摘要
3S技术已成为地学数据获取、管理、可视化与分析的重要工具。川藏公路灾害信息系统综合了遥感技术、地理信息系统技术和数据库技术,在系统设计开发过程中妥善处理数据组织与维护、数据显示与分类、多专题信息提取、文档信息与地图信息紧密结合等重要环节,这些环节不只是川藏公路灾害信息系统中要解决的问题,也是诸多GIS应用软件的共同特征。川藏公路灾害信息系统的开发,实现了对川藏公路灾害信息管理与维护方便快捷、信息共享以及辅助研究人员对川藏公路沿线灾害进行研究与治理,并且可以将相关资料发布到网上供公众浏览。
3S technologies have been very important to geo-data collection, management, visualization and analysis. The Sichuan-Tibet Highway hazards information system based on RS, GIS and DBMS, and well treated some vital problems such as data organization and maintenance, data visualization and classification, multi-theme info abstraction, multi-type data integration, etc. These problems have become common features to many GIS applications. The development of The Sichuan-Tibet Highway hazards information system make the management and maintenance conveniently and quickly for the Sichuan-Tibet highway disaster information. The Sichuan-Tibet Highway hazards information system could help researchers to study and father the disasters of the Sichuan-Tibet Highway. The correlative data also could be issued on the net fo public.
