摘要
获取、存储、分析、处理地理信息的遥感图像处理系统软件、地理信息系统软件、关系数据库软件被称为地理信息工程软件。通过分析这三种软件的功能特点，认为建立集成化的地理信息工程软件结构非常必要。在此基础上提出了基于客户／服务器结构的系统软件体系结构，具体分析了基于元数据管理系统和应用程序接口（ＡＰＩ）的两种地理信息工程软件集成方式。
We call Remote Sensing Process software,Geographical Information System software and Relational Database software which capture,store,analysis and process geographical information as Geographical Information Engineering software.This article analyzes the characters of those three kinds software,compares their commercial models which were often used,and put forward an Client/Server based Geographical Information Engineering software architecture to integrate those software together.We suggest two methods of integration model——metadata based and API(Application Programming Interface)based.Metadata based integration model can reach file level integration,it is suitable for current systems based on commercial Geographical Information Engineering software integration.API based integration model can reach object level integration and stands for the future of Geographical Information Engineering software integration.
