云南省省级地质环境信息化应用模式探讨

Discussion on the Construction of Geological Environment Informationalization System in Yunnan Provincel

根据云南省地质环境信息化管理工作要求,对全省地质环境数据进行分析,结合Web GIS技术,采用B/S模式构建地质环境信息化系统,并对系统建设中的空间数据模型和数据转换关键问题进行探讨。系统由数据采集、数据转换和地质环境信息管理三部分组成,设计为应用层、业务层和数据层三层分布式体系,利用Arc Object、Arc GIS Engine及.Net Framework完成系统功能模块。

In combination with the practical needs of constructing the geological environment management in Yunnan Province,this paper discusses the construction plan of geological environment informationalization system at provincial level on the basis of Web GIS technology.The system consisted of three parts-data acquisition,data conversion and environment information management;adopted three-tier distributed architecture-application tier,business tier and data tier as the system framework;and used Arc Object,Arc GIS Engine and.Net Framework to complete the system function module.At last,the paper discussed the method of spatial data model design and data conversion which is the key question of system construction.
