摘要
为了解决传统GIS软件的行业化、专业化和开发成本较高的问题,在深入研究"平台+插件"模型的本质与实现机制的基础上,设计了基于插件技术的GIS软件动态配置模型,并对模型实现中的体系结构、消息处理机制、插件间的交互和动态配置的一致性等关键技术进行了深入剖析,最后结合大型GIS平台——MAPGIS7.0给出了应用实例,验证了此动态配置模型的可行性。
Traditional GIS software faces some hot potatoes, for example, industrilization, specialization and high cost. In order to resolve these problems, based on the thorough study of essential and implementation mechanism of platform ＆ plugin model, this paper designed the GIS software dynamic configuration model, and analyzed the key technologies of system structure, software dealing with message mechanism, interactive mechanism between plugins and the coherence of dynamic configuration in the realization of GIS software dynamic configuration model. At last, combined with large-scale GIS platform （MAP- GIS 7. 0） , this paper gave the practice of this model, and tested the feasibility of GIS software dynamic configuration model.
