摘　　要：为了解决现阶段不同GIS平台间的数据共享问题,采用集合论和符号学方法对各类地理要素在不同GIS平台的不同的表达方式,提出了基于嵌套的地图符号树状结构描述、符号解析以及符号映射的机制,在此基础上通过制定模版以实现不同GIS平台间的数据共享。实践表明:这种方法能够实现多个GIS平台间的数据共享,具有开放性、实用性的特点。In order to settle the issue on data-sharing among different GIS platforms,taking different representations of same geographical features among platform into account,the description of map symbol based on nested tree-structure,the mechanism about symbol parsing and symbol mapping were proposed,which were based on mapping theory,furthermore,a set of template on the basis of it was suggested,intended to reaize the data-sharing among platforms.It has been proved that data-sharing could be reached by the technique,characterized open and practical.
