%X In order to resolve the problem of heterogeneous spatial data sharing and interoperation,a mutual conversion model of spatial data files is designed and implemented by using COM technologies.There are three subsystems in the frame of this model.This article puts forward the concept of aggregative data structure for GML in a creative way.With the help of this data structure,the arduous task of converting spatial data files can be performed easily.
