摘　　要：坐标系统的转换参数通常不能对外提供,故GIS应用中的坐标实时转换问题难以解决。本文在分析WebService技术的基础上,提出了基于WebService的坐标实时转换方案,将坐标转换参数和公式封装成WebService,以能在Web服务器端提供实时的坐标转换服务。为GIS应用中坐标系统实时转换问题提供了一个解决思路。The transformation parameters of coordinate system usually can not be provided to the outside,so the problem that coordinate is real-timely converted in GIS application is difficult to solve.In this paper,after analyzing webservice technology,the scheme of real-time transformation has been proposed,which is based on webservice.The parameters and formula of coordinate transformation is packaged into webservice,and the real-time coordinate transformation service in the server-side can be provided.the new idea put forward in the paper has some reference,which is about real-time transformation of coordinate.
