Sharing method of map symbols based on XML Web services
地图符号的XML Web Services共享方法

In this paper we aim at symbol sharing. First, we analyze two methods of symbol sharing.Second, we investigate the construction principals of map symbols for the difference issues of symbol design patterns.The PostScript imaging model will be introduced and an XML-based symbol representation mode is being proposed as well. Third, due to the discrepancy of symbol usage environment and symbolic interface, a web services based distributed sharing method for map symbol data and functions is presented. Finally, a prototype system for symbol sharing is being built to validate the feasibility of map symbol service sharing.
