摘要
现有的GIS软件中通常提供一定数量的地图投影方式供用户选择,地图投影选择是一个复杂的系统问题,需要考虑多方面的因素,对投影的各种参数进行评估,没有现成的公式、方案或规范可以遵循。本文通过分析地图投影选择问题的信息层次,论述了专家系统解决地图投影选择问题的可行性,讨论了详细的系统建立方法,并通过COM技术实现了地图投影选择的专家系统,并将系统与专业的GIS软件集成,为地图投影选择问题提供了一条解决思路。
Map projection selection is a complex, systematic process involving a comprehensive understanding of projection characters, which can not be completed by common GIS users. However, GIS software packages on the market only show a list of map projections from which the user has to choose one based on their limit projection knowledge. The paper presents an expert system integrated with ArcGIS, on the basis of analyzing the related factors for selecting map projection. Common Object Model （COM） technology has been used to integrate the expert system with ArcGIS.
