基于Silverlight的GIS组件的研究与开发

文章对目前GIS发展的现状作出了分析，阐述了Silverlight技术应用在GIS领域的优势，并设计出了一套基于Silverlight技术实现的组件，它包括地图绘制核心模块SilverlightMapSuiteCore．dll，用户交互模块SilverlightEdition．dll，两个模块都具有高度的可扩展性，让GIS开发人员可以方便的调用及重写来构建他们的GIS应用程序，最后文章还列举了一套基于该组件开发的车辆追踪系统，方便具有类似需求的用户进行借鉴。

The Research and Realization of GIS Component Based on Silverlight

The paper analyzes the current situation of GIS industry，illustrates the advantages of Silverlight technology over the other existing technologies in GIS solution，and in the meantime，realizes a reusable GIS component．It contains one module SilverlightMapSuiteCore．dll which is used for map rendering，and another module SilverlightEdition．dll which is used for user interaction．Both of these two modules are very flexible，so the customers can build their own applications by consuming and overwriting them，at last，we depict a vehicle tracking system which is developed based on this component to provide reference for the customer who have similar requirements．
