摘要
多边形叠加是地理信息系统中一种非常有用的空间分析功能。笔者针对MapXtreme Java中没有提供多边形叠加分析功能这一问题,提出了利用缓冲区分析思想实现多边形叠加中的求多边形之和的一种方法,很好地解决了项目中求多边形之和的问题,同时也为其它开发人员使用MapXtreme Java实现求多边形之和提供了思路。
polygon overlap is an important spatial analysis function in the GIS research. But MapXtreme Java of Maplnfo Company doesn＇t provide polygon overlap function. In order to solve this problem, this paper put forward a new idea and method, which made use of buffer analysis principle to realize polygon union of polygon overlap function. Moreover, this method has been applied commendably and solved the problem emerging in authors＇ project. At the same time, this method can provide a kind of idea for the other personnel who use MapXtreme Java to realize polygon union.
