摘要
在分析常用软件跨平台技术的基础上,提出了基于嵌入式GIS图形中间件和数据中间件实现嵌入式GIS跨平台的方法。通过构建嵌入式图形接口描述表、图像缓存驱动、图形缓存驱动和GDI适配器的图形中间件以及基于地理空间数据访问引擎、数据管理引擎和数据定制技术的数据中间件,满足了嵌入式GIS快速跨平台开发的需求。
On the basis of analysing the cross-platform technology used by the common software, a cross-plat- form method was put forward based on the embedded-GIS graphics middleware and data middleware. Through the graphics middleware which consisted of four parts such as the image cache driver, the graphical interface description tables, the graphics cache drive and GDI adapter, and the data middleware which consisted of the geospatial data access engine and management engine, the needs of a variety of embedded-GIS visualization un- der the quick cross-platforms and application environments were met.
