摘要
嵌入式设备平台种类越来越多,为了使开发的GIS系统能在多种平台上运行,提出了一种跨平台的嵌入式GIS数据模型。该模型将与显示无关的数据处理模块独立出来,并在此基础上进一步划分为上层用户接口模型和底层数据引擎模型。该模型不仅能够满足用户二次开发的需求,还可以跨越多个操作系统,并且集成多种异构的GIS数据资源。最后,通过一个交通导航系统的实现,验证了该模型的平台无关性。
The types of embedded device platform become more and more diversified. In order to make GIS systems developed run on several kinds of platforms, this paper put forward a cross-platform embedded GIS data model. This model isolated the data processing part, which was irrelevant to display, and based on which, it was further divided into higher layer interface model and lower layer data engine model. This model is able to not only meet user＇s requirement of secondary development but also cross several operating systems and integrate several heterogeneous （;IS data resources. Finally, the platform-lndependence of the model is eertified, through the implementation of a tralffie navigation system.
