地质灾害信息系统是基于GIS技术的实现地质灾害数据管理信息化的专题型应用信息系统,重点在于解决地质灾害数据信息处理技术和灾害区划空间分析模型两方面的问题。本文在分析地质灾害数据特点的基础上,给出描述地质灾害的数据范畴,从地质灾害数据库系统建设、地质灾害数据信息标准化、地质灾害区划分析评价模型几方面阐述了地质灾害信息系统的设计思想。利用MAPGIS二次开发平台,在VC++5.0 MFC方式下进行了该系统的软件开发,对软件系统的信息流程结构、数据结构及基本功能进行了介绍。
Geological disaster information system is based on GIS technology to achieve geological disaster data management information system of thematic application information, focusing on solving geological disaster data and information processing technology and disaster zoning space analysis model two aspects of the problem. Based on the analysis of the characteristics of geohazard data, this paper gives the data category of describing geohazards, elaborates the design idea of geohazard information system based on several aspects of geohazard database system construction, geohazard data information standardization, geohazard zonation analysis and evaluation model . Using MAPGIS secondary development platform, the software development of the system was carried out in VC ++ 5.0 MFC mode, and the information flow structure, data structure and basic functions of the software system were introduced.
