashan Dammed Lake induced by Wenchuan Earthquake is introduced.The related data and information are collected,including aerospace remote sensing images,basic geographic information,geological data,hydrological and meteorological data,environment and socio-economic information.After data processing,the same kind of data in a unified format can be organized,stored and managed in the database,and a web-based information system is developed based on the Web Services and space database,providing a fast,accurate and intuitive basic information and guidance.
