GIS与工程模型耦合应用模式研究

现有GIS的空间分析功能还很有限，无法满足工程模型的实际需要，而且大多数应用的工程模型是在没有考虑GIS的基础上发展的，因此目前基于GIS的专业分析都是将GIS的功能模块与工程分析模块耦合集成来实现。为了实现GIS与工程模型的有机耦合，在分析现有耦合应用模式的基础上，提出了基于开放式GIS的耦合应用模式，利用组件模型实现两者的有机耦合，达到数据共享和高效无缝集成。

STUDY ON THE MODE OF COUPLED APPLICATIONS WITH GIS AND ENGINEERING MODEL

The spatial analysis functions in current GIS are so limited that cannot support so many applications of engineering model. A large majority of engineering models being used with GIS are not developed with consideration to GIS. Consequently, engineering analysis model should be integrated with GIS functions to extend specific GIS-based modeling. In order to make good use of GIS coupled with engineering model, based on analyzing the current coupled way, Open GIS coupled method is put forward, which can make data shared and seamless integration efficiently.
