GML(Geography Markup Language) is a geo-spatial data transfer form which is much suitable for web,and it is easy to understand and accept also. In this paper, based on a special data model, we designed a GML application schema document coinciding with GML3 standard through extending and assembling OGC GML3's criterion. Furthermore, a corresponding GML data file is generated. Some typical elements in this schema document are shown in xml with corresponding comment. The schema document can act as verifying basis for all the corresponding GML data files and serve for the foundation of the source codes written to read or write these data files. It's principle could be used to design another GML application schema for special purpose.
